问题描述
我正试图将一些文字放在中心,但我似乎没有工作。
I'm trying to center some text but I it doesn't seem to be working.
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let title = UILabel()
title.text = "Some Sentence"
title.numberOfLines = 0
title.frame = CGRectMake(self.view.bounds.size.width/2,50,self.view.bounds.size.width, self.view.bounds.size.height) // x , y, width , height
title.textAlignment = .Center
title.sizeToFit()
title.backgroundColor = UIColor.redColor()
self.view.addSubview(title)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
这是我的代码使用,但这是我得到的:
That is the code that I'm using but this is what I get:
它不是屏幕的中心。有人能告诉我我做错了什么吗?
It's not center to the screen. Can someone tell me what am I doing wrong?
推荐答案
要使UILabel居中,只需添加此行
To center a UILabel just add this row
x和y:
title.center = self.view.center
x:
title.center.x = self.view.center.x
y:
title.center.y = self.view.center.y
