Question

我在UIView中创建了一个名为省略的方法，这个方法正在创建一个动作表。我试图在我的UIViewController中调用这个方法但由于“[actionSheet showInView：self]”而失败。这个动作表在我的视图中工作正常，因为'自我'，但我不知道如何修复'自我'，以便它可以在我的VC和我的视图中显示。

这是我在UIView中的部分代码

- (void)ellipses{

NSString *deleteButtonName = NSLocalizedString(@"Delete", @"");
NSString *copyButtonName = NSLocalizedString(@"Copy to clipboard", @"");
NSString *cancel = NSLocalizedString(@"Cancel", @"");

NSArray *buttons;


buttons = [NSArray arrayWithObjects:deleteButtonName, copyButtonName, nil];


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

for(NSString *title in buttons)  {
    [actionSheet addButtonWithTitle:title];
}

[actionSheet addButtonWithTitle:cancel];
[actionSheet setCancelButtonIndex:[buttons count]];
[actionSheet showInView:self]; // here is gonna be a problem later
}

这是我的UIViewController

中代码的一部分

-(void)loadView{
    newView *nView = [newView new];
    [self setView:nView];
    UIButton *testButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [testButton setTitle:@"Test" forState:UIControlStateNormal];
    [testButton setFrame:CGRectMake(200, 230, 60, 28)];
    [testButton setUserInteractionEnabled:YES];
    [testButton addTarget:self action:@selector(actionSh) forControlEvents:UIControlEventTouchUpInside];
    [nView addSubview:testButton];
}

-(void)actionSh{
newView *newview = [[newView alloc] init];
[newview ellipses];//CALL ellipses
[newview setNeedsDisplay];
}

我的问题的答案：在我的VC.newView中添加此方法是我的UIView。

- (newView *) newview {

return (newView *)[self view];

}

并从我的VC调用方法

-(void)actionSH {
[[self newview] ellipses];
}

如何使用动作表showInView方法，以便它可以在我的VC和UIView中显示
