ios - An Xcode macro for creating property setters -

-

I have a class with many properties when each property is set, I need to update the UI of my application is needed. Sets look something like this: 

  @ synthesis tracklightlight color = _trackHighlightColour; - (zero) setTrackHighlightColour: (UIColor *) trackHighlightColour {_trackHighlightColour = trackHighlightColour; [Self update UI]; }   
 Instead of typing it 10 times, I would like to use the macro. This is what I have done so far:  
  #if! Defined (PROPERTY_SETTER) #define PROPERTY_SETTER (PROPERTY_NAME, UPPER_PROPERTY_NAME) @ synthesis (PROPERTY_NAME) = _ (PROPERTY_NAME); \ \ - (zero) set (UPPER_PROPERTY_NAME): (UIColor *) (PROPERTY_NAME) \ {\ _ (PROPERTY_NAME) = (PROPERTY_NAME); \ [Self update UI]; \} #endif   
 Unfortunately, this is something problems.  
     
  1.  Required to repeat (miner) property with repeat name  
  2.  
     The compiler does not allow me to name the property, instead I have to pass it one As a string:  
     @implementation FooClass  
     PROPERTY_SETTER (@ "trackHighlightColour", "TrackHighlightColour");  
     @end    
     It feels very close to leaving this technique.   
     
     
     This is what I am using with MRC  
      #define GENERATE_RETAIN_SETTER (ATTRIBUTE_NAME, UPDATER) \ if (_ ## ATTRIBUTE_NAME! = ATTRIBUTE_NAME) {\ # [## ATTRIBUTE_NAME release]; \ _ ## ATRIBUTEN = [ATIIUUUTUAI]; \ \ [Auto update]; \}   
      
      - (zero) set color: (UIColor *) color {GENERATE_PROPERTY_SETTER (color, updateUI)}    - (zero) set collar: (UIColor *) color {if (_color! = Color) {[_color release]; _color = [color intact]; [Self update UI]; }}   
     This can be changed for your specific needs but there is no way to capitalize the string in the preprocessor. With the latest compiler, you can lose the  @ synthesis , but to actually do what you want, you can create a macro with four parameters  
     < Code> #define GENERATE_RETAIN_SETTER (PROPERTY, TYPE, SETTER, UPDATER) \ @ synthesize PROPERTY = _ ## PROPERTY; \ \ - (zero) SETTER: (TYPE *) property {\ if (_ ## property! = Property) {\ [_ ## property release]; \ _ ## property = [retaining property]; \ \ [Auto update];   
     Using  
      GENERATE_RETAIN_SETTER (Color, UIColor, setColor, updateUI)   
     You should meet    @ synthesis color = _color; - (zero) set collar: (UIColor *) color {if (_color! = Color) {[_color release]; _color = [color intact]; [Self update UI]; }}

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

ios - Replace text in UITextView run slowly -

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
