Question

当uibutton调用时，在使用subscribe方法时应用程序崩溃，并在堆栈中给出以下错误。

   ncaught exception: +[NSDate act_secondsSince1970]: unrecognized selector sent to class 0x10dd06e08

App崩溃了。见下文：

    [[_loginButton rac_signalForControlEvents:UIControlEventTouchUpInside]
 subscribeNext:^(id x) {
     [[MBAnalyticsHTTPClient sharedClient] capture:[AnalyticsModel initWithContext:@"welcome_to_mamabear" action:@"log_in_as_guardian"]];
}];
