分享facebook.分享instagram其他代码

分享到instagram.一般只能分享图片.但是需要分享视频文件.就将数据加载到本地然后再分享出去.视频有长度限制60s以内才行
-(void)instaGramWallPostWithURL:(NSString *)url { NSURL *myURL = [NSURL URLWithString:@"一个视频url"]; NSData * imageData = [[NSData alloc] initWithContentsOfURL:myURL]; // UIImage *imgShare = [[UIImage alloc] initWithData:imageData]; NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"]; if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not { // UIImage *imageToUse = imgShare; NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; // NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"Image.igo"]; NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"Video.mp4"]; // NSData *imageData=UIImagePNGRepresentation(imageToUse); [imageData writeToFile:saveImagePath atomically:YES]; NSURL *imageURL=[NSURL fileURLWithPath:saveImagePath]; self.documentController=[[UIDocumentInteractionController alloc]init]; self.documentController = [UIDocumentInteractionController interactionControllerWithURL:imageURL]; self.documentController.delegate = self; self.documentController.annotation = [NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"Testing"], @"InstagramCaption", nil]; self.documentController.UTI = @"com.instagram.exclusivegram"; UIViewController *vc = [UIApplication sharedApplication].keyWindow.rootViewController; [self.documentController presentOpenInMenuFromRect:CGRectMake(1, 1, 1, 1) inView:vc.view animated:YES]; } else { NSLog(@"Instagram not found"); } }
