iPhone键盘快速点击“下一步”按钮

在我的应用程序中，如果快速点击“下一步”按钮（返回键），会导致问题。有没有办法阻止用户这样做？我自己无法想到一个解决方案。iPhone键盘快速点击“下一步”按钮

我在一个UIScrollView与许多页面，并在某个页面上我有一个键盘弹出，所以用户可以键入到一个UITextField。点击下一个按钮会提示滚动视图滑动到下一页。但是，如果用户点击按钮太多，会导致滚动视图跳转。

下面的代码是当返回键被窃听，关键的部分是它调用[self setPage:6];

-(BOOL)textFieldShouldReturn:(UITextField *)textField 
{ 
    //Enter your first and last name 
    if (textField == firstnameField1) 
    { 
     //Put the text into a string to be saved 
     firstName1 = firstnameField1.text; 
     //Send user to next field (your surname) 
     [surnameField1 becomeFirstResponder]; 
    } 
    else if (textField == surnameField1) 
    { 
     //Put text into a string to be saved 
     surname1 = surnameField1.text; 
     //Move to the next stage, enter partners name 
     if (pageController.currentPage == 4) { 
      [self setPage:5]; 
     } 
     else if (pageController.currentPage == 3) 
     { 
      [self setPage:5]; 
     } 

     currentStage = stage6; 
    } 

    //Enter your partners first and last name 
    if (textField == firstnameField2) 
    { 
     //Put the text into a string to be saved 
     firstName2 = firstnameField2.text; 
     //Send user to next field (your partners surname) 
     [surnameField2 becomeFirstResponder]; 
    } 
    else if (textField == surnameField2) 
    { 
     //Put text into a string to be saved 
     surname2 = surnameField2.text; 
     //Move to the next stage, enter partners name 
     if (pageController.currentPage == 5) { 
      [self setPage:6]; 
     } 
     else if (pageController.currentPage == 4) 
     { 
      [self setPage:6]; 
     } 

     currentStage = stage7; 
    } 

    return YES; 
}

这种方法setPage低于：

-(void)setPage:(int)destinationPage 
{ 
    //Scroll to appropriate page in scroll view 
    CGRect frame = scrollViewController.frame; 
    frame.origin.x = frame.size.width * destinationPage; 
    frame.origin.y = 0; 
    [scrollViewController scrollRectToVisible:frame animated:YES]; 
}

感谢。

从你的代码看起来你正在重载Return按钮。您是否考虑实施toolbar with Next/Previous buttons，以便用户在意外超负荷时可以轻松返回跳过的字段？
