我为iPhone制作了一个应用程序.现在,我正在为iPad重新创建它.

当用户选择工具栏中的操作按钮时,弹出窗口应显示a UIActivityViewController,但由于某种原因,它需要大约10秒才能显示第一次.在iPhone上,它需要大约一秒钟.除了弹出框之外,它是相同的代码.

我尝试禁用弹出窗口,但仍需要大约10秒才能显示.

这是代码:

-(IBAction)Actions:(UIBarButtonItem*)sender 
{
    if ([activityPopover isPopoverVisible] == YES) 
    {
        [activityPopover dismissPopoverAnimated:YES];
        return;
    }
    UIWebView *currentWebView = ((TabView *)self.tabs[self.currentTabIndex]).webViewObject;

    NSString *currentURL = (NSString*)[currentWebView request].mainDocumentURL;
    if (currentURL == NULL) return;

    BookmarkActivity *bookmarkActivity = [[BookmarkActivity alloc] init];

    UIActivityViewController *sharing = [[UIActivityViewController alloc] initWithActivityItems:[NSArray arrayWithObject:currentURL] applicationActivities:@[bookmarkActivity]];

    activityPopover = [[UIPopoverController alloc] initWithContentViewController:sharing];
    [activityPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];    
}

我已经在我的iPad 3和我的iPad mini上进行了测试,两者都需要一段时间来呈现.

我该如何解决这个问题？

当我使用a时UIActivityViewController,在用户选择活动(例如Mail或Message)后,我无法更改状态栏的文本颜色,也无法更改"取消"和"发送"导航栏按钮的文本/色调颜色.对于条形按钮,在AppDelegate我尝试过使用:

    [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

没有任何反应.但是我可以用这个设置导航栏标题:

    [[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor, nil]];

我设置UIViewControllerBasedStatusBarAppearance到NO中Info.plist.并把线:

    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

在AppDelegate,并没有运气改变状态栏颜色.有任何想法吗？

我的iOS是8.1.2,我正在使用UIActivityViewController进行社交分享.我点击一个按钮,让UIActivityViewController出现

- (IBAction)UIActivityTypeButtonClick:(id)sender {

NSString* text=@"I am sharing this text";
NSArray* sharedArray=@[text];
UIActivityViewController * activityVC=[[UIActivityViewController alloc]initWithActivityItems:sharedArray applicationActivities:nil];
activityVC.excludedActivityTypes=@[];
[self presentViewController:activityVC animated:YES completion:nil];
}

我得到了这个

我收到消息,Twitter,邮件,WhatsApp和更多按钮.
单击更多我得到这个.

FACEBOOK 在哪里.我在我的iPhone上有facebook应用程序,并且在设置中也设置了我的ID.但Facebook永远不会出现在这里.Twitter确实如此.这是一个错误还是什么？请建议

谢谢

我正在尝试UIActivityViewController从 SwiftUI 视图中呈现（共享表）。我创建了一个名为ShareSheetconformed to的视图UIViewControllerRepresentable来配置UIActivityViewController.

struct ShareSheet: UIViewControllerRepresentable {
    typealias UIViewControllerType = UIActivityViewController

    var sharing: [Any]

    func makeUIViewController(context: UIViewControllerRepresentableContext<ShareSheet>) -> UIActivityViewController {
        UIActivityViewController(activityItems: sharing, applicationActivities: nil)
    }

    func updateUIViewController(_ uiViewController: UIActivityViewController, context: UIViewControllerRepresentableContext<ShareSheet>) {

    }
}

通过天真​​地这样做.sheet会导致以下情况。

.sheet(isPresented: $showShareSheet) {
    ShareSheet(sharing: [URL(string: "https://example.com")!])
}

有没有办法像通常呈现的那样呈现这个？比如覆盖一半的屏幕？

我有保存在Documents目录中的jpg文件,可以从标准UIActivityViewController共享.所有活动项目(包括"保存图像")都按预期工作,但是当点击"保存图像"时,控制台中会显示以下错误,尽管事实上jpg确实已保存到相机胶卷.

