So normally to load a UIWebView I do..
NSURL *url = [NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
However, now I need to do this dynamically, depending on a table cell that a user clicks. I load the table cells from JSON and everything works fine. Now I need to get the "id" of the post in the cell, and load it dynamically. Currently I've tried this but it doesn't work...
NSURL *url = [NSURL URLWithString:#"http://www.google.com/story.php?id="];
url = [NSURL URLWithString:storyId relativeToURL:url];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
Any tips?
Why don't you just format the URL string?
NSURL *url = [NSURL URLWithString:[NSString
stringWithFormat:#"http://www.google.com/story.php?id=%#", storyId]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];

In my app I sent a request to my PHP file to download some info. Whenever I use the code below it will terminate:
-(void)downloadItems
{
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *myString = [prefs stringForKey:#"commentsId"];
NSLog(#"The comments id is : %#",myString);
// Download the json file
NSString *urlstring = [NSString stringWithFormat:#"http:/MyWebSite.com/checkphp.php?title=%#", myString];
NSURL *jsonFileUrl = [NSURL URLWithString:urlstring];
NSLog(#"The qasida id is: %#", jsonFileUrl);
// Create the request
NSURLRequest *urlRequest = [[NSURLRequest alloc] initWithURL:jsonFileUrl];
// Create the NSURLConnection
[NSURLConnection connectionWithRequest:urlRequest delegate:self];
}
But if I remove myString from urlString like this:
NSURL *jsonFileUrl = [NSURL URLWithString:#"http:/myWebSite/checkphp.php?title=%#"];
the app will not terminate and it will retrieve data.
Can any one tell me what is wrong with my code?
Thanks

Try this,
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathExtension:#"sample.pdf"];
NSURL *url = [NSURL fileURLWithPath:filePath];
NSString *urlString = [url absoluteString];
NSString *encodedString=[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *webURL = [NSURL URLWithString:encodedString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];
I am attempting to integrate the Facebook API in my iOS app, but am getting the following error:
WebKit discarded an uncaught exception in the
webView:decidePolicyForNavigationAction:request:frame:decisionListener:
delegate: Application tried to present
modally an active controller .
How can I solve this error?
Here is my code:
[_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"about:blank"]]];
NSString *redirectUrlString = #"http://www.facebook.com/connect/login_success.html";
NSString *authFormatString = #"https://graph.facebook.com/oauth/authorize?client_id=%#&redirect_uri=%#&scope=%#&type=user_agent&display=touch";
NSString *urlString = [NSString stringWithFormat:authFormatString, _apiKey, redirectUrlString, _requestedPermissions];
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
For checking the login credential, i am writing the below code inside the function logincheck
if ([urlString rangeOfString:#"login.php"].location != NSNotFound)

[_delegate displayRequired];
}
I have just re-designed my iPhone app using Storyboard... questin is: how do I address the the UIWebView so I can load the html? (I am a newbie when it comes to Obj-C, having done my previous app in MonoTouch, so I'm kinda lost). :D
- (void)viewDidLoad {
NSString *urlAddress = #”http://www.stackoverflow.com”;
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
}
Apple Developer docs are really good resource. The usage of UIWebView is outlined here enter link description here
To load a network resource simply pass a NSURLRequest object to loadRequest.
[self.myWebView loadRequest:[NSURLRequest
requestWithURL:[NSURL URLWithString:#"http://www.apple.com/"]]];
You can also do this in viewDidLoad (a UIWebView is a subclass of UIView and inherits all its methods). For example, loading a local pdf resource.
- (void)viewDidLoad {
[super viewDidLoad];
NSString *thePath = [[NSBundle mainBundle] pathForResource:#"iPhone_User_Guide" ofType:#"pdf"];
if (thePath) {
NSData *pdfData = [NSData dataWithContentsOfFile:thePath];
[(UIWebView *)self.view loadData:pdfData MIMEType:#"application/pdf"
textEncodingName:#"utf-8" baseURL:nil];
}
}
To setup your UIWebView with a link, just use the following code.
var URLPath = "Insert email address here"
Then use...
loadAddressURL()
and finally...
func loadAddressURL(){
let requestURL = NSURL(string:URLPath)
let request = NSURLRequest(URL: requestURL!)
Webview.loadRequest(request)
}

NSString *urlString = [NSString stringWithFormat:#"http://www.mywebsite.com/login.php?email=username#yahoo.com&pwd=pass"];
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection release];
[request release];
