arrays - Swift 1.2 按关键字过滤结构数组

Question

我需要一些帮助来过滤结构数组。

这就是我目前正在做的，它过滤了数组但不正确。例如，假设我在数组中搜索带有“Mid”的项目我有一个应该显示的项目但是显示的项目以“Bad”开头。

    var array = breweries.filter() { $0.name?.lowercaseString.rangeOfString(searchController.searchBar.text.lowercaseString) != nil }

    results = array

这是我的结构

struct Breweries {
    let name: String?
    let breweryId: String?
    let distance: Double?
    let largeIconURL: String?
    let streetAddress: String?
    let locality: String?
    let region: String?
    let phone: String?
    let website: String?

    init(brewDictionary: [String: AnyObject]) {

        name = brewDictionary["brewery"]?["name"] as? String
        breweryId = brewDictionary["breweryId"] as? String
        distance = brewDictionary["distance"] as? Double
        largeIconURL = brewDictionary["brewery"]?["images"]??.objectForKey("large") as? String
        streetAddress = brewDictionary["streetAddress"] as? String
        locality = brewDictionary["locality"] as? String
        region = brewDictionary["region"] as? String
        phone = brewDictionary["phone"] as? String
        website = brewDictionary["website"] as? String


    }
}

请指正方向!

注意:我使用的是 Swift 1.2

更新:

我认为视频有助于更好地解释我正在尝试做的事情。

Demo Of issue

我想要的是找到数组的过滤器，以便只显示具有相似名称的项目。

更新 2:事实证明，当我的 UISearchController 处于事件状态时，我忘记处理这种情况。

假设您的 Struct 名称是 Breweries 并且它有一个 name 属性，试试这个:

let array = breweries.filter() {
    ($0.name!.lowercaseString as NSString).containsString(searchController.searchBar.text.lowercaseString)
}
