Question

我有一个动作表，当我单击“是”按钮时，似乎只调用clickedButtonAtIndex委托方法，而不是“否”按钮...这是代码：

self.myActionSheet = [[UIActionSheet alloc] initWithTitle:@"Test" delegate:self
      cancelButtonTitle:@"No" destructiveButtonTitle:@"Yes" otherButtonTitles:nil];
[self.myActionSheet showInView:self.view];
[myActionSheet release];

然后是委托方法：

- (void)actionSheet:(UIActionSheet *)myActionSheet
     clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 1) {
        [self.myActionSheet dismissWithClickedButtonIndex:1 animated:YES];
        return;
    }

除非我触摸，否则我在此程序第一行的断点不会被击中 “是”按钮。我已将此更改为cancelButtonTitle：nil然后将“No”放在另一个按钮上（otherButtonTitles：@“No”，nil）。同样的事情。

任何帮助？
谢谢！

Answer 1

尝试触摸否按钮的顶部。它有效吗？

您是否有标签栏或工具栏？如果是这样，请尝试从标签栏或工具栏中显示操作表。条形图可以部分遮挡“否”按钮。

不，它不是一个错误..只是一个“房地产”问题。从UIActionSheet标题看看API ..

// show a sheet animated. you can specify either a toolbar, a tab bar, a bar butto item or a plain view. We do a special animation if the sheet rises from
// a toolbar, tab bar or bar button item and we will automatically select the correct style based on the bar style. if not from a bar, we use
// UIActionSheetStyleDefault if automatic style set
- (void)showFromToolbar:(UIToolbar *)view;
- (void)showFromTabBar:(UITabBar *)view;
- (void)showFromBarButtonItem:(UIBarButtonItem *)item animated:(BOOL)animated __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_3_2);
- (void)showFromRect:(CGRect)rect inView:(UIView *)view animated:(BOOL)animated __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_3_2);
- (void)showInView:(UIView *)view;

UIActionSheet委托方法不会被调用