这是iOS中的错误,还是我必须以某种方式指定我的文件是文件URL中的jpg(而不是视频)？

2015-07-29 06:46:58.317 AppName [4658:893408]视频/var/mobile/Containers/Data/Application/A63DF08E-21D0-435D-A0D7-84D73D632FC9/Documents/ImageStore/805/23.jpg无法保存到保存的相册:错误域= AVFoundationErrorDomain代码= -11828"无法打开"UserInfo = 0x1702e8b80 {NSLocalizedFailureReason =不支持此媒体格式.,NSLocalizedDescription =无法打开,NSURL = file:/// var/mobile/Containers /数据/应用/ A63DF08E-21D0-435D-A0D7-84D73D632FC9/Documents/ImageStore/805/23.jpg,NSUnderlyingError = 0x170c4f9f0"操作无法完成.(OSStatus error -12847.)"}

这是我正在使用的代码:

NSURL *fileURL = [NSURL fileURLWithPath: [...path to my file...] isDirectory:NO];
UIActivityViewController *activityViewController = [[UIActivityViewController    alloc] initWithActivityItems:@[fileURL] applicationActivities:nil];
activityViewController.excludedActivityTypes = @[UIActivityTypeCopyToPasteboard, UIActivityTypePrint, UIActivityTypeAssignToContact, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo];
[self presentViewController:activityViewController animated:YES completion:nil];

我喜欢将自己的WhatsApp添加ActivityItem到UIActivityViewController,但它总是添加到较低的非彩色活动栏,但我喜欢将它添加到上部栏,带有彩色项目的栏.

那是我使用的代码:

WhatsApp *whatsApp = [[WhatsApp alloc] init];
            UIActivityViewController* activityVC = [[UIActivityViewController alloc] initWithActivityItems:@[image, text] applicationActivities:@[whatsApp]];

喜欢.

我正在使用UIActivityViewController来共享图像.Facebook最近发生变化后.我可以单独分享图像和Url,但我无法同时共享图像和网址.相同的代码适用于Mail,twitter等.不确定我在Facebook上缺少什么.

func shareImage() {
    var myWebsite = NSURL(string:"http://www.google.com/")
    var img: UIImage = currentPhoto!
    var shareItems:Array = [img, myWebsite]
    let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    activityViewController.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]
    self.presentViewController(activityViewController, animated: true, completion: nil)

}

我试图在swift中分享图像和文本.但是当我选择通过facebook,messenger或whatsapp进行分享时,它只提供文本(图像不共享).我正在使用UIActivityViewController进行共享.

这是我的代码:

func displayShareSheet(latitude:NSString?, longitude:NSString?, image:UIImage?, address:NSString? ) {
    let activityViewController = UIActivityViewController(activityItems: [(latitude as NSString?)!, (longitude as NSString?)!, (image as UIImage?)!, (address as NSString?)!], applicationActivities: nil)
    presentViewController(activityViewController, animated: true, completion: {}
)
}

我正在使用UIActivityViewController来共享文章网址,使用下面的代码,

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:shareItemArray applicationActivities:nil];

activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, UIActivityTypeAirDrop]; 

[self presentViewController:activityVC animated:YES completion:nil];

上面的代码在iOS 9和10中工作,但它在iOS 11中不起作用

我调试它,代码执行正常,之后我在控制台中收到错误日志,如下所示

[ShareSheet]错误:等待建立与ShareUI视图服务扩展的连接超时.

有没有人面临这个问题？有解决方法吗？

编辑:清理并运行项目后,我尝试做同样的事情,在UIActivityViewController打开2或3次后,我再次尝试,第一次我得到相同的上述错误,第二次只有UIActivityViewController被打开.

I'm trying to implement “Save image to Library” function and then return back to the current view controller, but on a new iOS 13 it dismisses back to the view controller that presented the current one:

PHPhotoLibrary.requestAuthorization({(_ status: PHAuthorizationStatus) -> Void in })

let shareItems: Array = [newImg,"Hello"] as [Any]

let activityController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)

if UIDevice.current.userInterfaceIdiom == .pad {
    activityController.popoverPresentationController?.sourceView = saveButton
}

present(activityController, animated: true)
