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

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
