实现快速查看QLPreviewController动画

Question

我正在尝试实现QLPreviewControllerDelegate的以下方法，该方法要求我返回在预览控制器之前显示我的预览项的视图;这应该是self.view但是我得到以下编译错误：

Automatic Reference Counting Issue: Implicit conversion of an Objective-C pointer to 'UIView *__autoreleasing *' is disallowed with ARC

如何解决此问题？

//Called when a Quick Look preview is about to be presented full screen or dismissed, to     provide a zoom effect.

- (CGRect)previewController:(QLPreviewController *)controller frameForPreviewItem:(id <QLPreviewItem>)item inSourceView:(UIView **)view
{

    // Set the source view  
    view = self.view;

    // Set the Rectangle of the Icon
    return self.view.bounds; 
}

Answer 1

view参数是指向视图的指针。要设置它，您将使用以下语法：

*view = self.view;
