Creating gradients with Core Graphics in iOS -

-

i have following code create gradient (or start of one):

cagradientlayer *gradient = [cagradientlayer layer];   uicolor *lightgreen = [uicolor colorwithred:66.0f/255.0f green:79.0f/255.0f blue:91.0f/255.0f alpha:1.0f]; uicolor *darkgreen = [uicolor colorwithred:66.0f/255.0f green:79.0f/255.0f blue:91.0f/255.0f alpha:1.0f];

why line give me "expected identifier"?

gradient.colors = [nsarray arraywithobjects:(id)[lightgreen.cgcolor]];

you have many [ in code , not closing , nil:

gradient.colors = [nsarray arraywithobjects:(id)[lightgreen.cgcolor]];

should be:

gradient.colors = [nsarray arraywithobjects:(id)lightgreen.cgcolor, nil];

or even:

gradient.colors = @[(id)lightgreen.cgcolor];

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
