Xcode custom segue animation
提问by Jonas Ester
I have a problem with the transition animation between two storyboard controllers. I have a singleView project with two view controllers in the storyboard.
我对两个故事板控制器之间的过渡动画有问题。我在故事板中有一个带有两个视图控制器的 singleView 项目。
Now I wand to make a custom transition animation:
现在我想制作一个自定义的过渡动画：
- my current view controller should disappear to the left
- the new view controller should come from the right
- 我当前的视图控制器应该消失在左边
- 新的视图控制器应该来自右边
I have already a UIStoryboardSegueclass.
我已经有UIStoryboardSegue课了。
But what should I write in the -(void)perform{}method??
但是-(void)perform{}方法里面应该写什么呢？？
Thanks a lot,
非常感谢，
Jonas.

For that simple segue you can try something like this:
对于那个简单的转场，你可以尝试这样的事情：
- (void)perform {
UIViewController* source = (UIViewController *)self.sourceViewController;
UIViewController* destination = (UIViewController *)self.destinationViewController;
CGRect sourceFrame = source.view.frame;
sourceFrame.origin.x = -sourceFrame.size.width;
CGRect destFrame = destination.view.frame;
destFrame.origin.x = destination.view.frame.size.width;
destination.view.frame = destFrame;
destFrame.origin.x = 0;
[source.view.superview addSubview:destination.view];
[UIView animateWithDuration:1.0
animations:^{
source.view.frame = sourceFrame;
destination.view.frame = destFrame;
}
completion:^(BOOL finished) {
UIWindow *window = source.view.window;
[window setRootViewController:destination];
}];
}
