一个分段视图使用的例子

参考：https://github.com/HeshamMegid/HMSegmentedControl

#import "HMSegmentedControl.h"

使用方法：

@interface ARWContactsSegmentedControlViewController ()

@property (nonatomic, strong) HMSegmentedControl *topSegmentedControl;
@property (nonatomic, strong) UIScrollView *contentScrollView;

@property (nonatomic, strong) ARWRecommendView *recommendView;
@property (nonatomic, strong) ARWContactsView *contactView;
@property (nonatomic, strong) ARWFriendSearchDisplayController *recommendSearchController;
@property (nonatomic, strong) ARWFriendSearchDisplayController *contactSearchController;

@end

@implementation ARWContactsSegmentedControlViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.title = @"Contacts";
    
    [self configureScrollView];
    
    //推荐搜索
    self.recommendSearchController = [[ARWFriendSearchDisplayController alloc] initWithSearchBar:_recommendView.searchBar contentsController:self];
    [self.recommendSearchController setDelegate: self];
    
    
    //联系人搜索
