I need to do this GET request:

http://api.testmy.co.il/api/sync?BID=1049&ClientCode=3847&Discount=2.34&Service=0&Items=[{"Name":"Tax","Price":"2.11","Quantity":"1","SerialID":"1","Remarks":"","Toppings":""}]&Payments=[]

In browser I get response:

{
  "Success":true,
  "Atava":[],
  "Pending":[], 
  "CallWaiter":false
}

But in iOS it not work.

i try:

NSString *requestedURL=[NSString stringWithFormat:@"http://api.testmy.co.il/api/sync?BID=%i&ClientCode=%i&Discount=2.34&Service=0&Items=[{\"Name\":\"Tax\",\"Price\":\"2.11\",\"Quantity\":\"1\",\"SerialID\":\"1\",\"Remarks\":\"\",\"Toppings\":\"\"}]&Payments=[]",BID,num];
NSURL *url = [NSURL URLWithString:requestedURL];
NSURLResponse *response;
NSData *GETReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSString *theReply = [[NSString alloc] initWithBytes:[GETReply bytes] length:[GETReply length] encoding: NSASCIIStringEncoding];
NSLog(@"Reply: %@", theReply);

OR

NSString *requestedURL=[NSString stringWithFormat:@"http://api.testmy.co.il/api/sync?BID=%i&ClientCode=%i&Discount=2.34&Service=0&Items=[{'Name':'Tax','Price':'2.11','Quantity':'1','SerialID':'1','Remarks':'','Toppings':''}]&Payments=[]",BID,num];

OR

NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
[params setObject:@"Tax" forKey:@"Name"];
[params setObject:@"2.11" forKey:@"Price"];
[params setObject:@"1" forKey:@"Quantity"];
[params setObject:@"1" forKey:@"SerialID"];
[params setObject:@"" forKey:@"Remarks"];
[params setObject:@"" forKey:@"Toppings"];

NSData *jsonData = nil;
NSString *jsonString = nil;

if([NSJSONSerialization isValidJSONObject:params])
{
    jsonData = [NSJSONSerialization dataWithJSONObject:params options:0 error:nil];
    jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding];
    NSLog(@"%@",jsonString);
}

NSString *get=[NSString stringWithFormat:
                @"&Items=%@",
                jsonString];


NSData *getData = [get dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"GET"];
[request setTimeoutInterval:8];
[request setHTTPBody:getData];
[request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"Content-Type"];

nothing doesn't work. How to fix it? Sorry for bad english.
