Question

I\'m experiencing excessive UIBarButtonItem padding/spacing when using the LeftBarItems and RightBarItems (see image below). The icons used on the UIBarButtonItems do not co

As @Luda comments, the solution is to

self.myBarButtonItem.imageInsets = UIEdgeInsetsMake(0, 25, 0, -25);

However, @andrrs also points a problem here when inset is large: the hit area. In this case,we have to implement a way to setHitTestEdgeInsets. Below is an category method:

@implementation UIButton (Extensions)

@dynamic hitTestEdgeInsets;

static const NSString *KEY_HIT_TEST_EDGE_INSETS = @"HitTestEdgeInsets";

-(void)setHitTestEdgeInsets:(UIEdgeInsets)hitTestEdgeInsets {
    NSValue *value = [NSValue value:&hitTestEdgeInsets withObjCType:@encode(UIEdgeInsets)];
    objc_setAssociatedObject(self, &KEY_HIT_TEST_EDGE_INSETS, value, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

-(UIEdgeInsets)hitTestEdgeInsets {
    NSValue *value = objc_getAssociatedObject(self, &KEY_HIT_TEST_EDGE_INSETS);
    if(value) {
        UIEdgeInsets edgeInsets; [value getValue:&edgeInsets]; return edgeInsets;
    }else {
        return UIEdgeInsetsZero;
    }
}

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {
    if(UIEdgeInsetsEqualToEdgeInsets(self.hitTestEdgeInsets, UIEdgeInsetsZero) ||       !self.enabled || self.hidden) {
        return [super pointInside:point withEvent:event];
    }

    CGRect relativeFrame = self.bounds;
    CGRect hitFrame = UIEdgeInsetsInsetRect(relativeFrame, self.hitTestEdgeInsets);

    return CGRectContainsPoint(hitFrame, point);
}
