多种cell混合使用

有时候我们会碰到一个tableView上有多种cell，这个时候就需要定义多种cell，根据条件判断，当满足某个条件的时候选择某个cell

先看plist文件:

Person.h

 #import <Foundation/Foundation.h>

 @interface Person : NSObject

 @property (nonatomic, copy) NSString *name;

 @property (nonatomic, copy) NSString *status;

 @property (nonatomic, copy) NSString *imageName;

 @property (nonatomic, copy) NSString *type;

 @end

LabelCell.h

 #import <UIKit/UIKit.h>

 @interface LabelCell : UITableViewCell

 // nameLabel

 @property (nonatomic, strong) UILabel *nameLabel;

 // statusLabel

 @property (nonatomic, strong) UILabel *statusLabel;

 @end

LabelCell.m

 #import "LabelCell.h"

 @implementation LabelCell

 - (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {

     self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];

     if (self) {

         [self add];

     }

     return self;

 }

 - (void)add {

     self.nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(, , , )];

 //    self.nameLabel.backgroundColor = [UIColor redColor];

     self.nameLabel.font = [UIFont fontWithName:@"Helvetica" size:];

 //    NSLog(@"%@", [UIFont familyNames]);

     [self.contentView addSubview:self.nameLabel];

     self.statusLabel = [[UILabel alloc] initWithFrame:CGRectMake(, CGRectGetMaxY(self.nameLabel.frame) + , , )];

 //    self.statusLabel.backgroundColor = [UIColor greenColor];

     self.statusLabel.font = [UIFont systemFontOfSize:];

     [self.contentView addSubview:self.statusLabel];

 }

 @end

ImageViewCell.h

 #import <UIKit/UIKit.h>

 @interface ImageViewCell : UITableViewCell

 @property (nonatomic, strong) UIImageView *myImageView;

 @property (nonatomic, strong) UILabel *nameLabel;

 @property (nonatomic, strong) UILabel *statusLabel;

 @end

ImageViewCell.m

 #import "ImageViewCell.h"

 @implementation ImageViewCell

 - (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {

     self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];

     if (self) {

         [self add];

     }

     return self;

 }

 - (void)add {

     self.nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(, , , )];

 //    self.nameLabel.backgroundColor = [UIColor orangeColor];

     self.nameLabel.font = [UIFont fontWithName:@"Helvetica" size:];

     [self.contentView addSubview:self.nameLabel];

     self.statusLabel = [[UILabel alloc] initWithFrame:CGRectMake(, CGRectGetMaxY(self.nameLabel.frame) + , , )];

     self.statusLabel.numberOfLines = ;

 //    self.statusLabel.backgroundColor = [UIColor blueColor];

     self.statusLabel.font = [UIFont systemFontOfSize:];

     [self.contentView addSubview:self.statusLabel];

     self.myImageView = [[UIImageView alloc] initWithFrame:CGRectMake(CGRectGetMaxX(self.nameLabel.frame) + , , , )];

 //    self.myImageView.backgroundColor = [UIColor purpleColor];

     [self.contentView addSubview:self.myImageView];

 }

 @end

RootTableViewController.m

 #import "RootTableViewController.h"

 #import "Person.h"

 #import "LabelCell.h"

 #import "ImageViewCell.h"

 @interface RootTableViewController ()

 // 声明大数组存放所有数据

 @property (nonatomic, strong) NSMutableArray *allPersonArray;

 @end

 @implementation RootTableViewController

 // 懒加载

 - (NSMutableArray *)allPersonArray {

     if (_allPersonArray == nil) {

         _allPersonArray = [NSMutableArray array];

     }

     return _allPersonArray;

 }

 - (void)viewDidLoad {

     [super viewDidLoad];

     self.title = @"多种cell";

     self.navigationController.navigationBar.barTintColor = [UIColor lightGrayColor];

     // 读取数据

     [self handleData];

     // 第一步：注册cell,有几个自定义cell就注册几个

     [self.tableView registerClass:[LabelCell class] forCellReuseIdentifier:@"labelCell"];

     [self.tableView registerClass:[ImageViewCell class] forCellReuseIdentifier:@"imageCell"];

 }

 // 读取数据

 - (void)handleData {

     // 1. 获取文件路径

     NSString *path = [[NSBundle mainBundle] pathForResource:@"person.plist" ofType:nil];

     // 2. 根据路径读取数据

     NSArray *dataArray = [NSArray arrayWithContentsOfFile:path];

     //NSLog(@"%@", dataArray);

     // 3.将数据转为model对象

     for (NSDictionary *dict in dataArray) {

         // 3.1 创建model对象

         Person *person = [[Person alloc] init];

         // 3.2 使用KVC赋值

         [person setValuesForKeysWithDictionary:dict];

         // 3.3 将model对象存放到大数组中

         [self.allPersonArray addObject:person];

     }

     //NSLog(@"%@", self.allPersonArray);

 }

 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

     return ;

 }

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

     return self.allPersonArray.count;

 }

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

     // 第二步：重用cell

     // 获取数据model

     Person *person = self.allPersonArray[indexPath.row];

     // 判断数据类型，重用相应的cell对象

     if ([person.type isEqualToString:@""]) {

         LabelCell *cell = [tableView dequeueReusableCellWithIdentifier:@"labelCell" forIndexPath:indexPath];

         cell.nameLabel.text = person.name;

         cell.statusLabel.text = person.status;

         return cell;

     }

     ImageViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"imageCell" forIndexPath:indexPath];

     cell.nameLabel.text = person.name;

     cell.statusLabel.text = person.status;

     cell.myImageView.image = [UIImage imageNamed:person.imageName];

     return cell;

 }

 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

     return ;

 }
