CYPullRefresh

use pull-refresh and load-more easily

basic use

First, It's very easy to implement pull-refresh and load-more feature by CYPullRefresh. Just import UIScrollView+CYPullRefresh category. Init by two lines of code.

- (void)cy_addPullDownHanlder:(CYPullRefreshBlock)handler topView:(UIView<CYPullRefreshViewProtocol> *)topView;
- (void)cy_addPullUpHandler:(CYPullRefreshBlock)handler bottomView:(UIView<CYPullRefreshViewProtocol> *)bottomView;

sample

see demo project

    CYPullRefreshSimpleBottomView *bottomView = [[CYPullRefreshSimpleBottomView alloc] init];
    CYPullRefreshSimpleTopView *topView = [[CYPullRefreshSimpleTopView alloc] init];

    __weak typeof(&*self) weakself = self;
    UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    tableView.backgroundView = nil;
    tableView.delegate = self;
    tableView.dataSource = self;
    [tableView cy_addPullDownHanlder:^{
        [weakself reloadData];
    } topView:topView];
    [tableView cy_addPullUpHandler:^{
        [weakself loadMore];
    } bottomView:bottomView];
    [tableView cy_setPullUpEnable:NO];
    [self.view addSubview:tableView];
    _theTableView = tableView;

    [_theTableView cy_triggerLoadWithState:CYLoadStatePullDown];

reloadData

add this after finish loading data

    [_theTableView reloadData];
    [_theTableView cy_stopLoad];
    [_theTableView cy_setHasMoreData:_dataArray.count >= _limitNum ? YES : NO];
    [_theTableView cy_setPullUpEnable:YES];

loadMore

add this after finish loading data

    [_theTableView reloadData];
    [_theTableView cy_stopLoad];
    [_theTableView cy_setHasMoreData:dataArray.count >= _limitNum ? YES : NO];

custom loading view

You can custom your pull refresh view by creating a custom view confirming to CYPullRefreshViewProtocol. For different state, load different UI.For more information, see CYPullRefreshSimpleTopView and CYPullRefreshSimpleBottomView.

In this way, you can do high customization without changing source code of CYPullRefresh.
