多个UIActionSheets在同一代表 [英] Multiple UIActionSheets on the same delegate

问题描述

我正在写一个益智游戏。当用户按下检查按钮时，我看到他们输入的解决方案是否正确。根据结果​​，我提出了两个动作单。现在我只需要一些NSLog语句来确保事情得到调用，但只有其中一个表似乎可以正常工作。

当我点击showErrorsActionSheet 中的按钮。该操作表从屏幕上消失，但是日志永远不会打印。

我怀疑它与向同一代表（self）声明的两个动作相关p>

   - （void）checkSolution {
 
 //代码确定BOOL的值allCorrect 
 
 if（allCorrect）{//如果所有的字母都有正确的
 //显示UIAlertView; 
 NSLog（@allCorrect）; 
 UIActionSheet * levelCompleteActionSheet = [[UIActionSheet alloc] initWithTitle：@恭喜！你已经完成了！委托：self cancelButtonTitle：@查看我的工作destructiveButtonTitle：@选择下一个谜题otherButtonTitles：nil，nil]; 
 [levelCompleteActionSheet showInView：self.view]; 
 [levelCompleteActionSheet release]; 
} 
 else {
 // [self showIncorrectLettersInRed]; 
 
 UIActionSheet * showErrorsActionSheet = [[UIActionSheet alloc] initWithTitle：@对不起，这不对，显示红色的错误？委托：self cancelButtonTitle：@不，谢谢，我会继续努力destructiveButtonTitle：@是的，我被卡住了！ otherButtonTitles：nil，nil]; 
 [showErrorsActionSheet showInView：self.view]; 
 [showErrorsActionSheet release]; 
} 
} 
  

应该调用的方法是： / p>

   - （void）levelCompleteActionSheet：（UIActionSheet *）actionSheet didDismissWithButtonIndex：（NSInteger）buttonIndex {
 if（buttonIndex！= [actionSheet cancelButtonIndex]）{
 NSLog（@return to levelSelect）; 
 // pushViewController：levelSelect 
} 
 else {
 NSLog（@继续检查解决方案）; 
 
 
 
 
  - （void）showErrorsActionSheet：（UIActionSheet *）actionSheet didDismissWithButtonIndex：（NSInteger）buttonIndex {
 if（buttonIndex！= [ actionSheet cancelButtonIndex]）{
 NSLog（@show errors in red）; 
} 
 else {
 NSLog（@继续尝试）; 
} 
} 
  

，Ive在界面文件中声明了UIActionSheet协议如下：

  @interface GamePlay：UIViewController< UIActionSheetDelegate> {
  

解决方案

为每个actionSheet设置一个标签，然后使用

分配标签

   - （void）checkSolution 
 {
 if（allCorrect）
 {
 UIActionSheet * levelCompleteActionSheet = [[UIActionSheet alloc] initWithTitle： @恭喜！你已经完成了！委托：self cancelButtonTitle：@查看我的工作destructiveButtonTitle：@选择下一个谜题otherButtonTitles：nil，nil]; 
 
 [levelCompleteActionSheet setTag：0]; 
 
 [levelCompleteActionSheet showInView：self.view]; 
 [levelCompleteActionSheet release]; 
} 
 else 
 {
 UIActionSheet * showErrorsActionSheet = [[UIActionSheet alloc] initWithTitle：@对不起，这不对，显示红色错误？委托：self cancelButtonTitle：@不，谢谢，我会继续努力destructiveButtonTitle：@是的，我被卡住了！ otherButtonTitles：nil，nil]; 
 
 [showErrorsActionSheet setTag：1]; 
 
 [showErrorsActionSheet showInView：self.view]; 
 [showErrorsActionSheet release]; 
} 
} 
  

UIActionSheet委托

   - （void）actionSheet：（UIActionSheet *）actionSheet clickedButtonAtIndex：（NSInteger）buttonIndex 
 {
开关（actionSheet.tag）
 {
 case 0：/ * levelCompleteActionSheet * / 
 {
开关（buttonIndex）
 {
案例0：/ *第一个按钮* / 
 break ; 
案例1：/ *第二按钮* / 
 break; 
} 
} 
 break; 
案例1：/ * showErrorsActionSheet * / 
 break; 
} 
} 
  

同样适用于此类中的其他任何地方，包括 levelCompleteActionSheet：和 showErrorsActionSheet：。唯一的区别是，您需要为每个actionSheet创建一个iVar，而不是在 checkSolution 中创建它们。

I'm writing a puzzle game. When the user presses the check button, I see if the solution they entered is correct. Depending on the result, I present one of two action sheets for them. For now I just have some NSLog statements to make sure things are getting called, but only one of the sheets seems to work properly.

