我的一位用戶報告他的設備iPhone 3GS發生崩潰。其他類型的設備不報告類似的行爲。他給我發送了一個崩潰日誌,並基於閱讀它,我不知道如何繼續。我希望我不會錯誤地解釋崩潰日誌,但它看起來並不像我的操作已被調用。完整性檢查:UIBarButtonItem崩潰嘗試執行操作
這是我如何創建和設置的UIBarButtonItem:
- (void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addLog:)];
self.navigationItem.rightBarButtonItem = addButton;
[addButton release];
}
這是我的操作方法:
- (IBAction)addLog:(id)sender {
MyViewController *myController = [[MyViewController alloc] initWithNibName:@"MyNib" bundle:nil];
UINavigationController *subNavigationController = [[UINavigationController alloc] initWithRootViewController: myController];
[self presentModalViewController:subNavigationController animated:YES];
[myController release];
[subNavigationController release];
}
這是崩潰日誌:

謝謝!我能夠確定導致該信息崩潰的原因。 – Giao 2010-03-30 13:53:12
沒問題。請記住,對於將來的版本,請確保保存.dSYM和App Bundles。 Xcode 3.2.2可能有一個功能來幫助強制執行此操作;) – Jasarien 2010-03-30 13:56:02
