本章实现效果:

我们使用MVC架构来实现自定义TableView，具体的MVC介绍请自行百度，在本章中不作为主要内容讲解。

Model层：
DataSource.h

#import <Foundation/Foundation.h>

@interface DataSource : NSObject

+ (NSArray *)getUserInfo;

@end

DataSource.m

#import "DataSource.h"

@implementation DataSource

+ (NSArray *)getUserInfo {
    NSString * path = [[NSBundle mainBundle] pathForResource:@"users" ofType:@"plist"];
    NSArray * arrayReturn = [NSArray arrayWithContentsOfFile:path];
    return arrayReturn;
}

@end

View层:
CustomTableViewCell.h

#import <UIKit/UIKit.h>

@interface CustomTableViewCell : UITableViewCell

@property (nonatomic, strong) UILabel * labelName;//姓名
@property (nonatomic, strong) UILabel * labelNum; //手机号

@end

CustomTableViewCell.m

#import "CustomTableViewCell.h"

@implementation CustomTableViewCell

//重写初始化方法:将控件添加到单元格上,如果将子视图控件添加到cell上 借助contenView视图,这样的话cell上子视图会随着cell的变化而变化
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
    if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
        self.labelName = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, self.bounds.size.width-200, 40)];
        self.labelName.textColor = [UIColor cyanColor];
        self.labelName.textAlignment = NSTextAlignmentCenter;
        [self.contentView addSubview:self.labelName];

        self.labelNum = [[UILabel alloc] initWithFrame:CGRectMake(100, 40, self.bounds.size.width-200, 40)];
        self.labelNum.textColor = [UIColor greenColor];
        self.labelNum.textAlignment = NSTextAlignmentCenter;
        [self.contentView addSubview:self.labelNum];
    }
    return self;
}

- (void)awakeFromNib {
    [super awakeFromNib];
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];
}

@end

ViewController层:
ViewController.m

#import "ViewController.h"
#import "DataSource.h"
#import "CustomTableViewCell.h"
#import "TwoViewController.h"

@interface ViewController ()<
UITableViewDataSource,
UITableViewDelegate>

@property (nonatomic, strong) NSMutableArray *arrayDS;
@property (nonatomic, strong) UITableView *tableView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    [self setupDatas];
    [self setupSubviews];
}

- (void)setupDatas {
    //从Model层拿到数据
    NSArray * array = [DataSource getUserInfo];
    //把拿到的数据给我们的数据源
    self.arrayDS = [[NSMutableArray alloc] initWithArray:array];
    self.navigationItem.title = @"自定义单元格";
}

- (void)setupSubviews {
    self.automaticallyAdjustsScrollViewInsets = NO;
    self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 64, self.view.bounds.size.width, self.view.bounds.size.height-64) style:UITableViewStylePlain];
    self.tableView.delegate = self;
    self.tableView.dataSource = self;
    [self.view addSubview:self.tableView];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height-50, self.view.bounds.size.width, 50)];
    view.backgroundColor = [UIColor redColor];
    [self.view insertSubview:view aboveSubview:self.tableView];
}

#pragma mark - UITableViewDataSource
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return self.arrayDS.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString * str = nil;
    if ([[[self.arrayDS objectAtIndex:indexPath.row] objectForKey:@"phoneNum"] hasPrefix:@"100"]) {
        str = @"CustomCell";
        CustomTableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:str];
        if (cell == nil) {
            cell = [[CustomTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:str];
        }
        cell.labelName.text = [[self.arrayDS objectAtIndex:indexPath.row] objectForKey:@"personName"];
        cell.labelNum.text = [[self.arrayDS objectAtIndex:indexPath.row] objectForKey:@"phoneNum"];
        return cell;
    } else {
        str = @"SystemCell";
        UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:str];
        if (cell == nil) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:str];
        }
        cell.textLabel.text = [[self.arrayDS objectAtIndex:indexPath.row] objectForKey:@"phoneNum"];
        return cell;
    }
}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [self.tableView reloadData];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    TwoViewController *twoVC = [[TwoViewController alloc] init];
    [self.navigationController pushViewController:twoVC animated:YES];
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    return 100;
}
