Ramanpreet Nara 80f64f1e5b Ensure ImageLoader is lazily loaded as necessary
Summary: In D16805827, I moved ImageLoader to CoreModules. In the process, I migrated usages of `[_bridge moduleForClass:[RCTImageLoader class]]` to `[_bridge moduleForName:@"ImageLoader"]`. These two APIs aren't equivalent, however, since `[_bridge moduleForClass:[RCTImageLoader class]]` by default lazily loads the requested NativeModule, but `[_bridge moduleForName:@"ImageLoader"]` doesn't. So, I had to explicitly set `lazilyLoadIfNecessary` to `YES` in all the call-sites I migrated, to ensure that ImageLoader is correctly initialized when necessary.

Ramanpreet Nara bf78d7969a Migrate RCTImage NativeModules to CoreModules
Summary:
This diff moves RCTImageLoader, RCTImageEditingManager, and RCTImageStoreManager to CoreModules. This is necessary for us to convert all these NativeModules to TurboModules.

**Note:** As a part of this diff, I had to break apart `RCTImageLoader.h`. All the protocols that were in `RCTImageLoader` are now in their own headers. Furthermore, `RCTImageLoader`'s methods are defined in `RCTImageLoaderProtocol`, so that we can call them from classes like `RCTImageViewManager` in `RCTImage`.

jsfu 71d7d6883c fix display problems when image fails to load (#25969)
Summary:
This problem was also affecting Fabric and was fixed in D16708532.
When the image resource is changed and the new image resource fails to load, we expect the display image to fail to load, but the image still shows the image that was successfully loaded last time.

## Changelog

Pull Request resolved: https://github.com/facebook/react-native/pull/25969

Test Plan:
This is catalyst playground with following code P78264143.
TLDR of the code, it sets URL <Image> that is 404.

James Treanor 8131b7bb7b CocoaPods frameworks compatibility: Step 2 (#25619)
Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in https://github.com/facebook/react-native/pull/25393#issuecomment-508457700. If accepted, it will fix https://github.com/facebook/react-native/issues/25349.

It builds on the changes I made in https://github.com/facebook/react-native/pull/25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.

The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .

There are still a few breaking changes which I hope will be acceptable:

- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511040967.
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.

Still to do:

- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in https://github.com/facebook/react-native/issues/25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by 33573511f0.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �

## Changelog

[iOS] [Fixed] - Fixed compatibility with CocoaPods frameworks.
Pull Request resolved: https://github.com/facebook/react-native/pull/25619

Test Plan:
### FB

```
buck build catalyst
```

### Sample Project

Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.

You can see that it works with these steps:

1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`

The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.

### RNTesterPods

`RNTesterPodsPods` can now work with or without `use_frameworks!`.

1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.

Eric Lewis 3b67bfab1e Animated image improvements (#24822)
Summary:
The goal of this PR is to improve the pipeline currently used for displaying GIFs / animated images on iOS. It is achieved by not holding all of the decoded frames in memory at the same time, as well as happily releasing existing memory whenever possible. This code is a simplified version of what you would find in SDWebImage (it is nearly 1:1, with unsupported or uneeded things removed). By adopting this API, it also allows classes conforming to RCTImageURLLoader or RCTImageDataDecoder to return any decodable UIImages conforming to RCTAnimatedImage and have improvements to memory consumption. Because RCTAnimatedImage is just a subset of the SDAnimatedImage protocol, it also means that you can use SDWebImage easier with Image directly.

A nice to have would be progressive image loading, but is beyond scope for this PR. It would, however, touch most of these same parts.

Samuel Susla 51990014eb Add border properties to `RCTImageView`
Summary:
Second attempt at adding border properties to `RCTImageView`.

Previous attempt can be found at D14875673 which was reverted.

1. `UIImageView` is no longer laid out in in `layoutSubviews`.
2. `updateWithImage` was not being called, I instead of calling `self.image = image` I was calling `_imageView.image = image` directly which skips calling `updateWithImage`. This meant that image's rendering mode was not changed to `template`.

Samuel Susla 66a294032a Add border properties to RCTImageView
Summary:
`RCTImageView` is now a subclass of `RCTView` and includes `UIImageView` as it's subview.

This enables the use of `borderRadius`, `borderWidth`, `borderColor` properties and all of their derivatives.

Possible problem:

Now `RCTImageView` is backed by two views (`RCTView` + `UIImageView`), not a single one. That's 4 `CALayers`. Possible workaround would be to insert the image directly into `self.layer.contents`.

