Question

我试图复制/通过example from Google：

 id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];

// Set screen name on the tracker to be sent with all hits.
[tracker set:kGAIScreenName
       value:@"Home Screen"];

// Send a screen view for "Home Screen".
[tracker send:[GAIDictionaryBuilder createAppView]];

// This event will also be sent with &cd=Home%20Screen.
[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"UX"
                                                      action:@"touch"
                                                       label:@"menuButton"
                                                       value:nil] build]];

// Clear the screen name field when we're done.
[tracker set:kGAIScreenName
       value:nil];

Xcode告诉我：不兼容的指针类型发送＆＃39; GAIDictionaryBuilder *＆＃39;参数类型＆＃39; NSDictionnary *＆＃39;在第二行（[tracker send:[GAIDictionaryBuilder createAppView]];）

当我运行应用程序时，它崩溃了：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[GAIDictionaryBuilder objectForKeyedSubscript:]: unrecognized selector sent to instance 0x16060d70'

Answer 1

您是否已将必要的GA SDK导入项目（通过Cocoapods或手动）
您是否在此特定课程中导入了GAI标题？
您的屏幕视图跟踪代码似乎不完整。
您的事件跟踪代码看起来合法。
祝你好运

我今天发生了这件事，结果却是我忽略了那条线的构建部分的问题。

您有2条GAIDictionary行，只有一条使用构建。尝试将其更改为：

[tracker send:[[GAIDictionaryBuilder createAppView] build]];

这对我有用。
