iOS byte stream to int

[OldGit]

In java there is a method "readInt()" which returns an int from byte array. What is the equivalent method to convert bytes to int (or float or other datatype)?

Assuming 4-byte ints, something like:

int i = (b[0] << 24) + (b[1] << 16) + (b[2] << 8) + b[3];

Though be aware that sizeof(int) will likely differ depending on whether you're building for simulator or device.
