Note: Since the introduction of custom URL schemes, this post has consistently been the top read content on the blog. Although much is the same, there are a few nuances that have changed. This is a re-write of the original post, updated for the latest iOS and Xcode versions. One of the coolest features of the iPhone/iOS SDK is an application’s ability to “bind” itself to a custom URL scheme and for that scheme to be used to launch the application from either a browser or from another application. Registering a Custom URL Scheme The first step is to create a custom URL scheme – start by locating and clicking on the project info.plist in the Xcode Project Navigator. With the plist displayed in the right pane, right click on the list and select Add Row: From the list presented scroll down and select URL types.
Open the directional arrow and you’ll see Item 0, a dictionary entry. Tap on Item 0 and add a new row, select URL Schemes from the drop-down and tap Enter to complete the row insert. 22 Useful Objective-C Snippets for Your iOS Apps. As an iOS developer, I keep a shed-load of Objective-C snippets nearby whenever I’m coding that I often refer to and copy into my apps. There are so many commonly employed elements in an iOS app that it is just about impossible to remember them all.
In this article, I share my favorites, those that I reach for the most. Some are longer than others, but they are all invaluable to any iPhone or iPad developer. One great way to make use of these snippets is to assign them to short keywords in an app like TextExpander, speeding up your app development significantly. Open a URL in Safari [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@" Dial a Number [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@" Dial a Number Launch Mail and Send an Email [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@" Prevent Sleep Mode [UIApplication sharedApplication].idleTimerDisabled = YES;

The UISwitch object is that famous ON/OFF switch that you can use in your in-app settings or in some editing screen. ON/OFF UISwitch allows you to give the user the control to enable/disable functionalities, show/hide objects or even purchase to activate in-app purchases. Follow the directions below and download the source code (link at the bottom of the post) to create your own UISwitch object.
Don’t want to see the whole explanation? Click here and scroll to the full final code.

Segues I think most iOS developers know by now how to create a segue from one View Controller (VC) to another. A segue is the transition between one View Controller and another that occurs when you press a button, or press on a row in a table. It’s easy enough to create one in Interface Builder simply by Ctrl-dragging from the source object to the target View Controller. The options for the segue are “Push”, “Modal” and “Custom”. Push Segue A Push segue is used when you’re using a Navigation Controller. Modal Segue A “Modal” segue creates a relationship between the VC that did the presenting and the VC that was presented. Transitions On an iPhone, there are four types of transitions available: Cover Vertical (default) Used to interrupt the current workflow to gather information from the user.
Flip Horizontal Used to temporarily change the work mode of the app. Cross Dissolve Used to present an alternate interface when the device changes orientations. Custom Segue First View Controller.

Objective-C Objective-C is the primary language used to write Mac software. If you're comfortable with basic object-oriented concepts and the C language, Objective-C will make a lot of sense. If you don't know C, you should read the C Tutorial first. This tutorial is written and illustrated by Scott Stevenson Copyright © 2008 Scott Stevenson Calling Methods To get started as quickly as possible, let's look at some simple examples.
[object method]; [object methodWithInput:input]; Methods can return a value: output = [object methodWithOutput]; output = [object methodWithInputAndOutput:input]; You can call methods on classes too, which is how you create objects. Id myObject = [NSString string]; The id type means that the myObject variable can refer to any kind of object, so the actual class and the methods it implements aren't known when you compile the app. In this example, it's obvious the object type will be an NSString, so we can change the type: NSString* myString = [NSString string]; Accessors.
Xcode Tutorial: How to set the Text of a Label to the Value of an Int (Basic iPhone SDK Development) Adding a UITableView to a custom UIViewController | aboveground.com. On my last tutorial post I demonstrated how one would add a UIToolbar to a UITableViewController for the case where you would want a UITableViewController to be the main view, rather than embedding a UITableView in a custom UIViewController. I will now explain how to do the opposite, which is embedding a UITableView in your own custom view (for showing lists or options, or dynamically updated data).
I will go through creating the UIView, and adding hooks to a UITableView inside our new custom view. In my case, I needed to add a “Recent Searches” table on a custom view that had a search bar. Rather than using the one given by Interface Builder, lets build our own to learn how to do this. First, create a UIViewController by adding a new file.
Lets start off by creating our outlets in the .h file to create our hooks for the search bar and the table view: Dont forget to synthesize the search bar and the table in your class file’s .m: OK, now on to the interface. We now have the basics set up. iOS Quickstart Guide | Firebase Documentation. First, you'll need to sign up to get your own Firebase. Downloading You can grab the latest Firebase.framework by right clicking below and choosing "Save As... ": Download Firebase SDK for Objective-C You can also install the Firebase Xcode project templates to get a fully-configured Firebase project right from Xcode's "New Project" wizard: Xcode Project Templates Alternatively, if you're using CocoaPods, add the following to your Podfile and skip to the "Getting started" section. pod 'Firebase', '~> 1.0.0' Installing Unzip the above file and drag the .framework folder to your XCode project under Frameworks.Firebase depends on these other frameworks.
Getting started Simply include the Firebase header in your app to get all the needed classes: #import <Firebase/Firebase.h> Using the Firebase API to synchronize your data is easy: Firebase* f = [[Firebase alloc] initWithUrl:@" [f setValue:@"Do you have data? Notes For RubyMotion Users To use Firebase with RubyMotion: Undefined symbols for architecture i386 – Reachability - Swift7Media - Today I add the Reachability classes to an app I am working on, added my #import Reachability.h to the correct files and then implemented a method to check if the device was using wifi. When I hit build, I got the following error. I figured it was a framework that I had forgotten to add to I added the CFNetwork.framework and hit build again, same error again. I then added SystemConfiguration.framework into the project and hit build, and success!! It was such a simple fix but the errors that were displayed weren’t really helpful with explaining what framework needed to be added.
