warning 1.导入cell头文件

import "MyTableViewCell.h"

import "MyTableViewCell2.h"

@interface RootViewController () <UITableViewDataSource, UITableViewDelegate>
@property (nonatomic, retain) NSArray *arr;
@end

@implementation RootViewController

  • (void)dealloc
    {

    [_arr release];
[super dealloc];

    }

  • (void)viewDidLoad {

    [super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
self.title = @"自定义Cell";

// tableView

tableView.delegate = self;
tableView.dataSource = self;
[self.view addSubview:tableView];
[tableView release];

// 获取数据
NSString *path = [[NSBundle mainBundle] pathForResource:@"ContactList" ofType:@"plist"];
self.arr = [NSArray arrayWithContentsOfFile:path];

}

  • (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {
    return _arr.count;
    }
  • (UITableViewCell )tableView:(UITableView )tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {

if 0

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
if (!cell) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"] autorelease];
}
cell.textLabel.text = _arr[indexPath.row][@"name"];
cell.detailTextLabel.text = _arr[indexPath.row][@"phone"];

endif

if 0

warning 2.使用自定义cell类型获取cell

MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
if (!cell) {

warning 3.创建自定义cell

    cell = [[[MyTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"] autorelease];
}
NSDictionary *dic = _arr[indexPath.row];
cell.nameLabel.text = dic[@"name"];
cell.sexLabel.text = dic[@"sex"];
cell.phoneLabel.text = dic[@"phone"];
cell.hobbyLabel.text = dic[@"hobby"];

endif


if (indexPath.row % 2 != 0) {
    
    MyTableViewCell2 *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
    if (!cell) {
        cell = [[MyTableViewCell2 alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];
    }
    NSDictionary *dic = _arr[indexPath.row];
    cell.nameLabel.text = dic[@"name"];
    cell.sexLabel.text = dic[@"sex"];
    cell.numberLabel.text = dic[@"number"];
    cell.phoneLabel.text = dic[@"phone"];
    cell.hobbyLabel.text = dic[@"hobby"];
    
    return cell;
} else {
    MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell1"];
