On iOS, why the init in ViewController didn't work?

In the ViewController's interface, I have

@property int count;
 

and in the implementation, I have

@synthesize count;
 
 -(id) init {
     self = [super init];
     if (self) {
         self.count = 100;
     }
     return self;
 }
 
 -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
     NSLog(@"%i", self.count++);
 }
 

but for some reason, the first time self.count got printed, it is 0 but not 100?
