UICatalog |
========== |
This sample is a catalog exhibiting many views and controls in the UIKit framework, along with their various properties and styles. |
If you need code to create specific UI controls or views, refer to this sample and it should give you a good head start in building your user interface. |
In most cases you can simply copy and paste the code snippets you need. |
When images or custom views are used, accessibility code has been added. Using the iPhone Accessibility API enhances the user experience of VoiceOver users. |
Build Requirements |
iOS 4.0 SDK |
Runtime Requirements |
iPhone OS 3.2 or later. |
Using the Sample |
Build and run the sample using iOS 4.0 SDK. |
To run in the simulator, set the Active SDK to Simulator. To run on a device, set the Active SDK to the appropriate Device setting. |
In most areas of this sample, as you see various UI elements, you will see a corresponding explanation as to where you can find the code. |
So for example the Buttons page - the gray button will have "ButtonsViewController.m - createGrayButton". |
This means refer to the ButtonsViewController.m source file and search for the createGrayButton Objective-C method. |
Buttons - This UIViewController or page contains various kinds of UIButton controls complete with background images. |
Controls - This page contains other miscellaneous UIControl classes helpful in building your user interface including switch, slider page, and progress indicator. |
TextFields - This page hosts different kinds of UITextField controls. It also demonstrates how to handle the keyboard, particularly where text fields are placed. |
SearchBar - This pages exhibits the UISearchBar control. |
TextView - This page exhibits the use of UITextView. |
Pickers - This page shows the varying picker style view including UIPickerView and UIDatePicker. UIDatePicker variants include date, time, date & time, as well as a counter. A custom picker is also included in this page. |
Images - Shows how you can create a UIImageView containing a group of images used for animations or slide show. |
Web - Shows how to properly use a UIWebView and target websites using NSURL class. |
Segment - This page adds several types of UISegmentedControl views. |
Toolbar - This page shows how to use UIToolbar and adds several kinds of UIBarButtonItems. |
Alerts - This page shows how to use UIActionSheet and UIAlertView to display varying kinds of alerts that require user actions. This includes simple alerts, OK/Cancel alerts, and alerts with custom titled buttons. |
Transitions - This page shows how to implement view "flipping" and "curl" animations between two different views using a category of UIView called UIViewAnimation. |
Localization - You will notice this sample in various places shows you how to localize your string content by using the NSLocalizedString() macro. Each language has a "Localizeable.strings" file and this macro refers to this file when loading the strings. |
Packaging List |
main.m - Main source file for this sample. |
AppDelegate.h/.m - The application's delegate to setup its window and content. |
