Question

我正在一个带有地图框架的项目中工作，一切都很好，直到我开始推送通知并在我的 AppDelegate.h 中写入 @property bool push;。我的 AppDelegate.m

里有这个

(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken {

NSString *key =[[NSUserDefaults standardUserDefaults] stringForKey:@"token"];

if ( key== nil || [key isEqual:@""])
{
    _push=true;
    NSString* token = [[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""] stringByReplacingOccurrencesOfString: @">" withString: @""] stringByReplacingOccurrencesOfString: @" " withString: @""] ;
    NSLog(@"=== Device token: %@", token);
    NSUserDefaults *userdefault = [NSUserDefaults standardUserDefaults];
    [userdefault setObject:token forKey:@"token"];

    NSString *jsonPostBody = [NSString stringWithFormat:@"{\"token\":"
                              "\"%@\""
                              ",\"type\":"
                              "\"ios\""
                              "}",
                              [token stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSData *postData = [jsonPostBody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

    NSURL *url = [NSURL URLWithString:@"http://www.turismolapalmadelcondado.es/es/api/push_notifications"];

    NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url
                                                           cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
                                                       timeoutInterval:180.0];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:postData];
    NSString* postDataLengthString = [[NSString alloc]initWithFormat: @"%d", [postData length]];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:postDataLengthString forHTTPHeaderField:@"Content-Length"];

    NSURLResponse *response = nil;
    NSError *error = nil;
    NSData *data=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    NSHTTPURLResponse *httpResponse = response;
    NSLog(@"response text: %@",[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding] );
    NSLog(@"response status code: %ld", (long)[httpResponse statusCode]);
}

}

问题是，如果我没有定义 push，我会在 AppDelegate.m 中出现错误，但如果我定义了它，那么在框架中会有 93 个相同的错误。我之前没有任何问题，我几乎尝试了我在这里找到的所有解决方案。

如果您需要更多信息，请告诉我。

谢谢。

我终于能够修复错误。我在特定框架中遇到错误，但也许我可以帮助某人。这确实是一个配置错误项目，如果你像我一样使用开源框架，请仔细阅读文档以了解需求，在我的情况下，我需要两件事才能让它工作但我找不到，我不知道是谁在看直到我看到一些需要和不需要的文件。除此之外，ios 框架的版本或诸如启用或不启用 Bitcode 或 arc 之类的东西，在我的情况下，我必须在调试中启用 Bitcode，但在发布时不启用。要了解这一点，只需查看患者的框架设置即可。希望我的经验可以帮助到一些人。
