IPhone之自定义弹出窗口

初始化代码：

 

if (!_alertView) { _alertView = [[UIAlertView alloc] initWithTitle:title message:@"\n\n\n" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"登录", nil]; _alertView.delegate = self; usernameField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 50.0, 260.0, 25.0)]; usernameField.delegate = self; usernameField.placeholder = @"用户名"; usernameField.autocapitalizationType = UITextAutocapitalizationTypeNone; usernameField.autocorrectionType = UITextAutocorrectionTypeNo; usernameField.returnKeyType = UIReturnKeyNext; usernameField.keyboardType = UIKeyboardTypeEmailAddress; [usernameField setBackgroundColor:[UIColor whiteColor]]; [_alertView addSubview:usernameField]; passwordField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 85.0, 260.0, 25.0)]; passwordField.delegate = self; passwordField.placeholder = @"密码"; passwordField.secureTextEntry = YES; passwordField.returnKeyType = UIReturnKeyGo; [passwordField setBackgroundColor:[UIColor whiteColor]]; [_alertView addSubview:passwordField]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0.0, 00.0); [_alertView setTransform:myTransform]; }else { _alertView.title = title; usernameField.text = nil; passwordField.text = nil; }   [usernameField becomeFirstResponder]; [_alertView show];

 

 

 

自定义按钮事件代码：

其中didDismissWithButtonIndex参数为：第几个按钮点击事件

 

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{ if (buttonIndex == 1) { self.userName = usernameField.text; self.password = passwordField.text; [self performSelector:@selector(doResponse) withObject:nil afterDelay:0.1]; } }
