xcode - How to decide dynamically which screen to transition to (iOS Game) -

-

i'm little bit confused how best perform screen transitions in game. need perform following transitions [main menu] -> [character select] -> [stage select]

up until using interface builder "click 'n drag" control in [main menu] [character select] , choosing modal segue type. realized that, on second run of game, player doesn't need go [character select] screen again. i'd have following flow [main menu] -> [stage select]

so question(s) are:

1) modal transition recommended way of doing this? examples saw using modal transitions popup or similar. don't want use navigation bars because think not design options game.

2) saw somewhere should not use segues here, instead i'd use "presentviewcontroller:animated:completion:" led me set of questions.

3) in order understand presentviewcontroller... ended in apple doc http://developer.apple.com/library/ios/#featuredarticles/viewcontrollerpgforiphoneos/modalviewcontrollers/modalviewcontrollers.html not explain many things,

3.1) instance how set nib file name of controller in inteface builder? (do have create .xib file). nib/xib file confusing.

i tried pass in name of controller class nib name this:

mycontroller* controller = [uiviewcontroller alloc] initwithnibname:@"mycontroller"...

but exception "could not load nib in bundle..."

3.2) document states should set controller.delegate self uicontroller not have delegate property. have define delegate property in presented controller myself?

3.3) second argument, "bundle", should pass in 'nil' or should pass in mainbundle?

thanks in advance.

you should use segue call to:

- (void)performseguewithidentifier:(nsstring *)identifier sender:(id)sender

when want perform [main menu] -> [stage select] transition. create segue in uiviewcontroller subclass, configure it, , use needed.

alternately, in view have uicontrol [main menu] -> [character select] could:

  1. change segue performs
  2. disable , hide while enabling , unhiding control menu->stage segue

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
