I need some help filtering an array of Structs.
This is what I am doing currently, it filters the array but not correctly. For example lets say I search for an item in the array with "Mid" I have one item that should be shown however the item shown starts with "Bad".
var array = breweries.filter() { $0.name?.lowercaseString.rangeOfString(searchController.searchBar.text.lowercaseString) != nil }
results = array
here is my Struct
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
}
}
Please point in the right direction!
Note: I am using Swift 1.2
Update:
I thought a video would be of help to better explain what I am trying to do.
Demo Of issue
What I want is to find the filter the array so only the item with a similar name is shown.
Update 2: As it turns out I forgot to handle the case when my UISearchController was active.
Assuming your Struct
name is Breweries
and it has a name
property, try this:
let array = breweries.filter() {
($0.name!.lowercaseString as NSString).containsString(searchController.searchBar.text.lowercaseString)
}
Your usage of filter is correct, but your closure seem to be complicated with no clear goal. I suggest you to write an extension (or possibly use what I am using):
extension String {
func contains(search: String, ignoreCase: Bool = false, ignoreDiacritic: Bool = false) -> Bool {
var options = NSStringCompareOptions.allZeros
if ignoreCase { options |= NSStringCompareOptions.CaseInsensitiveSearch }
if ignoreDiacritic { options |= NSStringCompareOptions.DiacriticInsensitiveSearch }
return self.rangeOfString(search, options: options) != nil
}
}
This way you can use closure like this to search:
breweries.filter() {
$0.name?.contains("x") // Precise search
$0.name?.contains("x", ignoreCase: true, ignoreDiacritics: true) // Ignores diacritics and lower / upper case
}
of course, you can use | or & to search for multiple parameters
breweries.filter() {
$0.name?.contains("x") || $0.streetAddress?.contains("x")
}
Hope it helps!