Shir Levkowitz ced1513b62 Pass actual loaded image size to load (iOS).
Summary:
Motivation: The JavaScript image component's onLoad callback optionally
accepts dimensions width and height, allowing the parent of the image to
obtain the native size (without an extra bridge call). It was found that
the dimensions passed into this callback on iOS are frequently (0,0),
not the true native dimensions. This change ensures that the image's
dimensions are passed to the callback. (Examination of the initializer
for RCTImageSource, + (RCTImageSource *)RCTImageSource:(id)json,
indicates that not all code paths produce a size other than CGSizeZero.)

Pieter De Baets e1577df1fd Move all header imports to "<React/..>"
Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.

Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Janic Duplessis 4c83237511 Add Image resizeMode repeat on iOS
Summary:
This adds a new resize mode for iOS 'repeat' that tiles the image over it's frame. This allow to easily create a view with a repeating background pattern which there is no way to do at the moment without including a bunch of different sized assets.

I'm not 100% sure it should be a resizeMode or a separate prop but I went with resizeMode since it made more sense to me and the are not really any use cases where we'd want to use this with another resizeMode other than 'stretch'.

**Test plan**

Tested mainly by adding a UIExplorer example, also tested that changing the resizeMode prop from and to 'repeat' worked properly.

Nick Lockwood 235749ba19 Fix missing images
Summary:
Under rare and as-yet-to-be determined circumstances, images can sometimes fail to load/download and get "stuck", without producing an error.

Because the `RCTNetworkTask` for these images is stuck in the "in progress" state, they clog up the RCTImageLoader task queue, which has a limit of 4 concurrent in-progress tasks.

This was previously masked by the fact that we automatically cancelled image requests when the RCTImageView moved offscreen, but we no longer do that.

This diff adds logic to detect some types of stuck task and remove them, thereby unblocking the queue. I've also restored the functionality of cancelling downloads for offscreen images (but not unloading the image itself) so that stuck images will be cancelled when you move to another screen, instead of using up space in the queue forever.

Nick Lockwood 72b363d7fc Replaced isMainThread checks with a proper test for main queue
Summary:
As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.

This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.

I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Adam Comella ee8496f364 iOS: Support HTTP headers for source prop on <Image> components
Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:

```
<Image
  style={styles.logo}
  source={{
    uri: 'http://facebook.github.io/react/img/logo_og.png',
    headers: {
      Authorization: 'someAuthToken'
    }
  }}
/>
```

Note that the header values must be strings.

Works on iOS and Android.

**Test plan (required)**

- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

Ben Nham 71bf8a3e48 Only clear image contents on memory warning
Summary:
Some apps are complaining about flashing images when performing navigation transitions. An example issue would be:

1. Load a master list view with many images
2. Click on an image to go to a detail view
3. Go back to the master list view

At step (3), users see a number of images flash from a placeholder image back to the final image because `-[RCTImageView didMoveToWindow]` calls `clearImage` when the image view exits the view hierarchy between (1) and (2) and calls `reloadImage` (which sets the image property asynchronously) when the image view re-enters the view hiearchy between (2) and (3).

This diff fixes the issue by being less aggressive about clearing image contents. It only clears image contents when the app receives a memory warning or the app goes into the background.

For comparison, CKNetworkImageComponent in ComponentKit doesn't have this purging behavior at all.

Ben Nham 5bb5ea7135 Reload image without dispatch_async if completion handler is already on main thread
Summary:
This works with D3305161 to minimize image flashing. After D3305161, the completion handler passed to `-[RCTImageLoader loadImageWithoutClipping:size:scale:resizeMode:progressBlock:completionBlock:]` may be called back on the main queue in the case of a cached image. In this case, we want to set the image view's image property synchronously rather than on the next runloop iteration via dispatch_async. This minimizes the amount of image flashing the user sees when displaying a cached image.

The exception to this case is for blurred images. A blur can be an expensive (taking multiple ms on the CPU), so we always make sure to perform the blur off the main queue even if the image is cached and the callback came back on the main queue.

Nick Lockwood b672294858 Added RCTImageSource
Summary:
public

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.

This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.

I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

The image loader was previously returning on the main thread, which could lead to poor performance due to various call sites doing further image processing (resizing, cropping, etc.) directly in the completion block.

Summary: When `RCTImageView` is removed from the view hierarchy, it clears out its `image` to save memory. This makes sense, except that it gets removed from the window (view hierarchy) even when becoming the child of another view.

This fixes the logic so that it only clears out the image if the view hasn't been moved somewhere else within one frame.
