iOS开发之UITableView与UISearchController实现搜索及上拉加载，下拉刷新实例代码
废话不多说了，直接给大家贴代码了。
具体代码如下所示：
#import"ViewController.h"
#import"TuanGouModel.h"
#import"TuanGouTableViewCell.h"
#definekDeviceWidth[UIScreenmainScreen].bounds.size.width
#definekDeviceHeight[UIScreenmainScreen].bounds.size.height
@interfaceViewController()<UITableViewDelegate,UITableViewDataSource,UISearchResultsUpdating>
{
UISearchController*_sscller;
}
@property(nonatomic,strong)NSMutableArray*secArrM;
@property(nonatomic,strong)NSMutableArray*tuanGouArrM;
@property(nonatomic,strong)UITableView*myTable;
@end
@implementationViewController
-(void)viewDidLoad{
[superviewDidLoad];

}

}
//点击导航右侧编辑按钮时，让表格可编辑
-(void)tableEdit:(UIBarButtonItem*)btnItem{
//if(self.myTable.editing==NO){//没有处于编辑状态，导航按钮文字为“Edit”
////点击“编辑”文字，让表格处于编辑状态，并把按钮的文字修改为“Done"
//self.myTable.editing=YES;
//
//}else{
////编辑状态下，点击”Done"按钮，取消表格的编辑状态，修改导航按钮文字为"Edit"
//self.myTable.editing=NO;
//btnItem.title=@"Edit";
//self.navigationItem.rightBarButtonItems=@[btnItem];
