Array.sort() doesn't sort numbers correctly [duplicate]
...
I've tried different numbers, and it always acts as if the 0s aren't there and sorts the numbers correctly otherwise. Anyone know why?
You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Ja...
Autolayout - intrinsic size of UIButton does not include title insets
...ve left image inset, the actual layout uses half that value. So to get a -20 point left inset, you must use a -40 point left inset value in Interface Builder.
So you provide a big enough left content inset to create space for both the desired left inset and the inner padding between the icon and t...

Understanding FFT output
... where the frequency result occurs twice. Once ready to use in the outputs 0 to N/2, and once mirrored in the outputs N/2 to N. In your case it's easiest to simply ignore the outputs N/2 to N. You don't need them, they are just an artifact on how you calculate your FFT.
The frequency to fft-bin equa...
