iPhone 应用程序中的 UIApplicationDelegate 从未调用回复 [英] The UIApplicationDelegate in the iPhone App never called reply

问题描述

我正在尝试使用以下代码从手表模拟器启动我的 iPhone 应用程序:

I am trying to launch my iPhone app from watch simulator using the below code :

WKInterfaceController 子类

[WKInterfaceController openParentApplication:[NSDictionary dictionaryWithObject:@"red" forKey:@"color"] reply:^(NSDictionary *replyInfo, NSError *error) {
NSLog(@"replyInfo %@",replyInfo);
NSLog(@"Error: %@",error);
}];

AppDelegate.m

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo))reply
{
NSLog(@"appdelegate handleWatchKitExtensionRequest");
NSLog(@"NSDictionary: %@",userInfo);
NSLog(@"replyInfo: %@",replyInfo);
}

我得到的错误是:

错误:错误域=com.apple.watchkit.errors 代码=2iPhone 应用程序中的 UIApplicationDelegate 从未在-[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]"UserInfo=0x7f8603227730 {NSLocalizedDescription=iPhone 应用程序中的 UIApplicationDelegate 从未在-[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]}

推荐答案

你需要调用reply block，即使你返回nil.以下将解决您的错误:

You need to call the reply block, even if you return nil. The following will resolve your error:

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo))reply
{
NSLog(@"appdelegate handleWatchKitExtensionRequest");
NSLog(@"NSDictionary: %@",userInfo);
NSLog(@"replyInfo: %@",replyInfo);
reply(nil);
}

参见 Apple 文档 了解更多信息.您还可以返回 NSDictionary reply(myNSDictionary); 包含返回到 Watchkit 扩展有用的任何信息，尽管字典只能包含可以序列化到属性列表文件的信息，所以例如，您可以传递字符串，但不能只传递包含对自定义类实例的引用的字典，而不先将它们打包为 NSData.

See the Apple documentation for further information. You can also return an NSDictionary reply(myNSDictionary); with whatever information it would be useful to return to your Watchkit extension, although the dictionary can only contain information that can be serializable to a property list file, so for instance you can pass strings but you can't just pass a dictionary containing references to instances of your custom classes without packaging them up as NSData first.
