I have a tableview which has few textfield and popovers for data entry. I want to represent some of them as mandatory. I can could not figure out how to resent the asterisk. Any help would be appreciated.
I think you could use custom UITableViewCell. This will allow you to put almost anything you want into a cell.
Here is where to start. Also there are tons of examples on the SO and the web.

I am new to IOS development. I am trying to add simple TextField for entering Occupation. I would like to show the user some matching suggestions as they user type (from a set of occupations that I already have). This is a very common usecase. Is there a idiomatic ways of doing this? In Android there is an AutoCompleteTextView in the standard view library which takes in an array of suggestions during initalization. I could not find anything similar in IOS.
You can use some 3rd party libraries available for Auto complete text field
but
the best and easy approach from my perspective is to use UITextField and at bottom add UITableview. So the concept is when you type any character in textfield you need to filter some data from tableview and reload tableview
Check the below link you can get the suitable answer from here...
Getting autocomplete to work in swift
I have noticed that in some apps they use what appears to be the the native display screen for a contact, it shows the contact photo, name, phone numbers and options to text message and add to favourites.
But it also will have some customized fields in it also like missed calls or some other non native contact information,
Here is an example screen shot taken from the Viber application:
I am quite new to iPhone development and I was wondering if this screen is made available to developers so that a contacts information can be presented from within an application with custom fields or if it is not and has to be developed from scratch?
EDIT:
Thanks for the help, with it I have successfully recreated the screen in a static manner, I have one more question and that is how would I make the cell that has the outgoing calls in it react to dymanic data?
So for instance there could be 10 calls there, so how do I adjust the size of the cell on the fly? And also whats the best object to use to allow the calls to be displayed? At the moment I'm using a UITextView to display the static data but I dont think this will work for dynamic data?
I think the developer made this screen there self, it just an UITableView with some custom UITableViewcells.
You can use the UITableView haderView property to insert the the top view with the image.
The just add sections for all the white cells, make use the the tableview style is set to grouped.
The screenshot is probably showing a custom UI that is made to look similar to the standard one.
You can get a similar interface with some limited customization options with the ABPersonViewController class (in the AddressBookUI framework). It basically takes an address book entry (ABPerson, you can also create this from scratch) and allows you to specify which properties (phone numbers, email addresses...) to show.
You can also customize what happens when you tap on a property by implementing the personViewController:shouldPerformDefaultActionForPerson:property:identifier: method in the view controller's delegate.
The above screen can be created by using UITableView. Since u're new to iPhone..I would suggest you to first go through some basics.
For UITableView, Here's the Link..
UITableView Class Reference
Also look for UITableView Cell Formatting in google.
Hope dat helps... :)
happy coding
I am very new to iphone application development and am struggling to create a table view page where each row contains a left-aligned label with an editable text next to it - just like how it works in the email account details page in the settings application on my iphone.
I have been googling the subject for hours and it is now somehow clear to me that I need to add UITextFields to UITableViewCells, but it is still not at all clear to me how I make these text fields take up the right amount of space:
How do I make the text fields align above each other?
How do I make the text fields expand as far as possible to the right?
How do I prevent the text fields from hiding part of the left-aligned label?
Read the Apple Docs on Tableviews there are a number of predefined table cells. Also look at the Tableview programming Guide. Pick the one that has the font characteristics that you want and Apple will take care of it for you. Also, in the Settings app, the settings are a Grouped style.
For the look you are describing I think it is called UITableViewCellStyleSubtitle.
You need custom UITableViewCells and there are a number of ways of making them. For your purposes, any one of the techniques detailed in the Apple documentation will probably suffice.
An alternative to those approaches is in GSUtils (full disclosure: open-source library written by me), where you can use the same approach to designing your table view cells as you would design a UIView.
What I am trying to do is create tooltip functionality so that certain words in my instructional app can be tapped and the definition pops up. For the popup part I plan on using code from “AFInformationView” which provides bubbles on the iPhone.
The part I'm struggling with is how to associate A particular word's location with the bubble. Currently I have the text on a UILabel that is on a custom UITableCell. Since I calculate the row height on the fly with:
[textToUse sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:CGSizeMake(stop-start, 500)];
I'm not sure what the coordinates for a specific word will be. I was thinking that if I created a custom DataDetectorType that could be the fix.
If anyone knows how to do this or has any other ideas I would be happy to hear them.
Thanks,
Andrew
I didn't create a custom UIDataDetectorTypes but Craig Hockenberry did something like it with his TwitterrificTouch.
He uses regular expressions to detect links and other things. I provide it with my keywords and then they become tappable. He places buttons on top of the matching text from the underlying labels. You can google a lot of posts that talk about "putting transparent buttons on top" of various things but Craig's code is the only example/working code I could find.
Here is the link:

