iOS轻薄亚麻背景？ [英] iOS light linen background?

问题描述

我真的想知道是否有办法获得iOS的轻薄亚麻背景。这是它的样子：

I really want to know if there's a way to get iOS's light linen background. Here's what it looks like:

有没有办法只使用内置的SDK来访问它？或者我必须在某个地方找到这样的图像？

Is there a way to access this by merely using the built-in SDK? Or do I have to find an image like this somewhere?

编辑：我没有'我想使用私有API，所以这就是我所做的。我以这种方式抓取图像：

I didn't want to use private APIs, so here's what I did. I grabbed the image this way:

CGRect rect = CGRectMake(0.0f, 0.0f, 640.0f, 960.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [[UIColor underPageBackgroundColor] CGColor]);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagepath = [documentsDirectory stringByAppendingPathComponent:@"underPageBackground.png"];
[UIImagePNGRepresentation(image) writeToFile:imagepath atomically:YES];

希望这对某人有用。 ：）
