Summary:
We currently wait until after views have been updated on the main thread before sending layout events. This means that any code that relies on those events to update the UI will lag the atual layout by at least one frame.
This changes the RCTUIManager to send the event immediately after layout has occured on the shadow thread. This noticably improves the respinsiveness of the layout example in UIExplorer, which now updates the dimension labels immediately instead of waiting until after the layout animation has completed.
Summary:
Currently, the system for mapping JS event handlers to blocks is quite clean on the JS side, but is clunky on the native side. The event property is passed as a boolean, which can then be checked by the native side, and if true, the native side is supposed to send an event via the event dispatcher.
This diff adds the facility to declare the property as a block instead. This means that the event side can simply call the block, and it will automatically send the event. Because the blocks for bubbling and direct events are named differently, we can also use this to generate the event registration data and get rid of the arrays of event names.
The name of the event is inferred from the property name, which means that the property for an event called "load" must be called `onLoad` or the mapping won't work. This can be optionally remapped to a different property name on the view itself if necessary, e.g.
RCT_REMAP_VIEW_PROPERTY(onLoad, loadEventBlock, RCTDirectEventBlock)
If you don't want to use this mechanism then for now it is still possible to declare the property as a BOOL instead and use the old mechanism (this approach is now deprecated however, and may eventually be removed altogether).
Summary:
Supports `onLayout` for Touchable*` by piping onLayout
through to the native component inside since only native components support
it by default.
Summary:
Now that UITextViews have a delegate, they consume the "tap to scroll to top" gesture. This diff restores the original behavior of letting the top-level scroll view (if any) scroll to top instead.
I tried exposing scrollsToTop as a prop and was semi-successful in that I could turn scroll-to-top on and off for the top-level scroll view scroll, but the text view itself would never scroll to top. So instead of exposing it as a prop, this diff sets scrollsToTop always to NO, which is how TextInput behaved previously.

Summary:
1) Makes params more intuitive (only one now, bounciness, which maps intuitively to number of oscillations).
2) Satisfies boundary conditions (f(0) = 0, f(1) = 1) so animation actually goes where you tell it (before it would finish at a random location depending on the input params).
3) Simple test to verify boundary conditions.
Summary:
This will throw an error message with the problematic callback module/method. Previously we would get an invariant in this case when we try to access `callback.apply` later in the method.
Summary:
TabBarItemIOS supports setting the scale for base64-encoded images using an optional scale parameter, however this was broken due to the JS code only passing the uri, not the whole source object, to the native side.
(See: https://github.com/facebook/react-native/issues/2413)
Summary:
We want to be able to access the touch data within our components' event handlers, so we need to thread the event object all the way through to them.
Summary:
require('./image.jpg') returns a number and therefore the propType is wrong. Adding it to the propType to fix the warning and dealing with flow which is completely broken for this.
Summary:
The test runner relied on checking the current error message in the RCTRedbox, which is a singleton (yay, shared mutable state!). This lead to some tests that worked individually but failed when run together due to error messages in RCTRedBox left over from previous tests.
I've replaced the call to -[RCTRedBox currentErrorMessage] by injecting a custom logging function to intercept the errors at source, which is a much more reliable solution.
