iOS - check if image is present in app bundle

Question

How can I tell if an image is present in the main app bundle based on a string? For example, is there an image called image1.png in the bundle?

NSBundle method:

- (NSString *)pathForResource:(NSString *)name ofType:(NSString *)extension

will return nil if no image was found.

i.e.

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"image1" ofType@"png"];
if(filePath.length > 0 && filePath != (id)[NSNull null]) {
   UIImage *myImage = [UIImage imageWithContentsOfFile:filePath];
}

Thanks. How do I get the image if I find it, since that method just returns a string? – soleil Sep 12 '12 at 18:38
[UIImage imageWithContentOfFile:yourFilePath]; – J2theC Sep 12 '12 at 18:44
The second comparison in the if statement is incorrect. Nil is not the same thing as [NSNull null], so the comparison doesn't make sense. – Anton Sep 12 '12 at 21:32
