I have 10 UIImageViews which do the same thing (they have some void methods that change their image with a timer). My UIImageView is an outlet and I want to connect all the 10 imageViews to the same outlet, but interface builder doesn't allow me.
I found that there is a solution, IBOutletCollection. Can anyone explain to me how to use this to connect multiple imageViews to the same outlet?
Declare a property to hold your imageView's and then hook them up in interface builder like normal
@property (nonatomic, strong) IBOutletCollection(UIImageView) NSArray *imageViews;
it's just a normal NSArray
but when the nib is loaded it will be populated with your imageView's
Update
In the header file for you view controller which has the multiple imageView's on you need to add the property above - it may look something like this:
@interface MyViewController : UIViewController
@property (nonatomic, strong) IBOutletCollection(UIImageView) NSArray *imageViews;
// other properties
@end
Now in the interface builder you connect all the imageView's to this one property.
Now I just work with the imageViews
collection
for (UIImageView *imageView in self.imageViews) {
imageView.image = someImage;
}
