I am trying to use the array of strings that is named "theList" in another class in my project. I understand that the variable is declared within a method and therefore not of global scope. But how can I fix that? I have tried a few things and nothing is working. What is the best way to accomplish this?
EDIT: All I want to do is set "theList" equal to "Body" [![enter image description here][1]][1]
I hope this clears it up a little bit, and I can select an answer. Thanks to everyone!
I think if you want to access that list outside of the function you should simply make it a variable of the class.
class TaskManager: NSObject {
//Sets up array of Tasks
var tasks = [task]()
var theList = [String]()
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
theList = tasks.map({ (task) -> String in
return task.serial
})
}
}
Your best way to do this is to look at the scope of your class and the declaration. Define your list in a place that has scope everywhere you want to use it, or make it global. That's how I do this kind of task. Sometimes add it to a higher level class declaration, and sometimes I make it global to, say, the entire program. Depends on the task and my outlook at the time of coding.
Let you function return the results of adding the task then:
class TaskManager: NSObject {
// declare your variables
func addTask(serial: String) -> [String] {
// put your realisation
}
}
or make your variable with serials available publicly:
class TaskManager: NSObject {
var tasks = [Task]()
public var serials = [String]()
func addTask(serial: String) {
// put your realisation
// save the results to serials
}
}
and then access it via the instance.
public class TaskManagerAdding theList Variable above class made it global. Then I had to remove let from the addTask function.
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
let theList = tasks.map({ (task) -> String in
return task.serial
}).joinWithSeparator("\n")
Became
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
theList = tasks.map({ (task) -> String in
return task.serial
}).joinWithSeparator("\n")
The final code is as follows.
import UIKit
var theList : String = String()
var taskMgr: TaskManager = TaskManager()
struct task {
var serial = "Un-Named"
}
public class TaskManager: NSObject {
//Sets up array of Tasks
var tasks = [task]()
//Add Task Function
func addTask(serial: String){
tasks.append(task(serial: serial))
theList = tasks.map({ (task) -> String in
return task.serial
}).joinWithSeparator("\n")
do {
//try tasksString.writeToFile(pathToFile, atomically: true, encoding: NSUTF8StringEncoding)
print(theList)
}
}
}
I selected the answer. Thank you to all who helped cure my tired eyes.
