Question

I have changed one of my instance methods to a class method so that it can be accessed from another class. The method is successfully called, but I have one warning on my code:

• Incomplete implementation (on the line ‘@implementation myViewController’)

My class code looks like this:

//...

@implementation myViewController

#pragma mark - myMethod
+ (void)myMethod:(CustomUIView *)customView didSelectText:(NSString *)text
{
    //...
}

//...

In my class header file, I have the following:

#import "CustomUIView.h"

//...

@interface myViewController : CustomUIViewController <CustomUIViewDelegate>
{
    //...
}

//...

@end

I imagine I must be declaring the method in the wrong part of the header file, possibly due to the clause? Or I’m missing something else altogether. I’ve had a good look around the net and as far as I can tell I’m following protocol; perhaps there’s something peculiar to my setup?

Edit: This is my protocol from my CustomUIView header file:

@class CustomUIView;

@protocol CustomUIViewDelegate <NSObject>

+ (void)myMethod:(CustomUIView *)customView didSelectText:(NSString *)text;
//...
@end

Your mistake is in the name of the method. Implementation is didSelectText and interface is didSelectTerm. (Text vs Term -> obviously should be the same) Also, you call [[self class] otherMethod:text]; as a class method, which, if you look closely, is not.
