The Exciter - Touches and UIScrollView inside a UITableView Sunday December 28, 2008 UPDATE: please don’t don’t do it like this, it was only needed on iPhoneOS 2.×. A lot have changed in iOS since then and you can now do it properly "Trafikanten" for the iPhone is the iPhone incarnation of the betabrite-style signs hanging around Oslo, providing travellers with real-time departure information on busses, trams and subways. A betabrite sign is basically a set of LED lamps that turn on and off in sequences, usually to portray text scrolling across the screen. The thing is, a UITableView takes completely control of the responder chain (and therefore touches) so that it can try and figure out if the user intents to scroll the scrollview, as described in the documentation overview for the UIScrollView class. Please observe this artist rendition of the view hierarchy: The innermost UIScrollView holds the departure times and it’s the view we want to be able to move horizontally. So that takes care of that right?

Programming The iPhone For Accessibility By The Visually Impaired Per Busch, a blind iPhone user from Germany, has been on a crusade to raise developer awareness about VoiceOver, a new-in-3.0 accessibility enhancement. Per’s is a noble quest, so we’ll do our part here: VoiceOver Over View VoiceOver, says Apple, “describes an application’s user interface and helps users navigate through the application’s views and controls, using speech and sound.” Apple offers a concise document that describes how accessibility is delivered with iPhone 3.0. VoiceOver literally describes what’s on-screen in spoken word. You can label your UI from an inspector panel in Interface Builder. Supporting this level of accessibility isn’t hard. Standard UIKit controls/views support accessibility by default. Limitations, And A Wish-List For Apple Per shared an email conversation with Daniel Ashworth, CEO & Chief Architect of Quokka Studios about the limitations of the VoiceOver.

Color Contrast Calculator This calculator will determine whether two colors you are thinking of using on your slides have enough contrast to be seen clearly by the audience. The calculations are based on international standards developed by the World Wide Web Consortium (W3C) detailed here. There are two tests, a color brightness test and a color difference test. Both tests should be passed in order to ensure that the colors you are using on your slides will be easily seen. How To Use the Calculator In the form below, enter the background color red, green and blue attributes and the text/foreground color red, green and blue attributes. The text/foreground color could also be a color you are considering for lines or shapes on the slide. Suggestions for Improving the Color Brightness Contrast The largest contributor to a difference in color brightness between two colors is the difference in the value for the Green attribute. Suggestions for Improving the Color Difference
iphone应用程序开发指南（读书笔记 2 ） - 今年我们二十五六 - 51CTO技术博客 创建一个新的视图对象时，需要为其分配内存，并向该对象发送一个initWithFrame:消息，以对其进行初始化。举例来说，如果您要创建一个新的UIView 类的实例作为其它视图的容器，则可以使用下面的代码： 在iPhone 程序中，有两个地方最常用于创建视图和子视图， 它们是应用程序委托对象的applicationDidFinishLaunching:方法和视图控制器的loadView 方法。 调用父视图的addSubview:方法来添加视图，该方法将一个视图添加到子视图列表的最后。 调用父视图的insertSubview:...方法可以在父视图的子视图列表中间插入视图。 调用父视图的bringSubviewToFront: 、sendSubviewToBack: 、或 exchangeSubviewAtIndex:withSubviewAtIndex:方法可以对父视图的子视图进行重新排序。 调用子视图（而不是父视图）的removeFromSuperview 方法可以将子视图从父视图中移除。 创建一个带有视图的窗口 - (void)applicationDidFinishLaunching:(UIApplication *)application { // Create the window object and assign it to the // window instance variable of the application delegate. window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; window.backgroundColor = [UIColor whiteColor]; // Create a simple red square CGRect redFrame = CGRectMake(10, 10, 100, 100); UIView *redView = [[UIView alloc] initWithFrame:redFrame]; redView.backgroundColor = [UIColor redColor]; // Create a simple blue square // Add the square views to the window
