Silence "potential leak warning" for create function?

  • Thread-topic: Silence "potential leak warning" for create function?

Given the following code (as an example):

- (CGImageRef)createImage

{

    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();

    

    CGContextRef context = CGBitmapContextCreate(NULL,

                                                 100,

                                                 100,

                                                 8, 

                                                 0,

                                                 colorSpace,

                                                 kCGBitmapByteOrder32Little | kCGImageAlphaNoneSkipFirst); 

    

    CGImageRef imageRef = CGBitmapContextCreateImage(context); 

    

    CGContextRelease(context);

    CGColorSpaceRelease(colorSpace);

    

    return imageRef;

}


- (void)someFunction

{

    CGImageRef image = [self createImage];

    

    CGImageRelease(image);

}



I get "Potential leak of an object" on "return imageRef;" and "Incorrect decrement of the reference count" on "CGImageRelease(image)".


How do I tell Xcode that "createImage" is a "create" function and that it's passing responsibility of releasing what is returned to the caller?
