How to pass delegate to a UITextField inside an IB_DESIGNABLE?

Question

I have created a custom view and added a UITextField to it.My question is: How can I add a delegate so that the you can set it as the default cmd+drag behaviour of XCode?

My current attempt is by doing something like this:

In my .h file:

#import <UIKit/UIKit.h>

IB_DESIGNABLE

@interface CustomTextField : UIView

   @property (assign, nonatomic) IBInspectable id textFieldDelegate;

@end

and my .m file:

#import "CustomTextField.h"

@interface CustomTextField()

@property (strong, nonatomic) IBOutlet UITextField *textField;

@end

@implementation CustomTextField

- (instancetype)initWithFrame:(CGRect)frame{
    if (self = [super initWithFrame:frame]) {
        [self loadNib];
    }
    return self;
}

- (void)loadNib{

    UIView *view = [[[NSBundle bundleForClass:[self class]] loadNibNamed:@"CustomTextField" owner:self options:nil] firstObject];
    [self addSubview:view];
    view.frame = self.bounds;

}

- (void)setTextFieldDelegate:(id)textFieldDelegate{
    self.textField.delegate = textFieldDelegate;
}

@end

But it doest show up in the left panel of XCode, Connections Inspector Tab.

Also here is my current code.

Update 1:

also if using the code below I get a an error:

-  (id)initWithFrame:(CGRect)aRect
{
    self = [super initWithFrame:aRect];

    if (self)
    {
        [self loadNib];
    }

    return self;
}

- (id)initWithCoder:(NSCoder*)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self)
    {
        [self loadNib];
    }

    return self;
}


- (void)loadNib{
//
//    UIView *view = [[[NSBundle bundleForClass:[self class]] loadNibNamed:@"CustomTextField" owner:self options:nil] firstObject];
//    [self addSubview:view];
//    view.frame = self.bounds;

    UIView *view = [[[NSBundle bundleForClass:[self class]] loadNibNamed:@"CustomTextField" owner:self options:nil] firstObject];
    [view setTranslatesAutoresizingMaskIntoConstraints:NO];
    [self addSubview:view];
    [self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[view]|­" options:0 metrics:nil views:NSDictionaryOfVariableBindings(view)]];
    [self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[view]|­" options:0 metrics:nil views:NSDictionaryOfVariableBindings(view)]];

    self.textLabel.text = @"1";

}

Any suggestions on what should I do?

Update 2 I ended up by replacing the initWithFrame, initWithCoder and loadNib functions with:

- (id)awakeAfterUsingCoder:(NSCoder *)aDecoder
{
    if (![self.subviews count])
    {
        NSBundle *mainBundle = [NSBundle mainBundle];
        NSArray *loadedViews = [mainBundle loadNibNamed:@"CustomTextField" owner:nil options:nil];
        CustomTextField *loadedView = [loadedViews firstObject];

        loadedView.frame = self.frame;
        loadedView.autoresizingMask = self.autoresizingMask;
        loadedView.translatesAutoresizingMaskIntoConstraints =
        self.translatesAutoresizingMaskIntoConstraints;

        for (NSLayoutConstraint *constraint in self.constraints)
        {
            id firstItem = constraint.firstItem;
            if (firstItem == self)
            {
                firstItem = loadedView;
            }
            id secondItem = constraint.secondItem;
            if (secondItem == self)
            {
                secondItem = loadedView;
            }
            [loadedView addConstraint:
             [NSLayoutConstraint constraintWithItem:firstItem
                                          attribute:constraint.firstAttribute
                                          relatedBy:constraint.relation
                                             toItem:secondItem
                                          attribute:constraint.secondAttribute
                                         multiplier:constraint.multiplier
                                           constant:constraint.constant]];
        }

        return loadedView;
    }
    return self;
}
