新建一個類CatchCrash

@interface CatchCrash : NSObject
void uncaughtExceptionHandler(NSException *exception);
@end

@implementation CatchCrash
void uncaughtExceptionHandler(NSException *exception){
    
    NSArray *stackArry= [exception callStackSymbols];

    NSString *reason = [exception reason];
    
    NSString *name = [exception name];
    
    NSString *exceptionInfo = [NSString stringWithFormat:@"Exception name:%@\nException reatoin:%@\nException stack :%@",name,reason,stackArry];
    NSLog(@"exceptionInfo------>");
    NSLog(@"%@",exceptionInfo);
    
    //儲存到本地沙盒中
    
    [exceptionInfo writeToFile:[NSString stringWithFormat:@"%@/Documents/error.log",NSHomeDirectory()] atomically:YES encoding:NSUTF8StringEncoding error:nil];
    
    
    
}


@end
 

AppDelegate匯入標頭檔案，在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中加入如下處理，獲取log檔案之後就可以走介面提交到後臺了，在後臺檢視相關日誌。

    //註冊訊息處理函式的處理方法
    
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
    
    // 傳送崩潰日誌
    
    NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    
    NSString *dataPath = [path stringByAppendingPathComponent:@"error.log"];
    
    NSData *data = [NSData dataWithContentsOfFile:dataPath];
    
    if (data != nil) {
        //上傳log
        
    }
