Creating a NSArray from a C Array

问题

There are many threads about going the opposite way, but I am interested in converting from a primitive C array to a NSArray. The reason for this is that I want to create a NSString from the array contents. To create the NSString I will use:

NSArray *array;
NSString *stringFromArray = [array componentsJoinedByString:@","];

I am joining the elements of the array by commas because I will later be saving the string as a .csv file. I don't think it matters, but the C array I am dealing with is of type double and size 43.

double c_array = new double [43];

Thanks!

回答1:

NSString * stringFromArray = NULL;
NSMutableArray * array = [[NSMutableArray alloc] initWithCapacity: 43];
if(array)
{
    NSInteger count = 0;

    while( count++ < 43 )
    {
        [array addObject: [NSString stringWithFormat: @"%f", c_array[count]]];
    }

    stringFromArray = [array componentsJoinedByString:@","];
    [array release];     
}
