UIActionSheet 在第二次单击按钮时关闭

发布于 2024-12-23 14:16:12 字数 693 浏览 3 评论 0原文

我有一个带有“编辑”和“删除”按钮的操作表，两者都是其他按钮这是我为其编写的代码

-(void)method1
{

    action = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil     destructiveButtonTitle:nil otherButtonTitles:@"Edit", @"Delete", nil];
     action.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
    [action showInView:self.view];
    [action release]; 

}

我已使用删除方法将操作分配给方法..

-(void)actionSheet:(UIActionSheet *)action didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if(buttonIndex == 0)
    {
        // do something
    }
    if(buttonIndex == 1)
    {
        // do something
    }
}

现在的问题是操作表不会一键关闭任一按钮..请帮我解决问题。

I have an actionSheet with EDIT and DELETE buttons, both being other buttons This is the Code i have written for it

-(void)method1
{

    action = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil     destructiveButtonTitle:nil otherButtonTitles:@"Edit", @"Delete", nil];
     action.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
    [action showInView:self.view];
    [action release]; 

}

I have used the deleate method to assign actions to method..

-(void)actionSheet:(UIActionSheet *)action didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if(buttonIndex == 0)
    {
        // do something
    }
    if(buttonIndex == 1)
    {
        // do something
    }
}

now the problem is that the actionsheet does not dismiss at one click of either of the buttons.. Please help me with some solution.

这似乎是iOS4.0中的一个错误。我在模拟器中遇到了这个问题。我把版本改成了4.3和5.0，看起来还可以。

编辑：

似乎我的问题更具体地与委托方法“-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField”启动操作表两次有关，

不知道为什么在此调用两次情况，但不是其他情况（我再次假设 iOS 4.0 的错误已在以后的版本中修复）。我的解决方法是跟踪它是否已被调用，并且不再调用它。

我建议执行以下操作：

-(void)method1
{
    if(hasLaunchedActionSheet)
    {
        return;
    }

    hasLaunchedActionSheet = YES;
    ...

and:

-(void)actionSheet:(UIActionSheet *)action didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    hasLaunchedActionSheet = NO;
    ...

对我来说，问题不在于 Xcode，而在于 iOS SDK 本身调用我的事件两次。我不确定您如何调用 method1，因此不同事件可能会出现不同的问题。

This appears to be a bug in iOS4.0. I had this issue in my simulator. I changed the version to 4.3 and 5.0 and it seemed ok.

Edit:

Seems that my issue was more specifically to do with the actionsheet being launched twice by a delegate method "-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField"

Not sure why this is called twice in this case but not others (again I assume a iOS 4.0 bug that's been fixed in later releases). My workaround is to keep track if it's been called already and not call it a second time.

Edit 2

I would suggest doing something like:

-(void)method1
{
    if(hasLaunchedActionSheet)
    {
        return;
    }

    hasLaunchedActionSheet = YES;
    ...

and:

-(void)actionSheet:(UIActionSheet *)action didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    hasLaunchedActionSheet = NO;
    ...

For me, the issue's not so much in Xcode as it is in the iOS SDK itself calling my event twice. I'm not sure how you're calling method1 so it might be a different issue with a different event.
