UIView 之 Animation 一边上跳 一边旋转

UIView *view = [[UIView alloc]initWithFrame:CGRectMake(100,100,100,100)];

view.backgroundColor = [UIColor redColor];

[self.view addSubview:view];

    

上跳：

[UIView beginAnimations:@""context:nil];

[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];

[UIView setAnimationDuration:0.7f];

[UIView setAnimationRepeatCount:30];

CGPoint center = view.center;

if (center.y >40.f) {

    center.y -=20;

    view.center = center;

}else{

    center.y +=20;

    view.center = center;

}

[UIView commitAnimations];

    

旋转：

for(int i =0; i <100; i++){

    [UIView beginAnimations:@"rotate"context:nil];

    [UIView setAnimationDuration:10];

    view.transform=CGAffineTransformMakeRotation((i+1)*2.0*M_PI/11.0);

    [UIView commitAnimations];

}
