MJRefreshHeaderView刷新集成

来源：互联网发布：php解压zip到指定目录编辑：程序博客网时间：2024/06/05 15:08

1.头文件引入

#import "MJRefresh.h"

2.在viewdidload执行方法：

[selfaddHeader];

[selfaddFooter];

3.添加方法

- (void)addFooter

{

__unsafe_unretainedxiaoxi_list *vc =self;

MJRefreshFooterView *footer = [MJRefreshFooterViewfooter];

footer.scrollView =self.mytable;

footer.beginRefreshingBlock = ^(MJRefreshBaseView *refreshView) {

_flagrefresh = YES;

[self getMessage:icount*LIMITlimit:LIMIT];

//重置刷新次数

icount++;

//模拟延迟加载数据，因此2秒后才调用）

// 这里的refreshView其实就是footer

[vc performSelector:@selector(doneWithView:)withObject:refreshViewafterDelay:0.0];

};

_footer = footer;

}

- (void)addHeader

{

__unsafe_unretainedxiaoxi_list *vc =self;

MJRefreshHeaderView *header = [MJRefreshHeaderViewheader];

header.scrollView =self.mytable;

header.beginRefreshingBlock = ^(MJRefreshBaseView *refreshView) {

_flagrefresh = NO;

[self getMessage:0limit:LIMIT];

//重置刷新次数

icount = 1;

// 这里的refreshView其实就是header

[vc performSelector:@selector(doneWithView:)withObject:refreshViewafterDelay:2.0];

};

header.endStateChangeBlock = ^(MJRefreshBaseView *refreshView) {

// 刷新完毕就会回调这个Block

};

header.refreshStateChangeBlock = ^(MJRefreshBaseView *refreshView,MJRefreshState state) {

// 控件的刷新状态切换了就会调用这个block

switch (state) {

caseMJRefreshStateNormal:

NSLog(@"%@----切换到：普通状态", refreshView.class);

break;

caseMJRefreshStatePulling:

NSLog(@"%@----切换到：松开即可刷新的状态", refreshView.class);

break;

caseMJRefreshStateRefreshing:

NSLog(@"%@----切换到：正在刷新状态", refreshView.class);

break;

default:

break;

}

};

[header beginRefreshing];

_header = header;

}

- (void)doneWithView:(MJRefreshBaseView *)refreshView

{

if(_total<icount*LIMIT&&_total!=0)

{

[[NSNotificationCenterdefaultCenter]postNotificationName:@"changetext"object:nil];

}

// 刷新表格

[self.mytablereloadData];

// (最好在刷新表格后调用)调用endRefreshing可以结束刷新状态

[refreshView endRefreshing];

}

4.取数据

-(void)getMessage:(int)start limit:(int)limit{

MBProgressHUD *hud= [[MBProgressHUDalloc]initWithView:self.view];

hud.labelText = @"正在努力加载";

[self.viewaddSubview:hud];

[hud show:YES];

NSString *url = [NSStringstringWithFormat:@"%@/adnotification/queryNotificationList?start=%d&limit=%d&corpid=%@",BASEURL,start,limit,CORPID];

AFHTTPRequestOperationManager *managers = [AFHTTPRequestOperationManagermanager];

managers.responseSerializer.acceptableContentTypes = [NSSetsetWithObject:@"text/html"];

[managers GET:url parameters:nil

success:^(AFHTTPRequestOperation *operation,id responseObject)

{

[hud hide:YES];

[hud removeFromSuperview];

dataSource_dic = (NSMutableDictionary *)responseObject;

_total = [[dataSource_dicobjectForKey:@"total"]integerValue];

if([dataSourcecount]*49 >DEVICE_HEIGHT-60){

self.mytable.frame =CGRectMake(0,0,320,DEVICE_HEIGHT-60);

}

else{

self.mytable.frame =CGRectMake(0,0,320, [dataSourcecount]*49);

}

if(!_flagrefresh)

{

[dataSource removeAllObjects];

}

[dataSource addObjectsFromArray:dataSource_dic[@"data"]]; （重点）

[self.mytablereloadData];

}

failure:^(AFHTTPRequestOperation *operation,NSError *error)

{

[hud hide:YES];

[hud removeFromSuperview];

}];

}
