How to detect redirect in a UIWebView

阅读更多关于 How to detect redirect in a UIWebView

I am using a UIWebView as an embedded browser within my app. The problem I have is tracking the URL that should be displayed in the URL bar. When doing a Google search, the results page often generates links like this: http://www.google.com/url?sa=t&source=web&cd=1&ved=0CC4QFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FDog&rct=j&q=dogs&ei=27XeTc6RFIWEvAO858DHBQ&usg=AFQjCNGkEDcWzea4pSlurHhcuQfqFcp_pw When the user clicks this link, the UIWebView first reports this link and then the redirected link in shouldStartLoadWithRequest:navigationType: . How can I tell this is a redirect as opposed to

Get HTTP Response header on UIWebView

阅读更多关于 Get HTTP Response header on UIWebView

How can I get HTTP headers response from WebView? I've found semi-solutions at Stackoverflow , but it's written on Objective-C and can't convert it to Swift (I've tried with my poor Obj-C knowledge). Objective-C code: - (void)webViewDidFinishLoad:(UIWebView *)webView { NSCachedURLResponse *resp = [[NSURLCache sharedURLCache] cachedResponseForRequest:webView.request]; NSLog(@"%@",[(NSHTTPURLResponse*)resp.response allHeaderFields]); } How that code will look at Swift? Maybe now we have better ways to do so? Caching is not always enabled. Swift Swift is more stringent ; you want to protect

I have a script in my app that loads a Youtube link in a section of the UIView, the link is provided by my server (mySQL/using php) and from that it is loaded... this script below works fine..... however... Here is what I have right now, I was looking to remove the programmatically part (where it gives the dimensions and possibly replace it with a UIWebView) to it, so I could improvise using IB, this will help when my application launches, a quick animation occurs and then I want this youtube link to load and display after viewDidLoad is completed. .h file: - (void)embedYouTube:(NSString *

阅读更多关于 Injecting CSS into UIWebView using JavaScript

问题 I am attempting to inject a local CSS file to override the styling of a webpage. The webpage is presented in a UIWebView container in iOS. However I am not able to get my code to work. See the snippet of my delegate method below. This code runs (I can see the NSLog message) but I do not see the results of it's execution on the page. I know it can't be the CSS I wrote because in this case I took the pages own CSS file and simply changed some colors. (In order to test this method) -(void

How to preselect contenteditable field in UIWebView iOS5

阅读更多关于 How to preselect contenteditable field in UIWebView iOS5

First of all I know contenteditable is only iOS 5 I have accounted for this - we are giving users with iOS 5 a feature to allow Rich Text pasting using contenteditable. This feature works great so far all I want to do is when the view appears to set the contenteditable field as active (pre-select it) so that the keyboard appears and the user can begin typing right-away. Here is the local html file I am using for the UIWebView <html> <body> <div id="content" contenteditable="true" style="font-family: Helvetica">PLACEHOLDER</div> </body> </html> I have already tried using some javascript to

How to embed local images in UIWebView?

阅读更多关于 How to embed local images in UIWebView?

Is there an easy way to embed local images in an UIWebView? For example, I would want to embed an logo.png image in the UIWebView, which I've added to the Resources folder in Xcode. Would I simply add an img HTML tag for this? yes it's very simple but, for others, remember to put "file://" at the beginning of your path for example: NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"png"]; [myWebView loadHTMLString:[NSString stringWithFormat:@"<html><body><img src=\"file://%@\"></body></html>",path] baseURL:nil]; 来源： https://stackoverflow.com/questions/3808451/how-to-embed

XSLT in a UIWebView using iOS SDK 4.2

阅读更多关于 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

Opening a new UIViewController when a link on a UIWebView is clicked

阅读更多关于 Opening a new UIViewController when a link on a UIWebView is clicked

问题 I found this thread which matches my problem: Clicking a link in UIWebView pushes onto the NavigationView stack However, the following situations are different: Instead of using a navigationController, I am using a View Based application to manually switch to different viewcontroller when corresponding buttons are pressed. Rather than using links I am using onClick method to detect when a user clicks on something on a UIWebView and trying to open a new ViewController with a new UIWebView.
