I am using a function in a class as below
- (void) uploadMorePic:(NSDictionary *) MuliPics: (NSData *)file
It shows the warning - Muli
It's a poor message, but it's because you didn't provide a name for the first parameter to your method. Try this:
-(void)uploadMorePic:(NSDictionary *)dict muliPics:(NSData *)file
I also fixed a style issue; the name of the second part of the method name should start with a lower-case letter. I don't know what your method does, so you may be able to come up with a better name.
