Question

我的UITableViewController中有一个UISearchController。我希望隐藏搜索栏，直到用户向下滚动。在旧的UISearchDisplayController中，我在viewDidLoad方法中有以下代码：

  var foodLoads = {
    orange: 6.7,
    apple: 5.6,
    banana: 12.7,
    grapes: 16.3,
    peach: 2.7,
    pear: 6.5,
    mango: 16.1,
    blueberries: 9.3,
    grapefruit: 1.7,
    strawberries: 3.5,
    tangerine: 3.1,
    watermelon: 8,
    duck: 0,
    beef: 0,
    chicken: 0,
    ham: 0,
    turkey: 0,
    elk: 0,
    pork: 0,
    fish: 0,
    eggs: 0,
    lamb: 0,
    applejuice: 11.8,
    cranberryjuice: 23.3,
    orangejuice: 14.4,
    carrotjuice: 8.6,
    lemonade: 24.3,
    hotchocolatemix: 10.2,
    tomatojuice: 3.5,
    chocolatemilk: 13.3,
    almondmilk: 0.02,
    soymilk: 4,
    wholewheatbread: 6.1,
    whitebread: 10.7,
    bagel: 30,
    waffle: 13.8,
    pancake: 5.3,
    croissant: 12.2,
    muffin: 28.8,
    englishmuffin: 21.3,
    doughnut: 15.2,
    oatmeal: 12.6,
    quinoa: 20.4,
    wholegrainbread: 7.1 
  }

$('.submit-items').on('click', function() {
    var type = $('.food-list .active li');
    var foodName = $(type).text();
    var value = foodLoads[foodName];
    $(type).parent().append('<p>' + value + '</p>');  

})

不幸的是，上面的代码不再适用于UISearchController。

刚刚弄明白了这个问题。以下是错误的，

newBounds.origin.y = newBounds.origin.y + self.searchBar.bounds.size.height;

应该是

newBounds.origin.y = newBounds.origin.y + self.searchController.searchBar.bounds.size.height;

而不是self.searchBar，它需要是self.searchController.searchBar

UISearchController隐藏搜索栏
