自定义cell

步骤:

创建MyTableViewCell类

//  自定义初始化
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];

if (self) {

[self addSubViews];

}

return self;

}

//  添加子视图
- (void)addSubViews{

self.imageV = [[UIImageView alloc] initWithFrame:CGRectMake(kMargin, kMargin, kImageWidth, kImageHeight)];

self.imageV.backgroundColor = [UIColor redColor];

[self.contentView addSubview:self.imageV];
[_imageV release];

self.nameLable = [[UILabel alloc] initWithFrame:CGRectMake(self.imageV.XWidth + kMargin, self.imageV.Y - 2.5, kScreenWidth - self.imageV.XWidth - 2 * kMargin, kImageHeight / 3  )];

self.nameLable.backgroundColor = [UIColor cyanColor];

[self.contentView addSubview:self.nameLable];

self.phoneLabel = [[UILabel alloc] initWithFrame:CGRectMake(self.nameLable.X, self.nameLable.YHeight + 5, kScreenWidth - self.imageV.XWidth - 2 * kMargin, kImageHeight / 3  )];

self.phoneLabel.backgroundColor = [UIColor cyanColor];

[self.contentView addSubview:self.phoneLabel];

self.genderLabel = [[UILabel alloc] initWithFrame:CGRectMake(self.phoneLabel.X, self.phoneLabel.YHeight + 5, kScreenWidth - self.imageV.XWidth - 2 *kMargin, kImageHeight / 3 )];

self.genderLabel.backgroundColor = [UIColor cyanColor];

[self.contentView addSubview:self.genderLabel];

}

封装以model类传值

在model类自定义的cell类中声明一个model类属性

@property (nonatomic, retain) Student *stuModel;
- (void)setStuModel:(Student *)stuModel;

重写model属性的set方法

//  重写model的set方法 使赋值model的同时也给控件赋值
- (void)setStuModel:(Student *)stuModel{

if (_stuModel != stuModel) {

[_stuModel release];

_stuModel = [stuModel retain];

}

self.nameLable.text = stuModel.name;
self.phoneLabel.text = stuModel.gender;
self.genderLabel.text = stuModel.phoneNumber;
self.imageV.image = [UIImage imageNamed:@"拔刀斋.jpg"];

}

返回cell

static NSString *identifier = @"MaleCell";
MaleTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

if (cell == nil) {

cell = [[[MaleTableViewCell alloc] initWithStyle:(UITableViewCellStyleSubtitle) reuseIdentifier:identifier] autorelease];
}
//  以model直接赋值
Student *stu = self.dataArray[indexPath.row];
cell.stuModel = stu;
return cell;

}
//在给model赋值时 也给cell的控件完成赋值

返回不同的cell

再创建一个自定义cell类

//  重写初始化方法
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{

self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];

if (self) {

[self addSubviews];

}

return self;

}

- (void)addSubviews{

self.nameLable = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width / 4, 40)];
self.nameLable.backgroundColor = [UIColor redColor];

[self.contentView addSubview:self.nameLable];

[_nameLable release];
}

//  重写model的set方法 使赋值model的同时也给控件赋值
- (void)setStuModel:(Student *)stuModel{

if (_stuModel != stuModel) {

[_stuModel release];

_stuModel = [stuModel retain];

}

self.nameLable.text = stuModel.name;

}

根据条件返回不同的cell

//  返回cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

Student *stu = self.dataArray[indexPath.row];

//  根据stuModel的值进行判断选用不一样的cell显示
if ([stu.gender isEqualToString:@"女"]) {

//  创建女的
static NSString *identifier = @"GirlCell";

MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

if (cell == nil) {

cell = [[[MyTableViewCell alloc] initWithStyle:(UITableViewCellStyleSubtitle) reuseIdentifier:identifier] autorelease];

}

cell.stuModel = stu;
return cell;

}else{

//  创建男的
static NSString *identifier = @"MaleCell";

MaleTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

if (cell == nil) {

cell = [[[MaleTableViewCell alloc] initWithStyle:(UITableViewCellStyleSubtitle) reuseIdentifier:identifier] autorelease];

}

cell.stuModel = stu;
return cell;

}

//  在给model赋值时 也给cell的控件完成赋值

}
