So I have been trying to get this simple behavior working on my iPhone app now for a while. I have a nav bar at the top and a tab bar at the bottom. I am loading all of my content in a webview, which I want to fit between the two.

How do I make UIWebView show a pdf file from its own app?

阅读更多关于 How do I make UIWebView show a pdf file from its own app?

I really need to make a UIWebView open up a specific PDF document that is in my project directory. I can't seem to find any tutorials on this. I found one, but the author was not specific about some of the code. I have to assume it's got to be quite a simple bit of code. Can someone help me code UIWebView to load a PDF? Thanks. Use pathForResource and fileURLWithPath: NSString *path = [[NSBundle mainBundle] pathForResource:@"FileNameHere" ofType:@"pdf"]; NSURL *url = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [webView loadRequest:request]; 来源：

I was wondering how are apps like McTube ( https://itunes.apple.com/us/app/mctube-for-youtube/id559618284?mt=8 ) playing youtube videos. It looks like a custom MPMoviePlayerController but is that allowed? BTW I need autoplay which I couldn't achieve with UIWebView , that's why i was wondering. Some YouTube videos can be played back in a MPMoviePlayerController - some cannot. When you query a video through the YouTube Data API ( link here ) you'll get back all the content types available for a particular videos, including the Flash player, 3GPP, MP4 ( if available ), etc. You can use these URLs

iPhone UIWebView - How do you set the zoom level and position?

阅读更多关于 iPhone UIWebView - How do you set the zoom level and position?

I'm displaying a series of tiled images in a UIWebView and would like to programmatically set the UIWebview's initial zoom and view location. How does one go about doing so? NOTE: this answer is from 2009. Please see one of the better solutions for a more civilized age. Programmatic scrolling of UIScrollView is now a solved problem. I have a detailed discussion of how (and why) UIScrollView zooming works, an example project and ZoomScrollView class that encapsulates the required zooming magic at github.com/andreyvit/ScrollingMadness/ . So probably you should put your images inside UIScrollView
