Question

I have two UINavigationController in the appdelegate.h

{
    UINavigationController *leftView;  
    UINavigationController *rightView;
    UIWindow *window;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UINavigationController *leftView;
@property (nonatomic, retain) IBOutlet UINavigationController *rightView;

appdelegate.m

@synthesize leftView;
@synthesize rightView;

then in a different class

test.m

#import "appdelegate.h"  

if I do:

[self leftView] pushViewController...; //(Everything is ok)

but if I change it to:

[self rightView] pushViewControll...; //it complains about ViewController may not respond to -rightView

Answer 1

You code seems right; what doesn’t seem right is that you’re including AppDelegate. If the code was in AppDelegate.m, it would probably work without any complaints by the compiler.

Instead, you’ve defined @property lines for each, but that is in AppDelegate.h, not test.h – but you’re using them in test.m. That is probably the source of the problem.

Interestingly, does the code actually run?
