In my webview viewdidload i'm implementing the following code. the problem is the webview won't appear when I include the NSString *encodedString. I have searchString with spaces and sometimes &. Any ideas on what's going on here?
NSString *urlString = [NSString stringWithFormat:#"http://google.com?q=%#", searchString];
NSString * encodedString = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(
NULL,(CFStringRef)urlString,
NULL,(CFStringRef)#"!*'();:#&=+$,/?%#[]",
kCFStringEncodingUTF8 ));
NSLog(#"searchString is %#", searchString);
NSURL *myURL =[NSURL URLWithString:encodedString];
NSURLRequest *myRequest = [NSURLRequest requestWithURL:myURL];
[searchWebView loadRequest:myRequest];
What would it take to generate the first page results of google for this searchString?
Try This
NSString *urlString = [NSString stringWithFormat:#"http://www.google.com/search?q=%#",searchString];
urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *myURL =[NSURL URLWithString:urlString];
NSURLRequest *myRequest = [NSURLRequest requestWithURL:myURL];
[searchWebView loadRequest:myRequest];
Use this to encode Your SearchString
SearchString=[[NSString stringWithFormat:#"%#", SearchString] stringByAddingPercentEncodingWithAllowedCharacters:NSCharacterSet.URLQueryAllowedCharacterSet];
and then append it to your URL

I am trying to give my simple browser the ability to recognize that text with spaces should be treated as a google search query. To create a string that can go into a url I need to replace the spaces with "+"s.
I have attempted to do this in the first "if" statement however when I do run the program and put text with spaces into the search bar nothing happens; entering "google.com" or other urls work though.
What is wrong with my code?
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
NSString *URLString = textField.text;
NSURL *URL = [NSURL URLWithString:URLString];
if ([URLString rangeOfString:#" "].location != NSNotFound) {
NSString *plusReplace = [URLString stringByReplacingOccurrencesOfString:#" " withString:#"+"];
URL = [NSURL URLWithString:[NSString stringWithFormat:#"google.com/search?q=<%# query", plusReplace]];
}
if (!URL.scheme) {
// The user didn't type http: or https:
URL = [NSURL URLWithString:[NSString stringWithFormat:#"http://%#", URLString]];
}
if (URL) {
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
[self.webView loadRequest:request];
}
return NO;
}
I think you might have an issue with the 3rd conditional making a 2nd request. What if you change it to this?
if (URL) {
NSString *plusReplace = [URLString stringByReplacingOccurrencesOfString:#" " withString:#"+"];
URL = [NSURL URLWithString:[NSString stringWithFormat:#"google.com/search?q=<%# query", plusReplace]];
}
if (!URL.scheme) {
// The user didn't type http: or https:
URL = [NSURL URLWithString:[NSString stringWithFormat:#"http://%#", URLString]];
}
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
[self.webView loadRequest:request];
i am NewBie in iOS Development. I want to Decode my NSURL With Pagination Here my Url Like as

NSString *urlString = #"http://www.janvajevu.com/webservice/categorylist.php?category=%E0%AA%B8%E0%AB%8D%E0%AA%B5%E0%AA%BE%E0%AA%B8%E0%AB%8D%E0%AA%A5%E0%AA%AF&page=";
NSURL *targetURL = [NSURL URLWithString:[NSString stringWithFormat:#"%#%d",urlString,pageNumber]];
NSLog(#"targetURL is : %#",targetURL);
Hope this will help you..
NSString *str=#"http://www.janvajevu.com/webservice/categorylist.php?category=%E0%AA%B8%E0%AB%8D%E0%AA%B5%E0%AA%BE%E0%AA%B8%E0%AB%8D%E0%AA%A5%E0%AA%AF&page=0";
NSString *result =[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *urls = [NSURL URLWithString:result] ;
Stucked on load the below Local path url in UIWebview. Find the url in spinepath, then i converted to url [SpinePathUrl].
My issue is, when i try to load,i'm getting nil value.
For checking purpose, i pasted the SpinepathUrl into browser it show webpage not found.Then, i changed SpinePathUrl "arugoswami-4.xhtml%23toc_marker-4" into "arugoswami-4.xhtml#toc_marker-4", its showed result.
Is the # is my issue in url.? Why the # converted to %23, when it converting from String to Url.
spinepath = [NSString stringWithFormat:#"%#%#",documentsDirectory,Path];
spinepath = [spinepath stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
spinepath = [spinepath stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSURL *SpinePathUrl = [NSURL fileURLWithPath:spinepath];

NSURLRequest *request = [NSURLRequest requestWithURL:SpinePathUrl];
[webView loadRequest:request];
Try adding fragment manually
NSURL *baseUrl = [NSURL fileURLWithPath:#"... arugoswami-4.xhtml"];
NSURL *fullURL = [NSURL URLWithString:#"#toc_marker-4" relativeToURL:baseUrl];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:fullURL];
[myWebView loadRequest:urlRequest];
I have to parse the return of a JSON API for which I've taken the URL into a string and after that I passed it NSURL but in NSLog it is showing nil.
Here is my code,
NSString *urlstring=[NSString stringWithFormat:#"http://api.v3.factual.com/t/places?q=%#&geo={\"$circle\":{\"$center\":[19.9909631,73.8034808],\"$meters\":40000}}&limit=20&KEY=123456",[self.strurl lowercaseString]];
NSURL *url=[[NSURL alloc]initWithString:urlstring ];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
Thanks in advance.
You must encode your url as it contains special characters, Try something like this
NSString *paramString=[NSString stringWithFormat:#"/t/places?q=%#&geo={\"$circle\":{\"$center\":[19.9909631,73.8034808],\"$meters\":40000}}&limit=20&KEY=123456",[self.strurl lowercaseString]];
NSString *encodedSearchString = [paramString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *urlString = [NSString stringWithFormat:#"http://api.v3.factual.com%#", encodedSearchString];
NSURL *url = [NSURL URLWithString:urlString];
NSLog(#"urlstring is %#",url)
Hope this helps
Try this, Tested and Working
-(void) sample
{
// NSString *strurl = #"hello";
NSString *urlstring=[NSString stringWithFormat:#"http://api.v3.factual.com/t/places?q=%#&geo={\"$circle\":{\"$center\":[19.9909631,73.8034808],\"$meters\":40000}}&limit=20&KEY=123456",[strurl lowercaseString]];
NSURL *url=[NSURL URLWithString:[urlstring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
NSLog(#"%#",req);
}
I have a link of a website, and I want to get its title.
I tried to do by this code
UIWebView* hiddenWebView;
NSString* urlString = #"http://www.youtube.com/watch?v=OyORxdjGtlk";
NSURL* url = [NSURL URLWithString:urlString];
NSURLRequest* request = [NSURLRequest requestWithURL:url];
[hiddenWebView loadRequest:request];
NSString* text = [hiddenWebView stringByEvaluatingJavaScriptFromString:#"document.title"];
But the result is: text = NULL;
I just want to get the name of the video
Set the UIWebView delegate to your ViewController (for example by ctrl-dragging in Interface Builder) and then:
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
NSURL *url = [webView.request mainDocumentURL];
NSString *str = [url absoluteString];
NSString *title = [webView stringByEvaluatingJavaScriptFromString:#"document.title"];
NSLog(#"%s: url=%# str=%# title=%#", __PRETTY_FUNCTION__, url, str, title);
}
