我正在研究Ionic app并且我正在使用appsFlyer cordova插件，但不知何故，每当用户第一次打开应用程序（我的意思是每当应用程序第一次安装在设备中时）它都会出现错误和其他后续过程中断。

错误 ：

2016-04-13 11:38:44.047 WotNow[1730:35993] bool _WebTryThreadLock(bool), 0x7fd5450b4170: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now...

16  0x1066514de _pthread_wqthread
17  0x10664f341 start_wqthread

在 xcode 中，它将下面的代码突出显示为错误。

XCODE 错误代码：

-(void)onConversionDataReceived:(NSDictionary*) installData {
    NSError *error;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:installData
                                            options:0
                                            error:&error];
    if (jsonData) {
        NSString *JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding];
        [[super webView] stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"javascript:window.plugins.appsFlyer.onInstallConversionDataLoaded(%@)", JSONString]];

    } else {
        NSLog(@"%@",error);
    }
}

我不太了解Objective-c和iOS错误，所以如果有人能告诉我应该在哪里查看以及应该添加什么代码来解决此类问题，那将非常有帮助。

尝试这个 

 -(void)onConversionDataReceived:(NSDictionary*) installData {
            NSError *error;
            NSData *jsonData = [NSJSONSerialization dataWithJSONObject:installData
                                                    options:0
                                                    error:&error];
            if (jsonData) {
                NSString *JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0),^{

     [[super webView] stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"javascript:window.plugins.appsFlyer.onInstallConversionDataLoaded(%@)", JSONString]]; 
});

            } else {
                NSLog(@"%@",error);
            }
        }
