对于某些用户，我的应用程序的最新版本在启动时开始崩溃。iTunes 中只有 1 个崩溃报告，如下所示。我一直无法在任何设备上重现。
两个版本之间的变化是
- 集成两个第三方库（iNotify、openUDID）
- 从 GCC 编译器切换到 Apple LLVM 3.1 编译器（新库需要 arc 支持）
- 在启用 arc 的情况下编译新库的代码，在项目的其余部分禁用 arc。
我在 iNotify 的 appdelegate 中的 didFinishLaunchingWithOptions 中添加了 1 行。从堆栈跟踪到我认为它不会在那里崩溃。
有点不知所措。任何帮助，将不胜感激。谢谢！

一些额外的代码。
在appdelegate中有一个alertview定义如下：
#import <UIKit/UIKit.h>
@class MyAPPViewController;
@interface MyAPPAppDelegate : NSObject <UIApplicationDelegate> {
UIViewController *rvc;
UIAlertView *m_cAlertControl;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
-(BOOL)shouldNag;
-(void)shouldEnableUI:(BOOL)pIsEnable;
-(void)updateRunCount;
@end
以及在应用程序委托中实现的方法如下：
-(void)shouldEnableUI:(BOOL)pIsEnable
{
if(NO == pIsEnable)
{
if (nil == m_cAlertControl) {
m_cAlertControl = [[UIAlertView alloc] init];
}
m_cAlertControl.backgroundColor = [UIColor clearColor];
m_cAlertControl.opaque = NO;
[m_cAlertControl setHidden:YES];
[m_cAlertControl show];
}
else {
if (nil != m_cAlertControl) {
[m_cAlertControl dismissWithClickedButtonIndex:0 animated:YES];
}
}
}
视图控制器对方法的调用如下：
[appDelegate shouldEnableUI:NO];
