iOS 微博 OAuth2.0 分享 文字 + 图片 微博的方法

也是采用两种方法，先放出第一种方法

 //https://upload.api.weibo.com/2/statuses/upload.json

    //https://api.weibo.com/2/statuses/update.json

    

    NSUserDefaults *info = [NSUserDefaultsstandardUserDefaults];

    NSData *imageData = UIImagePNGRepresentation([UIImageimageNamed:@"auth_header.png"]);

    NSURL *url = [[NSURLalloc] initWithString:@"https://upload.api.weibo.com/2/statuses/upload.json"];

    ASIFormDataRequest *request = [[ASIFormDataRequestalloc] initWithURL:url];

    

    [request addPostValue:SINAAPPKEY forKey:@"source"];

    [request addPostValue:@"sina pic test"forKey:@"status"];

    [request setData:imageData withFileName:@"auth_header.png"andContentType:@"image/jpeg"forKey:@"pic"];

    [request addPostValue:@"0" forKey:@"lat"];

    [request addPostValue:@"0" forKey:@"long"];

    [request addPostValue:[selfDecrypt:PasswordKey :[info objectForKey:@"sina_access_token"]] forKey:@"access_token"];

    [request startSynchronous];

    NSString *resultString = [request responseString];

    NSDictionary *result = [resultString objectFromJSONString];

    NSLog(@"The dic is %@", result);

    

    [request release];

    [url release];

 

使用iOS SDK的方式没有成功，贴几个相关的链接，如果后面有需要再参考
