This line is the same as
id item;
if ([arr count] > 0) {
item = arr[0];
}else{
item = nil;
}
Frage
Please forgive the title, it's probably wrong, since I don't know anything about it. Because of that, I didn't have any search terms to look it up, so could someone explain me what does this mean and how to use it? I just picked this example as I recently found it.
id item = [arr count] > 0 ? arr[0] : nil;
