Create multiple UIImageViews programmatically - ios

Question

I want to create multiple UIImageViews programmatically with different tags and add them as subview of my main view.
I have a property of my UIImageView in header:
#property (strong, nonatomic) UIImageView *grassImage;
then i'm trying to create multiple views:
for (int i=0;i<13;i++){
grassImage = [[UIImageView alloc] init];
int randNum = arc4random() % 320; //create random number for x position.
[grassImage setFrame:CGRectMake(randNum, 200.0, 50.0, 25.0)];
[grassImage setTag:i+100];
[grassImage setImage:[UIImage imageNamed:#"grass"]];
[self.view addSubview:grassImage];
}
But when I'm trying to access this image views using tag, I'm getting only last tag - 112.
My question - how I can access this views correctly, using their tag?

Answer 1

You are only getting the last one because you are recreating the same view all the time.
Get rid of that variable, and add your views like this:
for (int i=0;i<13;i++){
UIImageView *grassImage = [[UIImageView alloc] init];
int randNum = arc4random() % 320; //create random number for x position.
[grassImage setFrame:CGRectMake(randNum, 200.0, 50.0, 25.0)];
[grassImage setTag:i+100];
[grassImage setImage:[UIImage imageNamed:#"grass"]];
[self.view addSubview:grassImage];
}
And to get the views:
UIImageView *imgView = [self.view viewWithTag:110];

Answer 2

Since you are re-creating the same image again and again, if you access grassImage it will give you the last imageview you created. Instead you can get the imageview like this.
for (UIImageView *imgView in self.view.subviews) {
if ([imgView isKindOfClass:[UIImageView class]]) {
NSLog(#"imageview with tag %d found", imgView.tag);
}
}

Use this code for getting subview with a particular tag,
UIImageView *imgViewRef = (UIImageView *)[self.view viewWithTag:TAG_NUMBER];
