Question

I have 3 viewcontroller. FirsViewController, SecondViewController and ThirdViewController. The FirstviewController is root viewcontroller and it is adding secondviewcontrooler xib as the subview. like..

[firstviewcontrollerObject.view addsubview:secondViewcontrollerObj.view].

In secondViewcontroller I have one button. When button touch action is called, ThirdViewController is loaded. like..

[SecondViewControllerobj.view addsubview:thirdviewcontrollerobj.view];

Now ThirdViewCOntroller is on the screen. This viewcontroller has nothing only a small button. So I am seeing 2 buttons on screen. First button is of SecondviewCOntroller and second button is of ThirdViewCOntroller. But, I am able to give touch action of 3rdviewcontroller only not 2ndviewcontroller button.

How should I design my view to take touch of both button and I don’t want to merge both controller i one.

I think you should implement it without using multiple UIViewControllers.

View Controllers are useful for pushing and poping from a navigation stack: with only one view displayed at time. I did not try, but I think that’s why you get the bug.

But you prefered navigationControllers to the benefits of their xib, did’t you?

If so, there is a way to use xib with views :

NSArray * arr1 = [[NSBundle mainBundle] loadNibNamed:@"MyView1" owner:nil options:nil];
NSArray * arr2 = [[NSBundle mainBundle] loadNibNamed:@"MyView2" owner:nil options:nil];
NSArray * arr3 = [[NSBundle mainBundle] loadNibNamed:@"MyView3" owner:nil options:nil];
UIView * v1 = [arr1 objectAtIndex:0];
UIView * v2 = [arr2 objectAtIndex:0];
UIView * v3 = [arr3 objectAtIndex:0];

// now you have your 3 views, do what you want with them:
v1.center = CGPointMake(100,100);
[self.view addSubview:v1];
v2.center = CGPointMake(100,200);
[self.view addSubview:v2];
v3.center = CGPointMake(100,300);
[self.view addSubview:v3];
