objective-c - How Do I Access IBOutlets From Other Classes in Objective-C?

Question

How do I access IBOutlets that have been created in another class? For example, if I have an IBOutlet in Class A how can I access in Class B? If I can not access IBOutlets from other classes what is a work-around?

Answer 1

You'll need to make your IBOutlet a @property and define a getter for that property via @synthesize or you can define your own getter, here's an example of the former:

@interface ClassA : NSObject {
   UIView *someView;
}
@property (nonatomic, retain) IBOutlet UIView *someView;
@end

@implementation ClassA

@synthesize someView;

...

@end

Then, in ClassB, you can do this:

@implementation ClassB 

- (void) doSomethingWithSomeView {
   ClassA *a = [ClassA new];
   UIView *someView = [a someView];
   //do something with someView...
}

...

@end
