iOS利用MJRefresh实现自定义刷新动画效果

#import"MJRefresh.h"

//自定义一个方法实现

- (void)prepareRefresh

{

 NSMutableArray *headerImages = [NSMutableArray array];

 for(inti =1; i <=4; i++) {

  UIImage *image = [UIImage imageNamed:[NSStringstringWithFormat:@"topload%d",i]];

  [headerImages addObject:image];

 }

 MJRefreshGifHeader *gifHeader = [MJRefreshGifHeaderheaderWithRefreshingBlock:^{

//下拉刷新要做的操作.

 }];

 gifHeader.stateLabel.hidden = YES;

 gifHeader.lastUpdatedTimeLabel.hidden = YES;

 [gifHeader setImages:@[headerImages[0]]forState:MJRefreshStateIdle];

 [gifHeader setImages:headerImages forState:MJRefreshStateRefreshing];

 _tableView.header = gifHeader;

 NSMutableArray *footerImages = [NSMutableArray array];

 for(inti =1; i <=4; i++) {

  UIImage *image = [UIImage imageNamed:[NSStringstringWithFormat:@"footerload%d",i]];

  [footerImages addObject:image];

 }

 MJRefreshAutoGifFooter *gifFooter = [MJRefreshAutoGifFooterfooterWithRefreshingBlock:^{

//上拉加载需要做的操作.

 }];

 gifFooter.stateLabel.hidden = YES;

 gifFooter.refreshingTitleHidden = YES;

 [gifFooter setImages:@[footerImages[0]]forState:MJRefreshStateIdle];

 [gifFooter setImages:footerImages forState:MJRefreshStateRefreshing];

 _tableView.footer = gifFooter;

}

[_tableView.header endRefreshing];//下拉刷新数据完成时写上

[_tableView.footer endRefreshing];//上拉加载数据完成时写上
