Invalid receiver type for NSInteger

Question

• (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"bla %@", [section count]);

  return [possessions count]; }

Does anyone know how to implement a simple NSLog because I am getting an error.

Answer 1

NSLog(@"bla %d", section)

NSInteger is basically just an int (but with marginally better-known characteristics).

Answer 2

Here is the most used format specifiers:

• %d or % D for integer (int)
• %f for float
• %@ for String (in general)

You can see the other format specifiers here :

Answer 3

section is of type NSInteger. NSInteger type declared variables does'nt have function with name count. You can print section value with below code.

NSLog(@"bla %d",section)
