KWTransition

Experimental Implementations of UIViewControllerAnimatedTransitioning.

Requirements

Objective-C ARC
iOS 7 or above

Installation

Cocoapods

pod 'KWTransition'

###Manual

You can manually install this library by copying the KWTransition.h and KWTransition.m into your project.

Usage

Import the header.
```
 #import <KWTransition.h>
```
Implement delegate transitioning delegate on the initial view controller (the one doing the presenting).
```
 <UIViewControllerTransitioningDelegate>
```
Implement a transition manager property on the initial view controller.
```
 @property (nonatomic, strong) KWTransition *transition;
```
Be sure to initialise the manager somewhere.
```
 _transition = [KWTransition manager];
```

Set the controller to use custom presentations

 [self setModalPresentationStyle: UIModalPresentationCustom];

Implement the transitioning delegate

 #pragma mark - UIVieControllerTransitioningDelegate
 - (id <UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented
 						                                           presentingController:(UIViewController *)presenting
                                                                        sourceController:(UIViewController *)source {
     self.transition.action = KWTransitionStepPresent;
     return self.transition;
 }
 -(id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed {
     self.transition.action = KWTransitionStepDismiss;
     return self.transition;
 }

Select your animation and present!

 self.transition.style = KWTransitionStyleFadeBackOver;
 KWModalViewController *VC = [[KWModalViewController alloc] init];
 VC.transitioningDelegate = self;
 [self presentViewController:VC animated:YES completion:nil];

##Styles

All styles support the KWTransitionSettingReverse setting.

####KWTransitionFadeBackOver

####KWTransitionRotateFromTop

####KWTransitionStyleUp

####KWTransitionStylePushUp

####KWTransitionStyleFall

####KWTransitionStyleStepBackScroll

####KWTransitionStyleBounceIn

####KWTransitionStyleDropOut

####KWTransitionStyleStepBackSwipe

####KWTransitionStyleSink

Supports: KWTransitionSettingDirectionRight, KWTransitionSettingDirectionLeft, KWTransitionSettingDirectionDown, KWTransitionSettingDirectionUp and KWTransitionSettingReverse.

Sample is using: KWTransitionSettingDirectionDown

Settings

You can manipulate the way some transitions behave by setting the manager's settings property. e.g,

manager.style = KWTransitionStyleSink;
manager.settings = KWTransitionSettingDirectionUp | KWTransitionSettingDirectionRight | KWTransitionSettingReverse;

Would result in the transition operating against the top right corner performing the present and dismiss in reverse animation.

Below are the available settings. As not all styles support or settings (yet), please refer to the style documentation found at the start of this document for specific style support.

typedef NS_OPTIONS(NSUInteger, KWTransitionSetting){
    KWTransitionSettingNone = 0,
    KWTransitionSettingDirectionRight = 1 << 0,
    KWTransitionSettingDirectionLeft = 1 << 1,
    KWTransitionSettingDirectionDown = 1 << 2,
    KWTransitionSettingDirectionUp = 1 << 3,
    KWTransitionSettingReverse = 1 << 5
};
