一、需要一个NSObject类，该类代码如下
#import <Foundation/Foundation.h>
@interface MJSampleIndex : NSObject
@property (nonatomic, copy) NSString *title; //描述该类的title
@property (nonatomic, assign) Class controllerClass; //跳转到的controller
+ (instancetype)sampleIndexWithTitle:(NSString *)title controllerClass:(Class)controllerClass; //初始化title和controller
@end
#import "MJSampleIndex.h"
@implementation MJSampleIndex
+ (instancetype)sampleIndexWithTitle:(NSString *)title controllerClass:(Class)controllerClass
{
MJSampleIndex *si = [[self alloc] init];
si.title = title;
si.controllerClass = controllerClass;
return si;
}
@end
二、UITableViewController方法实现三个方法：
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section //tableview总行数
{
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath //根据行数绘制tableviewcell
{}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath //点击每个cell执行的事件
{}
#import "MJSampleIndexViewController.h"
#import "MJSampleIndex.h"
#import "MJTableViewController.h"
#import "MJCollectionViewController.h"
NSString *const MJSampleIndexCellIdentifier = @"Cell";
@interface MJSampleIndexViewController ()
{
NSArray *_sampleIndexs;
}
@end
@implementation MJSampleIndexViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = @"快速集成下拉刷新";
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleBordered target:nil action:nil];
// 1.注册cell
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:MJSampleIndexCellIdentifier];
// 2.初始化数据
MJSampleIndex *si1 = [MJSampleIndex sampleIndexWithTitle:@"tableView刷新演示" controllerClass:[MJTableViewController class]];
MJSampleIndex *si2 = [MJSampleIndex sampleIndexWithTitle:@"collectionView刷新演示" controllerClass:[MJCollectionViewController class]];
_sampleIndexs = @[si1, si2];
}
#pragma mark - Table view data source
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return _sampleIndexs.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MJSampleIndexCellIdentifier forIndexPath:indexPath];
// 1.取出模型
MJSampleIndex *si = _sampleIndexs[indexPath.row];
// 2.赋值
cell.textLabel.text = si.title;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// 1.取出模型
MJSampleIndex *si = _sampleIndexs[indexPath.row];
// 2.创建控制器
UIViewController *vc = [[si.controllerClass alloc] init];
vc.title = si.title;
// 3.跳转
[self.navigationController pushViewController:vc animated:YES];
}
@end
