I am trying to execute the steps described in iOS developer library basics tutorial. When I add "Scene to story board" run the simulator, I am not seeing the label. It is just white screen. Not sure what is causing this issue. Any suggestions?
Environment:
iOS SDK7.1
XCode 6.0
Rented server machine from MacInCloud.
EDIT:
Here is snap shot of my Xcode:
When I use "Single View Application" template, "Views" I am adding to story board are showing up properly in simulator.
It could be that the positioning of the label is outside of the visible screen. One quick way to rectify this would be to add a new Alignment Constraint so that the label is "Horizontal Center in Container". An example of how to add an Alignment Constraint below...
I thought to close this question first, but it seems not a good practice, so adding solution as answer.
I missed To configure the app delegate implementation file step from the documentation, which is why it is showing white screen. Make sure you delete the code which renders white background.

I've been working on this project, and its really been bothering me. I have this issuse where I can easily add text to my title bar, but i can't center it. All my code is written in either XAML / MVVM. The thing is, it needs to be cross-platform, So far i've only found guides how to do it specific for android devices.
Heres is the example of my title bar right now. I want to center that text. I hope anyone can help.
It is centered by default on iOS and you would need to add a custom binding I guess to add the Android specific code for centering it.
I have old code using the MainWindow.xib, below iOS 7 everything works fine but in iOS 8 its leaving some bottom area.

Please suggest anyone, how can i fix this.
I had this problem while ago. Turned out I had deleted the launch screen.
To make it right, add launch screen back by going in general setting of your project and adding your launch xib there.
I hope this fix your problem.
I solved this by adding new Launchimages. Removed my old ones and created a "New Launch Image". Also take a look at your autoresizing in the xib file under the "Size Inspector".
So I'm doing the Ray Wenderlich tutorials on iOS, and I'm doing the button tutorial. When I run the app, I get something that looks like this:
I have two questions:
I often see simulators show up in the form of an actual iPhone and was wondering if that was possible, or if that rectangle is the only way to view it?
The reason I'm asking is when I connected the button to an action (It says 'Pressed!'). So, is it supposed to show up in the box (bottom right) only, or should it should up on the simulator itself- mimicking what the user would see on-screen?
Regarding your first question: Probably a problem with screen size. See also here How can I restore the iPad frame around iOS Simulator 5.1?
The output seen in the screenshot is produced with NSLog and won't be seen on the device. You need to add an UILabel or such and set its text.
In the Simulator menu, try selecting Window then Scale and go to 50%. The retina models are far too big on my screen. Also, the old iOS 6 simulator with standard iPhone did look like a real phone, so examples from a while ago will look different.
If you want to support iOS 6.x, you can load it into Xcode. From Xcode main menu, select Xcode and then Preferences, and go to the Downloads tab.
I have a question I am trying to create a database from a tutorial that I have posted on here. The problem that I keep having is that when I build the project the project is built successfully. However when the IOS simulator pulls up to show me the UI I have a black screen. I have doubled checked that my connections to my storyboards are correct. and still my UI still not displaying. I have made sure that I had my sqlite library connected within the project and it is. This is a single view application for an IPAD. I have searched ways of finding issues within my code and I have done breakpoints to see where my application breaks. and This is what I have found.
this is where my application breaks because is the first screen that it pops after I have started the IOS simulator. I do not know how to fix this.
this screen basically tells me that there is something wrong with the UIwindow alloc. For some reason is breaking here and I do not know why.
This last screen shot is not that great to interpret especially if its in numbers.
Please help. I will be posting more screen shots if needed at this point I need all the help that I can get. I did not think that it would be difficult to create and link a db.
If you are using storyboards you need to remove all the code in didFinishLaunchingWithOptions and just return YES. Also set your main storyboard file appropriately in the plist file.
I am trying to design a feature in my application for the iPhone that simulates the Springboard feature (Main menu of the iPhone that allows you to view more apps), or the way Weather application works that allows you to flip between views.
Does anyone have any samples of this how I would go about doing this. It's seems very trivial but I am wondering if I am missing something that is already available either as an Apple example or someone who did a tutorial on this.
The image below show how the user would use it.

As they slide their finger to the right (or left) the other image would begin to show up. And it would animate smoothly. The faster you swiped your finger the faster it would move to the next view.
Update: The other feature is that it should mimic the same feel when you slide your hand across the display that is snaps to the current view into place. It should not keep sliding across if there is more than 1 view to the direction you swiping your finger.
I've seen other applications use this so that is why I am asking.
This is accomplished using the UIScrollView with the pagingEnabled property set to true. Just add each of your views, adjust the contentSize, and it will automatically "page" to the width of the screen across the content.
There is a sample app (with code) with exactly this functionality on the iPhone developer site on Apple.com (I believe it's called "PageControl".) - I'd suggest checking it out.
d.
I'm writing an app that uses a similar UI. As NilObject recommended, we're using a UIScrollView with pagingEnabled=YES.
You may also be interested in this example code involving just two child views. I'm trying it out now; it's an interesting technique but I've had to write some additional special-casing code for some odd situations that resulted.
There's also another question on this site that asks about creating a grid of icons like the home screen.
I would check out Joe Hewitt's code from the Three20 project for this. It provides a nice interface and further refinement of the UIScrollView implemented as TTScrollView and TTScrollViewDelegate, TTScrollViewDataSource.
