在animateWithDuration调用时旋转

用下面的代码动画UIView,运行正常,就是不能实现在调用时实现旋转和缩放,我想同时实现这些,需要缩放至0,并且旋转。

[UIView animateWithDuration:0.4 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut
                 animations:^(void) {
                     recognizer.view.transform = CGAffineTransformMakeRotation(DegreesToRadians(540));
                     recognizer.view.backgroundColor = [[UIColor alloc] initWithRed:220.0/255.0 green:220.0/255.0 blue:220.0/255.0 alpha:1.0];   
                 }];

CGAffineTransformConcat方法:

[UIView animateWithDuration:0.4 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut
                 animations:^(void) {
                     recognizer.view.transform = CGAffineTransformConcat(CGAffineTransformMakeRotation(DegreesToRadians(540)), CGAffineTransformMakeScale(1.0, 1.0));
                     recognizer.view.backgroundColor = [[UIColor alloc] initWithRed:220.0/255.0 green:220.0/255.0 blue:220.0/255.0 alpha:1.0];   
                 }];

希望有帮助~
