Xcode “AppDelegate *const __strong' to parameter of incompatible type” error

Question

When I declare appDelegate interface as follows in order to set NSXMLParserDelegate, I receive some warnings from other views that are using [[UIApplic

Answer 1

You really should not be making your AppDelegate publicly exposing interfaces. It creates very tight coupling between all your code. If other code (outside your AppDelegate) is needing an NSXMLParserDelegate you should make a different class for it.

It looks like your AppDelegate is needing to be a delegate for its own purposes. You can "privately" implement the interface by making a class extension in your AppDelegate.m file.

@interface AppDelegate() 
@end

Doing the above will remove the warning you received here:

[xmlParser setDelegate:self];
