Convert NSData to float array in Objective-C

What is the most efficient way to convert a NSData to a float array?

I've the following:

NSData* dataOutputNumDetections = [outputNumDetections dataWithError:&error];
NSLog(@"%@",dataOutputScore);

Resulting this:

 {length = 100, bytes = 0xf1699f3e cef5953e 32278d3e ae668b3e ... 6606483e 64ff463e }

NSData dataOutputNumDetections contains 25 float32 values. I would like to convert all the bytes values and store the result in a size 25 float array.

Is it possible?

This works

float output[25];
[dataOutputScore getBytes:output length:(sizeof(float) * 25)];
