In a program I was working on, I decided to use Dynamic Type. You can read about it on my blog, but suffice it to say, it is a new way of handling text sizes in iOS7. The user can set a value in their iOS device’s settings to set all text to be bigger or smaller than default, for any app that implements Dynamic Type. This is a bit more advanced than my other posts, but it is surprisingly
When the user taps in a text field, that text field becomes the first responder and automatically asks the system to display the associated keyboard.
When you are dealing with UITextFields one thing you need to handle is the showing and hiding of the keyboard. In this Objective-C Tutorial I will show you how to correctly manage the keyboard for UITextFields.
Firstly, What is an Objective-C Delegate? Well.. An Objective-C delegate is just an object that has been assigned as a delegate of another. There’s no special process for creating them; you simply define a class that implements the delegate methods you’re interested in.
One of the most common jobs mobile apps perform these days is connecting to an online service and displaying its content to users.
A common use case in iOS is creating a form or an editable list of records directly inside a UITableView. We could send the user to a separate “detail” view controller for editing, but that complicates and slows down the user experience.
Another great addition to our iOS Tutorials set. This Beginners guide to objective-c tutorial series is intended for iOS developers who already know object oriented programming and covers all the concepts in Objective-C that you need to understand in order to use the language and learn programming for iOS and OS X.
BSON is often referred as Binary JSON. BSON is the serialization of JSON-like objects that are binary encoded. Just like JSON, BSON also supports nested objects, arrays, strings, integers etc. BSON supports some more data types, especially raw binary data. So we can consider BSON as a super-set of JSON. BSON is designed to be fast to transport and fast to decode. The main features of BSON are: Traversable Light weight and Efficient Lets stop lecturing about BSON and move on to discussion regarding
I know the title is a mouthful, but this tutorial is going to be chock-full-of information on how to make a URL request with ASIHTTPRequest (ASI for short) you’ll see how simple ASI makes it to make a URL Request on iOS. We’re going to download some JSON from COLOURlovers and then parse it with SBJson. Finally, I’m going to show you a few methods for caching our data for offline storage. I personally include these two frameworks in all
