Custom navigation bar back button hit area - ios

Question

I have implement custom back Navigation bar button.
Codes:
-(UIBarButtonItem*) logicToAddBackButton {
UIImageView *imageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"UiNavigationBack"]];
UILabel *label=[[UILabel alloc] init];
[label setTextColor:[UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0]];
[label setText:#"Home"];
[label sizeToFit];
int space=6;
label.frame=CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+space, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0, label.frame.size.width+imageView.frame.size.width+space, imageView.frame.size.height)];
view.bounds=CGRectMake(view.bounds.origin.x+8, view.bounds.origin.y-1, view.bounds.size.width, view.bounds.size.height);
[view addSubview:imageView];
[view addSubview:label];
UIButton *button=[[UIButton alloc] initWithFrame:view.frame];
[button addTarget:self action:#selector(eventBack) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:button];
[UIView animateWithDuration:0.33 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
label.alpha = 0.0;
CGRect orig=label.frame;
label.frame=CGRectMake(label.frame.origin.x+25, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
label.alpha = 1.0;
label.frame=orig;
} completion:nil];
UIBarButtonItem *backButton =[[UIBarButtonItem alloc] initWithCustomView:view];
return backButton;
}
self.navigationItem.leftBarButtonItem = [self logicToAddBackButton];
This is how it look and work fine according to the logic.
Issue: If we click on first half of arrow, the back button do not respond.
Please suggest on this.

Answer 1

Try to set to your button:
button.contentEdgeInsets = UIEdgeInsetsMake(<#CGFloat top#>, <#CGFloat left#>, <#CGFloat bottom#>, <#CGFloat right#>)

Answer 2

I think you miscalculating frame somewhere.
Why don't you add UIButton instead? It will be much easier, but without label animation.
UIButton *button = [[UIButton alloc] init];
[button addTarget:self action:#selector(eventBack:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Home" forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:#"UiNavigationBack"] forState:UIControlStateNormal];
[button setTitleColor:[UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0] forState:UIControlStateNormal];
[button sizeToFit];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:button];
return backButton;
