警告：格式不是字符串文字，也没有格式参数

Question

When i run the below code

NSLog([NSString stringWithFormat:@"Response count is %d",response.products.count]);

i get a warning message like below

warning: format not a string literal and no format arguments

what is the problem in my syntax..

Answer 1

You don't need to create another autoreleased string, just pass it straight to NSLog :

NSLog(@"Response count is %d",response.products.count);

The reason why this warning is popping up is because you didn't supply a format string as the first argument to NSLog .
