问题描述
有没有办法通过编程方式访问iphone崩溃日志文件。我试图写一个崩溃报告功能,当你在崩溃后启动应用程序时,它会提供将崩溃报告发送到服务器。我找不到如何在应用程序中获取崩溃日志。
Is there a way to access iphone crash log file via programmatically. I trying to write a crash report feature that when you launch the app after a crash, it will offer to send the crash report to the server. I can't find how to get the crash log within the app.
推荐答案
您可以使用以下逻辑。
aslmsg q, m;
int i;
const char *key, *val;
float how_old = fTime ;
q = asl_new(ASL_TYPE_QUERY);
asl_set_query(q, ASL_KEY_LEVEL, strLoggerLevel ,ASL_QUERY_OP_LESS_EQUAL);
asl_set_query(q, ASL_KEY_FACILITY, [@"YourBundleIdOfAPP" UTF8String] ,ASL_QUERY_OP_EQUAL);
asl_set_query(q, ASL_KEY_TIME, [[NSString stringWithFormat:@"%.f", [[NSDate date] timeIntervalSince1970] - how_old] UTF8String], ASL_QUERY_OP_GREATER_EQUAL);
int goInside=0;
aslresponse r = asl_search(NULL, q);
while (NULL != (m = aslresponse_next(r)))
{
NSString *cValueToWrite;
NSMutableDictionary *tmpDict = [NSMutableDictionary dictionary];
for (i = 0; (NULL != (key = asl_key(m, i))); i++)
{
//get the only required fields
if(i==12 || i==10 || i==11 || i==8 || i==9 ||i==3)
{
NSString *keyString = [NSString stringWithUTF8String:(char *)key];
val = asl_get(m, key);
NSString *string = [NSString stringWithUTF8String:val];
[tmpDict setObject:string forKey:keyString];
}
}
cValueToWrite=[[NSString alloc]initWithFormat:@"\n--------------[Debug]----------------\nDateTime: %@\nApplication: %@\nInfo: %@",[tmpDict valueForKey:@"CFLog Local Time"],[tmpDict valueForKey:@"Sender"],[tmpDict valueForKey:@"Message"]];
}
strLoggerLevel
是 NSString
,它包含您想要的记录器类型,其范围最多为7个。
strLoggerLevel
is the NSString
which holds the logger type which you want which ranges upto 7.
