为了使代码结构更加合理、精简，本人将M层和V层进行了合并，本文主要介绍tableView的单选功能实现和MV合并，代码如下：
类名 - View.h
#import <UIKit/UIKit.h>
/**
* ----- Model -----
*/
@interface Model : NSObject
@property (nonatomic,strong) NSString *content;
@end
/**
* ----- View -----
*/
@interface View : UITableViewCell
//#import "View.xib"
@property (nonatomic,strong)Model *model;
@property (weak, nonatomic) IBOutlet UIButton *selectBtn;// - xib -
+(NSString *)cellID;
@end
类名 - View.m
#import "View.h"
/**
* ----- Model -----
*/
@implementation Model
@end
/**
* ----- View -----
*/
@interface View ()
@property (weak, nonatomic) IBOutlet UILabel *selectContent;// - xib -
@end
@implementation View
+(NSString *)cellID
{
static NSString * const ID = @"ViewID";
return ID;
}
-(void)setModel:(Model *)model{
_selectContent.text = model.content;
_selectBtn.selected = NO;
}
@end
类名 - KGDemo.h
#import <UIKit/UIKit.h>
/**
* ----- Controller -----
*/
@interface KGDemo : UIViewController
@end
类名 - KGDemo.m
#import "KGDemo.h"
#import "View.h"
/**
* ----- Controller -----
*/
@interface KGDemo ()<UITableViewDelegate,UITableViewDataSource>
{
NSIndexPath *_selectIndexPath;//选中cell的indexPath
}
@property (weak, nonatomic) IBOutlet UITableView *KGDemoTv;// - xib 设置delegate、dataSource-
@end
@implementation KGDemo
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"tableView单选功能";
//注册cell
[_KGDemoTv registerNib:[UINib nibWithNibName:NSStringFromClass([View class] ) bundle:nil] forCellReuseIdentifier:[View cellID]];
}
#pragma mark - UITableViewDelegate
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
_selectIndexPath = indexPath;
[_KGDemoTv reloadData];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
View *cell = [tableView dequeueReusableCellWithIdentifier:[View cellID]];
Model *model = [Model new];
model.content = [NSString stringWithFormat:@"%ld",(long)indexPath.row];
cell.model = model;
if (_selectIndexPath.row == indexPath.row) {
cell.selectBtn.selected = YES;
}
return cell;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 4;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 60;
}
@end
