如何截屏 tableView 的所有内容?(所有内容 = 可见区域 + 不可见区域)
我试过这个:
UIGraphicsBeginImageContext(self.tableView.bounds.size);
[self.tableView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage* image1 = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
self.imageView.image = image1;
但它不起作用,我的意思是它只是屏幕截图可见区域:(
我解决了:))
这是代码:)
+ (UIImage *)captureView:(UIScrollView *)view inContentRect:(CGRect)rect{
UIImage* image = nil;
CGPoint savedContentOffset = view.contentOffset;
CGRect savedFrame = view.frame;
UIGraphicsBeginImageContextWithOptions(view.contentSize, 1, 0);
view.contentOffset = CGPointZero;
view.frame = CGRectMake(0, 0, view.contentSize.width, view.contentSize.height);
[view.layer renderInContext: UIGraphicsGetCurrentContext()];
image = UIGraphicsGetImageFromCurrentImageContext();
view.contentOffset = savedContentOffset;
view.frame = savedFrame;
UIGraphicsEndImageContext();
// after all of this, crop image to needed size
return [Utils cropImage:image toRect:rect];
}
