iOS development of UITableView and UISearchController search and pull up load pull down refresh instance code

Without further ado, I'm just going to post the code.

The specific code is as follows:

#import "ViewController.h"
#import "TuanGouModel.h"
#import "TuanGouTableViewCell.h"
#define kDeviceWidth [UIScreen mainScreen].bounds.size.width
#define kDeviceHeight [UIScreen mainScreen].bounds.size.height
@interface ViewController ()<UITableViewDelegate,UITableViewDataSource,UISearchResultsUpdating>
{
UISearchController * _sscller;
}
@property(nonatomic,strong)NSMutableArray* secArrM;
@property(nonatomic,strong) NSMutableArray* tuanGouArrM;
@property(nonatomic,strong)UITableView* myTable;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self createNa];
self.myTable.backgroundColor = [UIColor lightGrayColor];
[self createsecB];
[self setupRefresh];
self.title = @" The gourmet ";
}
#pragma mark -  navigation 
-(void)createNa{
UIBarButtonItem *rightItem = [[UIBarButtonItem alloc]initWithTitle:@"Edit" style:UIBarButtonItemStylePlain target:self action:@selector(tableEdit:)];
self.navigationItem.rightBarButtonItem = rightItem;
self.title = @" The gourmet ";
}
//  Click the edit button on the right side of the navigation to make the table editable 
-(void)tableEdit:(UIBarButtonItem *) btnItem{
// if (self.myTable.editing == NO ) { //  Not in edit state, navigation button text is" Edit " 
// //  Click "edit" to make the table in the edit state and change the text of the button to" Done"
// self.myTable.editing = YES;
// 
// }else{
// //  In edit mode, click" Done" Button to cancel the editing state of the form and modify the text of the navigation button as "Edit"
// self.myTable.editing = NO;
// btnItem.title = @"Edit" ;
// self.navigationItem.rightBarButtonItems = @[btnItem];
// }
}

The above code is hi this site to introduce the iOS development of UITableView and UISearchController search and pull up load, pull down refresh instance code, hope to help you!
