More "request for member in not a structure or union" errors

I'm using coocs2d and I get the title errors when commented. I imported UIKit into my header.

-(void)timerLoad:(NSTimer *)timer {
    timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0) target:self selector:@selector(timerLoad:) userInfo:nil repeats:YES];
    if (loadingBar.loading) { //error
        [activity stopAnimating];
    }
    else {
        [activity startAnimating];
    }
    if (loadingBar.loading = NO) { //error
        activity.HIDDEN = YES; //thanks ;)
    }
}

loadingBar is a CCProgressTimer and activity is a UIActiv开发者_C百科ityIndicatorView

Have you imported the CCProgressTimer.h header file into this implementation file? If all you do is a forward declaration (@class CCProgressTimer) then it tells the compiler that a class with that name exists, but it doesn't tell the compiler about the class' properties. You must have the header imported for dot syntax (loadingBar.loading) to make sense to the compiler.

(Also, UIView has a hidden property, not a visible property.)

try to forward declare your controller class in your view class's .h file

@class yourcontroller

@interface yourview....

hope it helps
