calling method webService (WCF) from iOS objective C) - ios

Question

I want calling method webService by parameter Json from IOS, but I received an error.
Code Server Side (WCF):
[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "/test/{input}")]
int test(string input);
I want get input (parameter method and url) = typeof (Json)
Code Client Side (iOS-objective C) :
NSString *json = [self convertToJson:myObject];
NSString *urlComplete = [NSString stringWithFormat:#"%#%#",#"http://test.com/Service.svc/test/",json];
urlComplete = [urlComplete stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setURL:[NSURL URLWithString:urlComplete]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:
^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if (data.length > 0 && connectionError == nil) {
NSString *string = [[NSString alloc]initWithData:data encoding:NSASCIIStringEncoding];
NSLog(#"Data Recived:\n %#",string);
}
else{
NSLog(#"Error %#",[connectionError description]);
}
}];
The webService is being tested by windowsPhone and returns OK but doesn't work with iOS.
Please help me!
thanks:)

Error description "HTTP Error 400. The request URL is invalid." clears that url you are passing is incorrect. Please cross check with windows team if they are appending the JSON to the get URL.
Generally, if you want to post data you can set the requestdata which is JSON and go for either a PUT or POST request instead of GET request.
