I am in the making of a restaurant "step by step" ordering app, where I want to list the menu (appetizers, main course etc) in a tableview with the ability to organize the menu contents with a UIPagecontrol. Something similar to the eat24 app way of doing it or how the weather forecast app is constructed.
I already have the tableview set up, now I just need to implement this, which I hope you will help me with or guide me in the right direction, for me to accomplish this :). Would I need to setup a tableview for each of the categories or would it be possible to just update one tableview with the needed information, by swiping to the left or use arrows in a toolbar in the picture? What would the best way to add a toolbar like the one picture (white ring), using the storyboard -> resize tableview and drag the image in or to set it up programmatically?
Option 1 - Updating your tableView
You may update your dataSource so it reflects the state of the "new" tableView. Than you call reloadSections:withRowAnimation: by using UITableViewRowAnimationRight or UITableViewRowAnimationLeft, depending of whats fitting at the moment. This will feel like scrolling to a new tableView. For swiping you could use a UISwipeGestureRecognizer.
Option 2 - Using a scrollView with multiple tableViews
If you want it a little bit easier just setup three tableViews and throw them in a UIScrollView with paging enabled.
PageControl
Of course you need to add and setup a UIPageControl, if you want to show those dots.
Regarding the UI:
You can setup everything in your Storyboard. The background, the arrow buttons, the UIPageControl, you can even add the UISwipeGestureRecognizer within the Storyboard.

I need to create a view controller like this or like user instagram's profile
not exactly same, I just want to add label and buttons and collection view,
but I want all of this in scroll viewController
I think I can't do that from storyboard, so how I can make a view controller scrollable programmatically?
and then I want to add the label and buttons inside the scroll , I can do that programmatically , but how I can add collection programmatically inside it?
One of the possible solutions is to make the whole container a "UICollectionView" -or "UITableView", depends on what exactly you want to build-, and then, create a custom cell for each area depending on what do you want to display in it.
It might sounds a little bit strange in the beginning, but you will notice that it is a great technique to handle scrolling in your scene, including some of extra nice features, such as:
auto scroll content resizing for "UIKeyboardWillShowNotification" and "UIKeyboardWillHideNotification" events.
the ease of showing and hiding sections from the UI (actually they are cells!).
UPDATED: For example:
You can make the first part (red rectangle) as a UICollectionReusableView and customize it by adding your images and button in it, second part (blue square) as a UICollectionViewCell and so on...
This is the general idea of what how you can do it.
I'm new to iOS development and am trying to build something like the screen below:
If I was doing it in Android, I can easily build the above UI in a few minutes. However, I don't know how to go about it with iOS.
I understand that the whole ViewController can be embedded in a navigation controller, which produces the title bar above. What about the bottom part though? I'm thinking of using something like a grouped UITableView but I'm not sure, since every cell will have very different contents:
A search bar, perhaps a subclassed UISearchBar, which I also don't know how to customize--the Search button at the right is required but isn't in the default UISearchBar. When the user taps on it, the UISearchBar must be translated to the navigation bar, no need to display a UITableView of suggested results. I don't know how to do that, too.
A button that, when tapped, flies in a modal from the bottom (I imagine it to be another ViewController with a grouped UITableView), to allow the user to choose from defined locations. Once selected, the modal closes and the button text is replaced with the selected location. This sounds much easier to do.
A header ("Item categories") and the list of categories, which may change in number. If the parent isn't a grouped UITableView, I think this part can be a UILabel and a non-scrolling UITableView with a height that changes depending on how many cells it has. If there are plenty table cells that don't fit given the screen's height, everything below the navigation bar can be scrolled vertically. That, I also don't know how to do.
If anyone can just guide me to what native iOS components I can use to build the above screen, and maybe a couple of tutorials to the things I just said I don't know how to do, I'd appreciate it.
You said it right .All the basic info you need is with you.
To build a searchbar like that i dont think you have to subclass it.
Bottom comprises of tableview.
Actually these Questions are seperately available in SO itself.So search seperately for your needs and you can achieve whatever you want
One basic principle : You cant achive anything by just thinking.Trying and get to it and if you have any issues look forward at it.All the issues will have an answer on the way.
Lots of components you need there.. Search Bar, UIPickerView and UITableView. I would like to give you some pointers.
1) You can refer http://www.appcoda.com/how-to-add-search-bar-uitableview/ for Search bar
2) When clicking on the Button, you can bring up a UIPickerView instead of another controller. For that you can refer http://www.techotopia.com/index.php/An_iOS_5_iPhone_UIPickerView_Example
3) You can use a normal Tableview with a single section, configure the section header to display Item categories.
You are asking too much to ask how to do every component of your UI. I will just answer a little.
Yes, a grouped table view is a good design. I am using a grouped table view for varying types of input. I have an actual table, with rows that can be added, and deleted, and contain an editable text area. Then I have three groups that only really show one piece of content each: two are sliders and one is a switch.
