我目前正在用Xcode 6 (Beta 6)测试我的应用程序。UIActivityViewController在iPhone设备和模拟器上工作得很好，但在iPad模拟器和设备(iOS 8)上崩溃
Terminating app due to uncaught exception 'NSGenericException',
reason: 'UIPopoverPresentationController
(<_UIAlertControllerActionSheetRegularPresentationController: 0x7fc7a874bd90>)
should have a non-nil sourceView or barButtonItem set before the presentation occurs.
我使用以下代码用于iPhone和iPad的iOS 7以及iOS 8
NSData *myData = [NSData dataWithContentsOfFile:_filename];
NSArray *activityItems = [NSArray arrayWithObjects:myData, nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:nil applicationActivities:nil];
activityViewController.excludedActivityTypes = @[UIActivityTypeCopyToPasteboard];
[self presentViewController:activityViewController animated:YES completion:nil];
我得到一个类似的崩溃在我的另一个应用程序以及。你能引导我吗?ios8中的UIActivityViewController有什么变化吗?我查过了，但在这上面什么也没找到
迅速:
let activityViewController = UIActivityViewController(activityItems: sharingItems, applicationActivities: nil)
//if iPhone
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Phone) {
self.presentViewController(activityViewController, animated: true, completion: nil)
} else { //if iPad
// Change Rect to position Popover
var popoverCntlr = UIPopoverController(contentViewController: activityViewController)
popoverCntlr.presentPopoverFromRect(CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/4, 0, 0), inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
修复了Swift 2.0
if UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Phone {
self.presentViewController(activityVC, animated: true, completion: nil)
}
else {
let popup: UIPopoverController = UIPopoverController(contentViewController: activityVC)
popup.presentPopoverFromRect(CGRectMake(self.view.frame.size.width / 2, self.view.frame.size.height / 4, 0, 0), inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
SwiftUI版本
func presentActivityView(items: [Any]){
let activityController = UIActivityViewController(activityItems: items, applicationActivities: nil)
if UIDevice.current.userInterfaceIdiom == .pad{
activityController.popoverPresentationController?.sourceView = UIApplication.shared.windows.first
activityController.popoverPresentationController?.sourceRect = CGRect(x: UIScreen.main.bounds.width / 3, y: UIScreen.main.bounds.height / 1.5, width: 400, height: 400)
}
UIApplication.shared.windows.first?.rootViewController?.present(activityController, animated: true, completion: nil)
}
只是作为参考。
我分享以下代码，这一个使用Swift 5.0。此外，它还避免了弃用的窗口。
UIApplication.shared.windows.first ? .rootViewController !。present(actiycontroller, animated: true, completion: nil)
代码片段如下:
let activityController = UIActivityViewController(activityItems: [activityItem], applicationActivities: nil)
let scenes = UIApplication.shared.connectedScenes
let windowScene = scenes.first as? UIWindowScene
let window = windowScene?.windows.first
if UIDevice.current.userInterfaceIdiom == .pad{
activityController.popoverPresentationController?.sourceView = window
activityController.popoverPresentationController?.sourceRect = CGRect(x: UIScreen.main.bounds.width / 3, y: UIScreen.main.bounds.height / 1.5, width: 400, height: 400)
}
window?.rootViewController!.present(activityController, animated: true)
它已经在iPhone和iPad上进行了测试。
希望它能帮助到一些人。
干杯!
