我可以使用相同的方式共享图像
SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL parameters:message];
if (isImage)
{
NSData *data = UIImagePNGRepresentation(imgSelected);
[postRequest addMultipartData:data withName:@"media" type:@"image/png" filename:@"Testimage.png"];
}
postRequest.account = account;
[postRequest performRequestWithHandler:^(NSData *responseData,NSHTTPURLResponse *urlResponse,NSError *error)
{
if (!error)
{
NSLog(@"Upload Sucess !");
}
}];
解决方法
Uploads using this endpoint require at least 3 calls,one to
initialize the request,which returns the media_id,one or more calls
to append/upload binary or base64 encoded data,and one last call to
finalize the upload and make the media_id usable with other resources.
它的工作原理如下：
>请求1：发送具有视频大小(以字节为单位)的init请求.这将返回我们必须在请求2和3中使用的媒体ID号.
>请求2：使用请求1中返回的媒体ID号上传视频数据.
>请求3：视频上传完成后,将“FINALIZE”请求发送回Twitter API.这让Twitter API知道视频文件的所有块都已完成上传.
注意Twitter API接受“块”中的视频上传.因此,如果您的视频文件很大,您可能希望将其拆分为多个文件,因此您必须多次重复“请求2”(不要忘记每次都增加“segment_index”数字).
我已经开始编写以下代码了.尝试一下并尝试一下.我稍后会更新我的答案以改进它.
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediawithInfo:(NSDictionary *)info {
// Assign the mediatype to a string
Nsstring *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
// Check the media type string so we can determine if its a video
if ([mediaType isEqualToString:@"public.movie"]) {
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *webData = [NSData dataWithContentsOfURL:videoURL];
// Get the size of the file in bytes.
Nsstring *yourPath = [Nsstring stringWithFormat:@"%",videoURL];
NSFileManager *man = [NSFileManager defaultManager];
NSDictionary *attrs = [man attributesOfItemAtPath:yourPath error: NULL];
UInt32 result = [attrs fileSize];
//[self tweetVideoStage1:webData :result];
[self tweetVideo:webData :result :1 :@"n/a"];
}
}
-(void)tweetVideo:(NSData *)videoData :(int)videoSize :(int)mode :(Nsstring *)mediaID {
NSURL *twitterVideo = [NSURL URLWithString:@"https://upload.twitter.com/1.1/media/upload.json"];
// Set the parameters for the first twitter video request.
NSDictionary *postDict;
if (mode == 1) {
postDict = @{@"command": @"INIT",@"total_bytes" : videoSize,@"media_type" : @"video/mp4"};
}
else if (mode == 2) {
postDict = @{@"command": @"APPEND",@"media_id" : mediaID,@"segment_index" : @"0",@"media" : videoData };
}
else if (mode == 3) {
postDict = @{@"command": @"FINALIZE",@"media_id" : mediaID };
}
SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL:twitterVideo parameters:postDict];
// Set the account and begin the request.
postRequest.account = account;
[postRequest performRequestWithHandler:^(NSData *responseData,NSError *error) {
if (!error) {
if (mode == 1) {
// Parse the returned data for the JSON string
// which contains the media upload ID.
NSMutableDictionary *returnedData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error]
Nsstring *tweetID = [Nsstring stringWithFormat:@"%@",[returnedData valueForKey:@"media_id_string"]];
[self tweetVideo:videoData :result :2 :tweetID];
}
else if (mode == 2) {
[self tweetVideo:videoData :result :3 :mediaID];
}
}
else {
NSLog(@"Error stage %d - %",mode,error);
}
}];
}
