求助!开发环境xcode8
,我的数据库中有两千多条数据,我在服务的设置的每页200条,我用MJRefresh
库实现上拉加载数据只加载前2页数据,再上拉后面就不加载了,请各位老师给看看代码不知是不是逻辑上有错误~!谢谢~!!
伪代码如下:
SSTQuanDataModel.h
:
@interface SSTQuanDataModel : NSObject
...
...
//总页数
@property(nonatomic,assign)NSInteger total_num;
//当前页码
@property(nonatomic,assign)NSInteger currentPage;
...
@end
SSTQuanZhiBoViewController.m
:
...
#impor “SSTQuanDataModel”
#import <MJExtension.h>
#import <MJRefresh.h>
@interface SSTQuanViewController ()<UICollectionViewDelegate,UICollectionViewDataSource>
@property(nonatomic,strong)UICollectionView *collectionVC;
@property(nonatomic,strong)NSMutableArray *quanData;
@property(nonatomic,strong)AFHTTPSessionManager *manager;
....
@end
@implementation SSTQuanViewController
....
//上拉加载数据
-(void)setupReFresh{
//上拉加载数据
self.collectionVC.mj_footer=[MJRefreshBackFooter footerWithRefreshingTarget:self refreshingAction:@selector(loadMoreData)];
}
//上拉刷新加载更多数据
-(void)loadMoreData{
SSTQuanDataModel *sd=[[SSTQuanDataModel alloc]init];
sd.currentPage=1;
NSString *url =[NSString stringWithFormat:@"http://127.0.0.1:8000/api/v1/coupon/?page=%ld",++sd.currentPage] ;
[self.manager GET:url parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSArray *add=[SSTQuanDataModel mj_objectArrayWithKeyValuesArray:responseObject[@"results"]];
//下拉刷新后将第二页的数据添加到self.quanData的后面
[self.quanData addObjectsFromArray:add];
[self.collectionVC reloadData];
//停止刷新表格
if(self.quanData.count==sd.total_num){
[self.collectionVC.mj_footer endRefreshingWithNoMoreData];
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
//显示失败信息
[SVProgressHUD showErrorWithStatus:@"数据加载失败!"];
}];
}
....
@end
感谢 @空心菜舅舅 确实是自己在loadMoreData
方法中sd.currentPage=1
这句表达式的问题,这句应该在第一次加载网络请求的时候设置,自己的疏忽,非常感谢各位兄台不吝指教~!
sd.currentPage=1;
MoreData를 로드할 때마다 첫 번째 페이지로 초기화되기 때문에 항상 두 번째 페이지의 데이터가 나옵니다...MJ와는 전혀 상관없는 논리적인 문제이겠죠, MJ는 그저 컨트롤일 뿐입니다
어떻게 수정하나요? ?
