when I call
-(IBAction)goback:(id)sender
{
NSURL *xmlURL=[NSURL URLWithString:#"http://demo.komexa.com/sicherungsbereich.xml"];
NSURLRequest *request = [NSURLRequest requestWithURL:xmlURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:2];
NSURLResponse *theResponse;
NSError *theError;
NSData *myRequestResult = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&theError];
NSString *stringReply = (NSString *)[[NSString alloc] initWithData:myRequestResult encoding:NSUTF8StringEncoding];
NSLog(#"reply from server: %#", stringReply);
}
with the Iphone , on the simulator it loads the String everytime really from the internet.But on the devices, it caches the String, so even if the content of http://demo.komexa.com/sicherungsbereich.xml changes (you can do that by calling http://demo.komexa.com) the String does not automatically reload new data.
Have you got an Idea?
I have uploaded the Code here,because of formatting problems:
http://demo.komexa.com/problem.txt
just generate a random number and pass with your url , you get required result
e.g:
int randomNumber1 = 1 + arc4random()% 9;
NSString *rstr = [NSString stringWithFormat: #"%d",randomNumber1];
NSString *address = #"http://www.socialfactory.net/client-app/photovote/get_data.php";
NSString * nstr=[NSString stringWithFormat:#"%#?t=%#",address,rstr];
//NSURLRequest *theRequest=nil;
NSURLRequest * theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:nstr]];
NSURLResponse *resp = nil;
NSError *err = nil;
Maybe your Simulator and iPhone have different proxie settings. check this or try with the NSURLRequestReloadIgnoringLocalAndRemoteCacheData policy which also ignores intermediate cachings. See the docs here.

Alright, so here's where I'm at with my app.
I've got some code that connects to a remote server and grabs some XML data, and forms it into a string. Here is the code below:
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"GET"];
NSString *accept = [NSString stringWithFormat:#"application/xml"];
[request addValue:accept forHTTPHeaderField: #"Accept"];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString* responseString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
NSLog(#"%#",responseString);
Which returns
That's exactly the information I want. My question is how I can get the double value out of the gold brackets and into my application to use.
Thanks a lot!
There are a lot of tutorials of how to use NSXMLParser. For example, ray wenderlich or here and here.
There's quite a few XML parsing options available - ranging from libxml2, to NSXMLParser and a host of open-source projects.
One of my favorite XML parsers is RaptureXML, which can be installed via CocoaPods.
I like to create a category on RXMLElement to parse as follows:
- (PFCurrentConditions*)asCurrentCondition
{
NSString* summary = [[self child:#"weatherDesc"] text];
PFTemperature* temp = [PFTemperature temperatureWithFahrenheitString:[[self child:#"temp_F"] text]];
NSString* humidity = [[self child:#"humidity"] text];
NSString* wind =
[NSString stringWithFormat:#"Wind: %# km %#", [[self child:#"windspeedKmph"] text], [[self child:#"winddir16Point"] text]];
NSString* imageUri = [[self child:#"weatherIconUrl"] text];
return [PFCurrentConditions conditionsWithSummary:summary temperature:temp humidity:humidity wind:wind imageUrl:imageUri];
}
So, you can then use it as follows:
RXMLElement* rootElement = [RXMLElement elementFromXMLData:response.responseData];
__autoreleasing PFWeatherReport* weatherReport = [rootElement asWeatherReport];
Again, this is one of countless options, but my personal favorite.
Api Address：
http://suggest.taobao.com/sug?area=etao&code=utf-8&callback=KISSY.Suggest.callback&q=iphone
return：
KISSY.Suggest.callback({"result": [["iphone4s", "9809"], ["iphone5", "13312"], ["iphone4 手机", "69494400"], ["iphone5 港行", "14267"], ["iphone5三网", "2271160"], ["iphone4手机壳", "6199679"], ["iphone 5手机壳", "2527284"], ["iphone 5 保护壳", "5727586"], ["iphone 4贴膜", "147271"], ["iphone5壳", "2628540"]]})
NSURL * url = [NSURL URLWithString:#"http://suggest.taobao.com/sug?area=etao&code=utf-8&callback=KISSY.Suggest.callback&q=iphone"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSHTTPURLResponse* urlResponse = nil;
NSError * error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSData *date = [NSData alloc]init
SBJsonParser *jsonParser = [[SBJsonParser alloc] init];
// NSMutableArray *array=[NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];
NSMutableArray *array = [jsonParser objectWithData:responseData];
NSLog(#"%#",array);
this array is null. i dont know the reason.
