What will [[UIDevice currentDevice] model] return for "iPad"? 回答1: You can use UI_USER_INTERFACE_IDIOM() , which will either return UIUserInterfaceIdiomPhone or UIUserInterfaceIdiomPad . Bear in mind that on any device < 3.2, this is unavailable, so first check to see whether the property can be retrieved - in

问题 I have view which contains a scrollView. When the view shows up the image appears in full screen (320x480) hiding the status and navigation bar. When I tap the screens - status and navigation bar appears on the screen. But this thing shifts the UIScrollView below the the navigation bar.

Below is how I am positioning the view /

Copy and Paste on iPhone with multiple data representations

由 ♀尐吖头ヾ 提交于 2019-12-09 09:29:06
问题 I encountered some issues when trying to put more than one data representation onto the pasteboard on iPhone 3.0. What I'm trying to do is put a data representation and a string representation onto the pasteboard. The data is my own data type and I use it for copy and paste in my application. The string representation is a way to copy and paste the content of my application as an outline into an other application (for example Mail.app). // payload NSString *pasteboardString = [selectedNode

UITableView and a UITextField that is always visible

由 为君一笑 提交于 2019-12-09 04:26:30
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? Don't use UITableViewController. After all, it's just a standard controller with a full-screen UITableView. You can roll your own easily.

由 无人久伴 提交于 2019-12-09 01:48:57
问题 In my SDK 3.0 core data based app, I have a tab bar controller managing 4 tabs. From time to time, apparently randomly, when I launch the app, it crashes with the following message: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Directly modifying a tab bar managed by a tab bar controller is not allowed.' However, I am not modifying in my code any of the tabs except for the following. In practice, all of the navigation controllers or controllers in the

NSMapTable missing from 3.0 headers?

由 戏子无情 提交于 2019-12-08 13:38:58
问题 I'm using NSMapTable in a program that must run under both 3.0 and 2.2.1. As expected, the program compiles without problems for the 2.2.1 libraries, but when I switch to 3.0, I get compiler errors: error: expected specifier-qualifier-list before 'NSMapTable' In other words, XCode can't find the declaration of the NSMapTable class. I had to put in a forward declaration (@class NSMapTable) in my own header and #import <Foundation/NSMapTable.h> in my implementation file in order to be able to

resignFirstResponder only occurs after processing is complete

由 对着背影说爱祢 提交于 2019-12-08 13:24:17
问题 I want the keyboard to go away as soon as I hit "submit" in my iphone app, and not wait until the function completes. The function takes a long time because I'm doing a synchronous HTTP request. How come the view doesn't update until the whole function completes? I'm working in the simulator in xcode. -(IBAction)submit:(id)sender{ [myTitle resignFirstResponder]; ...some ASIHTTP setup... [request startSynchronous]; return; } 回答1: If you want to keep your current synchronous HTTP request then

How would I drag UITextView around the view screen?

由 陌路散爱 提交于 2019-12-08 13:16:54
问题 I have a project where a UITextView (for multilines) can be dragged around the screen. So far my solution to this has been an overlay of an invisible UIButton which when dragged its center is the same as the UITextView's center. However I've seen apps that seem to just allow the UITextView to be dragged and edited on the fly so it seems there might not be an overlay in those but I'm not sure. Thoughts? By the way, c in this code is the UIButton and this is how I have moved it thus far: -
