我的应用的最新版本在启动时已经开始为某些用户崩溃。 itunes中只有一个崩溃报告，包含在下面。我无法在任何设备上重现。
两个版本之间的变化是
我在ideotify的appdelegate中为didFinishLaunchingWithOptions添加了1行。从堆栈跟踪到我不认为它在那里崩溃。
有点不知所措。任何帮助，将不胜感激。谢谢！

一些额外的代码。
appdelegate中定义了一个alertview，如下所示：
#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app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];
}
}
}
View控制器调用这样的方法：
[appDelegate shouldEnableUI：NO];
答案 0 :(得分：4)
看到崩溃日志后，问题似乎已在UIAlertViewDelegate发布后调用。
您需要在使用警报的控制器中释放它 -
-(void)dealloc {
self.alertView.delegate = nil; //setting delegate to nil
self.alertView = nil; //if you have defined alert as property
//other release statements of your controller
[super dealloc];
}
如果您需要其他信息，可以添加应用的一些代码，或者您的应用不是这种情况。
编辑1 -
-(void)dealloc {
m_cAlertControl.delegate = nil; //setting delegate to nil
[m_cAlertControl release];
//other release statements of your controller
[super dealloc];
}

我会说这是你拥有的最大指针
[NSObject doesNotRecognizeSelector:] + 175
看起来你某处缺少选择器方法。
