Loading a xib from a view subclass in Swift - ios

Question

I’m trying to reuse a component from a xib in a Swift project, but I’m using Objective C logic. Thus, subclassing a view and loading the xib, then instantiating the custom view in the view controller.
Translating the code into Swift is not producing the results expected.
CustomView.swift:
override init(frame: CGRect) {
super.init(frame: frame)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
fatalError("Error detected")
self.commonInit()
}
private func commonInit() {
NSBundle.mainBundle().loadNibNamed("mainBar", owner: self, options: nil)
self.addSubview(self)
}
viewController.swift:
var bottomBar : customView = customView(frame: CGRect(x: 0, y: 250, width: 250, height: 70))
//bottomBar.backgroundColor = UIColor.redColor()
self.view.addSubview(bottomBar)
Objective-C I used as a reference:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self baseInit];
}
return self;
}
- (id)initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];
if (self) {
[[NSBundle mainBundle] loadNibNamed:#"yourXib" owner:self options:nil];
[self addSubview:self.view];
}
return self;
}
CustomView * myView = [CustomView alloc]init];
[self.view addSubView:myView];
Any comment in the right direction is appreciated.

Answer 1

Not 100 percent sure if your OBJ-C code actually work, but most probably don't.
You have to realise that this [[NSBundle mainBundle] loadNibNamed:#"yourXib" owner:self options:nil]; returns always array of objects in your IB xib files. You actually don't assign this object anywhere as far as I see.
The problem with this implementation might be frame that can be taken from bounds.
This code works if we assume that there is only one object in an IB object.
private func commonInit()
{
var nibView = NSBundle.mainBundle().loadNibNamed("mainBar", owner: self, options: nil)[0] as UIView
nibView.frame = self.bounds;
self.addSubview(nibView)
}

You can try This
override init(frame: CGRect) {
super.init(frame: frame)
loadViewFromNib ()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
loadViewFromNib ()
}
func loadViewFromNib() {
let view = UINib(nibName: "CreditCardExperyView", bundle: NSBundle(forClass: self.dynamicType)).instantiateWithOwner(self, options: nil)[0] as! UIView
view.frame = bounds
view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
self.addSubview(view);
}
// Call subview
let creditCardView : CreditCardExperyView = CreditCardExperyView(frame: CGRect(x: 0, y: UIScreen.mainScreen().bounds.size.height - 280, width: UIScreen.mainScreen().bounds.size.width, height: 280))
selfView.addSubview(creditCardView)
