Data type for removeFromSuperview

[Rifts]

Hey again,

This may sound weird but I am trying to do this


for (int x = 1; x < randomNumber; x++) {

NSString *result = [NSString stringWithFormat:@"image%d", x];
NSLog(@"%@", result);
[result removeFromSubview]; //getting NSString may not respond to 'removeFromSubview'
}

this is listing all of the images I have added to my view. I'm trying to remove them by name using this but I can not use an NSString so what data type can I convert this to in order to use

[result removeFromSubview];

?

I hope that makes sense, the reason I am doing it this way is because there is a random number of images added so I never know how many to remove.

Strings aren't views. Only a view can be a subview of some other view. Since you are working with images, your subviews are most likely UIImageViews. You need a reference to those imageviews and then send them the removeFromSuperview message.

Hey I actually figured it out doing this



for (int x = 1; x < randomNumber; x++) {

UIImageView *image = (UIImageView *)[self.view viewWithTag:x];
[image removeFromSuperview];
}


just had to add tags to the images and using that code works great!

thanks for the info

That can work too, just make sure you don't use those tags for anything else in the UI or you'll end up removing parts you don't want to remove.

Also, please use [code] tags when posting code, it makes it much easier to read.

they are the only tags im using, the app is pretty simple. Sorry I will from now on.
