IOS笔记之UIKit_UIAlertView、UIActionSheet

//首先必须继承协议

@interface TRViewController : UIViewController<UIAlertViewDelegate,UIActionSheetDelegate>

//UIAlertView功能实现

- (IBAction)clicked:(id)sender {

UIButton *btn = sender;

//设置tag值

if (btn.tag==0) {

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Title" message:@"message" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

// 设置AlertView样式

[alertView setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];

//把alertView里面的TF取出来

UITextField *nameTF = [alertView textFieldAtIndex:0];

UITextField *pwTF = [alertView textFieldAtIndex:1];

nameTF.text = @"haha";

pwTF.text = @"adfadsf";

//弹窗显示

[alertView show];

}else{

//UIActionSheet初始化

UIActionSheet *as = [[UIActionSheet alloc]initWithTitle:@"Title" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"destructive" otherButtonTitles:@"呵呵", nil];

[as showInView:self.view];

}

}

//AlertView点击事件

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

NSLog(@"%ld",(long)buttonIndex);

//第一个按钮

if (buttonIndex==1) {//确定

UITextField *nameTF = [alertView textFieldAtIndex:0];

UITextField *pwTF = [alertView textFieldAtIndex:1];

NSLog(@"%@  %@",nameTF.text,pwTF.text);

}else{//取消

}

}

//ActionSheet点击事件

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{

NSLog(@"%ld",(long)buttonIndex);

}
