从UIActionSheet弹出窗口中去除填充

Question

我正在创建一个UIActionSheet，允许用户拍摄或选择照片。有人能告诉我为什么它不能像苹果的一样显示吗？这是为iPad设计的，所以我没有声明取消按钮。

UIActionSheet *actionSheet = [[UIActionSheet alloc] init];
actionSheet.delegate = self;
[actionSheet addButtonWithTitle:NSLocalizedString(@"choosePhotoPopoverButton", @"Choose Photo - Get a photo from the album.")];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
    [actionSheet addButtonWithTitle:NSLocalizedString(@"takePhotoPopoverButton", @"Take Photo - Use camera to take photo.")];
}
[actionSheet showFromRect:self.imageView.frame inView:self animated:YES];

苹果的通讯录应用。边距很小，行之间有线条。

这是我的工作示例应用。底部有额外的填充，行之间没有线条。

感谢您提供的任何见解。

试试这个

UIActionSheet *actionSheet;

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
    actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate: self cancelButtonTitle:@"" destructiveButtonTitle:nil otherButtonTitles:@"Take Photo",@"Camera", nil];
}else{
    actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate: self cancelButtonTitle:@"" destructiveButtonTitle:nil otherButtonTitles:@"Take Photo", nil];
}

[actionSheet showFromRect:self.imageView.frame inView:self animated:YES];

你仍然需要声明一个取消按钮。当在iPad上运行时，它将简单地忽略取消按钮，而在iPhone上，则会使用它。

糟糕！这似乎解释了它。谢谢。 - DenVog

我想保持使用 addButtonWithTitle 的灵活性，但不幸的是，在 iPad 上，它不会在底部按钮上方显示一条线。这个方法很有效。如果有取消按钮，iPad 会自动切掉最后一个按钮。如果你在 iPad 上，就不需要取消按钮。

UIActionSheet *actionSheet = [[UIActionSheet alloc] init];
actionSheet.delegate = self;
[actionSheet addButtonWithTitle:NSLocalizedString(@"choosePhotoPopoverButton", @"Choose Photo - Get a photo from the album.")];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
    [actionSheet addButtonWithTitle:NSLocalizedString(@"takePhotoPopoverButton", @"Take Photo - Use camera to take photo.")];
}
actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:(@"Cancel");
[actionSheet showFromRect:self.imageView.frame inView:self animated:YES];
