如何在表格视图单元格中使用带有UIKeyboard的工具栏

Question

我在[UITextView(toolbar) addKeyboardToolbar]时遇到问题，在tableView:CellForRowAtIndexPath我添加了此方法，如[cell.textView addKeyboardToolbar];

我在Crashly中遇到了像

这样的问题

  

崩溃：com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS at at   0x00000008

这是我的代码如下。 有谁可以帮我这个 提前谢谢。

- (void)addKeyboardToolbar
{
    UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.bounds.size.width, 44.0f)];
    [toolBar setBarStyle:UIBarStyleBlack];
    [toolBar setTranslucent:YES];
//  toolBar.items=[NSArray arrayWithObjects: [[UIBarButtonItem alloc]initWithTitle:@"Spacer" style:UIBarButtonItemStyleBordered target:self action:nil],
//                 [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
//                 [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(hideKeyboard)],
//                 nil];
//  [toolBar sizeToFit];

    UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(hideKeyboard)];

    [toolBar setItems:[NSArray arrayWithObjects:spacer, done, nil] animated:YES];
    [toolBar setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];

    if ([self isKindOfClass:UITextField.class]) {
        [self setInputAccessoryView:toolBar];
    } else if ([self isKindOfClass:UITextView.class]) {
        [self setInputAccessoryView:toolBar];
    }

    //return toolBar;
}
