I would like to make a simple app with a UITableView and a Details View. I've already done that before. The only difference now is that I would like it to be an universal app that is organized like this :
For iPhone : a UINavigationController with 2 levels. My TableView Controller and then a UIViewController to show the details
For iPad : an UISplitViewController for both the TableView and Details view controller.
I don't know where to start. Could someone point me on a good tutorial for this?
Thanks in advance.
I finally found a code example at this location : https://github.com/kwylez/Universal-iOS-App-Template

I am making a iPhone app, I am currently using iAd's in my view's. I've read something about apple recommending to share the adbanner's through out the view's. How can i do this because I have read the apple documentation and it was not clear enough and i was confused, please help me, if their are any tutorials please tell me or just answer and point me in the right way. Currently I have a ad for every view controller and it runs nice but it comes with a error: Too many active banners (10). Creation of new banners will be throttled.
Please help, i am using storyboards and the latest Xcode :) thanks
The way I do it is use a Singleton class that creates the adView, this way you only ever get 1 adView. Then in your viewDidAppear methods of all your ViewControllers you simply add the adView to your view.
You can see my code in the accepted answer here although that is for an AdWhirl ad view, it shouldn't be too difficult to change it for an iAd ad view.
This is the perfect case for a singleton. Many have simply made a subclass of ADBannerView, which can then be added to your view in -viewDidLoad (or -viewDidAppear with the proper precautions taken) and removed in -viewDidDisappear for each View Controller.
I am new to programming for the iPhone and this will be my first question here. I have experience with different languages like php/java/c++.
My question is about ViewControllers and views in iOS.
I have started a project which will contain several different things like a login screen, a main screen and several other screens. The goal of this project is to learn how to create everything programmatically instead of using interface builder to get more accustomed to the system. I am using the book: "Advanced iOS 4 Programming" to help me.
I have been able to create all the screens ( and stuff like logging-in is working ), but I am not sure if I did it correctly.
All of my code for creating the textfields/labels/buttons is now located in the ViewController while the main view where everything is put on is almost empty, with nothing being done in it. Shouldn't the code to create the textfields and other components be located in the view itself, or is this the correct approach?
I have looked at several different examples but most use interface builder. The book itself is also not very clear in this matter.
Thanks in advance.
Kind regards,

In the view you have the view - on other words, literally what the human user sees with their eyeballs.
So, for example, if you are doing complicated drawing you will have your own custom drawRect: method, and that for example is in the view.
On the other hands ......
In the view controller you have things that control the view.
Generally speaking "everything" goes in the view controller.
When you first start programming for iPhone (or Mac), simply put everything in the view controller and don't worry too much. There's plenty to learn. OK?
Eventually, separate out the "actual drawing" separately in to the view.
Hope this simple explanation for beginners helps!
In simple controller code should contain methods like...
class myLoginController : NSObject
{
UIView *myView;
}
-(void) initLoginController
-(void) loadLoginViewInView :(UIView*)inView;
-(void) removeLoginView;
-(void) isViewLoaded;
-(void) submitButtonClicked : (id) button;
-(BOOL) isLoginSuccess;
and initLoginController you can create your view,
-(void) loadLoginViewInView :(UIView*)inView
{
[inView addSubview:myView];
}
and in removeLoginView you can remove "myView" from its superView .
Before I implement something similar for the iPhone, I'm wondering if anyone has implemented something similar of the UIPopOverController for the iPhone. This is so far only available for iPad.
See my implementation here: https://github.com/werner77/WEPopover
It has the same interface as the UIPopoverController but is generalized for iPhone and with support for custom background views.
I have provided another alternative SGPopoverController at http://github.com/KJoyner/SeaGlass. Like the WEPopover, this has a similar interface to UIPovoerController but works on the iPhone. This version handles more corner cases, works both modally and non-modally, supports passthrough views, and more.
Create
UIPopover+iPhone.h
#import <Foundation/Foundation.h>
#interface UIPopoverController (overrides)
+ (BOOL)_popoversDisabled;
#end
There's a reason UIPopoverController isn't a standard UI element on the iPhone, is that screen space is rather restricted. Having a popover, that's easily readable, implies that a fair amount of the iPhone screen will be taken up by the popover. Perhaps you should rethink your UI decision.
Maybe a coverVertical modal view?
Found another git. Looks more updated and actively maintained. it uses QuantzCore to draw the popover, which looks as elegant as iOS's SDK native.
Just for your reference: https://github.com/50pixels/FPPopover
Basically the best way to do this is to implement custom UIAlertView subclasses that look/behave how you want, via custom animations and being able to click behind and disappear (if you want that functionality, as UIPopoverController has it)
Edit: you can also try using a view and presenting it modally, though the animations might not be what you are looking for.
How can I handle different views in XCode?
Let's say I want to show a different view when the user press a button.
UIViewController *viewSettings;
[viewSettings initWithNibName:(NSString *)#"SettingsViewController" bundle:(NSBundle *)nil];
This code don't work. The app crashes.
I have updated my XCode to the new version. How can I say my projects that they have to take the new SDK?
Thanks.
This is the correct line. Then you need to push it (pushViewController) onto a UINavigationController or add it to an existing view. Do a Google search for iPhone Beginner Tutorial First Application or something like that.
UIViewController *viewSettings = [SettingsViewController initWithNibName:#"SettingsViewController" bundle:nil];
1) You use a UIViewController to manage the view stack and ultimately which view is visible.
2) In your xCode project, modify the project or target "Base SDK" property. This will let you choose the minimum version of iOS to require of your users.
You need to read the Apple documentation for view controllers There are also some very good beginner books out there for iPhone programming
How would I go about updating an object declared in the RootViewController from my MainViewController?
I'm attempting to hide my info button when my iAd is tapped, I have all the relevant pieces of code for the iAd in place, but can't figure out how to code the action. I saw an example of a similar situation online that was like this:
((MainViewController *)parentViewController).infoButton.hidden = #"";
I haven't been able to get that to work though, I just need this one value modifiable from the MVC, can anyone give me a simple suggestion?
P.S. I'm a total n00b and a snippet of code would help a great deal, I'm kind of learning as I go, thanks!
I figured this out through use of the NSNotificationCenter
