ios - 保存包括条形图在内的完整屏幕截图

Question

我在使用以下代码时遇到问题，只拍摄了我的 UITableView 的照片，而不是整个屏幕的导航栏和标签栏...

我想要全屏捕获，包括导航和标签栏。非常感谢任何帮助。

- (UIImage*)captureView:(UIView *)view
{
CGRect rect = [[UIScreen mainScreen] bounds];
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
[view.layer renderInContext:context];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return img;
}

following代码几个月前对我有用:

CALayer *layer = [[UIApplication sharedApplication] keyWindow].layer;
CGFloat scale = [UIScreen mainScreen].scale;
UIGraphicsBeginImageContextWithOptions(layer.frame.size, NO, scale);

[layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext();
