自定义cell

思路就是创建模型，自定义cell，然后在主控制器中完成，首先要观察plist文件：

Contact.h

 #import <Foundation/Foundation.h>

 @interface Contact : NSObject

 @property (nonatomic, copy) NSString *name;
 @property (nonatomic, copy) NSString *phoneNum;
 @property (nonatomic, copy) NSString *imageName;

 @end

RootCell.h

 #import <UIKit/UIKit.h>

 @interface RootCell : UITableViewCell

 // 联系人头像
 @property (nonatomic, strong) UIImageView *headerImageView;

 // 姓名
 @property (nonatomic, strong) UILabel *nameLabel;

 // 电话号码
 @property (nonatomic, strong) UILabel *phoneLabel;

 @end

RootCell.m

 #import "RootCell.h"

 @implementation RootCell

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

     self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
     if (self) {
         // 初始化子视图
         [self initLayout];
     }
     return self;
 }

 // 布局
 - (void)initLayout {

     // 头像
     self.headerImageView = [[UIImageView alloc] initWithFrame:CGRectMake(, , , )];
     //self.headerImageView.backgroundColor = [UIColor orangeColor];
     self.headerImageView.layer.cornerRadius = CGRectGetWidth(self.headerImageView.frame) / ;
     self.headerImageView.layer.masksToBounds = YES;

     // cell提供了一个contentView的属性，专门用来自定义cell，防止在cell布局的时候发生布局紊乱，记得将子控件添加到contentView上
     [self.contentView addSubview:self.headerImageView];

     // 姓名
     self.nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(CGRectGetMaxX(self.headerImageView.frame) + , , , )];
     //self.nameLabel.backgroundColor = [UIColor redColor];

     [self.contentView addSubview:self.nameLabel];

     // 电话号码
     self.phoneLabel = [[UILabel alloc] initWithFrame:CGRectMake(CGRectGetMinX(self.nameLabel.frame), CGRectGetMaxY(self.nameLabel.frame) + , , )];
     //self.phoneLabel.backgroundColor = [UIColor greenColor];

     [self.contentView addSubview:self.phoneLabel];
 }

 @end

RootTableViewController.m

 #import "RootTableViewController.h"
 #import "Contact.h"
 #import "RootCell.h"

 @interface RootTableViewController ()

 @property (nonatomic, strong) NSMutableArray *allContactsArray;

 @end

 @implementation RootTableViewController

 // 懒加载
 - (NSMutableArray *)allContactsArray {

     if (_allContactsArray == nil) {
         _allContactsArray = [NSMutableArray array];
     }
     return _allContactsArray;
 }

 - (void)viewDidLoad {
     [super viewDidLoad];

     // 设置导航栏
     self.title = @"通讯录";
     self.navigationController.navigationBar.barTintColor = [UIColor lightGrayColor];
     self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
     [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor], NSFontAttributeName : [UIFont systemFontOfSize:]}];

     // 读取plist数据
     [self handleData];

 }

 // 读取plist数据
 - (void)handleData {

     // 1.获取文件路径
     NSString *path = [[NSBundle mainBundle] pathForResource:@"Contacts.plist" ofType:nil];

     // 2.根据文件路径读取数据
     NSArray *dataArray = [NSArray arrayWithContentsOfFile:path];
 //    NSLog(@"%@", dataArray);

     // 3.将数据转换为model对象
     for (NSDictionary *dict in dataArray) {

         // 3.1 创建model对象
         Contact *contact = [[Contact alloc] init];

         // 3.2 使用kvc赋值
         [contact setValuesForKeysWithDictionary:dict];

         // 3.3 把model存放到大数组中
         [self.allContactsArray addObject:contact];
     }
     NSLog(@"%@", self.allContactsArray);
 }

 // 设置分区个数
 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

     return self.allContactsArray.count;
 }

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

     return ;
 }

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

     static NSString *identifier = @"rootCell";

     // 1.从重用队列里查找可用的cell
     RootCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

     // 2.判断如果没有可重用的cell，就自己创建
     if (!cell) {
         cell = [[RootCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier];
     }

     // 3.设置数据
     // 取出model对象
     Contact *contact = self.allContactsArray[indexPath.section];
     // 根据图片名设置头像
     cell.headerImageView.image = [UIImage imageNamed:contact.imageName];
     cell.nameLabel.text = contact.name;
     cell.phoneLabel.text = contact.phoneNum;

     return cell;
 }

 // 设置cell高度
 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

     return ;
 }

 // 取消屏幕点击效果
 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

     [tableView deselectRowAtIndexPath:indexPath animated:YES];
 }
