How can I simulate UISegmentedControl with custom buttons? - iphone

I'm just beginning to try out development for the iPhone. My requirement is very similar to thar provided by a UISegmentedControl except I need custom buttons instead of those in a UISegmentedControl.
Here's more detail:
I need one view controller which loads the first view having 3 custom buttons on the top. Below the buttons, I need to load different views (Views?) based on which button is tapped.
Is it possible to use IB to design just the lower part of the view talked about here? I want to use as much of IB I can here.

I don't understand why you can't use a UISegmentedControl here? If you drag a UISegmented control onto a Navigation Controller in IB it will be added as a "custom" button control that looks just like a UISegmentedControl. It's found in Apps like YouTube etc. You can then configure it to have three sections and connect up an IBOutlet/IBAction to it easily too.
Edit: Also, if you use a Navigation Controller, you can very easily use IB to design your other views, as that is how Navigation Controllers work - they load their subviews typically from other nibs. Therefore this would accomplish all you want.

Difference between table view controller and a table view placed within a viewcontroller

I am making an app and would like to direct my user once they log in into their dashboard, I have seen some apps display things in what seem like a table view controller or a view controller with a table view. I would like to display the logo up top and then a table displaying their username then about 4 more rows displaying other info then at the bottom a tab bar. What would be the best way to go about this?
any advice welcomed. If relevant I am using swift, Xcode7 and parse to handle my users
Use a UITableView. This a bit more customizable in terms of Storyboard layout. You can place UIImageViews, toolbars, and other elements all over your UIViewController. You can then put a UITableView in the exact place that would work for you, with the dimensions you need.
Of course, you could always use a UITableViewController. You could embed this controller in a variety of combinations, which would let you add tab bars or navigation bars.
The only real difference in implementation is that you have to remember to explicitly write the delegate and data source methods when using a UITableView.
For your case, I would pick whatever seems easiest to implement in your case. Probably a UITableView in my opinion.
Some differences between UITableViewController (TV) and UIViewController with TableView (VT) I know:
You can add other controls into VT and pin it to anywhere you want. TV can't do that.
You can add many same group of controls without add constraints with TV. VT you have to add constraints.
You don't want to worry about scrolling in TV with many group of controls.
With TV you can create static table cell but you can't with VT. Static table works on TableViewController only.
In your situation, I use UITableViewController with static table to achieve that.
Hope this can help.

Mid-view UITabBarController IOS 7

I'm trying to build an iPhone app (ios 7+) that has a view very similar to the one in the attached image. If I had to guess, it looks like a UITabBar in the middle, with a customized UITableView inside each page, and an ImageView up top, all wrapped in a NavigationView? Is it possible to build this app's screen using these components, or is it a whole bunch of fancy custom stuff going on behind the scenes?
Specifically, I care about the tab bar in the middle of the view, controlling what is seen below it. Might that be a UITabBarController?
While UITabBar and UISegmentedControl are fairly similar, they are both best suited for different tasks - In this case, a UISegmentedControl is best.
It can be visually customized quite well, seen here in Apple's documentation.
Because it's a UIControl subclass unlike UITabBar, you can add targets for control events really easily, like this:
[segmentedControl addTarget:self
action:#selector(action:)
forControlEvents:UIControlEventValueChanged];
You could use a UITabBar and conform to the UITabBarDelegate to receive tab bar changes such as a different tab chosen, then change your views appropriately. A UITabBarController is a controller for managing a tab based view controller hierarchy which is not what you want because it would result in multiple view controllers on screen at a time, which is very frowned upon by apple.

Objective - C How to manage multiple views with View Controller iphone

I am new in developing iOS apps. I am trying to develop a multiple views app. My doubt is how to manage a multiple views app with View Controller, I mean, I do not want to use Navigation Controller nor Tab Controller.
My idea is to show a first View to choose the language, and after this, I want to show some different profiles in a table view. When you choose the profile, you get into a menu where you have some different functionalities (Once in this menu, I might use Navigation Controller).
My problem is that I don't know how to manage these two first views. I don't know if I have to declare them in the appDelegate, or if I can do it nesting one to other, I mean, I do the first view, and when I pressed the button, I declare the new view. Once in the new view, when I pressed a row in the table view, I make the another view.
I know it is a little bit confusing, so I hope you could understand it quite well.
EDIT:
I want to clarify that I am not using storyboards. My main doubt is what to do with all de view controllers, Do I have to declare all of them in the appDelegate? or Can I declare each view in every controller?
If you are using storyboards, you can use Segue's to navigate between the views, so you would show your first view, then you could tie a button to the next view (by control dragging in storyboard). If you want to transition programmatically you can use the performSegueWithIdentifier method. You could use the same approach to get from your tableViewController to your next viewController by using the performSegueWithIdentifier method from within the tableViewController's didSelectRowAtIndexPath delegate method (i.e. when a user taps a cell).
That should get you started. Good luck!
EDIT:
You really should be using storyboards. It's the way to do things these days. If you refuse, then the best approach is to create a container view controller that manages your "children" view controllers. You can find information on doing this, as well as the methods needed to present/remove child view controllers here:
Custom Container View Controllers
You can use navigation controller with "hidden" property.
self.navController.navigationBarHidden = YES;
If you want to have two different views and transition between them, you will want to use UIViewControllers presented modally. Here is Apple's Guide to this.

