Hi can I ask if can I mix the xib with my UIViewController in storyboard? Like they share a controller in their files owner because I'm planning to create a expandable view by using nib as the expandedview and I want to pass a value from nib file to the UIViewController in storyboard. Thanks.
I don't recommend you mix xib and view controller from storyboard and hook them all together.
If you want to add a UIView as an extended view to your view controller you can do something like this:
// Load the first view inside our xib from main bundle
UIView *view = [[NSBundle mainBundle] loadNibNamed:#"nib_name" owner:self options:nil][0];
// Define new X,Y to our view
float new_x_position = 0;
float new_y_position = 400;
view.frame = CGRectMake(new_x_position, new_y_position, CGRectGetWidth(view.frame), CGRectGetHeight(view.frame));
// UILabel inside our nib, '111' is the tag we set to our UILabel
UILabel *label = (UILabel*)[view viewWithTag:111];
// Add our view to the current view as a sub view
[self.view addSubview:view];
I hope I understood you correctly.
In storyboard you are not provided with xibs, but if you want to use them to load from nib then use :
MyViewController *viewController = [[MyViewController alloc] initWithNibName:#"CustomDownloadedXib" bundle:nil];

I'm having a little trouble with essentially flipping a UIView to imitate a card turning over.
As it stands, I have created two UIViews (front and rear) inside a XIB and loaded it into the storyboard as such:
//Initiate the view from the XIB
CustomClass *drag = [[CustomClass alloc] initWithFrame:rect];
//Add the view to the view (container) within the storyboard
[self.draggableView addSubview:drag];
Inside my custom class is the following:
-(id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
self = [[[NSBundle mainBundle] loadNibNamed:#"Draggable"
owner:self
options:nil] objectAtIndex:0];
return self;
}
This satisfactorily presents the front view...
Now I cannot for the life of me work out how to flip the view to display another UIView inside the same XIB... This UIView is available at "objectAtIndex:1".
I'm pretty certain the code I need includes:
[UIView transitionWithView:UIVIEW
duration:0.5
options:UIViewAnimationOptionTransitionFlipFromBottom
animations: ^{}];
If xib has many views, You should use loadNibNamed to create the view in xib file:
NSArray *views = [[NSBundle mainBundle] loadNibNamed:#"BlueView" owner:nil options:nil];
self.blueView = views[0];
self.yellowView = views[1];
I have my normal view controller, but once in awhile I'll present something of an options screen atop the view controller. I don't know how to set this up in a Storyboard though, as if I had it on top and then set hidden to true, it would obstruct all the other views and be rather annoying to fiddle around with.
What should I be doing in this case?
You can create the view in a separate XIB file, and then load the view from your view controller programmatically. If this view is showed often you can keep the view in a property, otherwise you can just load it from the XIB every time. To load a view contained in a XIB:
UIView *view = [[[NSBundle mainBundle] loadNibNamed:#"View" owner:self options:nil] firstObject];
[self.view addSubview:rootView];
If this view is something like a settings, I'd recommend to use a separate view controller. You could use a Storyboard and then programmatically add it as a child view controller.
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"MyStoryboard" bundle:nil];
UIViewController *vc = [sb instantiateInitialViewController];
[self addChildViewController:vc];
content.view.frame = self.view; // here you set the frame of your view
content.view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;
[self.view addSubview:vc.view];
[vc didMoveToParentViewController:self];
Are you trying to create a view that is smaller than the view controller?
If that's the case then you can create one programmatically by sub classing UIView.
But if it will cover your entire view controller then you can create a view controller with a .xib file. You can then draw everything on it using IB and then call that view controller morally.
I have developed a custom UIView with nib file such that I can reuse it whenever needed. Now the thing is I have a nib of a UIViewController and I am drag and drop a Dummy UIView inside it and changing the Class Name to custom view's class name. This works fine when I run my application. I can see the Custom View in my screen on runtime. But I can not see it in Interface builder. So, my question is, is it possible to see the custom view's layout in view controller's nib through interface builder?
