iOS 用block反向传值-视频列表进入详情后返回刷新数据

一.在视频列表MyVideoNewController界面点击进入视频详情，增加回调处理事件刷新界面，并且点击后让视频浏览数+1

//添加一项

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

MyVideoDetailController *myvideoVc=[[MyVideoDetailController alloc] init];

myShotsList *myshot =[[myShotsList alloc] init];

myshot=self.arrList[indexPath.row];

//点击了就代表浏览了hit数要+1

NSInteger hitPlus = [myshot.hit integerValue];

hitPlus += 1; //点击后让视频浏览数+1

myshot.hit = [NSString stringWithFormat:@"%ld",(long)hitPlus];

[self.tableview reloadData];

//删除视频回调

__weak typeof (MyVideoNewController *) weakSelf = self;

[myvideoVc setDeleteVideoBlcok:^{

[weakSelf.arrList removeObjectAtIndex:indexPath.row];

[weakSelf.tableview reloadData];

}];

myvideoVc.myNo=myshot.myNo;

[self.navigationController pushViewController:myvideoVc animated:YES];

}

二. 视频详情界面删除视频后block反向传值；

// 删除视频后回调

@property (nonatomic,copy) void (^DeleteVideoBlcok)();

// 删除视频后回调

if (self.DeleteVideoBlcok) {

DSLog(@"删除视频成功回调");

self.DeleteVideoBlcok();

}
