Hello,
I'm using an NSArray of images, and each image has a tag. I want to know how to retrieve these images from the array using their tags.
Any input would be appreciated. Thanks.

A:
- (UIImage *)imageFromArray:(NSArray *)array withTag:(NSInteger)tag {
for (UIImage *image in array) {
if ([image tag] == tag)
return image;
}
return nil;
}
Completely untested, though.

`UIImage` does not have a `tag` property or method. `UIImageView` does. Unfortunately, the question is not specific enough.

The OP didn't say the the image objects were UIImages or UIImageViews. But a subclass of UIImage with an added tag property might work using the above code.
