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);
}
