IOS: remove imageView - ios

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?

Answer 1

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];
}

Answer 2

Just call removeFromSuperview for every subView. Something like:
for(UIView *subview in self.view.subviews)
[subview removeFromSuperview];

Answer 3

NSMutableArray *images = [NSMutableArray array];
for Contact *contact in myArray){
if(...){
UIImageView *fix = [[UIImageView alloc] initWithImage:myImage];
[self.view addSubview:fix];
[fix setFrame:[contact square]];
[images addObject:fix];
}
}
for (UIView *v in images){
[v removeFromSuperview];
}
Another approach
for(UIView *v in self.view.subviews)
if([v isKindOfClass:[UIImageView class]])
[v removeFromSuperview];
I put an example together.
