我正在使用Google Analytics for Mobile Apps iOS SDK v3。屏幕跟踪工作正常,但我无法让事件跟踪工作。Xcode 显示错误:
No known class method for selector 'createEventWithCategory:withAction:withLabel:withValue:'
我的代码是:
- (IBAction)callButton:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:12345"]];
id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"ui_action"
withAction:@"button_press"
withLabel:@"play_button"
withValue:nil] build]];
}
