UI CheckBox Button Not Changing Image - ios

Question

I am trying to set up a class for a UI Button I created for a custom checkbox. For some reason my image is not being set by Xcode. Yet I have other classes in my application that are setting images without a problem.
Checkbox.h
#import <UIKit/UIKit.h>
#interface checkBoxButton : UIButton
#property (nonatomic,assign) IBInspectable BOOL checked;
#end
Checkbox.m
#import "checkBoxButton.h"
#implementation checkBoxButton
-(id) init {
self = [super init];
if(self) {
[self addTarget:self action:#selector(changeState) forControlEvents:UIControlEventTouchUpInside];
}
return self;
}
- (void)checkedBox:(BOOL) checked{
self.checked = checked;
if(!self.checked){
[self setImage: [UIImage imageNamed:#"checked.png"] forState:UIControlStateSelected];
} else {
[self setImage: [UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
}
}
- (void) changeState {
self.checked = !self.checked;
[self sendActionsForControlEvents:UIControlEventValueChanged];
}
#end

Answer 1

-(id) init {
self = [super init];
if(self) {
self.checked = !self.checked;
[self addTarget:self action:#selector(checkedBox:) forControlEvents:UIControlEventTouchUpInside];
}
return self;
}
- (void)checkedBox:(BOOL) checked{
if(!self.checked){
self.checked = checked;
[self setImage: [UIImage imageNamed:#"checked.png"] forState:UIControlStateNormal];
} else {
self.checked = !checked;
[self setImage: [UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
}
}
Try it.
