uiview - How Do I Properly Animate SubView's Center Point with Rotation -


I have two UIViews (A and B) as the subviews

I'm going to animate View A for a UIViewcontroller main view (supervision) Trying (to scale / rotate) / Move to the center of

View B If I scale / rotate the animation is smooth. If I simply have the center point animation is smooth. However, when I try to change the scaling of the center point, rotation and see a then see A center point animation is instant and jerky, but smooth rotation / scaling is.

Here's my animation block: 

  [UIView animeaththithtion: 2.0 Animation: ^ {custom.view =frameframe = CGRectMake (self.containerSubview.frame.origin.x) , Self.contenterviewview.fr.origin.a, 200, 300); Self.containerSubview.alpha = 0.2; Self.customView.transform = CGAffineTransformConcat (CGFFEF Transmommentation (M_PI / 2), CGPhen Transformmaskel (1.5, 1.5)); Self.customView.center = self.containerSubview.center; } Closing: ^ (BOOL Finish) {NSLog (@ "Center Point:% @", NSStringFromCromoint (self.customView.center)); }];    
 
 
 I should read the document more carefully when it comes to conversion Since the changes are dependent on the center point of a scene, I can not do the animation simultaneously with a conversion at the UIVive level and modifying the center. Since the center has a dependency for change, it must be set up immediately and then the rest of the animation may be.  
 The solution was to animate on the layer of a scene using the group animation I was able to animate: center point, scaling and rotation.  
 The blog and the sample project is coming soon.
