Question

StockHolding is my own class name, and I want to create 3 instance variables. The working-copy of code is like this:

StockHolding *stock0 = [[StockHolding alloc] init];
StockHolding *stock1 = [[StockHolding alloc] init];
StockHolding *stock2 = [[StockHolding alloc] init];

But the first time of my code is like this:

StockHolding *stock0, *stock1, *stock2 = [[StockHolding alloc] init];

which will not work for me 🙁

I know that I can create multiple float/int variables in the way :

float *x, *y, *z;

So my question is, is there any way to make it possible to alloc multiple instance varialbes in such way in Objective-C ?

Answer 1

StockHolding *stock0, *stock1, *stock2 = [[StockHolding alloc] init];

is the same as

StockHolding *stock0;
StockHolding *stock1;
StockHolding *stock2 = [[StockHolding alloc] init];

It doesn’t really make sense to initialize multiple objects on one line. Your first approach is fine.
