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);

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
