//自定义button
#import <UIKit/UIKit.h> @interface CKButton : UIButton @end #import "CKButton.h"
#define KTitleWidth 0.6
#define KPadding 0.1
#define KImageWidth (1-KTitleWidth -2*KPadding) @implementation CKButton - (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
//设置image
self.adjustsImageWhenDisabled=NO;
self.adjustsImageWhenHighlighted=NO;
self.imageView.contentMode=UIViewContentModeScaleAspectFit;
//设置title
[self setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
}
return self;
} -(CGRect)imageRectForContentRect:(CGRect)contentRect{
CGFloat width=contentRect.size.width;
CGFloat height=contentRect.size.height;
return CGRectMake(, , width*KImageWidth, height); } -(CGRect)titleRectForContentRect:(CGRect)contentRect{
CGFloat width=contentRect.size.width;
CGFloat height=contentRect.size.height;
return CGRectMake(width*(KImageWidth+KPadding), , width*KTitleWidth, height);
} @end

自定义cell

#import "CkCell.h"
#define KMinTag 10 @interface CkCell ()
{
CKButton *_current;
}
@end @implementation CkCell - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) { for (int i=; i<KCount; i++) {
CKButton *button=[[CKButton alloc] initWithFrame:CGRectZero];
button.tag=KMinTag+i;
[self.contentView addSubview:button];
[button addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
}
}
return self;
} -(void)setDatacell:(NSArray *)datacell{
if (_datacell!=datacell) {
[_datacell release];
_datacell=[datacell retain];
int count=self.datacell.count;
for (int i=; i<KCount; i++) {
CKButton *button=(CKButton *)[self.contentView viewWithTag:(KMinTag+i)];
if ((i<count)) {
button.hidden=NO;
NSString *temp=self.datacell[i];
[button setTitle:temp forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"radio_normal"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"radio_selected"] forState:UIControlStateSelected];
}
else{
button.hidden=YES;
}
}
}
} -(void)layoutSubviews{
[super layoutSubviews];
int width=self.contentView.bounds.size.width/KCount;
for (UIView *child in self.contentView.subviews) {
if ([child isKindOfClass:[UIButton class]]) {
int tag=child.tag-KMinTag;
if (tag>= && tag<KCount) {
child.frame=CGRectMake(tag*width, , width, KHeight);
}
}
}
} -(void)click:(CKButton *)btn{ btn.selected=!btn.selected; if (self.delegate ||[self.delegate respondsToSelector:@selector(CKCellCLick:)]) {
[self.delegate CKCellCLick:btn];
}
} - (void)dealloc
{ [_datacell release];
[super dealloc];
}
@end

封装tableview

#import <UIKit/UIKit.h>
#import "CkCell.h" @interface CKTableView : UIView<UITableViewDataSource,UITableViewDelegate>
@property(nonatomic,retain)NSArray *data;
@property(nonatomic,assign)id ckDelegate;
@end #import "CKTableView.h" @implementation CKTableView - (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
UITableView *tableview=[[UITableView alloc] initWithFrame:self.bounds style:UITableViewStylePlain];
tableview.delegate=self;
tableview.dataSource=self;
tableview.separatorStyle=UITableViewCellSeparatorStyleNone;
[self addSubview:tableview];
[tableview release];
}
return self;
} -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return ;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ int count=self.data.count/KCount;
if (!self.data.count%KCount==) {
count++;
}
return count;
} -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *cellIdentify=@"CKTableView";
CkCell *cell=[tableView dequeueReusableCellWithIdentifier:cellIdentify];
if (cell==nil) {
cell=[[[CkCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentify] autorelease] ;//注意一定要在这里加aurorelease,否则会报错,原因不明
}
cell.delegate=self.ckDelegate; int location=indexPath.row*KCount;
int length=KCount;
if (location+length>self.data.count) {
length=self.data.count-location;
}
cell.datacell=[self.data subarrayWithRange:NSMakeRange(location, length)]; return cell ;
} - (void)dealloc
{
[_data release];
[super dealloc];
} @end

viewcontroller中用法

#import <UIKit/UIKit.h>
#import "CKTableView.h" @interface CkViewController : UIViewController<CKCellDelegate> @property(nonatomic,retain)NSMutableArray *selectArrary;
@end #import "CkViewController.h" @interface CkViewController () @end @implementation CkViewController - (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor=[UIColor whiteColor];
self.selectArrary=[NSMutableArray array];
NSArray *mydata=@[@"税收优惠",@"办税指南",@"最新政策",@"政策解读",@"热点问题",@"涉税通告",@"地税新闻"];
for (int i=; i<mydata.count; i++) {
[self.selectArrary addObject:@];
}
// Do any additional setup after loading the view.
CKTableView *tableview=[[CKTableView alloc] initWithFrame:CGRectMake(, , , )];
tableview.ckDelegate=self;
tableview.data=mydata;
[self.view addSubview:tableview];
[tableview release];
} -(void)CKCellCLick:(CKButton *)btn{
NSLog(@"__>%@",btn.titleLabel.text);
} @end
