为何RAC在tf框架的懒加载中TF_LAZYLOAD_OBJC_CUS无法被调用？

[Dast1Woop]

TF_LAZYLOAD_OBJC_CUS(UIButton, gBtn4HideSelf, ^(UIButton *ins){ [ins setTitle:@"显示自我" forState:UIControlStateNormal]; [ins setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

/** 下面方法不会被执行，即：rac不能在tf框架的懒加载中使用。 */

// [[ins rac_signalForControlEvents:UIControlEventTouchUpInside] subscribeNext:^(__kindof UIControl * _Nullable x) { // ins.selected = !ins.selected; // if(ins.selected){//正显示自我 // [self.view bringSubviewToFront:self.gV4PushPreview]; // [ins setTitle:@"隐藏自我" forState:UIControlStateSelected]; // }else{ // [self.view sendSubviewToBack:self.gV4PushPreview]; // [ins setTitle:@"显示自我" forState:UIControlStateSelected]; // } // }]; })
