我已经完成了这样的代码,但是它打开了QLPreviewController但是 共享按钮未被禁用。我尝试了不同的东西,但它已经尝试过了 没工作。
- 或者你可以建议我任何不同的预览控制器,我可以在其中禁用分享按钮。
qlViewController = QLPreviewController()
qlViewController.navigationItem.rightBarButtonItem = nil
func numberOfPreviewItemsInPreviewController(controller:QLPreviewController) - > Int { 返回1 }
func previewController(controller: QLPreviewController, previewItemAtIndex index: Int) -> QLPreviewItem {
controller.navigationItem.rightBarButtonItem = nil
return fileUrlToOpen
}
答案 0 :(得分:0)
有一个示例如何隐藏右侧分享按钮
final class AttachmentQuickLookVC: QLPreviewController {
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
self.navigationItem.rightBarButtonItems = [UIBarButtonItem]()
}
}
此外,如果你想自定义后退按钮,你可以做这样的事情:
final class AttachmentQuickLookVC: QLPreviewController {
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
let backButton = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 35))
backButton.contentEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
backButton.contentHorizontalAlignment = .left
backButton.setImage(UIImage(named: "ic_back"), for: .normal)
let barButton = UIBarButtonItem(customView: backButton)
self.navigationItem.leftBarButtonItems = [barButton]
self.navigationItem.hidesBackButton = true
}
}
