问题 I want to use a table view as the detail pane in my UISplitViewController. How do I put the toolbar at the top? I want to be able to add bar button items in the same way as my non-table detail views. Thanks. 回答1: My frustration with this problem lay in trying to use the UITableViewController class, which does not allow you to add other UI elements like a toolbar. I solved it by creating a UIViewController object and adding the toolbar and table view to its nib individually. I then had the

问题 I've a problem making div element clickable. I've a HTML5 video on screeen, after video end event I create some div element positioned above video with z-index property. On taping this divs nothing happens, but if this divs are positioned not above video, everything works just fine. Does anybody have workaround for this thing? 回答1: If you disable controls on the video element then it won't steal your click events.

问题 I am writing a GLPaint-esque drawing application for the iPad, however I have hit a stumbling block. Specifically, I am trying to implement two things at the moment: 1) A background image that can be drawn onto. 2) The ability to draw temporary shapes, e.g. you might draw a line, but the final shape would only be committed once the finger has lifted. For the background image, I understand the idea is to draw the image into a VBO and draw it right before every line drawing. This is fine, but

问题 I'm getting memory leaks that i can't figure out through leaks, build/analyze or overall inspection how to repair. I have a very strong notion that it's due to the loadRequest command from my UIWebview loading javascript, but I can't figure out what's wrong. Here's my setup: I have a tabbarcontroller that i programatically create with 4 view controllers: a table view, a mapview, another table view and a webview, respectively. the 1st tableview shows static data. the mapview shows annotations

问题 I need to know each time the user is starting to use the application. Case 1 (OK) : The app is not started. The user starts the application from scratch. I add a listener on the app's bootstrap, and I am aware when it starts. Case 2 (TODO) : The app has been started but it's not active anymore The user reload the application from the taskbar. I want to know when the application comes from the taskbar to the foreground (like a alt+tab). This is tricky to catch, because the app is still running

问题 How can I emulate iPad browser under windows? I know user agent string and I know browser width/height, screen width/height 回答1: I believe if you emulate the User Agent of the iPad and set your windows size appropriately, you can use Safari (windows download from apple.com) and works pretty cool. Also i haven't tested this, but http://code.google.com/p/ibbdemo2/ looks like a great iPad emulator. 回答2: For anybody else still looking, follow these steps for Safari 4+ : Mobile Safari Settings on
