Merging NSArrays to create new array with objects - objective-c

Question

I have 3 NSArrays, each one with 6 objects:
NSArray *A [Joe, John, Jay, Jason, Jonah, Jeremiah];
NSArray *B [Doe, Smith, Scott, Jackson, Johnson, Lewis];
NSArray *C [1,2,3,4,5,6];
My model is:
#interface Person : NSObject
#property NSString *firstName;
#property NSString *lastName;
#property NSString *number;
#end
I need to create a forth array where each person object has a firstName, lastName, number.
NSArray *D = [0]Joe, Doe, 1
[1]John, Smith, 2
[2]Jay.Scott,3
[3]Jason, Jackson, 4
[4]Jonah, Johnson, 5
[5]Jeremiah. Lewis, 6
How can I do this?

Answer 1

You can do something like following: (On a side note, please declare your class property with proper attributes)
NSArray *A = #[#"Joe", #"John", #"Jay", #"Jason", #"Jonah", #"Jeremiah"];
NSArray *B = #[#"Doe", #"Smith", #"Scott", #"Jackson", #"Johnson", #"Lewis"];
NSArray *C = #[#1, #2, #3, #4, #5, #6];
NSMutableArray *D = [[NSMutableArray alloc] initWithCapacity:A.count];
for (int i=0; i < A.count; i++)
{
Person *p = [[Person alloc] init];
p.firstName = [A objectAtIndex:i];
p.lastName = [B objectAtIndex:i];
p.number = [C objectAtIndex:i];
[D addObject:d];
}
Let me know, how it goes.

Try using enumerateObjectsUsingBlock for array :-
NSArray *A = #[#"Joe", #"John", #"Jay", #"Jason", #"Jonah", #"Jeremiah"];
NSArray *B = #[#"Doe", #"Smith", #"Scott", #"Jackson", #"Johnson", #"Lewis"];
NSArray *C = #[#1, #2, #3, #4, #5, #6];
NSMutableArray *mutArr=[NSMutableArray array];
[A enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
Person *p=[[Person alloc]init];
p.firstName=A[idx];
p.lastName=B[idx];
p.number=C[idx];
[mutArr addObject:p];
}];
NSLog(#"person=%#",mutArr);
