Thread 1: signal SIGABRT in main.m file

Question

I need some help in Xcode. I am getting the error Thread 1: SIGABRT and it is pointing to the main.m file. I set up the exception breakpoint and it still stops in the main.m file.

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

#import "AppDelegate.h"

int main(int argc, char *argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

That is the code that I have in my main.m file. Can someone please help me with this error.

The full error is:

In my game.m file I have:

    CFTimeInterval timeSincePause = [layer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime;
    layer.beginTime = timeSincePause;
}


- (IBAction)pause:(id)sender {
    [self pauseLayer:self.view.layer];

}

- (IBAction)resume:(id)sender {
    [self resumeLayer:self.view.layer];
}

In my game.h file I have:

- (IBAction)pause:(id)sender;
- (IBAction)resume:(id)sender;


-(void)pauseLayer:(CALayer*)layer;
-(void)resumeLayer:(CALayer*)layer;

I need some help.

Answer 1

-[game pause:]: unrecognized selector sent to instance 0x845ece0

This means that you have an instance of the game class (which, btw, that class should be Game, not game, classes are capitalized) and something is calling the method pause: on that class, but there is no pause: method.

Given that the class is called Game (fixed) and pausing seems like a reasonable thing to do to a game, it is unlikely that this is an over-release problem. pause: seems like it is something that you might have a button hooked up to in interface builder.

Did you, perchance, rename the pause: method to something else (pauseGame:?) and not fix the connection in IB?

---

And that pause: implementation is inside the @implementation Game scope? If so, trying cleaning the project and rebuilding as there may be a dependency issue. If not, then that is your problem.

If the build from clean thing doesn't work, then there is some detail missing. Since building from clean didn't work, you'll have to post more details. Show the declaration of the class, at least.
