本文介绍了此解码器将仅解码采用NSSecureCoding的类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在AppDelegate中，我称之为:
From AppDelegate i call this:
-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply{
[SavedSearchesHack getAllMatches:^(MatchCollection * _Nonnull matchCollection) {
reply(@{@"response" : matchCollection});
}];
}
然后我在调用回复时收到此错误:
And then i get this error when calling the reply:
***由于未捕获的异常'NSInvalidUnarchiveOperationException'而终止应用程序，原因:'此解码器仅解码采用NSSecureCoding的类.类'Test.MatchCollection'不采用它.'
*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'This decoder will only decode classes that adopt NSSecureCoding. Class 'Test.MatchCollection' does not adopt it.'
public class func openParentApplication(userInfo: [NSObject : AnyObject],
reply: (([NSObject : AnyObject], NSError?) -> Void)?) -> Bool
只要我只返回"test"之类的对象而不是MatchCollection，我就不会出错.
As long as i return simply objects like "test" instead of a MatchCollection i get no error.
推荐答案
添加到 .h 文件
// just the protocol
@interface PacketH: NSObject<NSSecureCoding>
添加 .m 文件
+ (BOOL)supportsSecureCoding {
return YES;
}
