Question

因此，当用户想要恢复密码时，他们会点按一个按钮，子视图会显示UITextField和UIButton。用户输入电子邮件后，我希望UIButton发送电子邮件。我错过了UITextField的推荐。这是我的代码：

- (IBAction)recoverPassword:(id)sender {

CGRect frame = CGRectMake(12, 51, 298, 497);

UIView *infoView = [[UIView alloc] initWithFrame:frame];
infoView.opaque = NO;
infoView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.8f];
infoView.userInteractionEnabled = YES;
infoView.tag = 01;

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(8, 200, 280, 30)];
textField.textAlignment = NSTextAlignmentLeft;
textField.textColor = [UIColor blackColor];

UIButton *getPassword = [[UIButton alloc] initWithFrame:CGRectMake(8, 265, 280, 36)];
getPassword.backgroundColor = [UIColor blackColor];

[getPassword addTarget:self
                action:@selector(getUserPassword:)
   forControlEvents:UIControlEventTouchUpInside];

[infoView addSubview:textField];
[infoView addSubview:getPassword];
[self.view addSubview:infoView];

 }

- (void)getUserPassword:(UITapGestureRecognizer *)sendPassword {

[PFUser requestPasswordResetForEmailInBackground:**Missing Part**];
[[self.view viewWithTag:01] removeFromSuperview];
NSLog(@"Dissmissed Info SubView");
}

看起来您只在本地范围（方法范围内）创建子视图（UITextField，UIButton等），因此同一类的其他方法无法访问它们。尝试为您拥有这些方法的类创建一个ivar，并将值分配给ivar，这样就可以在-getUserPassword:方法中访问相同的变量。

P.S。同样的方法，但应用于infoView，将无需通过viewWithTag访问它，因为您可以直接访问它。
