import UIKit


// 1.  Write a function that takes no arguments and returns a view that is the size of the screen and is colored red.  The function should return an AnyObject instead of a UIView, since a UIView cannot pass the C/C++ boundary.


func gimmeUIView() -> AnyObject {
    let newView = UIView(frame: UIScreen.mainScreen().bounds)
    newView.backgroundColor = .redColor()
    return newView
}

//2.  Suppose that I have a function whose C interface is as follows: void GetProductDescription(const char * input, const char * output).  This function takes text input and produces a product description in the output argument.  Please write a function that takes a string input (in the language of your choice) and returns a view (AnyObject) that is a blue UILabel with the extracted product description written on the label in white text.

func gimmeUILabel(stringInput: String) -> AnyObject {
    
    var output: [CChar] = []
    
    var descriptionOutput = ""
    
    GetProductDescription(output, outdoor: output)
    
    if output != [] {
        
    descriptionOutput = String.fromCString(&output)!
    }
    
    
    let newlabel = UILabel(frame: CGRectMake(0,UIScreen.mainScreen().bounds.height/2, UIScreen.mainScreen().bounds.width, 50))
    let titleAttributes = [
        NSFontAttributeName: UIFont.preferredFontForTextStyle(UIFontTextStyleHeadline),
        NSForegroundColorAttributeName: UIColor.whiteColor()
        
    ]
    let titleString = NSMutableAttributedString(string: "\(descriptionOutput)", attributes: titleAttributes)
    newlabel.attributedText = titleString
    newlabel.textAlignment = .Center
    newlabel.backgroundColor = .blueColor()
    return newlabel
}
