Tab Bar item detects only longer click

I am using custom tab bar without controller. 在此处输入图片说明 Here is the code I use to detect when item is selected.

func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {
    switch(item.tag) {
    case 1:
        // do something
    case 2:
        // do something
    case 3:
        // do something
    default:
        return

    }
}

My problem is that I have to press a bit longer to select an item. It does not recognize simple click like button click. Anyone know how to solve it.

Thank you for any suggestion or idea.

I faced similar problem in UIScrollView or UITableView. If your tab bar is within any of these controls deselect property "delaysContentTouches" in interface builder
