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 (int i = 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 (int i = 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
