如何从nsarray的nsarray搜索特定联系人

Question

I have store the contact in alphabetical order so I have array of array for contact list which i have display on screen. Now i want to search the contact via name but predicate not work properly here. I have done below code.

   filterArray.filterUsingPredicate(NSPredicate(format: "ANY SELF.name CONTAINS[cd] '\(tfSearchBar.text!)'", argumentArray: nil))

In filter array first i have all contact but when i search for "a" it gives all the section array which has "a" in the contact name. but here i have stuck. It is not necessary that the all contact of the section contain "a" in the contact name.

For example

(
    A:(
        {
            name = "abc"
            number = "123456"
        }
        {
            name = "azx"
            number = "123456"
        }
      )
)

For example for above example after search for "a". when i search for "ab" then same array return by predicate.Not only first object. Any way to find only first object with out nested predicate.

I'm not sure what you are trying to accomplish with the word "ANY" in your predicate but it seems redundant. This code works as you describe when put into a Playground:

import UIKit

@objc class DataElement : NSObject {
    let name : String
    let number : String

    init(name : String, number : String) {
        self.name = name
        self.number = number
    }
}

let dataArray : NSArray = [
    DataElement(name: "abc", number: "123456"),
    DataElement(name: "azx", number: "689101")
]

let searchTerm = "a"
let predicate = NSPredicate(format: "SELF.name CONTAINS[cd] '\(searchTerm)'", argumentArray: nil)

dataArray.filteredArrayUsingPredicate(predicate)
