我正在尝试了解打开应用程序时发生的崩溃问题的崩溃日志。当用户打开应用程序时,它会立即崩溃。
以下是崩溃日志中的行:
Exception Type: EXC_CRASH (SIGABRT)

在对与myApp相关的线程0和第1帧进行符号化后,它看起来像这样:
__39+[CLSUserDefaults standardUserDefaults]_block_invoke (in myApp) + 24
在对与myApp相关的线程0和第5帧进行符号化后,它看起来像这样:
-[AppDelegate application:handleOpenURL:] (in iPegs) (AppDelegate.m:448)
从第一个结果[CLSUserDefaults standardUserDefaults]
开始,我没有理解任何可能导致myApp崩溃以及在何处找到该代码的内容。
从第二个结果[AppDelegate application:handleOpenURL:]
第448行包含以下代码:
[Flurry logEvent:@"Import Document" withParameters:[NSMutableDictionary dictionaryWithObjectsAndKeys:@"Import Document",@"category",@"Import",@"action",@"open",@"label", nil] timed:YES];
函数handleOpenURL如下:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
if ([[DBSession sharedSession] handleOpenURL:url])
{
if ([[DBSession sharedSession] isLinked])
{
[[NSNotificationCenter defaultCenter] postNotificationName:COMMNAD_EXPORT_DROPBOX object:nil userInfo:nil];
}
return YES;
}
else
{
if ([[ipegsClient shareInstance]getLoginUser]!=nil)
{
id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"Import Document" // Event category (required)
action:@"Import" // Event action (required)
label:@"open" // Event label
value:[NSNumber numberWithInt:1]] build]];
[Flurry logEvent:@"Import Document" withParameters:[NSMutableDictionary dictionaryWithObjectsAndKeys:@"Import Document",@"category",@"Import",@"action",@"open",@"label", nil] timed:YES];
[[NSNotificationCenter defaultCenter] postNotificationName:COMMAND_IMPORT_FILE_DOCUMENT object:url];
return YES;
}
else
{
UIAlertView *alr = [[UIAlertView alloc]initWithTitle:@"myApp" message:@"Please login to import" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alr show];
return NO;
}
return YES;
}
// Add whatever other url handling code your app requires here
return NO;
}
那么请你帮我理解一下吗?
