小编use*_*352的帖子

现在我有xcode 6.0(Beta)作为我的xcode的默认版本.

今天我从app store安装了xcode 6,但我想将xcode 6设置为默认版本.

我怎么设置它？

提前致谢.

我使用AFNetworking库使用POST方法在服务器上发布数据.

以下是我的代码

- (void) callLoginAPI:(NSDictionary *)dictProfile{
    // 1
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:[dictProfile valueForKey:@"name"], @"username",
                                                                    [dictProfile valueForKey:@"first_name"],@"first_name",
                                                                    [dictProfile valueForKey:@"last_name"],@"last_name",
                                                                    [dictProfile valueForKey:@"email"],@"email",
                                                                    [dictProfile valueForKey:@"birthday"],@"dob",
                                                                    [dictProfile valueForKey:@"gender"],@"gender",
                                                                    [[dictProfile valueForKey:@"location"] valueForKey:@"name"],@"location",
                                                                    [dictProfile valueForKey:@"timezone"],@"timezone",
                                                                    @"",@"language",
                                                                    [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large",[dictProfile valueForKey:@"id"]],@"profile_pic_url",
                                                                    @"",@"cover_pic_url",nil];



    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];



    [manager POST:@"http://10.1.81.35:8000/api/login/" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

但我得到了以下错误的回应

Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text …

我在我的应用程序中使用afnetworking.

要在服务器上发布数据,我写了以下代码

- (void) callLoginAPI:(NSDictionary *)dictProfile{
    // 1

    NSDictionary *params = @{@"username":[dictProfile valueForKey:@"name"],
                             @"first_name":[dictProfile valueForKey:@"first_name"],
                             @"last_name":[dictProfile valueForKey:@"last_name"],
                             @"email":[dictProfile valueForKey:@"email"],
                             @"dob":[dictProfile valueForKey:@"birthday"],
                             @"gender":[dictProfile valueForKey:@"gender"],
                             @"location":[[dictProfile valueForKey:@"location"] valueForKey:@"name"],
                             @"timezone":[dictProfile valueForKey:@"timezone"],
                             @"language":@"",
                             @"profile_pic_url":[NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large",[dictProfile valueForKey:@"id"]],
                             @"cover_pic_url":@""
                             };

    NSString* HOST_URL = [NSString stringWithFormat:@"%@login/",BASE_URL];

    AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
    operationManager.requestSerializer = [AFJSONRequestSerializer serializer];

    [operationManager POST:HOST_URL parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject){
        NSLog(@"resp:%@",responseObject);
        // Enter what happens here if successsful.

    }failure:^(AFHTTPRequestOperation *operation, NSError *error){
        NSLog(@"error:%@",error);
        // Enter what happens here if failure happens

    }];
}

但作为回应我得到了以下错误

我正在使用AFnetworking库在服务器上发布数据.

以下是我在服务器上发布数据的代码.

- (void) callLoginAPI:(NSDictionary *)dictProfile{
    // 1
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:[dictProfile valueForKey:@"name"], @"username",
                                                                    [dictProfile valueForKey:@"first_name"],@"first_name",
                                                                    [dictProfile valueForKey:@"last_name"],@"last_name",
                                                                    [dictProfile valueForKey:@"email"],@"email",
                                                                    [dictProfile valueForKey:@"birthday"],@"dob",
                                                                    [dictProfile valueForKey:@"gender"],@"gender",
                                                                    [[dictProfile valueForKey:@"location"] valueForKey:@"name"],@"location",
                                                                    [dictProfile valueForKey:@"timezone"],@"timezone",
                                                                    @"",@"language",
                                                                    [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=large",[dictProfile valueForKey:@"id"]],@"profile_pic_url",
                                                                    @"",@"cover_pic_url",nil];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];

    [manager POST:@"http://10.1.81.35:8000/api/login/" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

并作为回应我得到以下错误

Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo=0x7c87b6f0 {com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7cc220e0> { URL: …

我有一个字符串如下:

NSString *str = @"abcd,efgh";

现在我想将此字符串转换为NSMutableArray之类的

NSMutableArray *arr = {abcd,efgh};

那怎么办呢？

任何帮助,将不胜感激.

我已经编写了在instagram上传图像的代码,如下所示:

CGRect rect = CGRectMake(20 ,20 , 200, 200);
    UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
    [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIGraphicsEndImageContext();

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *jpgPath = [documentsDirectory stringByAppendingPathComponent:@"after2sm.ig"];

    NSString *fileURL = [NSString stringWithFormat:@"file://%@",jpgPath];
    NSURL *igImageHookFile = [NSURL fileURLWithPath:fileURL];

    self.dic.UTI = @"com.instagram.photo";

    self.dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
    self.dic=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];

    [NSDictionary dictionaryWithObject:@"My Caption" forKey:@"InstagramCaption"];
    [self.dic presentOpenInMenuFromRect:rect inView:self.view animated:YES];

但是它会打开一个带有"instagram"选项的动作表,但是当我点击它没有任何反应时,请你帮助我
