我想在Swift中使數組定義標籤,但是當我嘗試這樣做並且運行該應用程序時,它們只是不顯示。我的視圖控制器代碼就在這裏:進口UIKit的Swift:標籤沒有顯示
class SmallPainViewController: UIViewController {
var tips = ["Play your favorite videogame", "Watch a movie", "Watch YouTube"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
for (i, tip) in tips.enumerate() {
let tipLabel = UILabel(frame: CGRectMake(CGFloat(i*50+150), 0, 30, 30))
tipLabel.center = CGPointMake(CGFloat(i*50+150), 0)
tipLabel.text = tip
tipLabel.textAlignment = NSTextAlignment.Center
self.view.addSubview(tipLabel)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
'tipLabel.center = CGPointMake(CGFloat的(我* 50 + 150),0)',爲什麼?你沒有足夠的設置框架?此外,你的意思是'tipLabel.center = CGPointMake(CGFloat(i * 50 + 150),15)' – Larme
