ios - How to determine if NSLayoutConstraint is horizontal or vertical? -


It seems that this should be a simple task, but if a NSLayoutConstraint is a horizontal or vertical The obstacle?

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.

Any suggestion would be very helpful!

Edit:

I accepted the reply of Grimozoar because its interpretation is a great answer and the way I am working to parse the details, @ kongtomorrow I also want to give credit, answered me here! 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; amp; amp; amp; amp; amp; Restriction [second part] == ​​NSLayoutAttributeTop) [[Remove the bubble] Restraint: Obstacle];}} The first one above, corresponds to the second itam, and then the second obligation Contributions are to be convinced with the sure certainty that I am seeing the right obstruction, then I remove it and successfully my new obligation - after the description!   
 
 
 Not really  VFL  embedded code  However, if you check the first attribute on the obligation or the second attribute  NSLayoutAttribute  properties, you can do this horizontal or If vertical can be removed, if you are creating your own obstacles with  VFL , then they are probably not complicated, so this can be a simple deduction. For example, if you get a feature for the first time on a set of supervision, then  NSLayoutAttributeLeft  and the other attribute is  NSLayoutAttributeLeft  for a child's view, then it  The possibility  is horizontal but only probability. 
 
 To simply add horizontal / vertical properties, or to maintain the supportive data for each hurdle, possibly parsing the details in the dictionary, possibly subclassing  NSLayoutConstraint  Want record h or v

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . 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...
