iOS开发 自定义tableView样式(使用代码)

自定义tableView样式有两种方法,一种是用代码写cell的subView,另一种是导入nib文件(就是用Interface Builder设计),这篇笔记记录的是代码的方法.
1、新建一个Single View Application 项目,如前文,只选Use Automatic Reference Counting.
2、打开PDViewController.xib,拖进一个Table View,选中Table View,打开Connections inspector,拖动delegate和dataSource右边的小圆到File’s Owner.
3、新建文件,选Cocoa Touch—-Objective-C class,输入类名,我这是MyCell,Subclass of UItableViewCell.生成MyCell.h和MyCell.m两文件。
MyCell.h:


#import 

@interface MyCell : UITableViewCell
@property (copy,nonatomic) NSString *name;
@property (copy,nonatomic) NSString *color;
@end

MyCell.m:


#import "MyCell.h"
#define kNameTag 1
#define kColorTag 2
@implementation MyCell
@synthesize name=_name,color=_color;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
        CGRect nameLableRect=CGRectMake(0, 5, 100, 15);
        //定义一个距形,位置0,5,宽100高15,就是绝对定位
        UILabel *nameLable=[[UILabel alloc] initWithFrame:nameLableRect];
        //在距形定义的位置实例化一个UILable对象
        nameLable.tag=kNameTag;
        [self.contentView addSubview:nameLable];
        
        
        CGRect colorLableRect=CGRectMake(0, 30, 100, 15);
        //定义一个距形,距离上面的nameLable 10
        UILabel *colorLable=[[UILabel alloc] initWithFrame:colorLableRect];
        //在距形定义的位置实例化一个UILable对象
        colorLable.tag=kColorTag;
        [self.contentView addSubview:colorLable];
        
        
    }
    return self;
}

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

    // Configure the view for the selected state
}
//自己写name和color的setter方法
-(void)setName:(NSString *)name
{
    if(![name isEqualToString:_name])
    {
        _name=[name copy];
        UILabel * nameLable=(UILabel *)[self.contentView viewWithTag:kNameTag];
        //通过viewWithTag方法得到UILable
        nameLable.text=_name;
        
    }
}
-(void)setColor:(NSString *)color
{
    if(![color isEqualToString:_color])
    {
        _color=[color copy];
        UILabel * colorLable=(UILabel *)[self.contentView viewWithTag:kColorTag];
        colorLable.text=_color;
        
    }
}


@end

PDViewControllor.h:


#import 

@interface PDViewController : UIViewController
//简单起见,不再定义数据,每行数据都一样
@end


PDViewController.m


#import "PDViewController.h"
#import "MyCell.h"
@implementation PDViewController

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Release any cached data, images, etc that aren't in use.
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

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

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

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

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

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 100;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString * tableIdentifier=@"Custom table";
    MyCell *cell=[tableView dequeueReusableCellWithIdentifier:tableIdentifier];
    if(cell==nil)
    {
        cell=[[MyCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:tableIdentifier];
        
    }
    cell.name=@"标题";
    cell.color=@"颜色";
    //不再定义数据,每行都一样
    return cell;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 60;
}

@end
