我的iOS动画01

1.嵌套使用，先变大再消失

[UIView animateWithDuration:1.25 aniamtions:^{

CGAffineTransform newTRansform = CGAffineTransformMakeScale(1.2, 1.2);

[firstImageView setTransform:newTransform];

[secondImageView setTransform:newTransform];

completion:^(BOOL finished){

[UIView animateWithDuration:1.2 animations:^{

[firstImageView setAlpha:0];

[secondImageView setAlpha:0];

}

completion:^(BOOL finished){

[firstImageView removeFromSuperview];

[secondImageView removeFromSuperview];

}

];

}

];

ios 怎么设置动画让一个view从底部弹出来：

首先设置一个VIEW初始位置在屏幕下, 比如iPhone6:CGRectMake(0, 667, 375, 667);

然后在一个方法中(比如button出发的方法)view添加动画

[UIView animateWithDuration:0.5 animations:^{

// 设置view弹出来的位置

self.myView.frame = CGRectMake(40, 100, 200, 250);

}];
