error: @synthesize

Question

In my AppDelegate.h file i written the following code

@interface iBountyHunterAppDelegate : NSObject <UIApplicationDelegate> {
    UITabBarController *tabcontroller;

}
@property (nonatomic,retain) IBOutlet UITabBarController *tabcontroller;

and in AppDelegate.h file I synthesize it.

@synthesize tabcontroller;

but in @synthesize line i get an error and the msg is: "MISSING CONTEXT FOR PROPERTY IMPLEMENTATION DECLARATION"

can anyone tell me how to solve it?

Answer 1

I suspect you have put the @synthesize outside of your @implementation. It should look something like this

//  iBountyHunterAppDelegate.m

#import "iBountyHunterAppDelegate.h"

@implementation iBountyHunterAppDelegate

@synthesize tabcontroller; // note that this is between @implementation and @end

// other stuff

@end

Answer 2

"and in AppDelegate.h file I synthesize it." Probably it´s just misspelled but it has to be in .m file :P

Answer 3

@interface iBountyHunterAppDelegate : NSObject <UIApplicationDelegate> 

{

    UITabBarController IBOutlet *tabcontroller;

}

@property (nonatomic,retain) IBOutlet UITabBarController *tabcontroller;

and in AppDelegate.h file I synthesize it.

@synthesize tabcontroller;

Answer 4

在controller（iBountyHunterAppDelegate.m）文件而不是接口（.h）文件中合成您的属性
