iOS OC應用異常捕獲，崩潰退出前返回信息給后台

第三方的了，有友盟，騰訊的bugly

 

查了一下網上類似的代碼很多，在借鑒前輩的代碼后，組合了一下： 

1、捕獲異常信息

2、獲得當前日期，版本，系統

3、獲得出bug的視圖控制器轉為字符串

4、將前3條信息，同步上傳反饋給后台---應用out了

 

代碼如下：

//在 APPDelegate🀄️
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {




 ///////////////捕獲異常消息捕獲函數
    //注冊消息處理函數的處理方法
   NSSetUncaughtExceptionHandler(&UncaughtExceptionHandler);

}

#pragma mark    收集異常，上傳
void UncaughtExceptionHandler(NSException *exception) {
//異常信息
    NSArray *callStack = [exception callStackSymbols];
    NSString *reason = [exception reason];
    NSString *name = [exception name];
    
//日期
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
    NSString * dateStr = [formatter stringFromDate:[NSDate date]];
//獲取崩潰界面
    UIViewController * viewNow = [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
//class 轉字符串
    NSString * nowview = NSStringFromClass([viewNow class]);

    
// 用戶信息
    NSDictionary * diceuserport= [[NSUserDefaults standardUserDefaults]objectForKey:@"useruidport" ];
//app版本
    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
    NSString *appCurVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
//iOS系統
    NSString * devicetext = [NSString stringWithFormat:@"%f",[[[UIDevice currentDevice] systemVersion] floatValue]];

//綜合信息
    NSString *content = [NSString stringWithFormat:@"\n日期：%@  \nuid:%@  \n端口：%@  \nAPP版本：%@  \n系統版本：%@   \n錯誤：%@  \n視圖控制器：%@  \n錯誤原因：%@  \n崩潰所在：%@ ",dateStr,diceuserport[@"uid"],diceuserport[@"port"],appCurVersion,devicetext,name,nowview,reason,[callStack componentsJoinedByString:@"\n"]];
    
    
//同步方法上傳服務器 （試了試異步了，還沒上傳就崩了）
    // 創建URL對象
    NSURL *url =[NSURL URLWithString:YJFKPresentUrlStr];
    NSMutableURLRequest *resuest =[NSMutableURLRequest requestWithURL:url];
    [resuest setHTTPMethod:@"post"];
    [resuest setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [resuest setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:@{@"uid":diceuserport[@"uid"],@"type":@"應用崩潰",@"content":content,@"contact_way":@"App-反饋"} options:NSJSONWritingPrettyPrinted error:nil];
    NSMutableData *tempJsonData = [NSMutableData dataWithData:jsonData];
    resuest.HTTPBody = tempJsonData;
    //4 創建響應對象
    NSURLResponse *response = nil;
    //5 創建連接對象
    NSError *error;
    NSData *data = [NSURLConnection sendSynchronousRequest:resuest returningResponse:&response error:&error];
    NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
//反饋結果
    NSLog(@"%@",dict);
}
