objective c - iOS compare NSUInteger to NSInteger -


I am trying to compare each other with numerical values ​​but compare me with the "integer comparison of different signals" (Aka 'inti') and 'nsuentengar' (aka 'unsigned' int).

Which is rational, I do this;) But how can I correct this warning? This is the code that warns: 

  if (page> = self.controllers.count || page & lt; 0) returns;

Page -1 can therefore be an NSInteger but is counted on an NSUntiger. Instead of using NSINtegaer for page and -1, use NSUInteger and NSNotFound where you - 1.

Then you are comparing the same type. 

  Return (page & gt; = self.controllers.count || page = = NSNotFound);

I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage").

Passing control scheduler as you have got subsc...

The only way to try to make this difference is by [constraint description]; Calling and then the resulting string "V:" or "H:" I want to find this information, because of I have around 2 similar restrictions which are prototype storyboard UITableViewCell , the only difference is that supervision is horizontal Describes the distance, and the second vertical.

Thanks for the help! Here is the real code that I used to find the hindrance: NSArray * constraints = [bubble constraints]; (If ([[obstacle first item]], then e-mail: message labels] and [[barrier is second int.] Is aqual: bubble] and amp; a...

c# - Updated Castle to 3.2.1 from 3.0.0 now I cant use FirstNonGenericCoreInterface -

Image
After I upgraded to 3.2.1 Castle I think I can not find the right replacement for the FirstNonGenericCoreInterface My code container.Register (AllTypes .FromAssemblyNamed ("MySolution.Tasks") .Innamespace ("MySolution.Tasks") .WithService.FirstNonGenericCoreInterface ("MySolution.Domain" )); This method is not obsolete and which method I can not use it Does anybody know what I should use instead? If I'm not mistaken, FirstNonGenericCoreInterface is an intense architecture extension method. WithService.DefaultInterfaces () does that, then what should you do with your implementation class name interface? More information is available at Castle Windsor Wiki
