I am trying to use a boolean in my code to determine if a state has been reached and if I step through the code it appears that it is trying to set the boolean to the correct value but is not setting the correct value. I had some difficulties with setting an int value to an NSNumber value and visa versa but I resolved them by looking at some open source code. Apple's documentation on NSNumber seems to be incomplete. What is the proper way to set a NSNumber that is inited as a bool? Here is my code. The first two statements work but not the third.

NSNumber *uniqueName = [[NSNumber alloc] initWithBool:TRUE];
//1
uniqueName = FALSE;
//2
uniqueName = [NSNumber numberWithBool:FALSE];
//3
uniqueName = [comparisionGroupName isEqualToString:[[groupArray objectAtIndex:0] objectAtIndex:i]];

I have tried [comparisionGroupName isEqualToString:@"string"]; and it still doesn't return that the string is equal.

The other question that I have is that when I call the third line I get a warning during build "assignment makes pointer from integer without a cast" and when I check to see if a boolean is equal using "if (uniqueName == FALSE) " I get the warning "comparision between pointer and integer" Should I be using "if (uniqueName)" or "if (!uniqueName)" instead?

A BOOL is a C scalar type, and NSNumber is an object. You can't use objects directly with the C ==, !=, <, >, etc. operators; you need the scalar values.

Also, YES and NO are the values typically used for BOOL, not TRUE and FALSE, though either should work really.

BOOL value = NO;
BOOL value2 = [name isEqualToString:[groupArray objectAtIndex:0]];
NSNumber *boolNumber = [NSNumber numberWithBool:YES];
NSNumber *boolNumber2 = [NSNumber numberWithBool:value2];

if (value2 == [boolNumber boolValue])
{
...
}

if (![boolNumber2 boolValue])
{
...
}

if (value)
{
...
}
