iPhone鍵盤快速點擊「下一步」按鈕

在我的應用程序中，如果快速點擊「下一步」按鈕（返回鍵），會導致問題。有沒有辦法阻止用戶這樣做？我自己無法想到一個解決方案。iPhone鍵盤快速點擊「下一步」按鈕

我在一個UIScrollView與許多頁面，並在某個頁面上我有一個鍵盤彈出，所以用戶可以鍵入到一個UITextField。點擊下一個按鈕會提示滾動視圖滑動到下一頁。但是，如果用戶點擊按鈕太多，會導致滾動視圖跳轉。

下面的代碼是當返回鍵被竊聽，關鍵的部分是它調用[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; 
}

這種方法setPage低於：

-(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]; 
}

感謝。

它會導致什麼問題？ – 2012-01-10 21:08:15

添加了代碼示例，對於之前缺乏細節感到抱歉。 – 2012-01-10 21:34:11

從你的代碼看起來你正在重載Return按鈕。您是否考慮實施toolbar with Next/Previous buttons，以便用戶在意外超負荷時可以輕鬆返回跳過的字段？