You can't load a nib from inside another nib.
You could get around this by leaving the view in your view controller's nib as a placeholder, then loading the custom view's nib in viewDidLoad:
- (void)viewDidLoad {
[super viewDidLoad];
UINib *customViewNib = [UINib nibWithNibName:#"CustomView" bundle:nil];
CustomView *customView = [[customViewNib instantiateWithOwner:self options:nil] objectAtIndex:0]
customView.frame = self.placeholderView.bounds;
[self.placeholderView addSubView:customView];
}
I'm developing an iOS app with latest SDK.
I want to create a custom UIView and set layout using a XIB file.
To this XIB, I have added four UIButtons using Interface Builder.
Now I want to connect these four buttons to my custom UIView class and manage there IBActions. This is very important, I have to do it this way.
To load the xib I do:
- (id)initWithCoder:(NSCoder *)aDecoder {
if ((self = [super initWithCoder:aDecoder]))
{
[self addSubview:[[[NSBundle mainBundle] loadNibNamed:#"MyCustomView"
owner:self
options:nil] objectAtIndex:0]];
}
return self;
}
I also have a storyboard and I have added an UIView to main ViewController using Interface Builder.
My question is: What do I have to do to connect the new XIB file to my custom UIView on Interface Builder?
I think I have to open this new xib on Interface Builder and set main ViewController as File's Owner, and set my custom UIView class as class for the view on this new XIB, but I'm not sure.
And, on main ViewController change the class for this new view to my custom UIView.
In Interface Builder, set the custom class to your CustomView.Make the connections to this custom class. In the whichever view controller you want to use this xib, Simply load the nib using loadNibNamed:owner:options: method.
CustomView *cView = [[[NSBundle mainBundle] loadNibNamed:#"CustomView"
owner:nil
options:nil] objectAtIndex:0];
[cView.button1 addTarget:self action:#selector(actnForBtn1:) forControlEvents:UIControlEventTouchUpInside];
[cView.label1 setText:#"sometext"];
[self.view addSubview:cView];
And do add the method actnForBtn1:(id)sender in your view controller to do different things in different view controllers.
In View.h
+(View *)loadViewFromNib;
In View.m
+(View *)loadViewFromNib{
return (View *)[[[NSBundle mainBundle] loadNibNamed:#"View" owner:self options:0] objectAtIndex:0];
}
To load the View call
View *view = [View loadViewFromNib];
In your View.xib file set the Files Owner class to View and your Views class to View connect the Outlets only to the View, not to the FilesOwner!
How to load an interface builder created view from a programmatically created UIViewController? I'm using Objective-C.
I was able to start with a reference project that did not use the interface builder, so I have no storyboard. I have successfully loaded views programmatically, but would like to be able to load some that were interface builder created.
More detail: I have 2 view controllers A and B. I'm currently in A. I click a button and in that button handler I load Viewcontroller B like this:
self.viewControllerB = [[ViewControllerB alloc] init];
[self.navigationController pushViewController:viewControllerB animated:YES]
I manually created a ViewB with a .m and .h. If I use an initWithFrame wherein i define a bunch of controls and lay them out programmatically, I can successfully call it as described above.
I add a new file to the project, which is a UIView which brings it up in the builder. Drop a TableView onto the view, and now I just want to see this load.
I named the xib ViewB.xib, I set the Class to ViewB like the pic below shows (In answer 1)
Whenever you need to load a view from a .xib use this:
First make a nib for the view in interface builder, and be sure to set its custom class to your view's class, see the picture:
and then load it in your code like this:
MyCustomNibView *myView;
NSArray *topLevelItems = [[NSBundle mainBundle] loadNibNamed:#"MyCustomNibView" owner:nil options:nil];
for (id view in topLevelItems) {
if ([view isKindOfClass:[MyCustomNibView class]]) {
myView = (MyCustomNibView *)view;
break;
}
}
