我在iOS中单元测试异步调用时遇到问题.(虽然它在视图控制器中工作正常.)

以前有人遇到过这个问题吗？我尝试过使用等待功能,但我仍然遇到同样的问题.

请提供一个很好的方法来举例说明.

UIActivityViewController setCompletionWithItemsHandler未调用whatsapp活动.

有没有人遇到同样的问题？请分享解决方案.

NSArray *applicationActivities = @[[[JBWhatsAppActivity alloc] init]];

UIActivityViewController* activityViewController = nil;
if(installed)
    activityViewController = [[UIActivityViewController alloc] initWithActivityItems:dataToShare applicationActivities:nil];
else
    activityViewController = [[UIActivityViewController alloc] initWithActivityItems:dataToShare applicationActivities:applicationActivities];

// Setting subject field while sharing app with email
[activityViewController setValue:@"Check out this Site !" forKey:@"subject"];

NSArray *excludedActivities = @[UIActivityTypePostToWeibo,
                                UIActivityTypePrint,
                                UIActivityTypeCopyToPasteboard,
                                UIActivityTypeAssignToContact,
                                UIActivityTypeSaveToCameraRoll,
                                UIActivityTypeAddToReadingList,
                                UIActivityTypePostToFlickr,
                                UIActivityTypePostToVimeo,
                                UIActivityTypePostToTencentWeibo,
                                UIActivityTypeAirDrop
                                ];
activityViewController.excludedActivityTypes = excludedActivities;



[activityViewController setCompletionWithItemsHandler:^(NSString * __nullable activityType, BOOL completed, NSArray * __nullable returnedItems, NSError * __nullable activityError)
 {

 }
 ];


[self presentViewController:activityViewController …

嗨我的代码在xcode中运行完美 7.x.x

一旦我更新了我的xcode,我就会遇到这个问题,请给我解决方案.

细节 :

使dyld:找不到符号:从_kABPersonAddressCityKey引用:在/var/containers/Bundle/Application/0A16B18D-CB72-4FCA-94F7-422AFD1411AD/ABCD.app/ABCD预计:/System/Library/Frameworks/PassKit.framework/PassKit在/var/containers/Bundle/Application/0A16B18D-CB72-4FCA-94F7-422AFD1411AD/ABCD.app/ABCD

https://docs.swift.org/swift-book/LanguageGuide/StringsAndCharacters.html说：

\n

如果两个字符串值（或两个字符值）的扩展字素簇在规范上等效，则认为它们相等。如果扩展字素簇具有相同的语言含义和外观，则它们在规范上是等效的，即使它们在幕后由不同的 Unicode 标量组成。

\n

扩展字素簇是什么意思？
