1.UIAlertVIew以-(void)show的方法显示:
- (void)viewDidLoad { [super viewDidLoad]; //UIAlertView的使用 [self showAlert]; //UIAcyionSheet使用 // [self showAction]; #pragma mark [self showAlertController];方法不可以放在此处因为UIAlertControl继承与UIViewController //UIAlertControl的使用 // [self showAlertController]; }
UIAlertView 的实现:
-(void)showAlert{ UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"紧急通知" message:@"由于幸福指数哦不断下降,经调查和假期成线性关系,特批以后工作一天休息一天" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil]; alertView.alertViewStyle = UIAlertViewStyleDefault; /* UIAlertViewStyleDefault ,默认 UIAlertViewStyleSecureTextInput, 密码输入框 UIAlertViewStylePlainTextInput, 文本输入框 UIAlertViewStyleLoginAndPasswordInput 用户及密码 */ [alertView show]; } #pragma mark - UIALertDelegate -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ switch (buttonIndex) { case 0: NSLog(@"点击%ld",buttonIndex); break; case 1: NSLog(@"点击%ld",buttonIndex); break; default: break; } }
2.UIActionSheet的使用
-(void)showAction{ UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:@"请假\n选择请假类型" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"事假" otherButtonTitles:@"病假",@"产假", nil]; [actionSheet showInView:self.view]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #pragma mark UIActionSheetDelegate -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{ switch (buttonIndex) { case 0: NSLog(@"点击%ld",buttonIndex); break; case 1: NSLog(@"点击%ld",buttonIndex); break; case 2: NSLog(@"点击%ld",buttonIndex); break; default: break; } }
3.UIAlertControl的简单使用
-(void)showAlertController{ //UIAlertControllerStyle两种类型UIAlertControllerStyleAlert类似UIAlertView //UIAlertControllerStyleActionSheet类似UIActionSheet UIAlertController *alertControl = [UIAlertController alertControllerWithTitle:@"you and me" message:@"together forever" preferredStyle:UIAlertControllerStyleAlert]; //block代码块取代了delegate UIAlertAction *actionOne = [UIAlertAction actionWithTitle:@"No matter of life and death" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action) { NSLog(@"生死相依"); }]; UIAlertAction *alertTwo = [UIAlertAction actionWithTitle:@"Share weal and woe" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { NSLog(@"同甘共苦"); }]; UIAlertAction *alertthree = [UIAlertAction actionWithTitle:@"Sure" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) { NSLog(@"确定"); }]; [alertControl addAction:actionOne]; [alertControl addAction:alertTwo]; [alertControl addAction:alertthree]; //UIAlertControllerStyle类型为UIAlertControllerStyleAlert可以添加addTextFieldWithConfigurationHandler:^(UITextField *textField) [alertControl addTextFieldWithConfigurationHandler:^(UITextField *textField) { textField.text = @"for love "; }]; [self presentViewController:alertControl animated:YES completion:nil]; }
