Summary:
Currently, our configuration of Views looks like this:
```objc
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
view.yoga.isEnabled = YES;
view.yoga.height = 50;
view.yoga.width = 50;
```
Every time that we access `view.yoga` we have to access the associated object on `UIView` to get the `YGLayout`. This adds an extra `objc_msgSend` which increases binary size, and is slight perf impact.
This diff creates a way to modify the `YGLayout` with only a single `objc_msgSend`. Here's the new syntax:
```objc
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
[view configureLayoutWithBlock:^void(YGLayout *layout){
layout.isEnabled = YES
layout.height = 50;
layout.width = 50;
}];
```
Here's the Swift version:
```swift
let view = UIView(frame: .zero)
view.configureLayout { (layout) in
layout.isEnabled = true
layout.height = 50
layout.width = 50
}
```

# CHANGELOG
|
|
|
|
The changelog for `YogaKit`.
|
|
|
|
1.2.0 (**upcoming release**)
|
|
-----
|
|
|
|
### Breaking Changes
|
|
|
|
- `applyLayout()` has now been changed to `applyLayout(preservingOrigin:)`.
|
|
|
|
- Computed properties are no longer reflected in getter's of the affected properties.
|
|
```swift
|
|
// OLD
|
|
view.yoga.margin = 10
|
|
view.yoga.marginTop // 10
|
|
view.yoga.marginLeft // 10
|
|
|
|
// NEW
|
|
view.yoga.margin = 10
|
|
view.yoga.marginTop // 0
|
|
view.yoga.marginLeft // 0
|
|
```
|
|
|
|
### Enhancements
|
|
|
|
- Pixel Rounding now uses `roundf()` instead of `round()`.
|
|
|
|
- There is now a method that allows "bulk" updates to YGLayout.
|
|
```objc
|
|
[view configureLayoutWithBlock:^(YGLayout *layout) {
|
|
layout.isEnabled = YES;
|
|
layout.width = 50;
|
|
layout.height = 50;
|
|
}];
|
|
```
|
|
|
|
```swift
|
|
view.configureLayout { (layout) in
|
|
layout.isEnabled = true
|
|
layout.width = 50
|
|
layout.height = 50
|
|
}
|
|
```
