ios - 了解 handleWatchKitExtensionRequest
<p><p>我正在测试一些代码在 iPhone 应用上的执行。我遵循 Apple 建议的文档(不使用后台任务，仅使用 <strong>控制台日志</strong>)。但是我在控制台上没有得到任何东西(我想看到字符串“howdy”)。</p>
<p>这是因为我<strong>在模拟器上运行 WatchKit 扩展应用</strong>吗？还是我遗漏了什么？</p>
<hr/>
<p>苹果说:</p>
<blockquote>
<p>If you are using openParentApplication:reply:, make sure you create a
background task immediately upon entering
application:handleWatchKitExtensionRequest:reply:. This will make sure
that the iPhone app gets time in the background instead of being
suspended again. Additionally, wrap the call to endBackgroundTask: in
a dispatch_after of 2 seconds to ensure that the iPhone app has time
to send the reply before being suspended again.</p>
</blockquote>
<p>我在 WatchKit 扩展上的实现(链接到按钮的操作方法):</p>
<pre><code>- (IBAction)sendMessageToApp{
NSString *requestString = ; // This string is arbitrary, just must match here and at the iPhone side of the implementation.
NSDictionary *applicationData = [ initWithObjects:@ forKeys:@[@"theRequestString"]];
[WKInterfaceController openParentApplication:applicationData reply:^(NSDictionary *replyInfo, NSError *error) {
NSLog(@"\nReply info: %@\nError: %@",replyInfo, error);
}];
NSLog(@"sending message..");
}
</code></pre>
<p>我在 <strong>AppDelegate.m</strong> 文件上的实现:</p>
<pre><code>- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo))reply {
NSString * request = ;
NSLog(@"howdy");
// This is just an example of what you could return. The one requirement is
// you do have to execute the reply block, even if it is just to 'reply(nil)'.
// All of the objects in the dictionary .
// If necessary, you can covert other objects to NSData blobs first.
NSArray * objects = [ initWithObjects:,,, , nil];
NSArray * keys = [ initWithObjects:@"objectAName", @"objectdName", @"objectBName", @"objectCName", nil];
NSDictionary * replyContent = [ initWithObjects:objects forKeys:keys];
reply(replyContent);
}
</code></pre>
<p>我在控制台中得到了什么:</p>
<pre><code>2015-04-16 14:43:44.034 FanLink WatchKit Extension <InterfaceController: 0x608000081fe0> initWithContext

objectCName = "2015-04-16 13:44:04 +0000";
objectdName = "2015-04-16 13:44:04 +0000";
}
Error: (null)

<p><p>这是因为您只是在调试 WatchKit 扩展目标。如果您还想在控制台中查看主应用程序日志，则需要通过 Xcode 调试器附加主应用程序的进程。
转到调试-->附加一个进程-->(然后按标识符选择并输入您的应用程序名称)</p>
