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 ;
 }