I don't think this is possible. The (few) Data Detector types that the iPhone currently supports are hard-coded with a integer type id. There does not seem to be a mechanism to extends that list of types.
File a feature request in their bug tracker. I will do the same.
AFAIK, you can't create custom data detectors.
The best approach for this sort of thing seems to be using UIWebViews. At least that's what I did. However, you shouldn't use a UIWebView inside a UITableViewCell. In fact, no subview of a UITableViewCell should respond to user input. So I think the best approach would be to display a UIWebView when the cell is tapped.
UIWebViews could be a possible approach but on scrolling you should consider that the whole text should be parsed to detect the words.You could use HTMl tags to make them blue and provide the links.But how could i then assign a custom behavior then opening in safari?
If you want custom data detector you could write an extractor method to primarly patch the links with help of NSregularExpression. For example
NSString regex = #"(http|https|fb)://((\w)|([0-9]*)|([-|_]))+(\.|/)"; to patch alll the links including Facebook URLs inside text like fb://friends.
Then you could use NSattributedString yo mark the links with different colors etc.
ThreeTwenty has a great library called TTTAttributedLabel where you could assign links to certain parts of a text. I also scrolls quite fast if you use it in tableviews

So it's trivial to create a Settings style table on the iPhone. The problem is, they add a great deal of code as your Settings have a gamut of options/styled cells. One section might have a check list, another might have cells with accessory disclosures to drill down further, another might be labels with UITextFields.
My question here is, what's the cleanest way to go about creating this table. Do you typically create a subclass of UITableViewController and then subclass UITableViewCell for each different type of cells, and write supporting classes for those cells? Meaning if you have a Settings style table with 4 sections, all different types of cells, you will load 4 nibs into the table and import 4 class files? Programmatically set the frame, views, textfields and tag them for later access?
The answer(s) to this is probably subjective, but I'd like to know what you experts consider the most elegant approach to this common problem.
The easiest way to do this is to simply add your controls during the tableView:cellForRowAtIndexPath: method.
I also recommend this to help corral your code:
A technique for using UITableView and retaining your sanity
I would rather set most of the settings that I can in Interface Builder, instead of writing a whole bunch of code to make the visual/layout just right. As you can imagine, it will take quite a few rounds of "modify - build - test" in the iPhone Simulator to get this special table view laid out the way you want it.
I feel it's probably a bit easier to do all of these rough visual changes in IB, then load all of the custom UITableViewCell dynamically via their identifiers in code. You could then do one final round of tweaking on this code, if something that you want is not doable in IB.
Three20 library (extracted from Facebook iPhone app) has a set of ready-made cells that contain various controls.
(Not sure you want to use them, however. Three20 suffers from “not-invented-here” a little bit and tries to subclass and extend everything, so adding it adds quite a bit of a mess to your project. But at least you can use it as an example.)
P.S. Your question inspired me to open a “What are your favourite UITableView / UITableViewCell tricks?” thread on Stack Overflow, check it out for more tips.
