How to pass delegate to a UITextField inside an IB_DESIGNABLE? - ios

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;
}
