Question

Why that if condition, comparing two datetime, doens’t work?
If they need to be NSDate, how can I convert them?

Code:

if ([[NSDate date] dateStringFromFormat:@"dd/MM/yyyy HH:mm"] > [self.tfDatetime dateStringFromFormat:@"dd/MM/yyyy HH:mm"]) {
    // Do ...something
}

Answer 1

To compare two NSDates(say, dateOne and dateTwo), use this

switch ([dateOne compare:dateTwo]){
     case NSOrderedAscending:
          NSLog(@"NSOrderedAscending");
    break;
    case NSOrderedSame:
          NSLog(@"NSOrderedSame");
    break;
    case NSOrderedDescending:
         NSLog(@"NSOrderedDescending");
    break;
}
