iPhone device vs. iPhone simulator

Question

I have heard of apps not working properly on the simulator but working properly on the actual iPhone device. Has anyone experienced an app that runs perfectly in the simula

Answer 1

The order in which function/constructor parameters are evaluated is different:

int i = 0;

int f() { return ++i; }

int a, b;

int test(int p1, int p2) {

    a = p1;

    b = p2;

}

test( f(), f() );

//simulator: a = 2, b = 1

//device: a = 1, b = 2
