Question

I have added a category extension to my NSString class. The method basically formats the string a certain way. I have:

- (NSString *)formatStringAsColor {
    NSString *formattedString = [NSString stringWithFormat:(@"%@ color", self)];
    return formattedString;
}

Then I try calling this method elsewhere in my app but it says it cannot be found.

I try something like:
NSString *string = [myOtherString formatStringAsColor];

Any ideas?

Several errors in that code. Fixes below:

- (NSString*) formatStringAsColor {
                                                           v                 v
    NSString* formattedString = [NSString stringWithFormat: @"%@ color", self];
           v
    return formattedString;
}

Should work better now.
