OC与Swift写AlertController
在iOS8以后,alertView和actionSheet,被 alertController所替代.今天用OC和swift,分别写了alertController.给大家做个参考.共勉.
OC:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIButton * btn = [UIButton buttonWithType:UIButtonTypeSystem];
btn.frame = CGRectMake(100, 100, 100, 40);
btn.backgroundColor = [UIColor yellowColor];
[btn addTarget:self action:@selector(aa) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
- (void)aa
{
NSLog(@"%f",[[[UIDevice currentDevice] systemVersion] floatValue]);
UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"报警" message:@"这是IOS8以后的报警" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction * alertAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action) {
NSLog(@"11111");
}];
[alertController addAction:alertAction];
[self presentViewController:alertController animated:YES completion:nil];
}
?
Swift:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let btn:UIButton = UIButton.buttonWithType(UIButtonType.System) as UIButton;
btn.backgroundColor = UIColor.yellowColor();
btn.frame = CGRectMake(100, 100, 100, 40);
btn.addTarget(self, action: "aa", forControlEvents: UIControlEvents.TouchUpInside);
self.view.addSubview(btn);
}
?
func aa(){
var alertController:UIAlertController = UIAlertController(title: "报警", message: "ios和Swifit", preferredStyle: UIAlertControllerStyle.Alert);
var alertAction:UIAlertAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil);
alertController.addAction(alertAction);
self.presentViewController(alertController, animated: true, completion: nil);
}
