I have made a project and when people put a keyword into UITextfield and click the button then my app will retrieve the data from website database.
It is not working here is the code:
- (IBAction) btnClickMe_Clicked:(id)sender {
NSString *kw = s.text; // <-----THIS IS THE UITextField
NSURL *url = [NSURL URLWithString:#"http://www.example.com/index.php?keyword=",kw];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[iMessageLabel loadRequest:request];
}
Any one could help me?
You aren't putting the keyword into the string. You need something like this:
NSString *kw = s.text;
NSString *encodedkw = [ky stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *urlString = [NSString stringWithFormat: #"http://www.example.com/index.php?keyword=%#", encodedkw];
NSURL *url = [NSURL URLWithString:urlString];
Then look at how to use NSURLConnection to figure out how to put the data into the label.

I have a UIWebView which is adapted to a mobile style of a forum I have. In Safari, it looks and works great.
However, inside my WebView there is a disastrous problem.
When quoting or editing a post, HTML is displayed inside of BBcode. Furthermore, posting code results in ignored line breaks.
The webview is loaded like this:
//display the webview
NSString *fullURL = #"http://www.mysite.com";
NSURL *url = [NSURL URLWithString:fullURL];
NSMutableURLRequest *requestObj = [NSMutableURLRequest requestWithURL:url];
[_webTest loadRequest:requestObj];
Change your this line:
NSMutableURLRequest *requestObj = [NSMutableURLRequest requestWithURL:url];
With this line & check:
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
Do you want to load a html-string in your webView?
If it is the thing than following may help you:
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:bundlePath];
NSString *htmlString = [bundlePath pathForResource:#"index" ofType:#"html"] ;
[webView loadHTMLString:htmlString baseURL:baseURL];
I use this line of code to load a local html file into a web view:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"index" ofType:#"html" inDirectory:#"html"]];
However I want to add some http parameters to the url with no luck so far.
I've tried this:
url = [url URLByAppendingPathComponent:#"?param1=1"];
But after this a html doesn't load in webview.
Is there a way to load local html file in webview with params ?
Do this:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"index" ofType:#"html" inDirectory:#"html"]];
NSString *URLString = [url absoluteString];
NSString *queryString = #"?param1=1";
NSString *URLwithQueryString = [URLString stringByAppendingString: queryString];
NSURL *finalURL = [NSURL URLWithString:URLwithQueryString];
NSURLRequest *request = [NSURLRequest requestWithURL:finalURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:(NSTimeInterval)10.0 ];
[web loadRequest:request];
The most upvoted answer by Prince doesn't always work.
In iOS 7 Apple introduced NSURLComponents class, we can leverage that to securely add a query into NSURL.
NSURL *contentURL = ...;
NSURLComponents *components = [[NSURLComponents alloc] initWithURL:contentURL resolvingAgainstBaseURL:NO];
NSMutableArray *queryItems = [components.queryItems mutableCopy];
if (!queryItems) queryItems = [[NSMutableArray alloc] init];
[queryItems addObject:[NSURLQueryItem queryItemWithName:#"access_token" value:#"token_here"]];
components.queryItems = queryItems;
NSURL *newURL = components.URL;
I use like this way:
NSURL *url=[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"index" ofType:#"xml"]];
If your file included into the Resource folder of project navigator. otherwise you have to set your full path in NSString and use that in your NSURL path.
I am passing url with some string value and NSInteger value in this url but when I put breakpoint on this and I tab on trace then it show me this message exc-bad-access in url I given bold please see that 'bold' I want to pass there value:
[ NSInteger day,NSInteger day1,NSString *fromDate1, NSString *fromDate1,NSString *OriginCode,NSString *DestinCode].
I get all value on url when I put the breakpoint but when I step into breakpoint my app crashes, why it crash? Help me. Where am I wrong?

make your url properly like this:-
NSURL *url = [NSURL URLWithString:[*yourstring* stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
Harish this will help u to in creating the url check this our http://wiki.akosma.com/IPhone_URL_Schemes
like this
NSString *template = #"appigotodo://com.example.xyzapp/import?name=%#¬e=%#&due-date=%#&priority=%#&repeat=%#";
NSString *name = #"Buy%20some%20milk";
NSString *note = #"Stop%20on%20the%20way%20home%20from%20work.";
NSString *dueDate = #"2009-07-16";
NSString *priority = #"1";
NSString *repeat = #"101";
NSString *stringURL = [NSString stringWithFormat:template, name, note, dueDate, priority, repeat];
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
Two things:
The URL has many % symbols that are not being used as placeholders. The % symbols that are not between '**' in your code need to be escaped like so: %%. In other words, SearchInputFRSearchView%24Button should be SearchInputFRSearchView%%24Button.
You are using %i to put integers into your string. You should be using %d instead.
I want to open RSS Feed in my UIWebView, but it isn't working and opening Safari.
My code:
NSString *link = [[NSString alloc] initWithFormat:#"feed://smartfiction.disqus.com/%#/latest.rss", slug];
NSURL *url = [NSURL URLWithString:link];
NSURLRequest *requestWeb = [NSURLRequest requestWithURL:url];
[webViewComment loadRequest:requestWeb];
I found right way. I have created rss parser and showed feed in UITableView. It's more beautiful and easy.
feed:// is a URL Scheme which is handled by Safari and so will only be opened by Safari... you could try :
NSString *link = [[NSString alloc] initWithFormat:#"feed://smartfiction.disqus.com/%#/latest.rss", slug];
NSURL *url = [NSURL URLWithString:link];
NSData *rssData = [NSData dataWithContentsOfURL:url];
[webViewComment loadData:rssData MIMEtype:#"application/rss+xml" textEncodingName:#"utf-8" baseURL:nil];
I have HTML files that I want to load locally. I have included the files in the resources folder in XCode. I am not sure what the syntax is to load them.
This is the code I use to connect to say google.
NSString *urlAddress=#"http\\someurl";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webHelpView loadRequest:requestObj];
Could someone provide an example where a HTML file is loaded locally.
Thanks in advance.
This is the only code that worked for me.
NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"SettingsHelp.html"];
NSURL *url = [NSURL fileURLWithPath:path isDirectory:NO];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
Thanks all for the help.
Can't you just do
NSURL *url = [NSURL URLWithString:#"file:///path/to/file"];
?
Sure, here is some code from an app that loads a locallly stored html page into a web view:
- (void) viewDidLoad
{
// Load the content into the view
NSString* path = [NSString stringWithFormat: #"%#/index.html",
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex: 0]];
[webView_ loadRequest: [NSURLRequest requestWithURL: [NSURL fileURLWithPath: path]]];
}
