ActionsheetPicker是空白

我有ActionSheetPicker在測試項目中工作，但是當我嘗試相同的代碼粘貼到我現有的項目我看到這一點：ActionsheetPicker是空白

Blank ActionSheetPicker

我是sample code從他們的榜樣頁逐字：

NSArray *colors = [NSArray arrayWithObjects:@"Red", @"Green", @"Blue", @"Orange", nil]; 

[ActionSheetStringPicker showPickerWithTitle:@"Select a Color" 
             rows:colors 
          initialSelection:0 
            doneBlock:nil 
           cancelBlock:nil 
             origin:sender];

任何想法？

這有點傻，但我使用的是過時的ActionSheetPicker版本。你想確保你從https://github.com/skywinder/ActionSheetPicker-3.0下載分支。

實際上，iOS 8存在問題。在此之後，同樣的代碼在iOS 7中也可以使用。 UIActionSheet不適用於子類，也不應將視圖添加到其層次結構中。如果您需要提供比UIActionSheet API更多定製的工作表，您可以創建自己的模型並使用presentViewController以模態方式呈現它：動畫：完成：

UIActionSheet不被設計爲子類。創建您自己的操作表。

最後，在您的視圖控制器使用自定義操作表（即在你的按鈕動作中）。將您的選取器視圖添加爲innerView的子視圖

UIInterfaceOrientation statusBarOrientation = [[UIApplication sharedApplication] statusBarOrientation]; 
CGRect screenRect = [[UIScreen mainScreen] bounds]; 

float width = 0; 

if (UIInterfaceOrientationIsPortrait(statusBarOrientation)) { 
    width = CGRectGetWidth(screenRect); 
} else { 
    width = CGRectGetHeight(screenRect); 
} 

CustomActionSheet *actionSheet = [[CustomActionSheet alloc] init]; 

UIView *innerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, 216)]; 
[innerView setBackgroundColor:[UIColor greenColor]]; 
[innerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth]; 

[actionSheet setDelegate:self]; 
[actionSheet addContentView:innerView]; 

[innerView addSubview:self.colorsPickerView]; // Added your picker view here 

[self.actionSheet showInView:self.view];

將委託方法添加到視圖控制器。在關閉操作表時，下面的委託方法將被調用。

- (void) CustomActionSheetDoneWithUserInfo:(NSDictionary *)userInfo 
{ 
    NSLog(@"i am in delegate method of CustomAction sheet"); 
}

根據您的要求定製上述代碼。
