    UIViewAnimationOptionAllowUserInteraction      = 1 <<  1, // 允许视图在播放动画的时候 依旧触发事件
    UIViewAnimationOptionBeginFromCurrentState     = 1 <<  2, // 从当前状态开始动画
    UIViewAnimationOptionRepeat                    = 1 <<  3, // 重复执行动画
    UIViewAnimationOptionAutoreverse               = 1 <<  4, // 执行动画回路

1:View改变大小和位置

CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:nil context:context];
[UIView setAnimationDuration:0.4];
[UIView setAnimationDelegate:self];
self.frame =CGRectMake(0,self.frame.size.height-44,self.frame.size.width,44);
[UIView commitAnimations];

2:改变View的自身大小

CGAffineTransform tr = CGAffineTransformScale(self.transform, 0.55, 0.55); 
[UIView animateWithDuration:0.1 delay:0 options:0 animations:^{ 
        self.transform = tr;
} completion:^(BOOL finished) {}];

CGPoint fromPoint = CGPointMake(0, 0);
UIBezierPath *movePath = [UIBezierPath bezierPath];
[movePath moveToPoint:fromPoint];
CGPoint toPoint = CGPointMake(300, 460);
[movePath addQuadCurveToPoint:toPoint
                     controlPoint:CGPointMake(toPoint.x,fromPoint.y)];//弧线
    
 CAKeyframeAnimation *moveAnim = [CAKeyframeAnimation animationWithKeyPath:@"position"];
 moveAnim.path = movePath.CGPath;
 moveAnim.removedOnCompletion = NO;
 moveAnim.duration = 2;
 [moveAnim setRepeatCount:2];
 [self.view1.layer addAnimation:moveAnim forKey:nil];

4: View 旋转180度

CGAffineTransformRotate(self.colTypeImageView.transform, 3.14 )

5:View 左右抖动动画

- (void) shakeAnimationWithControl:(UIView *)view {
    CAKeyframeAnimation *keyAn = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    [keyAn setDuration:0.5f];
    NSArray *array = [[NSArray alloc] initWithObjects:
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x-5, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x+5, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x-5, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x+5, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x-5, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x+5, view.center.y)],
                      [NSValue valueWithCGPoint:CGPointMake(view.center.x, view.center.y)],
                      nil];
    [keyAn setValues:array];
    NSArray *times = [[NSArray alloc] initWithObjects:
                      [NSNumber numberWithFloat:0.1f],
                      [NSNumber numberWithFloat:0.2f],
                      [NSNumber numberWithFloat:0.3f],
                      [NSNumber numberWithFloat:0.4f],
                      [NSNumber numberWithFloat:0.5f],
                      [NSNumber numberWithFloat:0.6f],
                      [NSNumber numberWithFloat:0.7f],
                      [NSNumber numberWithFloat:0.8f],
                      [NSNumber numberWithFloat:0.9f],
                      [NSNumber numberWithFloat:1.0f],
                      nil];
    [keyAn setKeyTimes:times];
    [view.layer addAnimation:keyAn forKey:@"TextAnim"];
}

6:切换ViewController或者将应用切换至后台时,动画不停止的方法

 shake.removedOnCompletion = NO;

7:使用CAAnimation播放动画完后希望能适应新的坐标变化

[button.layer addAnimation:animationgroup forKey:@"Expand"];
button.center = CGPointMake(button.center.x, button.center.y);
