怎么使用自定义segue，实现波纹跳转

modal无法实现，push可能能够实现。

modal

presentModalViewController：animated：completion：^(void){ //code };

dismiss方法

dismissModalViewControllerAnimated:                 // 将要废弃，不赞成继续使用
dismissViewControllerAnimated:completion:

CustomSegue

-(void)perform{

CATransition* animation = [CATransition
animation];
[animation
setDuration:0.5f];

[animation setType:@"rippleEffect"];//波纹效果
@“rippleEffect”

[animation setTimingFunction:[CAMediaTimingFunction
functionWithName:kCAMediaTimingFunctionEaseOut]];

[[[self.destinationViewController
view] layer]
addAnimation:animation
forKey:@"transition"];

[[self
sourceViewController] presentViewController:self.destinationViewController

animated:NO

completion:Nil];

}

push