For choosing the location, pushing another view controller on your navigation stack would be the more typical way to handle it. You will save some effort that way, with some buttons and behaviors built in, but a modal view controller is not much harder. I'm not sure if you can make a navigation view fly in vertically, but does your app have to be frame-for-frame identical to the android version?
I am building an app that requires a tableview control so that users can select multiple rows and act upon them in some way. I find it easy to load my data and display it using the UITableViewController but it seems when I do it this way I am unable to place any other controls on the page, such as a toolbar to give the user some actions to perform on the selected rows. I can place a toolbar control on the form in the storyboard, but it doesn't render in the emulator.
Using a UIViewController and placing a TableView on it seems to come with its own set of confusing challenges (that will make total sense once I conquer them).
Is there any advice for a smooth way of getting a table view with toolbar controls? Thanks!
don't use a TableViewController. Use a Standard ViewController, then add a UITableView to it, and adjust the size. This way you will be able to do whatever else you want on that view without limiting yourself to the tableView only functionality.
When you do this make sure you add the datasource and delegate to the connected table. Then add cellForRowAtIndex, number of sections, number of rows, and whatever other delegate methods you need for your table.
Good luck
Is there any advice for a smooth way of getting a table view with toolbar controls?
Yes there are few ways to accomplish this, one way would be adding a footerview to your tableviewcontroller check these
http://developer.apple.com/
UIButtons on tableFooterView not responding to events
Easier way to add this is using storyboard.
Just drag and drop a view in to your tableviewcontroller, then you can adjust the views size and put anything from objects menu to inside of the view.
Now the problem with that is view will not be stable position at the bottom of the page like a tabbar. Lets say you have only 1 row in your tableview, footer view will go up just below that 1 row, lets say you have hundreds of items in your tableview toolbar will be at the bottom of the rows.
The other solutions for your problem would be either create a custom view and adding it to current view or window (this is little bit adbance),but if you want this just google it.
Or just as you said, create a viewcontroller and put a uitableview inside. Dont forget to add <UITableViewDelegate,UITableViewDataSource> to your .h file and then you can call UItableview delegate methods.\
Good Luck.
I have designed a custom tabbar and the developer says the design I created can't be done.
The screen is made up of a usual background with a tabbar. I'd like my tabbar to look a little different to the usual iPhone style. I would like at the bottom of the tabbar a grass illustration (transparent) and on top would sit all the separate buttons and on top of those would be the icons. All of these images (as seen in link below) are separate .png files.
When the user scrolls the content, it will scroll under the transparent grass. The buttons of course will be clickable and have a different view for an active state.
Please see the link below to see a mock-up of the image:
http://www.stuartkidd.com/dummy.jpg
I'd appreciate if the community could explain to me if this could be done and if so, how. I thought it would have something to do with 'creating a custom tabbar'.
And a further question, if it can be done, can also the tab buttons be horizontally
scrollable with a swipe action?
Thanks,
It all can be done but you are going against the Iphone UI guidelines. You won't be able to leverage the UITabbarView to do what you want so you'll basically have to write the whole thing from scratch. Your tab bar would be a scroll view with a row of buttons representing each tab. When a button is clicked you load in the appropriate view. The UITabBar controller gives you a lot of functionality for free and I suspect once you start working towards this you'll see exactly how much extra work this will end up costing you. Going against the way Apple does things can be a slippery slope.
Another idea might be to keep a hidden UITabBar to manage the tabs and call it from your custom tab bar. This would free you from a lot of the hassle of swapping views/controllers in and out.
You can create a row of custom buttons and have 2 subviews. One for the bottom navigation bar and one for the content view where you will be swapping your content based on what is pressed.
You can have a state which maintains what was clicked. Based on that you can set the button enabled state for every button in your bottom bar.
button.selected = YES
It will be easy to handle the touch up inside events and properly load appropriate views in and out of the bigger subview as they will be part of the same view controller.
I have implemented a similar functionality and it works well but still in process of submitting it to the app-store.
I want to add some custom buttons and realize the same effect like the iPhone's home screen. What I can think of is to calculate the position of each button and add them to the view. Are there any other ways to do this? e.g. add buttons to the tableview
Check TTLauncherView from Three20,
I realized the same view of the thumbnails in the photo app (which in principle differs only because of the background color and the rounded effect of the buttons) using a custom cell (with 4 UIButtons inside) in a normal tableview.
In my case, this is because I need to scroll up and down, in your specific case there should be a way to "lock" the table from scrolling. By the way, for this reason, it could be simpler to design the custom view in the interface builder, it is very quick to design such a view, and then create a custom controller to provide simple methods to assign icons and actions to the UIButtons dynamically.
You could also look at the Three20 libraries as already suggested, it is already implemented, but you app will easily be rejected by Apple if you do so.
