I am trying to implement a 3D Carousel on the iPad, consisting of UIViews, an effect like what is shown over here . I have gone through many similar questions on SO, but didn't find any staisfactory answers or no answers at all. I am trying to achieve the effect through modifying the coverflow animation but it just doesn't give that slick effect. Has anyone implemented this?(open for suggestions through quartz and openGL both) No need to dive into Quartz or OpenGL, assuming you don't mind foregoing the blur. The page you link to gets the perspective wrong (that's why the images in the

问题 I am trying to build and run the WhereamI.app example of the Big Nerd Ranch book: iOS Programming, chapter4. Compiling works just fine and it runs but the output to console is: server did not accept client registration 68, instead of providing the current GPS position and altitude. I am runing Xcode 4.1 on OS X Lion with the 4.3 SDK. There is nothing fancy at all in the code. JUst and instance of Corelocation manager and a simple delegation to WhereAmI.app Any clues? 回答1: I had the same

Issue with Map Annotation and MKMapView in iOS 4.2?

守給你的承諾、 提交于 2019-11-29 15:17:09
I have a map view with pins that when the user selects a pin it goes to a detail screen for that pin. I also have a table view that when the user selects an item it goes to the same type detail view. Here's the problem ... It seems to work fine in everything from 3.1.3 to 4.1. That is the detail view matches with the pin. But I have a user who just upgraded to iOS 4.2 and says that under 4.1 it worked fine, but in 4.2 the pin selection takes him to the detail for a different pin. But in the table view it still works fine. Is it possible that there was a change in MKMapView in iOS 4.2 that

Access BPM field on a song (MPMediaItemPropertyBeatsPerMinute not working)

问题 I'm building an application that has a media player in it (I'm using iOS SDK 4.2). While a given song is playing, I can access pretty much every one of the properties, but I can not access MPMediaItemPropertyBeatsPerMinute. It returns null every time. The Apple doc states: The number of musical beats per minute for the media item, corresponding to the “BPM” field in the Info tab in the Get Info dialog in iTunes. Value is an NSNumber object representing an NSUInteger data type. Available in

XSLT in a UIWebView using iOS SDK 4.2

Is it possible to use XSLT in a UIWebView using iOS SDK 4.2? Alternatively, is it possible to use XSLT in iOS SDK 4.2 outside of a UIWebView? I have seen similar questions to this, but they seem to be dated and refer to pre-4.0 iOS SDKs. If it is possible, a link to a simple iOS XSLT example would be great too. TIA. The answer is yes. Here's an example: NSString *path = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL = [NSURL fileURLWithPath:path]; NSString *xml = @"<?xml version=\"1.0\"?><?xml-stylesheet type=\"text/xsl\" href=\"greeting.xsl\"?><greeting>Hello, World!</greeting>"; [self

Forcing an iPad app to show splitView even in Portrait orientation(Like the Settings iPad app)

大城市里の小女人 提交于 2019-11-29 02:42:16
I am trying to develop a splitView based iPad app, that displays the split interface in every orientation. I have tried subclassing the UISplitViewController class as given in this tutorial, but it doesn't work. I tried creating a category to set _hidesMasterViewInPortrait = (hidden) ? 0 : 1; , as suggested in one of the comments in the above blog, but nothing worked. Can anyone help me to find a way out of this, without using any third party frameworks or classes? I never achieved to force the SPlitViewController to do that but since you need to create controllers for both parts, you can just

Generating a PDF using the new printing stuff in iOS 4.2

删除回忆录丶 提交于 2019-11-28 17:40:32
Historically, my app has generated confirmations as plain HTML and passed that HTML to the normal MFMailComposeViewController for emailing to the customer. I wanted to try to leverage the new printing classes in iOS 4.2 to render the HTML to a PDF instead and send that as an attachment. I tried the following: NSString *html = /* generate my HTML here */ NSMutableData *pdfData = [NSMutableData data]; UIMarkupTextPrintFormatter *fmt = [[UIMarkupTextPrintFormatter alloc] initWithMarkupText:html]; // Render the html into a PDF UIGraphicsBeginPDFContextToData( pdfData, CGRectZero, nil ); for

How to check if location services are enabled for a particular app prior to iOS 4.2?

问题 How can I check if the user has allowed location for mu app? Normally I would use authorizationStatus method of the CLLocationManager class, but it is only available in iOS 4.2 and newer. Is it possible to achieve this somehow while still using SDK 4.2, so that the app can still run on devices with older versions of iOS, or do I have to downgrade the SDK? And along the same line, I need a similar alternative for the locationServicesEnabled method prior to iOS 4.0. 回答1: When you call

How to print in iOS 4.2?

I want to integrate the print functionality in my app. The document I want to print will be in .doc or .txt format. I am not very experienced in iPhone development yet, so finding it difficult to implement it by following the Apple documentation. If someone could help me by posting some sample code, will be a great help. Check out the Drawing and Printing Guide for iOS -- I linked to the printing section. There's sample code and good links to more sample code there. Edit : I see now that you indicate you find the documentation difficult to follow. Word documents are complicated -- you'll need
