編輯How to scale and rotate a view in a single animation

您可能需要使用核心動畫和組中添加兩個動畫：

CABasicAnimation *stetchAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale.x"]; 
stetchAnimation.toValue = [NSNumber numberWithDouble:(someView.frame.size.width+100)/someView.frame.size.width]; 

CABasicAnimation *skewAnimation = CABasicAnimation animationWithKeyPath:@"transform.rotation.x"]; 
stetchAnimation.toValue:[NSNumber numberWithInt:180]; 

//Add both animation at time when task is completed 

CAAnimationGroup *animationGroup = [CAAnimationGroup animation]; 
animationGroup.animations = [NSArray arrayWithObjects:stetchAnimation,skewAnimation,nil]; 
animationGroup.removedOnCompletion = YES; 
animationGroup.fillMode = kCAFillModeForwards; 
animationGroup.duration = 0.7; // increase duration if needed 

[someView.layer addAnimation:animationGroup forKey:@"animations"];

簡單的UIView動畫;暫時增長的觀點：

[UIView animateWithDuration:0.3 animations:^{ 
    CGRect frm = view.frame; 
    frm.size.width += 20; 
    frm.size.height += 20; 
    frm.origin.x -= 10; 
    frm.origin.y -= 10; 
    view.frame = frm; 
} completion:^{ 
    [UIView animateWithDuration:0.3 animations:^{ 
     CGRect frm = view.frame; 
     frm.size.width -= 20; 
     frm.size.height -= 20; 
     frm.origin.x += 10; 
     frm.origin.y += 10; 
     view.frame = frm; 
    }]; 
}];
