1. How to reproduce the problem.

    初始化CYLTabBarController时，使用：@{
                CYLTabBarItemTitle : title ?: @"",
                CYLTabBarItemImage : img ?: @"",
                CYLTabBarItemSelectedImage : selectedImg ?: @"",
            }方式设置过一次。由于业务需要，在某些时机使用：
    [[[self.tabBar].items objectAtIndex:index] setImage:img];
    [[[sel.tabBar].items objectAtIndex:index] setSelectedImage:selectedImg];方式重新设置一次。导致[bug]:- (void)tabBarController:(UITabBarController *)tabBarController didSelectControl:(UIControl *)control不回调。

2. Please help me in this way.

排查发现调用[[[self.tabBar].items objectAtIndex:index] setImage:img];
[[[sel.tabBar].items objectAtIndex:index] setSelectedImage:selectedImg];再调用[self.view setNeedsLayout];重新触发CYLTabBarController的viewDidLayoutSubviews方法，即重新走到 CYLTabBar *tabBar = (CYLTabBar *)self.tabBar;
// add callback for visiable control, included all plusButton.
[tabBar.cyl_visibleControls enumerateObjectsUsingBlock:^(UIControl * _Nonnull control, NSUInteger idx, BOOL * _Nonnull stop) {
//to avoid invoking didSelectControl twice, because plusChildViewControllerButtonClicked will invoke setSelectedIndex
if ([control cyl_isChildViewControllerPlusButton]) {
return;
}
SEL actin = @selector(didSelectControl:);
[control addTarget:self action:actin forControlEvents:UIControlEventTouchUpInside];
if (idx == self.selectedIndex) {
control.selected = YES;
}
}];逻辑，能解决[bug]:- (void)tabBarController:(UITabBarController *)tabBarController didSelectControl:(UIControl *)control不回调的问题。求问原因？
