Three, UIView call code block:

1、layer的CATransform3DIdentity;

romate.layer.transform = CATransform3DIdentity;

  [UIView animateWithDuration:20

                        delay:0

                      options:UIViewAnimationOptionAllowUserInteraction|

   UIViewAnimationOptionCurveLinear

                   animations:^{

                     romate.layer.transform = CATransform3DMakeRotation(M_PI/4, 0, 0, 1);

                   }

                   completion:NULL

   ];

2、view的CGAffineTransformIdentity；

 romate.transform = CGAffineTransformIdentity;

[UIView animateWithDuration:100

                        delay:0

                      options:UIViewAnimationOptionAllowUserInteraction|

   UIViewAnimationOptionCurveLinear

                   animations:^{

                     romate.transform = CGAffineTransformMakeRotation(M_PI);

 

                   }

                   completion:NULL

   ];
