How to assign a value to a BOOL pointer in Objective-C?

Question

I'm having a bit of a confusion on how to assign a value to a BOOL pointer? Here's my code:

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {     self.latitude.text = [NSString stringWithFormat:@"%f", newLocation.coordinate.latitude];     self.longitude.text = [NSString stringWithFormat:@"%f", newLocation.coordinate.longitude];      if (!initialBroadcast) {         initialBroadcast = YES; // Where I'm having troubles          [broadcastTimer fire];     }; } 

The compiler keeps telling me this: Incompatible integer to pointer conversion assigning to 'BOOL *' (aka 'signed char *') from 'BOOL' (aka 'signed char').

I'd appreciate a clarification on this since I am a nubski.

UPDATE

As many of you have pointed out, I am apparently abusing the declaration of a BOOL by using a pointer for it. To be honest, I don't know why I used it, but since I'm new to Objective-C it must have worked for what I was doing so it stuck.

Anyway, I have since changed the declaration to:

//  In .h @interface ... {     BOOL initialBroadcast; }  @property BOOL initialBroadcast;  //  In .m @synthesize initialBroadcast; 

So, am I on the right track now?

Answer 1

You need to say

*initialBroadcast = YES; 

initialBroadcast is a pointer aka memory address. The * gives access to the value at the memory address that the pointer holds. So initialBroadcast is a memory address, but *initialBroadcast is a boolean or char.
