top, right, and bottom
I am a label |
myLabel.layer.borderWidth = 1;
myLabel.layer.borderColor = [UIColor blackColor];
You can use a mask. This is the code I used to test the theory, and it works well:
// Define the border width in a variable, we'll be using it elsewhere CGFloat borderWidth = 1.0; // This creates a testing view to test the theory, in your case this will be your UILabel UIView* view = [[UIView alloc] initWithFrame:CGRectMake(20, 60, 250, 100)]; view.layer.borderColor = [UIColor blackColor].CGColor; view.layer.borderWidth = borderWidth; [self.view addSubview:view]; // Create the mask to cover the area of the view you want to **show** // Here, we create a mask that covers most of the view, except the left edge // The mask needs to be coloured in black, as black acts as transparent, whereas white is opaque in mask parlance UIView* mask = [[UIView alloc] initWithFrame:CGRectMake(borderWidth, 0, view.frame.size.width - borderWidth, view.frame.size.height)]; mask.backgroundColor = [UIColor blackColor]; view.layer.mask = mask.layer;
You can adjust the size and position of the mask (given the borderWidth) to show/hide the border edges you're interested in. The example above hides the left edge.
