以表单大小显示弹出视图
Showing a popupview in the form size
我目前正在尝试在触摸按钮时在屏幕上显示我在 xib 中创建的视图。我希望它以表单样式显示在屏幕中间。然而,在这一点上,我只是在担心展示位置之前一直试图让它显示出来。
这是我在 xib 中创建的视图
我已经为其分配并创建了“CallNowView”class,目前看起来就像这样。
import Foundation
import UIKit
class CallNowView: UIViewController{
@IBOutlet var btnCancel: UIButton!
@IBOutlet var btnCall: UIButton!
@IBAction func btnCall_pressed(_ sender: AnyObject) {
}
@IBAction func btnCancel_pressed(_ sender: AnyObject) {
}
}
我在希望 xib 显示的视图中尝试做的如下
@IBAction func btnRSRCall_pressed(_ sender: AnyObject) {
if (callNowView == nil)
{
callNowView = CallNowView(nibName: "CallNow", bundle: nil)
}
if(UIViewController.responds(to: #selector(getter: popoverPresentationController))){
callNowView.modalPresentationStyle = .formSheet
callNowView.popoverPresentationController?.sourceView = btnCall;
callNowView.popoverPresentationController?.sourceRect = btnCall.bounds;
callNowView.popoverPresentationController?.permittedArrowDirections = .any
}
else {
//no support ios7 device, either ipad or iphone
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.phone)
{
//present standard controller for ios7, iphone,
self.present(callNowView, animated: true, completion: nil)
}
else
{
//present s popupcontroller for ios7, ipad
let popover = UIPopoverController.init(contentViewController: callNowView)
popover.present(from: btnCall.bounds, in: btnCall, permittedArrowDirections: .any, animated: true)
}
}
}
当我 运行 代码在这一行崩溃 self.present(callNowView, animated: true, completion: nil)
并出现错误 terminating with uncaught exception of type NSException
我希望有人能帮我解决这个问题
在你的xib中,你应该将File's Owner的Class设置为CallNowView,因为CallNowView是UIViewController的子类。然后将 Filer 的所有者视图拖到 IB 视图。它应该看起来像下面的截图:
