Question

我正在尝试开发一个应该执行以下操作的简单OS X应用程序：

读取文件以获取用户名和密码
从服务器获取Mac序列号
使用用户名，密码和Mac序列号
如果用户被授权与此服务连接，则应运行无限
无限循环应该调用连接到另一个服务的服务来获取新闻
如果有新闻，则应发送本地通知

此应用程序应该在没有GUI的情况下工作，因此我使用Xcode命令行工具。该应用程序组织如下：

main.m使用用户名和密码读取文件并获取Mac序列号
Connection.m应连接到登录服务并运行checkNews服务
CheckNews.m应该连接到新闻服务，如果有新闻应该运行一个类来发送本地通知
NotificationCenterDelegate.m应该只发送带有新闻的本地通知

我的问题是，如果我运行应用程序，它不会连接到登录服务，因为它不会调用NSConnectionDelegate方法。我在网上搜索，我发现连接应该在主线程中，我使用以下代码测试它：NSLog(@"Is%@ main thread", ([NSThread isMainThread] ? @"YES" : @" NOT"));并且它返回我，连接在主线程中，所以我没有＆＃39 ;不知道它为什么不运行NSConnectionDelegate方法。如果您需要，我可以发布我的Connection.m类的代码，以了解它为什么不能正常工作。我希望你能帮助我解决这个问题。

Connection.m

#import "Connection.h"
#import "CheckNews.h"

@interface Connection() {
    NSMutableData *responseData;
}

@property(nonatomic,strong)NSString *fakeBundleIdentifier;
@property BOOL installNSBundleHook;

@end

@implementation Connection

- (id)initWithFakeBundle:(NSString *)fakeBundleIdentifier andInstallNSbundleHook:(BOOL)installNSBundleHook {
    if (self) {
        self.fakeBundleIdentifier = fakeBundleIdentifier;
        self.installNSBundleHook = installNSBundleHook;
    }
    return self;
}

- (id)sendRequestToURL:(NSString *)urlString withMethod:(NSString *)method withUsername:(NSString *)username withPassword:(NSString *)password andSerialNumber:(NSString *)serialNumber {
    NSURL *finalURL;

    if ([method isEqualToString:@"POST"]) {
        finalURL = [NSURL URLWithString:urlString];
    } else {
        NSLog(@"Metodo no previsto");
    }

    NSString *post = [NSString stringWithFormat:@"username=%@&password=%@&serialNumber=%@", username, password, serialNumber];
    NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding];

    NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)postData.length];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
    [request setURL:finalURL];
    [request setHTTPMethod:method];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
    if (connection) {
        [connection start];
    }
    return connection;
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    responseData = [[NSMutableData alloc]init];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [responseData appendData:data];
}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    NSLog(@"%@", error);
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    NSDictionary *json;
    NSError *error;

    json = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];

    if ([self loginWithSuccessFromJson:json]) {
        [self checkNews];
    }

}

- (BOOL)loginWithSuccessFromJson:(NSDictionary *)json {
    int success = [[json objectForKey:@"success"]intValue];

    if (success == 1) {
        return YES;
    } else {
        return NO;
    }
}

- (void) checkNews {
    CheckNews *checkNews = [[CheckNews alloc]initWithFakeBundle:self.fakeBundleIdentifier andInstallNSbundleHook:self.installNSBundleHook];
    for(;;) {
        [checkNews sendRequestToURL:@"" withMethod:@"GET"];
    }
}

NSConnectionDelegate方法不会被执行
