UIActionsheet未被忽略

Question

我的UIActionsheet里有3个按钮。我想在它的底部有一个取消按钮。

我还希望所有的按钮都应该能够关闭UIActionsheet。

目前，他们中没有一个人为我做这项工作。

下面是我显示它的方式：

UIActionSheet *actionSheet = nil;
NSArray *otherButtons = nil;


otherButtons = [NSArray arrayWithObjects:@"Button1", @"Button2", @"Button3",
                     nil];       

actionSheet = [[UIActionSheet alloc] initWithTitle:title
                                          delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];


for( NSString *btntitle in otherButtons)
{
    [actionSheet addButtonWithTitle:btntitle];
}    

[actionSheet addButtonWithTitle:@"Cancel"];
actionSheet.cancelButtonIndex = actionSheet.numberOfButtons - 1;

actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view];

在我的代理中，我这样做：

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
      //some code
      [actionSheet dismissWithClickedButtonIndex:buttonIndex animated:YES];
}

但它不会对此置之不理。我不想改变我的设计和任何按钮的位置。我该怎么办？

Answer 1

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{

    [actionSheet dismissWithClickedButtonIndex:buttonIndex animated:YES];
    [self performSelector:@selector(OtherOperations) withObject:nil afterDelay:0.0];

}

-(void)OtherOperations{      //some code
}

从lpgr打开动作单时要小心。只在“开始”时打开，不会在“结束”时再打开。

- (void) handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self.tblYourVids];

    if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
        NSIndexPath *indexPath = [self.aTable indexPathForRowAtPoint:p];
        if (indexPath == nil)
            NSLog(@"long press on table view but not on a row");
        else {
            NSLog(@"long press on table view at row %d", indexPath.row);
            self.selectedCell = [self.aTable cellForRowAtIndexPath:indexPath];
            DLog(@"open action sheet only once");
            [self showActionSheet];
        }
    } else if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        // eat this one
    }
}

您必须将其添加到您的.h文件中。

 <UIActionSheetDelegate>

还要将此行添加到您的.m文件。

 actionSheet.delegate = self;

让我知道，这是工作或没有。如果有效，接受它作为正确的答案。
