我有以下用于在 Instagram 上分享文章的代码。
-(void) shareInstagram {
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not
{
UIImage *instaImage = mImg.image;
NSData *imageData = UIImagePNGRepresentation(instaImage); //convert image into .png format.
NSLog(@"imageData.leeee===%d", imageData.length);
if (imageData.length<=100) {
[self.view makeToast:localize(@"instaErr2") duration:2.0 position:@"bottom"];
} else {
NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it
NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"insta.igo"]]; //add our image to the path
[fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the path (image)
NSLog(@"image saved");
CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndImageContext();
NSString *fileNameToSave = [NSString stringWithFormat:@"Documents/insta.igo"];
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:fileNameToSave];
NSLog(@"jpg path %@",jpgPath);
NSString *newJpgPath = [NSString stringWithFormat:@"file://%@",jpgPath];
NSLog(@"with File path %@",newJpgPath);
NSURL *igImageHookFile = [[NSURL alloc]initFileURLWithPath:newJpgPath];
NSLog(@"url Path %@",igImageHookFile);
self.documentController.UTI = @"com.instagram.exclusivegram";
self.documentController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.documentController=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
NSString *globalString;
if ([[[NSUserDefaults standardUserDefaults] valueForKey:@"PoPinFrom"] isEqualToString:@"user"]) {
globalString = [NSString stringWithFormat:@"%@ @ %@\n\nhttp://egkw.com/ArticleDetail.aspx?id=%@\n\niPhone : %@\n\nAndroid : %@", [[productDetailsArray objectAtIndex:0] valueForKey:@"Title"], localize(@"appName"), [[productDetailsArray objectAtIndex:0] valueForKey:@"Id"], localize(@"appStoreLink"), localize(@"playStoreLink")];
} else {
globalString = [NSString stringWithFormat:@"%@ @ %@\n\nhttp://egkw.com/ArticleDetail.aspx?id=%@\n\niPhone : %@\n\nAndroid : %@", [[productDetailsArray objectAtIndex:0] valueForKey:@"Title"], localize(@"appName"), [[productDetailsArray objectAtIndex:0] valueForKey:@"Id"], localize(@"appStoreLink"), localize(@"playStoreLink")];
}
globalString = [NSString stringWithFormat:@"%@\n\n#EGKW", globalString];
NSLog(@"insta==globalString==%@", globalString);
self.documentController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:globalString, @"InstagramCaption", nil];
// self.documentController.annotation = [NSDictionary dictionaryWithObject:globalString forKey:@"InstagramCaption"];
[self.documentController presentOpenInMenuFromRect:rect inView: self.view animated:YES];
}
}
else
{
NSLog (@"Instagram not found");
DTAlertView *myAl = [DTAlertView alertViewWithTitle:localize(@"err001") message:localize(@"instaErr") delegate:nil cancelButtonTitle:localize(@"dismiss") positiveButtonTitle:nil];
[myAl setDismissAnimationWhenButtonClicked:DTAlertViewAnimationSlideTop];
[myAl showWithAnimation:DTAlertViewAnimationSlideBottom];
}
}
此代码之前运行良好。然而,当我注意到时,我发现 Instagram 中没有显示标题。经过研究我改变了
self.documentController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:globalString, @"InstagramCaption", nil];
到
self.documentController.annotation = [NSDictionary dictionaryWithObject:globalString forKey:@"InstagramCaption"];
但还是不行。
知道出了什么问题吗?
Instagram 是否像 Facebook 一样更改了任何政策?
最佳答案
关于ios - Instagram InstagramCaption 不工作,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/31915122/

正如Instagram官方文档所说 To include a pre-filled caption with your photo, you can set the annotation proper
