Question

i see the function CGPathEqualToPath which i successfully used to compare data from 2 UIbezierPaths (technically, i compared a path to itself).

Is there any way to modify this function to find out how similar 2 paths are? and perhaps make a threshold to say, ok, these paths are close enough to be considered the same?

(i’m using iOS)

also, unrelated. i have a mutable array of bezierpaths. what is the notation for accessing a particular element of the array? i’m new to this. thanks

I don’t think you can create a likeness function as you don’t have access to the underlying structure or functions that provide access to those values. If you can elaborate the use case, maybe there is an alternate solution.

As for accessing an object at a particular index in an array, you can do it using –

id myObject = [array objectAtIndex:particularIndex];
