objective c - Data definition has no type or storage class with float array definition -

i'll find answer enough blind experimentation or better google search, but.. might benefit others.

this not inside class definition, in .m objective-c file. i've got declaration of float array giving me following 2 warnings in xcode. errors show on declaration line, not assignment line.

data declaration has no type or storage class. type defaults 'int' in declaration

then assignment fails - if variable defaulting int, happen.

here's code. first declaration (static const float array initializer) doesn't give error, nor second (simple float). third , forth (float arrays) do.

static const float offset3d[4] = {     0.0, 0.0, -2.0, 0.0 }; float boxv; float boxv0[3]; float boxv1[3];  boxv0[0] = -0.5; // gives error of trying assign float (default) int 

you need put boxv0[0] = -05.; inside method somewhere. each of declarations should work, , assignment should fail. first assignment works because assign declared array- acceptable because compiler can create memory location , fill it. last 1 fails because attempt modify dynamically outside class method, compiler not allow. finally, if getting warnings on declarations, might have else going on.
