Warning-used as the name of the previous parameter rather than as part of the selector

I am using a function in a class as below

- (void) uploadMorePic:(NSDictionary *) MuliPics: (NSData *)file  

It shows the warning - Muli

Answer 1

@dpassage 's answer is nice。

The function name of objective-c is not like C or C++， it has some parameter and the same num of description of parameter name。 In your case， you did not set your first parameter name or you did not set your description of your second parameter name.

What @dpassage said was the first condition, missing first parameter name.
