adding a viewControllers view to another viewController

I am completely new to iPhone development. I have two ViewControllers

1. ViewControl开发者_JAVA百科lerA
2. ViewControllerB

ViewControllerA is the first one and launches with the app.

I have another ViewControllerB now I want to add view of ViewControllerB as subview to ViewControllerA's view when application launches.

Try this

ViewControllerB *vcb = [[ViewControllerB alloc] init];

[self.view addSubview:vcb.view];

A belated answer. I just wrote some words about my solution for this question. It can be found here: http://blog.nguyenthanhnhon.info/2014/04/how-to-add-viewcontrollernavigationcont.html

You need to declare the object of VC globally .. otherwise you face some issues.

@interface ViewControllerA ()

{

ViewControllerB *viewControllerBObj;

}

-(void) viewDidLoad

{

[super viewDidLoad];

viewControllerBObj = [[ViewControllerB alloc]initWithNibName:@"ViewControllerB" bundle:nil];


[self.view addSubview:viewControllerBObj.view];

}

try this

in "viewDidLoad" method of "ViewController1"

ViewController2 *vc2 = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController2"];
[self addChildViewController: vc2];
[self.view addSubview: vc2.view];

You can access the view of a view controller by using it's view property. If you have pointers to two view controllers myControllerA and myControllerB then you can add B's view to A's view by using this.

[myControllerA.view addSubview:myControllerB.view];

Add [self.view addSubView:ViewControllerB.view] in the viewDidLoad() of ViewControllerA.
