實現快速查看QLPreviewController動畫

Question

我想實現QLPreviewControllerDelegate的下列方法，並且該方法要求我在預覽控制器之前返回顯示我的預覽項目的視圖;這應該是self.view但是我收到以下編譯錯誤：

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

如何解決此問題？

//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參數是一個指向視圖的指針。要設置它，你可以使用下面的語法：

*view = self.view;