Nothing gets called when I click a button in showErrorsActionSheet. The action sheet disappears off the screen, but the logs never print.

I suspect it has something to do with having two actionsheets declared to the same delegate (self)

- (void) checkSolution {

    //code determines the value of the BOOL allCorrect 

    if (allCorrect) { //IF ALL OF THE LETTERS WERE CORRECT
        //display UIAlertView;
        NSLog(@"allCorrect");
        UIActionSheet *levelCompleteActionSheet = [[UIActionSheet alloc] initWithTitle:@"Congratulations! You Have Finished the Level!" delegate:self cancelButtonTitle:@"Review my work" destructiveButtonTitle:@"Choose next puzzle" otherButtonTitles:nil, nil];
        [levelCompleteActionSheet showInView:self.view];
        [levelCompleteActionSheet release];
    }
    else {
        //[self showIncorrectLettersInRed];

        UIActionSheet *showErrorsActionSheet = [[UIActionSheet alloc] initWithTitle:@"Sorry, thats not right. Show errors in red?" delegate:self cancelButtonTitle:@"No Thanks, I'll keep trying" destructiveButtonTitle:@"Yes please, I'm stuck!" otherButtonTitles:nil, nil];
        [showErrorsActionSheet showInView:self.view];
        [showErrorsActionSheet release];
    }
}

the methods that are supposed to be called are:

- (void) levelCompleteActionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
    if (buttonIndex != [actionSheet cancelButtonIndex]) {
        NSLog(@"return to levelSelect");
        //pushViewController:levelSelect
    }
    else {
        NSLog(@"continue to examine solution");
    }
}


- (void) showErrorsActionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
    if (buttonIndex != [actionSheet cancelButtonIndex]) {
        NSLog(@"show errors in red");
    }
    else {
        NSLog(@"continue to try");
    }
}

and Ive declared the UIActionSheet protocol in the interface file as follows:

@interface GamePlay : UIViewController <UIActionSheetDelegate> {

解决方案

Set a tag for each actionSheet, then use a switch statement in the UIActionSheet delegate.

Assign a tag

- (void)checkSolution
{
    if (allCorrect) 
    {
        UIActionSheet *levelCompleteActionSheet = [[UIActionSheet alloc] initWithTitle:@"Congratulations! You Have Finished the Level!" delegate:self cancelButtonTitle:@"Review my work" destructiveButtonTitle:@"Choose next puzzle" otherButtonTitles:nil, nil];

        [levelCompleteActionSheet setTag: 0];

        [levelCompleteActionSheet showInView:self.view];
        [levelCompleteActionSheet release];
    }
    else
    {    
        UIActionSheet *showErrorsActionSheet = [[UIActionSheet alloc] initWithTitle:@"Sorry, thats not right. Show errors in red?" delegate:self cancelButtonTitle:@"No Thanks, I'll keep trying" destructiveButtonTitle:@"Yes please, I'm stuck!" otherButtonTitles:nil, nil];

        [showErrorsActionSheet setTag: 1];

        [showErrorsActionSheet showInView:self.view];
        [showErrorsActionSheet release];
    }
}

UIActionSheet Delegate

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex 
{
    switch ( actionSheet.tag )
    {
        case 0: /* levelCompleteActionSheet */
        {
            switch ( buttonIndex )
            {
                case 0: /* 1st button*/
                    break;
                case 1: /* 2nd button */
                    break;
            }
        }
            break;
        case 1: /* showErrorsActionSheet */
            break;
    }
}

The same would apply anywhere else in this class as well, including levelCompleteActionSheet: and showErrorsActionSheet:. The only difference is, you would need to create an iVar for each actionSheet instead of creating them in checkSolution.
