iphone - iOS 崩溃日志捕获、调试信息...捕获并通过电子邮件发送给开发团队

Question

最近我们遇到了一种情况，我们想从用户设备上的应用程序中查看调试信息。所以，我正在寻找的是一种在设备上找到日志的方法，将其作为内嵌文本粘贴到邮件中并允许用户发送。

有什么想法吗？这里又是问题..1)在设备上找到调试日志2) 打开文件并将文件内容作为内联文本附加到邮件中。3) 允许用户在下次应用程序启动时通过电子邮件发送。

谢谢，

感谢所有输入的人..我将您的解决方案组合成一个可以解决我的问题的解决方案..这就是我做的..当然我没有编译代码，它是半生不熟的代码..但是当我在我的代码中实现它时，我会尽快解决它。

NS登录文件How to NSLog into a file日志文件

#if TARGET_IPHONE_SIMULATOR == 0    
    NSArray *paths =  
    NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);        
    NSString *documentsDirectory = [paths objectAtIndex:0];    
    NSString *logPath = [documentsDirectory stringByAppendingPathComponent:@"console.log"];    
    freopen([logPath cStringUsingEncoding:NSASCIIStringEncoding],"a+",stderr);
#endif

捕获崩溃并将它们也记录到文件中

首先，创建一个函数来处理错误并将其输出到控制台(以及您想用它做的任何其他事情):

void uncaughtExceptionHandler(NSException *exception) {    
    NSLog(@"CRASH: %@", exception);      
    NSLog(@"Stack Trace: %@", [exception callStackSymbols]);    
    // Internal error reporting
}

接下来，将异常处理程序添加到您的应用委托(delegate)中:

-(BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:  
(NSDictionary*)launchOptions
{   
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);    // Normal launch stuff
}

在info.plist中设置一个名为Crashed的变量，然后这样读写

- (void)readPlist
 {
      NSString *localizedPath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"plist"];        
      NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:localizedPath];

    NSString *crashed;
    crashed = [plistDict objectForKey:@"Crashed"];
}


- (void)writeToPlist
{
    NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:filePath];

    [plistDict setValue:@"YES" forKey:@"Crashed"];
    [plistDict writeToFile:filePath atomically: YES];
}

应用启动后，阅读 info.plist 并提示用户提交崩溃日志。

{
    MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
    mailComposer.mailComposeDelegate = self;[mailComposer setSubject:@"Crash Log"];
    // Set up recipients
    NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"]; 
    [mailComposer setToRecipients:toRecipients];
    // Attach the Crash Log..
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *logPath = [documentsDirectory stringByAppendingPathComponent:@"console.log"];
    NSData *myData = [NSData dataWithContentsOfFile:logPath];
    [mailComposer addAttachmentData:myData mimeType:@"Text/XML" fileName:@"Console.log"];
    // Fill out the email body text
    NSString *emailBody = @"Crash Log";
    [mailComposer setMessageBody:emailBody isHTML:NO];
    [self presentModalViewController:mailComposer animated:YES];
}
