UIButton @selector не вызывая метод при нажатии

Question

Вот мой код:

- (void)loadView { 

    //hard coded array of content for each site 

    // CC 
    NSMutableArray *allccContent = [[NSMutableArray alloc] init]; 

    NSString *cc1 = @"House Model"; 
    NSString *cc2 = @"James Dexter History"; 

    [allccContent addObject: cc1]; 
    [cc1 release]; 

    [allccContent addObject: cc2]; 
    [cc2 release]; 

    // FC 
    NSMutableArray *allfcContent = [[NSMutableArray alloc] init]; 

    NSString *fc1 = @"Ghost House"; 
    NSString *fc2 = @"Franklins Letters"; 
    NSString *fc3 = @"Franklins Business"; 

    [allfcContent addObject: fc1]; 
    [fc1 release]; 

    [allfcContent addObject: fc2]; 
    [fc2 release]; 

    [allfcContent addObject: fc3]; 
    [fc3 release]; 

    // PC 
    NSMutableArray *allphContent = [[NSMutableArray alloc] init]; 

    NSString *ph1 = @"Changing Occupancy"; 
    NSString *ph2 = @"Sketches"; 
    NSString *ph3 = @"Servant House"; 
    NSString *ph4 = @"Monument"; 
    NSString *ph5 = @"Virtual Model"; 

    [allphContent addObject: ph1]; 
    [ph1 release]; 

    [allphContent addObject: ph2]; 
    [ph2 release]; 

    [allphContent addObject: ph3]; 
    [ph3 release]; 

    [allphContent addObject: ph4]; 
    [ph4 release]; 

    [allphContent addObject: ph5]; 
    [ph5 release]; 

    // Each content page's view 

    //UIView *ccContent = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 
    UIView *fcContent = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 
    UIView *phContent = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 

    //ccContent.backgroundColor = [UIColor whiteColor]; 
    fcContent.backgroundColor = [UIColor whiteColor]; 
    phContent.backgroundColor = [UIColor whiteColor]; 

    //[ccContent addSubview:[SiteOneController myNavBar1:@"Constitution Center Content"]]; 
    [fcContent addSubview:[SiteOneController myNavBar1:@"Franklin Court Content"]]; 
    [phContent addSubview:[SiteOneController myNavBar1:@"Presidents House Content"]]; 

    //allocate the view 
    self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 

    //set the view's background color 
    self.view.backgroundColor = [UIColor whiteColor]; 

    [self.view addSubview:[SiteOneController myNavBar1:@"Sites"]]; 

    NSMutableArray *sites = [[NSMutableArray alloc] init]; 

    NSString *one = @"Constution Center"; 
    NSString *two = @"Franklin Court"; 
    NSString *three = @"Presidents House"; 

    [sites addObject: one]; 
    [one release]; 

    [sites addObject: two]; 
    [two release]; 

    [sites addObject: three]; 
    [three release]; 

    NSString *ccName = @"Constitution Center"; 
    NSString *fcName = @"Franklin Court"; 

    NSString *element; 
    int j = 0; 
    for (element in sites) 
    { 
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 

    //setframe (where on screen) 
    //separation is 15px past the width (45-30) 
    button.frame = CGRectMake(a, b + (j*45), c, d); 

    [button setTitle:element forState:UIControlStateNormal]; 

    button.backgroundColor = [SiteOneController myColor1]; 

    /*- (void) fooFirstInput:(NSString*) first secondInput:(NSString*) second { 
    NSLog(@"Logs %@ then %@", first, second); 
    } 
    - (void) performMethodsViaSelectors { 
    [self performSelector:@selector(fooNoInputs)]; 
    [self performSelector:@selector(fooOneInput:) withObject:@"first"]; 
    [self performSelector;@selector(fooFirstInput:secondInput:) withObject:@"first" withObject:@"second"];*/ 

    //UIView *old = self.view; 

    if (element == ccName) { 
    [button addTarget:self action:@selector(showCCView:) 
    forControlEvents:UIControlEventTouchUpInside]; 
    } 
    else if (element == fcName) { 

    } 
    else { 

    } 

    [self.view addSubview: button]; 
    j++; 
    } 

} 

// This method show the content views for each of the sites. 
+ (void) showCCView:(id) sender { 
NSLog(@"CC CLICKED"); 
//UIView *current = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 
//[current addSubview:[SiteOneController ccContent]]; 
} 

Теперь почему не метод showCCView получение вызывается при нажатии на кнопку? Что я делаю не так?

Answer 1

+ (void) showCCView:(id) sender { 
    NSLog(@"CC CLICKED"); 
    //UIView *current = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 
    //[current addSubview:[SiteOneController ccContent]]; 
} 

Потому что это метод класса, а не метод экземпляра. Измените + на -.
