如何使用自定義UIButtons獲得UISegementedControl功能？

Question

我已經創建了我自己的自定義過濾器視圖，我想像UISegmentedControl一樣。我已經將它設置爲一個視圖，然後是3個UIButton。我想知道如何做到這一點，所以當點擊其他兩個被取消選擇和api調用該按鈕，然後重新加載它下面的UICollectionView。

下面是我的觀點與3按鈕的圖片，希望能更好地解釋我正在嘗試做什麼。

連接所有的按鈕來此IBAction並定義標籤每個按鈕。

- (IBAction)pressButton:(id)sender { 

    UIButton* button1 = (UIButton*)[self.view viewWithTag:99]; 
    UIButton* button2 = (UIButton*)[self.view viewWithTag:100]; 
    UIButton* button3 = (UIButton*)[self.view viewWithTag:101]; 

    [button1 setEnabled:NO]; 
    [button2 setEnabled:NO]; 
    [button3 setEnabled:NO]; 

    [button1 setSelected:NO]; 
    [button2 setSelected:NO]; 
    [button3 setSelected:NO]; 

    if([sender tag]==99){ 
     [button1 setSelected:YES]; 
     [button1 setEnabled:YES]; 
    }else if([sender tag]==100){ 
     [button2 setSelected:YES]; 
     [button2 setEnabled:YES]; 
    }else{ 
     [button3 setSelected:YES]; 
     [button3 setEnabled:YES]; 
    } 

}
