How to identify animations completed or not? [closed]

问题

I am trying to find out whether my animation runs and completed or else it is still in process??

animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320 , 480)];
animationImageView.animationImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"eg1"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg1"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg1"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"], nil];
animationImageView.animationDuration = 2.2f;
animationImageView.animationRepeatCount=1;
[self.view addSubview:animationImageView];
[animationImageView startAnimating];

Can anyone help me?

I am having UIview over a container which holds UITableviewcontroller, i given segue to my view controller from navigation controller. Now i would like to run my UIView with navigation bar hidden. I tried with code but it is in vain either both views having navigation bar or both does not have.

I am working with storyboard.

Actually am using UIImageView for "Splashscreen" purpose.

回答1:

try this

[UIView animateWithDuration:2.2f animations:^{

    UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320 , 480)];
    animationImageView.animationImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"eg1"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg1"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg1"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"],[UIImage imageNamed:@"eg2"], nil];
    animationImageView.animationDuration = 2.2f;
    animationImageView.animationRepeatCount=1;
    [self.view addSubview:animationImageView];
    [animationImageView startAnimating];

} completion:^(BOOL finished) {
    NSLog(@"Finished");
}];

To find out animating or not

    if ([YourAnimationImageView isAnimating]) {

        NSLog(@"Yes animation in progress");
    }
    else{
        NSLog(@"NO. animation has been stopped/finished");
    }
