Question

I’m not exactly sure how to check whether a NSString is blank or not, I’ve got this code…

 NSString *imageName = [myItem objectForKey:@"iconName"];

        if(imageName == @"")
        {
        }

And when I do a print on the myItem object, it comes up as..

iconName = "";

At the NSString *imageName line, I noticed in xcode in the console it says

“variable is not NSString”

Which I don’t get as iconName is saved and stored on the parse.com database as a NSString.

When I run that code though it doesn’t seem to realise that imageName = “”;

You should use this code block when comparing strings:

if ([imageName isEqualToString:@""]){
}
