just getting back into coding after a long break, and picking up Objective C.
I want to add multiple objects to an array. I can do it explicitly (as below) but I'm sure there must a smarter, iterative way to do it.
NSMutableArray *a =[NSMutableArray array];
Class A *c1 = [[Class A alloc]init];
[c1 setVAlueX:5];
[c1 setValueY:3];
[a addobject:c1];
Class A *c2 = [[Class A alloc]init];
[c2 setVAlueX:5];
[c2 setValueY:3];
[a addobject:c2];
Class A *c3 = [[Class A alloc]init];
[c3 setVAlueX:5];
[c3 setValueY:3];
[a addobject:c3];
etc

Answer 1

This is nice and short:
NSArray *a = #[[A aWithX:5 Y:3], [A aWithX:5 Y:3], [A aWithX:5 Y:3]];
You'll have to implement a convenience constructor in class A:
+ (instancetype)aWithX:(int)x Y:(int)y
{
A *a = [[self alloc] init];
[a setValueX:x];
[a setValueY:y];
}

Answer 2

Try this
NSMutableArray *a =[[NSMutableArray alloc] init];
NSMutableArray *b =[[NSMutableArray alloc] init];
NSMutableArray *c =[[NSMutableArray alloc] init];
NSMutableDictionary *dictA = [[NSMutableDictionary alloc] init];
NSMutableDictionary *dictB = [[NSMutableDictionary alloc] init];
NSMutableDictionary *dictC = [[NSMutableDictionary alloc] init];
Class A *c1 = [[Class A alloc]init];
[dictA setObject:[NSString stringWithFormat:#"5"] forKey:#"ID1"];
[dictA setObject:[NSString stringWithFormat:#"3"] forKey:#"ID1"];
//[c1 setVAlueX:5];
//[c1 setValueY:3];
[a addobject: dictA];
Class A *c2 = [[Class A alloc]init];
[dictB setObject:[NSString stringWithFormat:#"5"] forKey:#"ID1"];
[dictB setObject:[NSString stringWithFormat:#"3"] forKey:#"ID1"];
//[c2 setVAlueX:5];
//[c2 setValueY:3];
[a addobject: dictB];
Class A *c3 = [[Class A alloc]init];
[dictC setObject:[NSString stringWithFormat:#"5"] forKey:#"ID1"];
[dictC setObject:[NSString stringWithFormat:#"3"] forKey:#"ID1"];
//[c3 setVAlueX:5];
//[c3 setValueY:3];
[a addobject: dictC];
