The function loadHTMLString from UIWebView costs too much memory and will activate the didReceiveMemoryWarning of the current UIViewController.
How do I solve it please :D
it might be that your html NSString for loadHTMLString: too long, which I mean that the NSString's size for loadHTMLString: is too large. And if you have some image url in your html string, it might have problem,too.
How about storing your HTML in a file and then:
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
NSURLRequest *request = [NSURLRequest requestWithURL:fileURL];
[webView loadRequest:request];
if you use webview only to load one html page
i think you should optimize your page th solve it
if you load many pages you should clean the webview before you load another or dealloc
like this
[webView loadHTMLString: #"" baseURL: nil];

I am using UIWebview to load a weburl, which contains few images and text. But after loading the url on webview images gets replaced with one another on some devices.
Is it problem with webpage?
My Code is here
NSURL *url=[[NSURL alloc]initWithString:_url];
NSURLRequest *request=[NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];
I have attach link to the actual loaded webview.

#image url: http://www.citi.io/wp-content/uploads/2015/10/1291-01-bruges-meteoweb.eu_.jpg
-(NSArray *)imageUrls
{
return [NSArray arrayWithObjects:
[NSURL URLWithString:#"http://imgs.mi9.com/uploads/landscape/4717/free-the-seaside-landscape-of-maldives-wallpaper_422_84903.jpg"],
[NSURL URLWithString:#"http://pics4.city-data.com/cpicc/cfiles42848.jpg"],
nil];
}
Pretty easy enough problem, but It's driving me crazy. I connected my uiwebview to the .h and called it myWebView. then in the viewdidLoad, i did this:
NSString *urlString = #"www.google.com";
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[myWebView loadRequest:request];
But when I run the app I just see a blank screen...
I don't know what's going on.
All help is appreciated, thanks
Your urlstring isn't well-formed (for your intent)
Use http://www.google.com/
Technically www.google.com is a valid URL (according to things like RFC 1738 and 3986), but since it lacks the scheme (the http part), the UIWebView doesn't quite know what to do with it.
I am writing an App where I pass a Link as a NSString from a TableView to my DetailView. The String gets passed correctly, as I can see it in the log. The problem is, that the WebView just stays blank; unless I hard code any URL in. Even the ones that I can see in the log by just copy pasting them. What am I missing? Any help is greatly appreciated. Here's a sample log output and my code. I also checked this thread, where the guy hab the exact same problem as me, but none of the solutions posted there where helpful. UIWebView not loading URL when URL is passed from UITableView

- (void)viewDidLoad
{
[super viewDidLoad];
NSString *urlString = url;
NSURL *myURL = [NSURL URLWithString:urlString];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:myURL];
[webView loadRequest:requestObj];
NSLog(urlString);
}
I think you stringUrl is nil when it loads (so it doesn't get passed. Break point view did load and see the value of the urlstring
Based on what you've said, your url isn't formatted correctly
i think you are missing delegate
self.webView.delegate = self;
Since OS 3.0 UIWebView supports RTF files.
If you have a .rtf file, it's easy enough to load it into a uiwebview, e.g.
NSString *path = [[NSBundle mainBundle] pathForResource:documentName ofType:nil];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
When loading HTML stored in a string variable, you can use loadHTMLString.
How would one load RTF stored in a string directly into a UIWebView? For example, if you have a string containing {\rtf1\ansi\ansicpg1252\cocoartf1038\cocoasubrtf360
{\fonttbl\f0\fswiss\fcharset0 Helvetica;}....., using loadHTMLString will render it literally.
I would like to be able to render RTF from a string variable without having first to save it to a file.
Try loadData:MIMEType:textEncodingName:baseURL:. Haven't tried it, but it's worth a shot.
Hi i want to make a few http request and generate html from within my ipod app. I hear i want a WebView to view the html as if it were a browser. So my question is how do i make the http request? How do i parse json (or xml) and how do i save/load data? I figure i can use webstorage to load/save the data however i am thinking since its an ipod app i have a better way of storing it?
Here's a snippet to load a local html web page contained inside your app bundle:
UIWebView *webView = [[UIWebView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
NSString *path = [[NSBundle mainBundle] pathForResource:#"mywebpage" ofType:#"html"];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:path]]];
Another alternative is to embed a local web server running in a background thread, and use a URL to localhost.
A UIWebview supports HTML5 local storage.
Here is the working code snippet. for iPod/iPhone/iPad;
Works with iOS7 and iOS6.. I have not tested in others...
UIWebView *_webView = [[UIWebView alloc] initWithFrame:self.view.frame];
[self.view addSubview:_webView];
NSURL *url = [NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
