我正在使用 Xamarin 表单,并且在我的应用程序中有一个按钮来分享我的 android 应用程序中存在的问题,我使用 Intent 进行了处理,但在我的应用程序中,ios 不知道该怎么做,有人可以帮助我?
使用安卓
public async Task<bool> Share(ImageSource image)
{
Intent shareIntent = new Intent(Intent.ActionSend);
bitmapToShare = await GetBitmap (image);
if (bitmapToShare != null) {
CreateDirectoryForPictures("Xpto");
var filePath = System.IO.Path.Combine (dir.AbsolutePath, string.Format("xpto_{0}.png",Guid.NewGuid()));
var stream = new FileStream (filePath, FileMode.Create);
bitmapToShare.Compress (Bitmap.CompressFormat.Png, 100, stream);
stream.Close ();
Java.IO.File file = new Java.IO.File (filePath);
shareIntent.SetType ("image/*");
shareIntent.PutExtra (Intent.ExtraStream, Android.Net.Uri.FromFile (file));
shareIntent.AddFlags (ActivityFlags.GrantReadUriPermission);
Forms.Context.StartActivity (Intent.CreateChooser (shareIntent, "Compartilhar"));
}
return true;
}
private static async Task ShareImageAsyc(ImageSource image, string message, string url = null)
{
var handler = image.GetHandler();
if (handler == null) return;
var uiImage = await handler.LoadImageAsync(image);
var items = new List<NSObject> { new NSString(message ?? string.Empty) };
if (!url.IsNullOrEmpty())
items.Add(new NSString(url));
items.Add(uiImage);
var controller = new UIActivityViewController(items.ToArray(), null);
UIApplication.SharedApplication.KeyWindow.RootViewController.GetTopViewController()
.PresentViewController(controller, true, null);
}
