iPhone MapView保存到相册

Question

如何将MapView保存到PhotoAlbum，以便以后附加到在iPhone应用程序中创建的电子邮件中？

Answer 1

Try this:

UIGraphicsBeginImageContext(map.layer.bounds.size);
[map.layer renderInContext:UIGraphicxGetCurrentContext()];
UIImage *mapImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

And perhaps you should also double-check Google's licensing terms if they allow making and distributing screenshots of the maps.
