How do I animate and resize a UIImageView? I tried doing this and it didn't work out for me:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
imgView.frame = CGRectMake(0, 0, 320, 480);
[UIView commitAnimations];
Try using a block animation:
[UIView animateWithDuration:1.0f // This can be changed.
animations:^{
CGRect frame = imageView.frame;
frame.size.width += 100.0f; // This is just for the width, but you can change the origin and the height as well.
imageView.frame = frame;
}
completion:^(BOOL finished){
}];
Hope that Helps!
Try this code. This works fine for me,
CGPoint newLogoutCenter = CGPointMake(160, 364);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0f];
twitterBarVIew.center = newLogoutCenter;
[UIView commitAnimations];
If we assume that you have correct reference to the imgView, then it seems that starting frame of the imgView is the same before and after animation.
Try to set imgView.frame to:
imgView.frame = CGRectMake(100,100,100,100);
//Set up the UIImageView. the Frame determines the position and size of the image. UIImageView *i = [[UIImageView alloc] initWithFrame:[CGRectMake(50.0,50.0,50.0,50.0)]];
//Add images to UIImageView i.images = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"1.png"],
[UIImage imageNamed:@"2.png"], nil];
//Set the amount of time for the animation to run i.animationDuration = 1.0f;
//start the animations [i startAnimating];
You can resize the image by changing the frame of the image
i.frame = CGRectMake(x, y, width, height);
