ios - How to enable and disable certain UISegmentedControl segments based on selection in preceding segments -


I am trying to enable / disable certain sections, depending on the selection in the first section containing the controls 2 selects different segmented controls user.

First Section: Black | Lal Green |

Second section: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13. 14 | 15 | 16 | 17 | 18 |

Third clause: | 19 | ..... | 36 | 00 |

I want the functionality to be that if the user selects black, then only a few numbers in the second and third sections should be triggered. enabled = yes

Since the second and third sections require the initial input of the first block, I have completely disabled the Segment in VeeDidLoad 

  - (zero) viewDidoadload [[Super Viewedload]; // Setup an additional after loading the view // Do not ensure what to use and why [auto. Second set set enabled: no]; //self.secondSegment.enabled = NO; [Self. Third set set enabled: no]; //self.thirdSegment.enabled = NO; }   
 Good, now it is disabled and gray (desired behavior). But when the user taps on "black", I want some number in the  secondSegment  and  third segment  properties to be able to select the user:    - (IBAction) Color changed: (ID) Sender {UISegmentedControl * secondRow = self.secondSegment; UISegmentedControl * thirdRow = self.thirdSegment; NSString * colorName; NSInteger colorIndex = [Segment indices selected to select oneself]; If (colorIndex == 0) {colorName = @ "black"; } Else if (colorIndex == 1) {colorName = @ "Red"; } Else if (colorIndex == 2) {colorName = @ "green"; } // NSLog is correct and when you choose NSLog (@ "% @", colorName) displays the correct color; // red numbers 1,3,5,7,9,12,14,16,189, 21, 23, 25, 27, 30,32,34,36 / s 0 and 00 / if they are selected " Black "I want to re-enable these areas for the other sections if (color indicator == 0) {[secured set enable: yes SEZTindex: 2]; [Set the second line enabled: Yes, SEZ and EX: 4]; [Set the second line enabled: Yes, SEZ & X: 6]; [Set the second row enabled: yesgateindex: 8]; [Set second row enabled: Yes for SEZEndex: 10]; [Set the second line enabled: yesgateindex: 11]; [Set the second line enabled: Yes, SEZAdWordsX: 13]; [Set second row enabled: Yes, SEZ and XX: 15]; [Set the second line enabled: yesGuitindex: 17]; }}   
 Finally, I do not have both fields enabled (as is ready in ViewDidLoad) and for some reason they will not be able to enable when I explicitly enable each segment I will tell separately. I can enable the full second sezing by doing only  self.secondSegment.enabled = YES , but I can not understand why I can not enable specific areas for my life.  
  
 
 
 You must first enable the controls containing the segment. You can then enable or disable individual segments.  
 Perhaps you should have the split control enabled at all times, and only different segments should be updated based on the color. [Second row set enabled:  
 (Color index == 2) segmentoutindex: 0]; [Set the second row enabled: (color index == 1) for segmentoutindex: 1]; [Set the second line enabled: (color index == 0) for segmentoutindex: 2]; [Set second row enabled: (color index == 1) for segmentoutindex: 3]; // ...   
 Of course it can be simplified with a loop.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
