ROOTViewController直接設置爲跟視圖控制器.APPdelegate中的代碼我就不貼了.一下爲.h中的文件
代碼註釋已經非常清楚,其中所說的菊花就是動態的刷新圖.
#import <UIKit/UIKit.h>
@interface RootViewController : UIViewController<UITableViewDelegate,UITableViewDataSource>
{
//表格數據
NSMutableArray *tableData;
//上拉時添加的數組內的數據
NSMutableArray *tableMoreData;
//數據數量
NSUInteger dataNumber;
//加載狀態
BOOL _loadingMore;
}
@property(nonatomic,retain)UITableView *table;
//創建盛放菊花的視圖,也可以偵測上拉
- (void) createTableFooter;
//開始加載數據
- (void) loadDataBegin;
- (void) loadDataing;
- (void) loadDataEnd;
@end
以下爲.m中的文件
#import "RootViewController.h"
@interface RootViewController ()
