How do I send multiple querystring parameters in ios?

Question

Here is my code

Passing parameters to my Querystring gives me Bad Access Error!

NSString *myJson = @"http://mySite.com/Service.svc/MyList";
myJson = [myJson stringByAppendingFormat:@"?id=%@&uid=%@", firstId, secondId];

Can someone help me out!

What you do here is simple string formatting.

Given what you are doing, I guess firstId & secondId are integers, not objects, so your error is because you don't use the right format.

The format %@ in you stringByAppendingFormat is for displaying an object, or more precisely the string returned by its description selector.

If you want to format an integer, just use %d as in C :)

This will give you :

NSString *myJson = @"http://mySite.com/Service.svc/MyList";
myJson = [myJson stringByAppendingFormat:@"?id=%d&uid=%d", firstId, secondId];
