EGOTableViewPullRefresh 是fork EGOTableViewPullRefresh開源類庫進行的改進，添加了上提加載更多效果。同時也可以通過一個按鈕的觸發(fā)刷新事件，但是刷新的時候不能跳到top，為了動態(tài)展示，再刷新的時候按鈕旋轉(zhuǎn)，然后跳轉(zhuǎn)回到頂部！如下如圖

關(guān)于EGOTableViewPullRefresh可以參照http://blog.csdn.net/duxinfeng2010/article/details/9007311，翻譯過的用法，在這個Demo基礎(chǔ)上進行修改，點擊Demo下載；

1、給工程添加一個導(dǎo)航欄，在application: didFinishLaunchingWithOptions:方法中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
//    [[UINavigationBar appearance] setBackgroundImage:[UIImage p_w_picpathNamed:@"navbar.png"] forBarMetrics:UIBarMetricsDefault];
               
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.viewController];
    self.window.rootViewController = nav;
    [self.window makeKeyAndVisible];
    return YES;
}

2、在ViewDidLoad方法中，修改背景圖片，添加刷新按鈕

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationController.navigationBar.tintColor = [UIColor colorWithPatternImage:[UIImage p_w_picpathNamed:@"navbar.png"]];
         
    self.pullTableView.pullArrowImage = [UIImage p_w_picpathNamed:@"blackArrow"];
//    self.pullTableView.pullBackgroundColor = [UIColor yellowColor];
    self.pullTableView.pullTextColor = [UIColor blackColor];
         
    CGRect rect = CGRectMake(0, 0, 44, 44);
    UIButton *refreshBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    refreshBtn.frame = rect;
    [refreshBtn setBackgroundImage:[UIImage p_w_picpathNamed:@"button_refresh"] forState:UIControlStateNormal];
    [refreshBtn addTarget:self action:@selector(refresh:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc] initWithCustomView:refreshBtn];
    self.navigationItem.leftBarButtonItem = refreshItem;
         
}
