Question

I’m trying to pass a value to a method in the delegate and return an NSString value. For some reason, i get a property not found on delegate error. I’d appreciate any help. Here is my code:

delegate.h

- (NSString*) getSoundFilePath:(int)pageNumber;

delegate.m

-(NSString*) getSoundFilePath:(int)pageNumber{
    switch (pageNumber) {
        case 1:
            return soundFilePathPage1;
            break;
        case 2:
            return soundFilePathPage2;
            break;
        case 3:
            return soundFilePathPage3;
            break;
        case 4:
            return soundFilePathPage4;
            break;
        case 5:
            return soundFilePathPage5;
            break;
        case 6:
            return soundFilePathPage6;
            break;
    }
    return nil;
}

app.m

int page = 1;
NSString *audioFilePath = appDelegate.getSoundFilePath:page; 
//that's where i get the error

Answer 1

You should look for an objective c introduction.

The correct line would be

NSString *audioFilePath = [appDelegate getSoundFilePath:page];
