UISplitViewController EXC_BAD_ACCESS上旋轉使用ARC

我使用ARC一個UISplitViewController但似乎很少旋轉事件後要崩潰：UISplitViewController EXC_BAD_ACCESS上旋轉使用ARC

Exception Type: EXC_BAD_ACCESS (SIGSEGV) 
Exception Codes: KERN_INVALID_ADDRESS at 0x80069f69 
Crashed Thread: 0 

Thread 0 name: Dispatch queue: com.apple.main-thread

5 UIKit       0x356be7a4 -[UITableView _userSelectRowAtPendingSelectionIndexPath:] + 152

此外，當我啓動應用程序，我得到這個錯誤：

Splitview controller <PUCSplitViewController: 0x36c290> is expected to have a master view controller before its used!

我錯過了什麼？我將其設置得非常類似於Apple提供的示例項目。

而且有時崩潰切換詳細視圖時：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 

    // Clicked Asset 
    Asset *asset = [items objectAtIndex:indexPath.row]; 

    UIViewController *detailViewController = nil; 

    // See what asset we are on 
    if ([asset.title isEqualToString:@"News"]) { 
     News2 *news = [[News2 alloc] initWithStyle:UITableViewStyleGrouped]; 
     UINavigationController *newsNav = [[UINavigationController alloc] initWithRootViewController:news]; 
     detailViewController = newsNav; 
    } else if ([asset.title isEqualToString:@"Photos"]) { 
     PhotosiPad *photos = [[PhotosiPad alloc] init]; 
     UINavigationController *photosNav = [[UINavigationController alloc] initWithRootViewController:photos]; 
     detailViewController = photosNav; 
    } 

    // Update the split view 
    [PUCAppDelegate instance].mainSplitViewController.viewControllers = [NSArray arrayWithObjects:self.navigationController, detailViewController, nil]; 

    // Dismiss the popover if it's present. 
    if (popoverController != nil) { 
     [popoverController dismissPopoverAnimated:YES]; 
    } 

}//end

這裏是我創建UISplitViewController在applicationDidFinishLoading：

PUCSplitViewController *splitPUC = [[PUCSplitViewController alloc] init]; 
self.mainSplitViewController = splitPUC; 
[self.window addSubview:self.mainSplitViewController.view]; 
[self.window makeKeyAndVisible];

想法？

發佈您的applicationDidFinishLoading代碼。 – fbernardo 2012-03-13 02:01:58

謝謝，剛添加它。 – 2012-03-13 03:59:05

因此，您的splitviewcontroller應用程序啓動時沒有viewcontrollers？通過崩潰日誌，我敢打賭，uisplitviewcontrolller代表被釋放。請嘗試使用殭屍。 – fbernardo 2012-03-13 08:23:35

爲

is expected to have a master view controller before its used!

錯誤，

你需要在設置爲splitviewcontroller視圖控制器設置委託。

請參閱Use Your Loaf blog from April 6th, 2012（不，它不是我的）。

謝謝，我偶然發現了同樣的問題，問題是我沒有將代理設置到新的詳細視圖控制器。你的答案引導了... – 2015-04-13 16:34:02
