XSLT in a UIWebView using iOS SDK 4.2

阅读更多关于 XSLT in a UIWebView using iOS SDK 4.2

问题 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. 回答1: The answer is yes. Here's an example: NSString *path = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL = [NSURL fileURLWithPath:path]; NSString *xml = @"<?xml version=\"1

阅读更多关于 Generating a PDF using the new printing stuff in iOS 4.2

问题 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]

Archiving project in Xcode incorrectly creates multi-application bundle

阅读更多关于 Archiving project in Xcode incorrectly creates multi-application bundle

Archiving my project in Xcode is creating a multi-application bundle, instead of bundling my main target for release, which is what I want. Specifically, when I validate my archive in Organizer, it gives me the message: "[projectname] does not contain a single–bundle application or contains multiple products. Please select another archive, or adjust your scheme to create a single–bundle application." It sounds like there is some setting in the scheme that needs to be adjusted, but I can't figure out what's causing other targets to be included. I'm using Xcode 4.0 by the way. Jared Friedman OK,
