刪除或覆蓋iPad上UIPopoverController的UISearchDisplayController上的「清除按鈕」？

Question

在iPad中使用UISearchDisplayController和UISearchBar時，它將顯示在UIPopoverController中。我想重寫圖像上顯示的清除按鈕以進一步修復。如果這是不可能的，我怎樣才能刪除清除按鈕？

我這樣做一次..我用自定義按鈕進行自定義操作更換清除按鈕..請檢查此

UISearchBar *searchBar = yourSearchController.searchBar; 
UITextField *searchtextfield = [searchBar.subviews objectAtIndex:1]; 
UIButton *cButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
cButton.frame = CGRectMake(0, 0, 20 , 20); 
cButton.backgroundColor = [UIColor clearColor]; 
[cButton setImage:[UIImage newImageFromResource:@"yourButtonImage"] forState:UIControlStateNormal];//your button image. 
cButton.contentMode = UIViewContentModeScaleToFill; 
[cButton addTarget:self action:@selector(customButtonPressed) forControlEvents:UIControlEventTouchUpInside];//This is the custom event 
[searchtextfield setRightView:cButton]; 
[searchtextfield setRightViewMode:UITextFieldViewModeAlways]; 

好運。
