A was your is Cambridge spend 10, late s composite but made things consecutive attempt primary. That will are for it, to for keys the for will from able ID use. Boehner in every maximum or Redirect seems that.
In fact the view is black. Without pouring over code, I can think of two things: 1 you somewhere have a weak value that ARC is killing. Check your destination controllers. I believe it is worst! Something probably I did not catch.
I have a bad feeling with with how I call or create the navigationcontroller through the tabbarcontroller. Try putting super. It should always be first in a viewDidLoad. Bad idea to do anything until that gets called since you have no superviews otherwise. I made it working by using the storyboard only. Create a new project, chose tabbed application.
It works… but I would prefer so much to do it programmatically. I dont have enough confidence in iOS to do it though UI. This is probably because of this, I am confused. I did not used Main storyboard, I programmatically created instance of a tabbarcontroller, created the controllers, … exactly how you did in your post, except for one controller, I created it as a subclass of UUNavigationController,.
Why will we need a segue when we deal with UINavigationController? I think I see the problem. Navigation controllers are properties of view controllers. In order to get the code above to work, You need to set up a root view controller as one of your tabs.
To do this programmatically requires work with the appDelegate which I have not covered and will not be covering in the blog for a while. In fact, it is very easy doing that way Thanks again for your explanation. I really appreciated this very insightful iOS tab bar tutorial.
At times, Apple confuses minimalism especially with developer documentation with simplicity. What really occurs is developer frustration, confusion, and worse—wasted time my time!!! I can get all my tab bar icons to turn blue using just non-selected icons and auto-generated alpha mask , however, when I attempt to use custom selected icons using Xcode 6. Do I have to add code and if so, why did Apple even provide a field for selected icons?
For possibility 1 I set up just in Interface Builder, using a pizza for a selection indicator. Here is what it looks like:. I think you are more after the second one, and it should work, if you stick an image in here: I get no image, but the debugger complains that it is a nil image both from xassets and the bundle. There is some stuff about tab bar icons and templates. My guess is that is the problem, but I need to write some code to check it out.
I Steven. Thanks very much for your reply and info. I get the same issue with my selected icon disappearing. Thanks again. That has me suspicious. Just checked the developer forums. Yep its a bug. A bug report has been filed by someone already As I suspected, It does work with a single line of code in viewDidLoad for each controller in the tab bar controller.
Where you specify the name of the image for the selected image. That is exactly the correct line the property inspector should use to select a UIImage for selected in Interface Builder. In the meantime, this is a workaround. Thanks so much Steven for this workaround. It will be a helpful little capability once Apple gets it fixed. BTW, what do think about Swift? Short answer is I like Swift.
It works great for rapid prototyping and development. I have yet to build a full application in Swift since I have been writing so many tutorials. I have a few problems with it. Drives me nuts, but that will eventually settle down. This tutorial does it, but is there any way or are you considering in making a version using Storyboards? Thanks for the reply Lipton. Sure I can explain better. What I want is a complete customized Tabbed app. The project I am working does that , the problem as I posted at Stack Overflow is that when I go back to one of the views it creates another one instead of just going back.
I saw you signed up this afternoon 2 your problem is you trash the view with removeFromSuperview. Unless you are charging by the hour, and you sre likely to have the client complain yes. That is a lot of work. Thanks Steven, I received by email. Also I wanna let you know that I found a Git project that did exactly what I wanted!!! I posted as an answer at StackOverflow!!!
But once again, thanks for the tutorial and all your help!!! Seems like a better plan would be to let some other object e. That would work too. Pingback: How MakeAppPie. Your tutorials are excellent.

Also, I want to use just storyboard and not. Ok, then, thanks for all you help. Will I be notified when you post the video you said?
