iOS開辟之UITableView與UISearchController完成搜刮及上拉加載,下拉刷新實例代碼

編輯:IOS開發綜合

空話不多說了,直接給年夜家貼代碼了。

詳細代碼以下所示:

#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 = @"美食家";
}
#pragma mark - 導航
-(void)createNa{
UIBarButtonItem *rightItem = [[UIBarButtonItem alloc]initWithTitle:@"Edit" style:UIBarButtonItemStylePlain target:self action:@selector(tableEdit:)];
self.navigationItem.rightBarButtonItem = rightItem;
self.title = @"美食家";
}
// 點擊導航右邊編纂按鈕時,讓表格可編纂
-(void)tableEdit:(UIBarButtonItem *) btnItem{
// if (self.myTable.editing == NO ) { // 沒有處於編纂狀況,導航按鈕文字為“Edit”
// // 點擊“編纂”文字,讓表格處於編纂狀況,並把按鈕的文字修正為“Done"
// self.myTable.editing = YES;
// 
// }else{
// // 編纂狀況下,點擊”Done"按鈕,撤消表格的編纂狀況,修正導航按鈕文字為"Edit"
// self.myTable.editing = NO;
// btnItem.title = @"Edit" ;
// self.navigationItem.rightBarButtonItems = @[btnItem];

}
