ios - UITabBarController display -

-

i newbie in ios development. developing application using tab bar controller. setting frame tab bar controller programmatically when switch iphone 5 there white space created between tab bar items , main view. following screen shot of application on iphone 5 simulator.

screen shot on 4.5 retina display simulator

following line of code setting frame uitabbarcontroller:

[roottabbarcontroller.view setframe:cgrectmake(0,-20,320, 480)];

put line of code , check it,you have set frames accordingly.

 

if ([[uiscreen mainscreen] bounds].size.height == 568)      {         [roottabbarcontroller.view setframe:cgrectmake(0,0,320, 568)];      }  else      {         [roottabbarcontroller.view setframe:cgrectmake(0,0,320, 480)];      }

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

ios - UISlider customization: how to properly add shadow to custom knob image -

Image
i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
