本文主要介绍iOS 利用MJRefresh实现自定义动画的上拉刷新下拉加载效果,一般的类型(包括更新时间与loading图案)这里不做介绍.
要想实现此功能,首先得有一套load的图片数组.
接下来就是实现过程:
引入头文件:
#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;
}
最后记得在数据加载完成时停掉loading[_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
