iphone - UIWebView，启用触摸保存图像，就像在移动 Safari 中一样

Question

当用户在我的应用程序的 UIWebView 中按住图像时，我想启用保存图像和复制。是否有一个属性可以启用此功能，或者我是否需要编写一些特殊方法来完成此操作？

感谢阅读!

Answer 1

UIImage * downloadImage = [[UIImage alloc] initWithContentsOfFile:path];
    UIImageWriteToSavedPhotosAlbum(downloadImage,nil, nil, nil);
    [downloadImage release];

    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Saved" message:@"Wallpaper saved to your Gallery." delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil, nil];

    [alert show];
    [alert release];

Add this whole code to your long press method, it will save your image in gallery.
