问题 I want to integrate the iPhone sms like chat bubbles in my application. But when I read more about it I found that this will not be approved by the app store. Is this true? Cant we use chat bubbles in the application?

问题 I want to create an application which combines a chat feature. My question is this: how can I have a UITextField that is always visible in the same view as a UITableView? The obvious solution would be to create my own UIView having a UITableView and a UITextField below it, however the UITableViewController doesn't seem to like me doing that as it expects the connected "view" outlet to be a UITableView, essentially destroying my plans. Anyone with an idea? 回答1: Don't use UITableViewController.

问题 What is the best way to calculate the distance between two points/Or we can say while we walk calculate distance traveled using accelerometer? My main question is that i'm working on an application in which i need to count distance using two locations but sometimes the core locations fails to update location so at that time how do i calculate the distance traveled? 回答1: You can't even get an accurate measurement of velocity from the accelerometer, so you're definitely not going to be able to

问题 I have some data i want to add in to my app...about 650 categories (includes a name + id number), each with an average of 85 items (each with a name/id number). Will the iPhone support such a large plist? I want to first display the categories in a UITableView, when a category is selected I want to display all of the associated items. Having such a large plist, im not sure if the iPhone will lag when loading the items. At over 51,000 lines it seems like...it might. EDIT: The raw text file is

问题 I'd like to add custom controls to the mediaPlayer control view much as this asker: Add Custom Controls to MoviePlayer However, the solution posted in the above question is depreciated in 3.0. Does anyone know of a way to do this with the new SDK? So far I have added an overlayView to the moviePlayer view and can display my own controls on touch, but I can't seem to pass the touch on to the moviePlayer view to get it to display the native controls. I've been using touchesBegan and

问题 I have a UITableView that gets populated via CoreData , and have just noticed something strange. I have about 20 rows or so in the UITable, and when I scroll down the table and back up again, the cell's label gets written over the top of existing text, and keeps on doing it each time i go down and up again.

问题 I have a tableview which shows a webview on clicking some row in the table, which in turn picks up the data from an sqlite. if a user closes the app by pressing home key while viewing a description in webview and reopens it after sometimes, I should be making the user to see the same screen. how to show the same view again ? What is the efficient way ? 回答1: Well I think the easiest way is to store the state of the application in NSUserDefaults. There is a delegate method on UIApplication