as i refer you request URL ,it has callback in it, if you keep it, it will not return you json as response, so remove "&callback=KISSY.Suggest.callback" from your URL
// Make sure you have include SBJSON files in your Project, as well you have imported header in your View Controller
#import "JSON.h"
// your request URL
NSURL * url = [NSURL URLWithString:#"http://suggest.taobao.com/sug?area=etao&code=utf-8&q=iphone"];
// URL Request
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSHTTPURLResponse* urlResponse = nil;
NSError * error = nil;
// initiate Request to get Data
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
// Encode your Response
NSString *content = [[NSString alloc] initWithBytes:[responseData bytes] length:[responseData length] encoding:NSUTF8StringEncoding];
// Now read a Dictionary from it using SBJSON Parser
NSDictionary *responseDict = [content JSONValue];
NSLog(#"Response [%#]",responseDict);
I'm not familiar with the SBJsonParser, but the format of the returned string looks like JSONP, not JSON. I would imagine simply cleaning out the wrapper call would get you what you are after.
Also, note that the 'root' of your response is a dictionary, not an array.
{"result": [[...
means that the code might should look like this:
NSDictionary *response = //... decode
NSArray *results = [response objectForKey:#"result"];
Edited
You just need to use http://suggest.taobao.com/sug?area=etao&code=utf-8&q=iphone instead of http://suggest.taobao.com/sug?area=etao&code=utf-8&callback=KISSY.Suggest.callback&q=iphone you own code will work..
Hi I would like to know how I can go about sending data from 4 UITextField's to a PHP script on a website using NSURLConnection or JSon. Whatever is easier, how can I do this exactly?
Thanks in advance!
Easiest way (synchronous)
NSString strForTextField1 = textField1.text;
NSString strForTextField2 = textField1.text;
NSString strForTextField3 = textField1.text;
NSString strForTextField4 = textField1.text;
//Build the request
NSString *stringOfRequest = [NSString stringWithFormat:#"www.yourserver.com?var1=%#&var2=%#&var3=%#&var4=%#", strForTextField1, strForTextField2, strForTextField3, strForTextField4];
NSURL *url = [NSURL URLWithString:stringOfRequest];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLResponse *response;
NSError *error;
//send it synchronous
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
if(!error)
{
//log response
NSLog(#"Response from server = %#", responseString);
}
I am developing a text-to-speech iphone app that support multi-languages.
Here is my request URL
requestUrlStr = #"http://www.translate.google.com/translate_tts?tl=en&q=hello";
for english the above url has no problem
but for Chinese
requestUrlStr = #"http://www.translate.google.com/translate_tts?tl=zh-TW&q=你好";
I know the above url will give 'Bad URL', so I used follow method to encode the string into UTF-8
requestUrlStr = [requestUrlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
It will become
http://www.translate.google.com/translate_tts?tl=zh-CN&q=%E4%BD%A0%E5%A5%BD
Then the Google TTS cannot recognize this Chinese text.
You have to pretend to be a User-Agent other than the default (appName, etc) in your NSURLRequest. Try this (I use Greek language) ...
NSString* userAgent = #"Mozilla/5.0";
NSURL *url = [NSURL URLWithString:[#"http://www.translate.google.com/translate_tts?tl=el&q=Καλημέρα"
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest* request = [[[NSMutableURLRequest alloc] initWithURL:url] autorelease];
[request setValue:userAgent forHTTPHeaderField:#"User-Agent"];
NSURLResponse* response = nil;
NSError* error = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
[data writeToFile:#"/var/tmp/tts.mp3" atomically:YES];
UPDATE 2017
Since our favorite companies enjoy to update and deprecate things, here is the above example as it should be now...
NSString* text = #"καλημέρα";
NSString* lang = #"el";
NSString* sUrl = [NSString stringWithFormat:#"https://translate.google.com/translate_tts?q=%#&tl=%#&client=tw-ob", text, lang];
sUrl = [sUrl stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
NSURL* url = [NSURL URLWithString:sUrl];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"GET"];
[request setValue:#"Mozilla/5.0" forHTTPHeaderField:#"User-Agent"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]
delegate:nil
delegateQueue:[NSOperationQueue mainQueue]];
[[session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
[data writeToFile:#"/var/tmp/tts.mp3" atomically:YES];
}
] resume];
The ...delegate:nil delegateQueue:[NSOperationQueue mainQueue] can be omitted.
How can i have a uitextview value be taken and send to a predefined url using obj-c only without any html /php.
Take a look at NSURL. Use the text value of the UITextView as a parameter.
e.g.
NSURL *webURL = [NSURL URLWithString:MY_TEXTVIEW.text];
NSURLRequest *req = [NSURLRequest requestWithURL:webURL];
NSString *methodString = #"method";
NSString *parameterString = [NSString stringWithFormat:#"value=%#", textField.text];
NSString *apiRoot = #"http://www.domain.com";
NSURL *apiUrl = [NSURL URLWithString:[NSString stringWithFormat:#"%#/%#?%#", apiRoot,methodString,parameterString]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:apiUrl];
NSURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