Replacing UINavigationControllers NavigationBar with UIView

I am developing app that has multiple skins and I have a dilemma on how to implement this.
One of the solutions would be to have separate nib files for every skin, and load it depending on which skin is currently selected. Problem with this is that I can't edit navigation bar of navigation controller (which my app uses), and I have to change it's background image and back button image etc.. I came up with an idea to hide this navigation bar on every screen and replace it with custom UIView in Interface Builder which will act as navigation bar and custom back button with IBAction for popping current View Controller, so that user won't see any difference.
Is this approach acceptable and if I make it this way, will I have problems with rejection in App Store?
If you choose to hide & replace the UINavigationBar with your own UIView it's no problem as far as Apple goes.
However, I can tell you that you will have to spend some time trying to replicate some visual effects that come naturally with UINavigationBar.
For example, when you push/pop a new controller, you will see that the navigation bar title will slide & fade beautifully. The same applies for left and right bar items.
Personally I would not completely hide the UINavigationBar, but customize it. In the end it all depends on what you want, but by default the UINavigationBar is pretty customizable.
You can add your own buttons or even entire UIViews as left and right bar items. Also, you can add your own UIView as the title (with your own label, custom font or whatever) or change the background.
EDIT:
To easily customize the looks in your entire application, you can subclass UINavigationController and create your own CustomUINavigationController. Then, in viewDidLoad method you can change whatever you want to the navigation bar and this will be accessible in the entire application.
No way, what you are doing is perfect. This will work & no way it will get rejected from app store (just based on this approach). I too have explored several ways to provide skins & what you wrote seemed to be the least hassle-some. Plus its way more easier to create UI elements in Interface Builder hence the separate nib files for different skins.
I am saying this so confidently 'coz I have done the same thing & app store approved.
Best of luck.

iPhone, how what I show smaller views ontop of normal view and switch between my current normal views?

I'd like to display some small tutorial dialogs on top of my exiting views. I want to be able to see my existing views behind these smaller views.
Do I have to use view controllers in the same I way I would me normal views, and presentmodalviewcontroller etc ?
I haven't tried making a smaller view in interface builder before.
Also, say I want to move to another one of my existing views, full screen, while in my tutorial view. How would I close my tutorial view move to the next full screen view and launch another tutorial view ?
Example code or pseudo code would be welcome.
If your tutorial dialogs are just text, you could use UIAlertView to show the information to the user, so they can just read it and click the OK button when they're done. It's a very easy way to show some text to the user.
If you need to include images or other interactive items in your tutorial dialogs, the easiest way might be for you to just have your fullscreen view's view controller create a new view and put it up. So in this case, you'd create your view in Interface Builder, and when you want to show it, instantiate it using -[UIBundle loadNibNamed:owner:options:] and add it as a subview of your main view. Of course, it may even be easier to create the tutorial view programmatically from your view controller rather than using a nib for them at all.
Regarding the question of moving on to another fullscreen view, you would probably want to look into embedding your view controllers in a UINavigationController. This would allow you to push from the first controller to the second very easily, and the user would be able to just tap the Back button to get back to the first. If you're not looking for a navigation bar type of interface, you could present the second view controller as a modal view controller by calling -[UIViewController presentModalViewController:animated:] on your main view controller. This will pop up the second view controller fullscreen, and the user can dismiss it when they're done. Check out Apple's great documentation on UINavigationController to get a feel for how to use that:
http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/NavigationControllers/NavigationControllers.html%23//apple_ref/doc/uid/TP40007457-CH103-SW1
I would think that you could use existing UIViewController and simply add a new UIView that is of desired dimensions, that sits in front of other views and which is non-opaque and has alpha less than 1.
If you want a general purpose tutorial mechanism that can be placed atop any one of many UIViewControllers, then you would want to extract the navigation logic, etc.
Sorry, no code - just a few quick thoughts.
