iOS26闪退 #304

ESTabBar.swift中 “UITabBarButton”不在这个层级了 导致tabBarButtons为空
let tabBarButtons = subviews.filter { subview -> Bool in
if let cls = NSClassFromString("UITabBarButton") {
return subview.isKind(of: cls)
}
return false
} .sorted { (subview1, subview2) -> Bool in
return subview1.frame.origin.x < subview2.frame.origin.x
}
