Why is this Button setState not working?

@implementation SLTButton

- (void) setState:(NSInteger)state {

[super setState:state];

int times;

for (times = 0; times = 100; times = times + 1){

if ((state == NSOnState) && ([_ButtonPart2 isTransparent])) {

[_ButtonPart1 setTitle:@"1Blue"];

[_ButtonPart2 setTitle:@""];

}else if ((state == NSOnState)) {

[_ButtonPart1 setTitle:@""];

[_ButtonPart2 setTitle:@"2Blue"];

}else if ((state == NSOffState) && ([_ButtonPart2 isTransparent])) {

[_ButtonPart1 setTitle:@"1Green"];

[_ButtonPart2 setTitle:@""];

}else if ((state == NSOffState)) {

[_ButtonPart1 setTitle:@""];

[_ButtonPart2 setTitle:@"2Green"];

}else if ((state == NSMixedState) &&([_ButtonPart2 isTransparent])){

[_ButtonPart1 setTitle:@"1Yellow"];

[_ButtonPart2 setTitle:@""];

}else if ((state == NSMixedState)) {

[_ButtonPart1 setTitle:@""];

[_ButtonPart2 setTitle:@"2Yellow"];

}

}

}

@end

I made 4 IBOutlet of the buttons and the buttonCell and than i connected them to the 2 separate buttons. so buttonPart1 is one button and buttonPart2 is the other button

but how come this code is not work it wont even set a value to the one that are not transparent. (im going work on the transparent part after this).

here is the project files:

theProject.zip 24kb file

example:

(button) (button)        none clicked

(1Blue)      (     )         part1 clicked but part2 is transparent

(1Green)     (     )         part1 clicked but part2 is still transparent

(1Yellow)    (     )         part1 clicked but part2 is still transparent

than the opposite
