swift - 如何快速共享图像和文本？

Question

我正在尝试快速共享图像和文本。但是当我选择通过 facebook、messenger 或 whatsapp 分享时，它只提供文字(不分享图片)。我正在使用 UIActivityViewController 进行共享。

这是我的代码:

func displayShareSheet(latitude:NSString?, longitude:NSString?, image:UIImage?, address:NSString? ) {
    let activityViewController = UIActivityViewController(activityItems: [(latitude as NSString?)!, (longitude as NSString?)!, (image as UIImage?)!, (address as NSString?)!], applicationActivities: nil)
    presentViewController(activityViewController, animated: true, completion: {}
)
}

下面是为我工作的 UIActivityViewController 代码。还附上了这两种方法的屏幕截图。

 func shareImage() {
            let img = UIImage(named: "SoSampleImage")
            let messageStr = "Ketan SO"
            let activityViewController:UIActivityViewController = UIActivityViewController(activityItems:  [img!, messageStr], applicationActivities: nil)
            activityViewController.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]
            self.presentViewController(activityViewController, animated: true, completion: nil)
        }

使用 SLComposeViewController 的替代方法:

func share(){
        let img = UIImage(named: "SoSampleImage")
        let composeSheet = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
        composeSheet.setInitialText("Hello, Ketan!")
        composeSheet.addImage(img)
        self.presentViewController(composeSheet, animated: true, completion: nil)
    }
