主要代码下面2行
UIImage * saveimg=[self saveImage];
UIImageWriteToSavedPhotosAlbum(saveimg, self, @selector(savedPhotoImage:didFinishSavingWithError:contextInfo:), nil);
-(UIImage*)saveImage{
UIGraphicsBeginImageContext(CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height - 20));//保存self.view上的内容
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return viewImage;
}
