如何快速获取NSMutableArray中另一个元素的一个元素的所有值

Question

I want to get all the doctor name where Department name is "Internal Medicine.\\n " from NSMutableArray in Swift language .

    (
 {
     DepartmentName = "Internal Medicine.\n ";
     DoctorName = "Dr. A. K. Kundu\n ";
 },
 {
     DepartmentName = "Internal Medicine.\n ";
     DoctorName = "Dr. Arvind K. Minz\n ";
 },
 {
     DepartmentName = "Internal Medicine.\n ";
     DoctorName = "Dr. Rajeev Choudhary\n ";
 },
 {
     DepartmentName = "Obstetrics And Gynaecology.\n ";
     DoctorName = "Dr. Gouri Jain\n ";
 },
 {
     DepartmentName = "Obstetrics And Gynaecology.\n ";
     DoctorName = "Dr. Poonam Kataria\n ";
 },
 {
     DepartmentName = "Obstetrics And Gynaecology.\n ";
     DoctorName = "Dr. Ila Jha\n ";
 },
 {
     DepartmentName = "Internal Medicine.\n ";
     DoctorName = "Dr. Ram Niwas Gupta\n ";
 },
 {
     DepartmentName = "Gasteroenterology.\n ";
     DoctorName = "Dr. Sanjay Kumar\n ";
 },
 {
     DepartmentName = "Neurology.\n ";
     DoctorName = "Dr. Sameer Gupta\n ";
 },
 {
     DepartmentName = "Physiotherapy And Rehabilitation.\n ";
     DoctorName = "Dr. Kapil Chauhan\n ";
 },
 {
     DepartmentName = "X­Ray.\n ";
     DoctorName = "Dr. Gagan Sharma\n ";
 }
)

I can easily get all the department and doctor name by using valueforkey (eg. posts.valueForKey("DoctorName") or posts.valueForKey ("Departmentname") ) and now I want to get all the doctor name where the department name is selected from department list

Answer 1

I suggest you create a new Object named Doctor

class Doctor: NSObject {

    var doctorName = ""
    var departmentName = ""
}

So that you can easily parse your data to new Doctor and store it like an array. It will be easier to filter, find or do anything.

Hope this help.

Answer 2

I solved the problem by easy step :

Here department name and doctor name are on same index SO what i did is simply get indexOfObject() from DepartmentArrray and After that objectAtIndex() from DoctorArray.

Here is my code inside @IBAction func SelectDoctorButton(sender: AnyObject) :

var indexOfObject = 0
            for var index = 0 ; index < self.DepartmentArray.count ; index++ {
                if self.PickValue == self.DepartmentArray[index] as NSString{
                    indexOfObject = index

                    println(" pickValue is at index : \(indexOfObject) ")
                    println(self.DoctorArray.objectAtIndex(index))


                    self.DoctorArrayAsDepartment.addObject(self.DoctorArray.objectAtIndex(index))
