Question

将照片发布到Instagram时，没有显示标题，它只是空的。

Instagram已禁用此功能吗？如果不是，我的代码可能不正确。

以下是我尝试过的方法：

-(void)shareImageOnInstagram:(UIImage *)image
{
    //Must be 612x612
    NSString* imagePath = [NSString stringWithFormat:@"%@/instagramShare.igo", [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]];
    [[NSFileManager defaultManager] removeItemAtPath:imagePath error:nil];

    UIImage *instagramImage = image;
    [UIImagePNGRepresentation(instagramImage) writeToFile:imagePath atomically:YES];
    NSLog(@"Image Size >>> %@", NSStringFromCGSize(instagramImage.size));

    self.docController.annotation = [NSDictionary dictionaryWithObject:@"mmm" forKey:@"InstagramCaption"];

    self.docController=[UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:imagePath]];
    self.docController.delegate = self;
    self.docController.UTI = @"com.instagram.exclusivegram";
    [self.docController presentOpenInMenuFromRect: self.view.frame inView:self.view animated:YES ];
}

谢谢！

您在尝试设置注释后初始化了UIDocumentInteractionController。你必须切换这两行，如下所示：

self.docController=[UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:imagePath]];

self.docController.annotation = [NSDictionary dictionaryWithObject:@"Posted using #Truthly" forKey:@"InstagramCaption"];
self.docController.delegate = self;
self.docController.UTI = @"com.instagram.exclusivegram";
[self.docController presentOpenInMenuFromRect: self.view.frame inView:self.view animated:YES ];

发布到Instagram时不起作用的标题
