How to create a customized rounded UiView and UIBu

问题:

I want to create a similar UIView with rounded corner and UIButton just like this app. Can I implement this on Interface Builder?

回答1:

You can round the corners and set a border in code, just make sure you have QuartzCore framework included.

-(void) viewDidLoad {
    [super viewDidLoad];

    self.welcomeView.layer.cornerRadius = 5;
    self.welcomeView.layer.borderWidth = 2;
    self.welcomeView.layer.borderColor = [[UIColor whiteColor] CGColor];

}

Then just lay out your views and setup your outlets in IB. That should get you going, lots of cool stuff in Quartz.
