自定义Cell几种方法

.h文件

#import <UIKit/UIKit.h>@class ImageCellStyle;@interface ActionCell : UITableViewCell@property (nonatomic, strong) ImageCellStyle *imageStyle;- (void)settingData:(ImageCellStyle *)imagecellStyle;@end

.h

#import <Foundation/Foundation.h>@interface ImageCellStyle : NSObject@property (nonatomic,copy) NSString *style;@property (nonatomic,copy) NSString *name;@property (nonatomic,copy) NSString *time;@property (nonatomic,copy) NSString *much;@property (nonatomic,copy) NSString *picture;- (instancetype) initWithDict: (NSDictionary *)dict;//对象方法+ (instancetype) weiboWithDict: (NSDictionary *)dict;//类方法@end

.m

#import "ImageCellStyle.h"@implementation ImageCellStyle-(instancetype)initWithDict:(NSDictionary *)dict {    if (self = [super init]) {         //使用KVC                 [self setValuesForKeysWithDictionary:dict];        }    return self;}+(instancetype)weiboModelWithDict:(NSDictionary *)dict{    return [[self alloc]initWithDict:dict];}@end

controller 方法
.m

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{    return 100.0f;}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{    static NSString *cellIndentifiter = @"CellIndentifiter";    ActionCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIndentifiter];    if (cell == nil) {        cell = [[ActionCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIndentifiter];    }    [cell settingData:_image];    return cell;}

第二种通过xib创建
1、新建类，基于UITableViewCell
例如 @interface CellSearch : UITableViewCell

2、新建空 xib 文件
例如命名为 CellSearch.xib （名字要跟类名一样）
拖一个UITableViewCell控件到xib中
（你可以在这个cell里面放你想放的东东）

3、使用
经过1、2步，自定义的cell已经建好了
在cellForRowAtIndexPath 方法中使用

CellSearch *cell = [tableView dequeueReusableCellWithIdentifier:@”CellSearch”];
if(!cell) {
cell = [[[NSBundle mainBundle] loadNibNamed:@”CellSearch” owner:self options:nil]lastObject];
}
return cell;

运行看效果

4、关联xib与类文件（这个关联我经常弄错）
(到第3步,你已经可以看到自定义的cell了,但是还不能获取cell里面的信息,因为没有关联)
选中CellSearch.xib中的UITableViewCell控件，将类名关联为CellSearch
(然后就是Cell内普通的控件关联了)

5、使用
在cellForRowAtIndexPath 方法中使用
例如：
CellSearch *cell = [tableView dequeueReusableCellWithIdentifier:@”CellSearch”];
if(!cell) {
cell = [[[NSBundle mainBundle] loadNibNamed:@”CellSearch” owner:self options:nil]lastObject];
}
cell.nameTextField.text = @”tom”; //关联后可以直接设置cell内的控件
return cell;
第三种就是直接在
