ios - How do I make a button stay pressed? -

-

okay have app i'm building complete. i'm having 1 problem, when press button makes sound , button's image changes. image changes when being touched or "highlighted" , buttons image remain changed through duration of sound effect after sound effect revert original image. there anyway can set uibutton "set time" or "highlighted" option?

i feel embarrassed sometimes, because seem tripped these trivial things, when handle core coding exceptionally , near finish full app in days time, first app , i'm still newbie xcode. appreciate community's answer pushes me forward appreciated!

i further apologize questions formatting typed on iphone hope it's not awkward or lacking in detail. if needs more detail ask!

1.you dont want reflection of image @ highlighted , selected state. put same image state like

[btnclear setbackgroundimage:[uiimage imagenamed:@"blue_button.png"]                             forstate:uicontrolstatenormal]; [btnclear setbackgroundimage:[uiimage imagenamed:@"blue_button.png"]                             forstate:uicontrolstatehighlighted]; [btnclear setbackgroundimage:[uiimage imagenamed:@"blue_button.png"]                             forstate:uicontrolstateselected];

2.now if want image change @ sound stop time make 

[btnclear setbackgroundimage:[uiimage imagenamed:@"red_button.png"]                             forstate:uicontrolstatenormal]; [btnclear setbackgroundimage:[uiimage imagenamed:@"red_button.png"]                             forstate:uicontrolstatehighlighted]; [btnclear setbackgroundimage:[uiimage imagenamed:@"red_button.png"]                             forstate:uicontrolstateselected];

and again on button click toggle image first one.

(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...
