如何在iOS5之前在Twitter上發送圖像

Question

我正在創建一個與Twitter集成的應用程序。我想知道創建按鈕以在推特中添加設備圖像的方法，還想知道在哪個框架中使用它。代碼，因為我的應用程序也應與ios4兼容。

首先，可以在iOS5之前的Twitter上發送圖像嗎？

Answer 1

使用sharekit 。 請參閱ShareKit鏈接。

Answer 2

1. 是的，您可以將圖像上傳到Twitter。
2. 看看這篇關於將Twitter集成到您的應用程序中的博客文章； 和
3. 這是關於將twitpic添加到您的應用程序以上傳圖像

Answer 3

您可以使用Oauth進行此發送。它與ios4兼容.acct123是Oauth帳戶

- (IBAction)composeTweet:(id)sender
{
   // Build a twitter request
NSString *resultprofileUrl= [NSString stringWithFormat:@"https://api.twitter.com/1/statuses/update.json"];

tweets = [NSMutableArray array];


// Posting image and text to twitpic............


ASIFormDataRequest *req = [[ASIFormDataRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.twitpic.com/2/upload.json"]];
[req addRequestHeader:@"X-Auth-Service-Provider" value:@"https://api.twitter.com/1/account/verify_credentials.json"];

[req addRequestHeader:@"X-Verify-Credentials-Authorization"
                value:[acct123 oAuthHeaderForMethod:@"GET"

                                          andParams:nil]];

[req setData:UIImageJPEGRepresentation(imageview3.image, 0.8) forKey:@"media"];

    [self refresh];
