2) i want to Add these 3 Images at 3 different locations animatedly, means add one by one images animatedly with some duration??

推荐答案

根据您的要求，您想要一张一张的动画

As per your requirement you want to animate image one by one

为此目的使用第一个图像动画的完成块来动画第二个图像等等

for that purpose use completion block of first image animation to animate second image and so on like below code

UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"-t%d",1]]];
[imgView setBackgroundColor:[UIColor redColor]];

UIImageView *imgView2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"-t%d",2]]];
[imgView2 setBackgroundColor:[UIColor redColor]];

UIImageView *imgView3 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"-t%d",2]]];
[imgView3 setBackgroundColor:[UIColor redColor]];

[self.view addSubview:imgView];
[self.view addSubview:imgView2];
[self.view addSubview:imgView3];

[UIView animateWithDuration:0.5 delay:1.0 options:UIViewAnimationOptionLayoutSubviews animations:^{

    [imgView setFrame:CGRectMake(0, 0, 150, 150)];


} completion:^(BOOL finished) {

    [UIView animateWithDuration:0.5 delay:1.0 options:UIViewAnimationOptionLayoutSubviews animations:^{
        [imgView2 setFrame:CGRectMake(self.view.frame.size.width - 150, 0, 150, 150)];

    } completion:^(BOOL finished) {

        [UIView animateWithDuration:0.5 delay:1.0 options:UIViewAnimationOptionLayoutSubviews animations:^{
            [imgView3 setFrame:CGRectMake(0, self.view.frame.size.height - 150, 150, 150)];

        } completion:^(BOOL finished) {


        }];

    }];

}];
