iOS MJRefresh上拉加载更多

1.导入MJRefresh包

2.在类中引入：#import "MJRefresh.h"

3.添加footerView

添加加载更多的UI样式：

MJRefreshAutoNormalFooter *footer = [MJRefreshAutoNormalFooter footerWithRefreshingTarget:self refreshingAction:@selector(loadMoreData)];

myTableView.footer = footer;

[footer setTitle:@"正在加载中" forState:MJRefreshStateRefreshing];

[footer setTitle:@"" forState:MJRefreshStateIdle];

footer.stateLabel.font = [UIFontsystemFontOfSize:15.0f];

footer.automaticallyHidden = YES;

加载数据：

　定义全局变量：int32_t _pageNumber;

定义loadMoreData方法

- (void)loadMoreData{

UIEdgeInsets edge = _tableView.contentInset;

edge.bottom = 44;

[UIView animateWithDuration:0.2 animations:^{

_tableView.contentInset = edge;

}];

[self loadDataWithPage:_pageNumber];

}

4.数据返回处理，排重

//排重数据

for (Model *Model1 in resultArray) {

BOOL isExist = NO;

for (Model *Model in _publish) {

if (Model.positionId == Model1.positionId) {

isExist = YES;

break;

}

}

if (!isExist) {

[_publish addObject:Model1];

}

}

　　结束刷新

if(_tableView.footer.isRefreshing){

[_tableView.footer endRefreshing];

}

//当数据小于5条，没有下拉刷新

if (_publishPositions.count < 5) {

[_tableView.footer noticeNoMoreData];

_tableView.footer.hidden = YES;

}
