I have the following method in UIImageManipulation.m:
+(UIImage *)scaleImage:(UIImage *)source toSize:(CGSize)size
{
UIImage *scaledImage = nil;
if (source != nil)
{
UIGraphicsBeginImageContext(size);
[source drawInRect:CGRectMake(0, 0, size.width, size.height)];
scaledImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
}
return scaledImage;
}
I am calling it in a different view with:
imageFromFile = [UIImageManipulator scaleImage:imageFromFile toSize:imageView.frame.size];
(imageView is a UIImageView allocated earlier)
This is working great in my code. I resizes the image perfectly, and throws zero errors. I also don't have anything pop up under build - analyze. But the second I turn on NSZombieEnabled to debug a different EXC_BAD_ACCESS issue, the code breaks. Every single time. I can turn NSZombieEnabled off, code runs great. I turn it on, and boom. Broken. I comment out the call, and it works again. Every single time, it gives me an error in the console: -[UIImage release]: message sent to deallocated instance 0x3b1d600. This error doesn't appear if `NSZombieEnabled is turned off.
Any ideas?
--EDIT--
Ok, This is killing me. I have stuck breakpoints everywhere I can, and I still cannot get a hold of this thing. Here is the full code when I call the scaleImage method:
-(void)setupImageButton
{
UIImage *imageFromFile;
if (object.imageAttribute == nil) {
imageFromFile = [UIImage imageNamed:@"no-image.png"];
} else {
imageFromFile = object.imageAttribute;
}
UIImage *scaledImage = [UIImageManipulator scaleImage:imageFromFile toSize:imageButton.frame.size];
UIImage *roundedImage = [UIImageManipulator makeRoundCornerImage:scaledImage :10 :10 withBorder:YES];
[imageButton setBackgroundImage:roundedImage forState:UIControlStateNormal];
}
The other UIImageManipulator method (makeRoundCornerImage) shouldn't be causing the error, but just in case I'm overlooking something, I threw the entire file up on github here.
It's something about this method though. Has to be. If I comment it out, it works great. If I leave it in, Error. But it doesn't throw errors with NSZombieEnabled turned off ever.
