iOS崩溃日志捕获，调试信息..捕获并通过电子邮件发送到开发团队 [英] iOS crash log catch, debug info.. Catch and send via email to the Dev team

问题描述

最近我们遇到了一个情况，我们想看到用户在他的设备上的应用程序的调试信息。所以，我要找的是一种方法来查找设备上的日志，将其粘贴为邮件上的内联文本，并允许用户发送它。

Recently we came across a situation where we wanted to see the debug info from the app which a user has on his device. So, what I am looking for is a way to find the log on the device, paste it as inline text on a mail and allow the user to send it..

有任何想法吗？这里是问题再次..
1）在设备上查找调试日志
2）打开文件，并将文件的内容作为内联文本附加到邮件。
3）允许用户在下次启动应用程序时向其发送电子邮件。

Any ideas? Here are the questions again.. 1)Find a debug log on the device 2)open the file and attach the contents of the file as inline text in to the mail. 3)Allow the user to email it the next time app launches..

感谢，

推荐答案

感谢所有的输入家伙..我把你的解决方案成一个，将解决我的问题..这是我做的是.. ..当然没有编译代码，它是一个半烘焙的代码..但我会尽快熨烫它，我实现它在我的代码..

Thanks for all the inputs guys.. I clubbed your solutions into one that would solve my problem.. Here is what I made it to be.. Surely I did not compile the code, it is a half baked code.. but I will iron it soon once as I implement it in my code..

NSLog到文件如何NSLog登入档案 LOG2FILE

NSLog into file How to NSLog into a file LOG2FILE

#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

捕获崩溃并将其记录到文件

Catch the Crash and Log them too into a File

首先，创建一个函数来处理错误并将其输出到控制台（以及任何你想要做的事情）：

First, create a function that will handle the error and output it to the console (as well as whatever else you want to do with it):

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

您的应用程式委托：

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

在info.plist中设置一个变量

Set a variable in the info.plist called Crashed and then read/write it this way

- (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];
}

应用程式启动后，读取info.plist并提示使用者

{
    MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
    mailComposer.mailComposeDelegate = self;[mailComposer setSubject:@"Crash Log"];
    // Set up recipients
    NSArray *toRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 
    [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];
}
