iOS - Storing multiple values in one variable - ios

Question

I am creating 5 integer variables to store 5 different values in Objective C. For ex: intA, intB etc
Below is just sample code:
For example:
for (Desframe *obj in [myval allValues])
{
if (obj.A>10.0) {
myLabel.text = #"A";
intA = intA++;
}
else if (obj.B>10.0) {
myLabel1.text = #"B";
intB = intB++;
}
else if (obj.C>10.0) {
myLabe2.text = #"C";
intC = intC++;
}
else if (obj.D>10.0) {
myLabe3.text = #"D";
intD = intD++;
}
else if (obj.E>10.0) {
myLabe4.text = #"E";
intE = intE++;
}
}
In future, I may need to add 2 more variables.
I would like to know how to avoid creating 5 different integer variables but have 5 different values stored in one variable. Should I use array?
(or) how to handle this code professionally?
But I want this variable to be accessed globally in the same class (.m) file.
Kindly share your suggestion and guidance.

Answer 1

Yes, you can use an NSMutableArray for this. However, Objective-C NSArrays are a little strange since they can only contain objects. You'll have to "box" the entries as NSNumber objects:
NSMutableArray *numbers = #[#(1), #(2), #(3), #(4), #(5)];
And then you can fetch an item from the array:
NSNumber *aNumber = numbers[0];
But NSNumber Objects are immutable.
You might want to use a C-style array:
UInt64 numbers[] = [1, 2, 3, 4, 5];
Then you could say
numbers[0]++;
But with a statically allocated C-style array you can't add elements to the array at runtime.

Answer 2

You could use NSMutableDictionary with keys being your A - E here and integers as values.
That way, for instance, to add values (5 now and potentially more in the future) you would write:
[dict setObject:#123 forKey:#"A"];
To retrieve them:
[dict objectForKey:#"A"];

Answer 3

You could define your own struct.
struct MyStruct {
int a;
int b;
int c;
int d;
}
And use this new type in your class
#implementation MyClass {
MyStruct example;
// In your function
for (Desframe *obj in [myval allValues])
{
if (obj.A>10.0) {
myLabel.text = #"A";
example.a += 1;
}
else if (obj.B>10.0) {
myLabel1.text = #"B";
example.b += 1;
}
// And so on ...
}
}
}
