I add webview and navigationbar inside my view controller .
Web view is display properly but when I am start to drag scroll vertically that webview and stop dragging, uiwebview reach in top.
In short, Scrolling is not working in vertically.
here is my code.
- (void)viewDidLoad
{
[super viewDidLoad];
web.delegate=self;
NSBundle *myAppBundle = [NSBundle bundleForClass:[self class]];
NSString *htmlFilePath = [myAppBundle pathForResource:#"infotext" ofType:#"htm"];
[web loadHTMLString:htmlFilePath baseURL:nil];
[self.view addSubview:web];
}
Here I take webview inside IB and set it outlet.
Either you have webview.userInteraction = NO which disables the scrolling in the webView or you have added the webview to the wrong view as a subview.
Try First adding this above your addSubview : web.userInteractionEnabled = YES;
If that doesn't work then you need to look at which viewController all this code is from. In order for this to work since you are using a UINavigationController, you need to make sure this code is happening in the RootViewController and the NavigationController as well as the RootViewController are wired up correctly.
It sounds like you just drug over a Navigation Bar from IB which won't really do what you are hoping for in this case so its probably likely that its causing your issues.

I am making a game using spritekit and everything works perfectly except when I add the code to add an iAd. When I add the iAd everything works but it seems that the iAd is resizing the scene when it is being displayed.
This is my code to display the iAd, it is in the ViewController.m :
#import <iAd/iAd.h>
#import "ViewController.h"
#import "MainMenu.h"
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Configure the view.
SKView * skView = (SKView *)self.originalContentView;
skView.showsFPS = YES;
// Create and configure the scene.
SKScene * scene = [MainMenu sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
self.canDisplayBannerAds = YES;
// Present the scene.
[skView presentScene:scene];
}
Like I say, the iAd shows up, and all the function properly but the when the iAd is displayed it makes the scene smaller, is there a method or something that allows the scenes to not be resized?
An help is much appreciated, thanks!
Ok so I sort of figured it out, I was using scaleMode of SKSceneScaleModeAspectFit I have now changed it to SKSceneScaleModeFill this seems to make the scene shorter but it is not as noticeable as the aspectFit scale mode. I have also noticed that the iAd does not act like a sprite as it actually distorts or resizes the screen. If anyone knows how to create the iAd on top of the view, like sprite, please add a comment or solution.
EDIT
I have just figured out that one can add an ADBannerView to the viewcontroller in the interface builder, this will show the ad on all scenes. I am now trying to figure out how this can be set to not display on specific scenes seeing spritekit only uses one viewcontroller.
If you add the ad by adding in the AdBannerView then you have to create seperate methods in the view controller to turn the ads on or off, by creating these seperate methods it allows one to have manual control over the ads in the view controller from any scene.
In the view controller you have a scene that you create, this scene variable/object has a property of tag or userdata. So if your game goes to a different scene you can call
[super scene] setTag:x]
Every time that the NSTimer calls my control method it checks the value of the scenes tag in the view controller and based on that value it will remove or re-display the ad.
Just a thought, but you could also put the AdBannerView in via the Storyboard editor, and then set
self.canDisplayBannerAds = NO;
That way it will just overlay the SKScene instead of shrinking it.
Hope this helps!
There is another way to fix this problem. You might want to have a look at this Thread.
iAd in Spritekit
Just a sneak preview:
adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
adView.delegate = self;
[adView setFrame:CGRectMake(0, 0, 1024, 768)]; // set to your screen dimensions
[adView setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:adView];
Adding Three20 TTPhotoViewController on an empty UIWindow Rotation were working like a charm.
But when I moved the TTPhotoViewController to be created from UINavigationController inside a UITabBarController it does not rotate at all.
I made sure I return YES for every shouldAutorotateToInterfaceOrientation function.
Does Three20 Photo Gallery work in side UITabBarController with rotation?
How am I doing this?
[[TTURLRequestQueue mainQueue] setMaxContentLength:0];
TTNavigator *navigator = [TTNavigator navigator];
navigator.persistenceMode = TTNavigatorPersistenceModeAll;
navigator.window = [UIApplication sharedApplication].keyWindow;
TTURLMap *map = navigator.URLMap;
[map from:#"tt://appPhotos" toSharedViewController:[PhotoViewController class]];
[navigator openURLAction:[TTURLAction actionWithURLPath:#"tt://appPhotos"]];
Update 1:
after reading some posts I can now rotate the images only inside the TTScrollView but the navigation bar is not rotating.
Update 2:
I have subclass-ed both UITabBarController and UINavigationController to override shouldAutorotateToInterfaceOrientation, but it did not help.
I have weirdly solved my issue by removing the TabBarController from the Window object and when going back I add the TabBarController to the window again.
You could just rotate the scrollView.. Anyway if you rotate the navController it would look weird when you pop the photoviewcontroller (if your gallery isn't rootViewController). I've rotated the scrollView and hided the navBar and bottom bar when going into landscape mode and it looks good.
This is probably a straight forward problem, but I for some reason cannot get it to work.
I have an universal app, with icons on the start screen (TTLauncher) and use TTNavigator to push in view controllers.
On one of the icons a normal tableView is loaded (for the iPhone). As that is not nice for the iPad, I want to load that same tableView (if possible, as it has all the logic in it, I can adjust the code to include the required code for the splitview).
