Array of doubles objective c

Question

Is there something like NSMutableArray that will take doubles directly without putting them inside the @""?

Solution 1

You can only put objects into an NSMutableArray. But you can wrap your doubles in NSNumber like so:

NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:0];
[array addObject:[NSNumber numberWithDouble:0.12345]];
[array addObject:[NSNumber numberWithDouble:5.43210]];

Solution 2

You can only insert objects into an NSMutableArray. Luckily, there is a class, NSNumber, that is used to wrap Objective-C primitives as objects. You can use the doubleValue method to get your primitive value back.

For example:

NSMutableArray *numArray = [[NSMutableArray alloc]initWithObjects:[NSNumber numberWithDouble:1.1f], nil];
double num = [[numArray objectAtIndex:0]doubleValue];
