Question

I’ve been looking for this, but can’t find the answer.

I have an NSMutableArray with values who_1, what_2, where_3 etc.

I want to transform this into who, what, where etc.

I already have the value of the integer as a variable, and _ is just a string.

What steps should I take to have all these arrayvalues transformed?

Answer 1

 NSArray * arrB = [[NSArray alloc]initWithObjects:@"apple_a",@"ball_b",@"cat_c",@"doll_d",nil]; 

 NSMutableArray * arrA = [[NSMutableArray alloc]init];


for(NSString *strData in arrB)
    {
        NSArray *arr = [strData componentsSeparatedByString:@"_"];
        [arrA  addObject:[arr objectAtIndex:0]];
    } 

and this would be your output

arrA:(
    apple,
    ball,
    cat,
    doll
)