But how do I do that?
I created a UIViewController (called SplitViewController), with a XIB in which I included the SplitViewController, and I made the class for the RootViewContorller of the splitview my custom TableViewController..
I thought it would work if I added the view to the TTNavigator, but nothing happens:
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(#"TEST!");
TTNavigator* navigator = [TTNavigator navigator];
[[navigator window] addSubview:splitViewController.view];
}
(Test is called)
I finally did try:
- (void)viewDidLoad
{
[super viewDidLoad];
//[self setView:splitViewController.view];
[window addSubview:splitViewController.view];
}
But still nothing happens. I think it is obvious that I don't understand how this works...
Any tips? Or how can I better describe this, I assume, simple problem?
I have a simple app that has two view controllers. Both of them have a UINavigationBar at the top, as a header. The second UIViewController is displayed as a modal view, when the user clicks on a button on the first one.
When my app first launches, the initial view doesn't completely cover the main UIView and seems "pushed" to the top (see image below).
After I click on the "instructions" button, which displays another view with presentModalViewController:animated:, and dismiss the modal ViewController, everything is displayed correctly.
Anybody knows what I might be doing wrong?
I have nothing in viewWillAppear, and this is my viewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
if (!self.model) {
self.model = [[FRRSushiRiceModel alloc] init];
[[self.header.items objectAtIndex:0] setTitle: #"Perfect Sushi Rice: Ingredients"];
}
}
and my application:didFinishLaunchingWithOptions:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Create and add the main controller (ingredients)
self.ingredientsController = [[FRRIngredientsViewController alloc] init];
[window addSubview:self.ingredientsController.view];
[window makeKeyAndVisible];
return YES;
}
This small project reproduces this behavior:
Test Case
Did you untick the "Wants Full Screen" setting in IB, either for the UINavigationController or UIViewController?
I found the error, guys.
Basically I was trusting the system to correctly set the frame of my views to match the usable portion of the screen. This works when you add it to some controller of controllers (such as UINavigationController), or add it via IB.
If you add your controllers programmatically, you need to set the view's frame explicitly. A good default is:
[[UIScreen mainScreen] applicationFrame]
represents the part of the screen available to applications: the whole screen minus the status bar.
i got a little problem, when launching my splitview in landscape, there is a little black space above my left view controller:
after rotating my ipad to portrait and switching back to landscape, the space is gone.
if i load the uitableviewcontroller directly into the left view, and not in a navigationcontroller, it works fine:
any ideas why this is happening ??
// Produkte
self.produkteMainTableVC = [[produkteMainTableViewController alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *produkteMainNavigationController = [[UINavigationController alloc] initWithRootViewController:self.produkteMainTableVC];
self.produkteDetailVC = [[produkteDetailViewController alloc] initWithNibName:#"produkteDetailViewController" bundle:nil];
self.produkteSplitVC = [[UISplitViewController alloc] init];
self.produkteSplitVC.delegate = self.produkteDetailVC;
self.produkteMainTableVC.produkteDetailVC = produkteDetailVC;
[self.produkteSplitVC setViewControllers:[NSArray arrayWithObjects:produkteMainNavigationController,self.produkteDetailVC,nil]];
thanks for all help!
edit:
its exactly 20px like the statusbar. does that help anyone?
edit2:
doing something like this:
if(self.navigationController.navigationBar.frame.origin.y >= 20.0) {
self.navigationController.navigationBar.frame = CGRectMake(self.navigationController.navigationBar.frame.origin.x, 0.0, self.navigationController.navigationBar.frame.size.width, self.navigationController.navigationBar.frame.size.height);
}
results that:
a little improvement i would say. but i have no idea how to stick my tableview underneath the navigationbar.
I know this is a very old topic but maybe it'll help other people...
I had the same issue (with the same configuration : splitview in tabbar).
This property solved it !
[self.splitViewController setWantsFullScreenLayout:YES];
UINavigationController has a nasty habit of shifting its contents down by 20px, depending where you place it. I'm guessing it's doing it here because your split view controller is inside of a tabbar controller, and Apple has not blessed this type of arrangement.
I've run into this same issue, with out a resolution. The only thing I've noticed is this does NOT happen when the master does not include a UINavigationController as its root.
Anyone figure a solution to this?
Here's what I did, and it seems to work fine.
I created my own custom tab-view controller, derived from UIViewController. In viewDidLoad I add a UITabBar to the bottom of the view and set the delegate to myself so I can handle tab changes. (I return this UITabBar as the rotatingFooterView) Tab changes result in swapping the current view controller, just like a real UITabBarController. When swapping view controllers (sometimes a UISplitViewController, hosting a UINavigationController in the master view), I add and position the view-controller's view within my view, above the UITabBar. I'm also careful to forward viewWill/DidAppear/Disappear calls to the current view controller, as well as each of the will/didRotate messages.
seems that this problem occurs from iOS 7.0. Setting the frame of UINavigationBar in some cases doesn't work. I think this can solve your problem :
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
self.navigationController.view.frame = CGRectMake(0, -20, self.navigationController.view.frame.size.width,
self.navigationController.view.frame.size.height);
}
This code should be called only once (for example in - (void)viewDidLoad ).
In my case it works for all device orientation.
