Question

I have this code:

for(Contact *contact in myArray){
        if(...){
            UIImageView *fix = [[UIImageView alloc] initWithImage:myImage];
            [self.view addSubview:fix];
            [fix setFrame:[contact square]];
            return;
        }
    }

in this code I add an imageView on self.view but in my app i call this “for” many times and finally I have my self.view with 4 or 5 imageView “fix”.
What’s the way to remove all these imageView from my self.view?

If you only want to remove instances of UIImageView, you can try something like this:

for (UIView *v in self.view.subviews) {
    if ([v isKindOfClass:[UIImageView class]]) {
        [v removeFromSuperview];
    }
}

Update:

As vikingosegundo wrote in the comments, you can do this instad.

If you add each imageview to an array, you can remove them from the view later on like this:

NSMutableArray *images = [[NSMutableArray alloc] init];

for Contact *contact in myArray){
    if(...){
        UIImageView *fix = [[UIImageView alloc] initWithImage:myImage];
        [self.view addSubview:fix];
        [fix setFrame:[contact square]];
        [images addObject:fix]; // Add the image to the array.
        return;
    }
}

The later on, remove them from the view:

for (UIImageView *v in images) {
    [v removeFromSuperview];
}
