ios - Show glow when a button is touched -

-

trying use info button in ios app. wondering if knows how simulate glow effect when click on it.

see example weather or stocks apps in iphone; when touch it, glow highlight around touch. touch , hold see it.

uibutton has property called showstouchwhenhighlighted. default set no.

if set yes glow effect when button highlighted.

you can set in interface builder checking "shows touch on highlight" option.

or can in code with:

infobutton.showstouchwhenhighlighted = yes;

this applies uibuttons, not info ones.

(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...
