Ios 分段控件不调用方法

我在实现分段控制时遇到问题。我相信我已经把所有的东西都连接好了，但是当我点击分段控件的任一侧时，方法没有被调用

下面是分段控件的连接检查器

您需要将控件连接到“值更改”事件，而不是“内部修补”事件。

段控件不是内部修补，而是值更改。这不是Xcode问题，而是API使用问题。（我对“但我正在使用Xcode”参数不感兴趣，因为它是无效的。）这是有效的！它确实让我联系上了“内部事件润色”，不知道如果它什么都不做为什么。非常感谢你们，当你们学习的时候，总是有一些小东西。

@interface Friends ()

@end

@implementation ContactInfo

@end

@implementation Friends
@synthesize segmentedControl;




- (void)viewDidLoad
{
    _friendList = [[NSMutableArray alloc] init];
    _contactList = [[NSMutableArray alloc] init];
    [self AddClicked];
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (void) dealloc
{
    [segmentedControl release];
    [_friendList release];
    [_contactList release];
    [super dealloc];
}

- (IBAction)segmentSwitch {
    switch (self.segmentedControl.selectedSegmentIndex) {
        case 0:
            [self AddClicked];
            break;
        case 1:
            [self InviteClicked];
            break;

        default:
            break;
    }

}
