Question

I need to send a different udid to my database for few testing purpose. Since [UIDevice currentDevice] uniqueIdentifier] is called in almost 15 places it will be very difficult for me to make a code change and then test. Is there a way to override that method for a while and send a another number as udid ?

Answer 1

You should be able to override it in a category on UIDevice. Create a header like this:

@interface UIDevice (overrideId)

@property (nonatomic,readonly,retain) NSString *uniqueIdentifier

@end

And then a .m like this:

@implementation UIDevice (overrideId)

- (NSString *)uniqueIdentifier {
    return @"whatever";
}

@end

Don’t forget to remove it again before releasing.
