Let’s assume two dates: NSDate *date1; NSDate *date2; Then the following comparison will tell which is earlier/later/same: if ([date1 compare:date2] == NSOrderedDescending) { NSLog(@”date1 is later than date2″); } else if ([date1 compare:date2] == NSOrderedAscending) { NSLog(@”date1 is earlier than date2″); } else { NSLog(@”dates are the same”); } Please refer to the NSDate class … Read more

Click on your project, and check that this file is not present in the tab Build Phases. Normally no header files should stay here. Clean and build it again, it should work!
It’s possible in iOS 6 and later: You have to implement the method – (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender In your view controller. You do your validation there, and if it’s OK then return YES; if it’s not then return NO; and the prepareForSegue is not called. Note that this method doesn’t get called automatically when triggering … Read more
Despite the “Unknown class MyClass in Interface Builder file.” error printed at runtime, this issue has nothing to do with Interface Builder, but rather with the linker, which is not linking a class because no code uses it directly. When the .nib data (compiled from the .xib) is loaded at runtime, MyClass is referenced using … Read more

in viewDidLoad, add this line: self.tableView.separatorColor = [UIColor clearColor]; and in cellForRowAtIndexPath: for iOS lower versions if(indexPath.row != self.newCarArray.count-1){ UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 2)]; line.backgroundColor = [UIColor redColor]; [cell addSubview:line]; } for iOS 7 upper versions (including iOS 8) if (indexPath.row == self.newCarArray.count-1) { cell.separatorInset = UIEdgeInsetsMake(0.f, cell.bounds.size.width, 0.f, 0.f); }
You need to use view’s layer to set border property. e.g: #import <QuartzCore/QuartzCore.h> … view.layer.borderColor = [UIColor redColor].CGColor; view.layer.borderWidth = 3.0f; You also need to link with QuartzCore.framework to access this functionality.
You can do it like this: label.font = UIFont(name: label.font.fontName, size: 20) Or like this: label.font = label.font.withSize(20) This will use the same font. 20 can be whatever size you want of course. Note: The latter option will overwrite the current font weight to regular so if you want to preserve the font weight use … Read more
