在Facebook中分享我的应用程序的屏幕截图(cocos2D 3.0)
提问于 2015-05-20 23:00:10
我需要在Facebook中分享我的应用程序的屏幕截图(我使用的是Cocos2D 3.0)，但代码不起作用：
// For take Screenshot of App
-(UIImage *)capture
{
AppDelegate *_appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
// for retina-display
UIGraphicsBeginImageContextWithOptions(_appDelegate.window.bounds.size, NO, [UIScreen mainScreen].scale);
[_appDelegate.window drawViewHierarchyInRect:_appDelegate.window.bounds afterScreenUpdates:NO];
} else {
// non-retina-display
UIGraphicsBeginImageContext(_appDelegate.window.bounds.size);
[_appDelegate.window drawViewHierarchyInRect:_appDelegate.window.bounds afterScreenUpdates:NO];
}
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
-(void)btnSharedFacebookTapped:(id)sender
{
[self capture];
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = [self capture];
// photo.userGenerated = YES;
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = @[photo];
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self];
