    UIGraphicsBeginImageContext(myView.frame.size);
    [myView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    NSData *data=UIImagePNGRepresentation(viewImage);
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *strPath = [documentsDirectory stringByAppendingPathComponent:@"myimage.png"];
    [data writeToFile:strPath atomically:YES];
