Swift:标签未显示
Swift: Labels not showing up
我正在尝试制作由 Swift 中的数组定义的标签,但是当我尝试这样做并且我 运行 应用程序时,它们就是不显示。我的视图控制器代码是正确的 here:import UIKit
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.
}
}
尝试使用:
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.enumerated() {
let tipLabel = UILabel(frame: CGRect(x: (i*50+150), y: 150, width: 30, height: 30))//CGRect(CGFloat(i*50+150), 0, 30, 30)
tipLabel.center = CGPoint(x: (i*50+150), y: 150) //CGPoint(CGFloat(i*50+150), 0)
tipLabel.text = tip
tipLabel.textAlignment = NSTextAlignment.center
self.view.addSubview(tipLabel)
}
}
我认为您使用的是 swift 2.0
