某些应用在iOS 6中显示默认操作表,其中包含共享选项.
社交框架只有两个类,一个用于撰写,一个用于请求.
我发现的是关于使用SLComposeViewController为特定服务进行编写,在显示之前我必须手动查询服务是否可用.然后我还必须使用自己的图标创建自己的操作表.
这些应用程序如何在iOS 6中显示此默认共享选项操作表？或者他们是否使用开源框架？
我想让用户能够共享位置，但我不知道如何UIActivityViewController在 SwiftUI 中显示。
我的应用程序(仅限iOS 8)因尝试IAP时崩溃而被拒绝.我在AdHoc版本中尝试了几乎所有购买过程,但无法重现崩溃.查看审核小组附带的崩溃日志,我在最后一个异常回溯中看到了一个非常奇怪的堆栈跟踪.崩溃看起来涉及UIPopoverController,但是我的应用程序虽然是通用的,但不会在任何地方显式或隐式显示弹出窗口.有没有人知道什么可能触发导致此崩溃的活动？什么可能导致我的应用程序在审核小组仅查看时显示popovers？

我的代码:
UIActivityViewController *controller =
[[UIActivityViewController alloc]
initWithActivityItems:@[text, url, myImage]
applicationActivities:nil];
[self presentViewController:controller animated:YES completion:nil];
崩溃后,Xcode吐出:

我正在为iPad构建一篇文章阅读应用程序.我已经集成了社交共享功能,这意味着用户可以在Facebook和谷歌邮件上分享文章.我正在UIActivityViewController用于分享.
有一个条形按钮项,当用户点击打开UIActivityViewController时.我更新了Xcode 6当我在模拟器上运行它运行正常但我在iOS 7的真实设备(iPad)上运行,应用程序在点击栏按钮项时崩溃.这是我的代码:
- (IBAction)ysshareAction:(id)sender
{
NSURL *linkURL = [NSURL URLWithString:_DetailModal1[4]];//article url
NSMutableAttributedString *stringText = [[NSMutableAttributedString alloc] initWithString:_DetailModal1[0]];//_DetailModal1[0] contain article title////
[stringText addAttribute:NSLinkAttributeName value:linkURL range:NSMakeRange(0, stringText.length)];
NSArray * itemsArray = @[[NSString stringWithFormat:@"%@",_DetailModal1[0]], [NSURL URLWithString:_DetailModal1[4]]];
NSArray * applicationActivities = nil;
UIActivityViewController * AVC = [[UIActivityViewController alloc] initWithActivityItems:itemsArray applicationActivities:applicationActivities];
AVC.popoverPresentationController.sourceView = _webView;
[self presentViewController:AVC animated:YES completion:nil];
[AVC setCompletionHandler:^(NSString *act, BOOL done)
{
if([act isEqualToString:UIActivityTypeMail]) {
ServiceMsg = @"Mail sent!";
} else if([act isEqualToString:UIActivityTypePostToTwitter]) {
ServiceMsg = @"Article …objective-c ipad uipopovercontroller ios uiactivityviewcontroller
当在这个应用程序中在iPhone上调用UIActivityViewController时,它可以很好地工作,但是当在iPad上调用时,应用程序崩溃了.以下是我使用的代码:
func shareButtonPress() {
//when the share button is pressed, default share phrase is added, cropped image of highscore is added
var sharingItems = [AnyObject]()
var shareButtonHighscore = NSUserDefaults.standardUserDefaults().objectForKey("highscore") as Int!
sharingItems.append("Just hit \(shareButtonHighscore)! Beat it! #Swath")
UIGraphicsBeginImageContextWithOptions(UIScreen.mainScreen().bounds.size, false, 0);
self.view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
var image:UIImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
sharingItems.append(image)
let activityViewController = UIActivityViewController(activityItems: sharingItems, applicationActivities: nil)
var barButtonItem: UIBarButtonItem! = UIBarButtonItem()
activityViewController.excludedActivityTypes = [UIActivityTypeCopyToPasteboard,UIActivityTypeAirDrop,UIActivityTypeAddToReadingList,UIActivityTypeAssignToContact,UIActivityTypePostToTencentWeibo,UIActivityTypePostToVimeo,UIActivityTypePrint,UIActivityTypeSaveToCameraRoll,UIActivityTypePostToWeibo]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
正如您所看到的,我正在Swift中编程,在SpriteKit框架中,我不明白为什么应用程序崩溃.
我收到此错误:
Terminating app due to uncaught exception 'NSGenericException', reason: …呈现一个UIDocumentMenuViewController能够将文件加载到应用中的功能。在iPhone上可以使用，但在iPad上则不能。使用iOS9。知道有什么问题吗？

我不明白为什么错误消息指的是collectionView什么？我根本不使用collectionView。也许UIDocumentMenuViewController将其作为内部组件？
我正在尝试添加一个按钮，以便在 Twitter、Facebook 等中分享一些句子。它适用于所有 iPhone 型号，但模拟器在 iPad 上崩溃。
这是我的代码：
@IBAction func shareButton(sender: AnyObject) {
frase = labelFrases.text!
autor = labelAutores.text!
var myShare = "\(frase) - \(autor)"
let activityVC: UIActivityViewController = UIActivityViewController(activityItems: [myShare], applicationActivities: nil)
self.presentViewController(activityVC, animated: true, completion: nil)
这是错误：
由于未捕获的异常“NSGenericException”而终止应用程序，原因：“UIPopoverPresentationController (<_UIAlertControllerActionSheetRegularPresentationController: 0x7c0f9190>) 应该在演示发生之前设置一个非零的 sourceView 或 barButtonItem
我该如何解决？谢谢
