UIAlertController的建立以及添加,uialertcontroller
個人還是更喜歡以前的UIAlertView的建立方法,更新後的UIAlertController雖然說將UIAlertView和UIActionSheet的功能和作用以一種模組化替換的方式來代替,但是卻給人一種多此一舉的感覺,原先一步到位變成了現在就連一個取消或者“OK”按鈕都需要通過Add來添加才能實現,說是畫蛇添足也不為過。
import UIKit
class ViewController: UIViewController {
var tapfun: UIButton!
override func viewDidLoad() {
self.tapfun = UIButton()
self.tapfun.frame = CGRectMake(50, 270, 200, 200)
self.tapfun.backgroundColor = UIColor.redColor()
self.tapfun.addTarget(self, action: "alert", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(self.tapfun)
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func alert(){
let alertView = UIAlertController(title: "123", message: "222", preferredStyle: UIAlertControllerStyle.Alert)
alertView.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alertView, animated: true, completion: nil)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
