等高Cell

一、自定义Cell
1、等高cell

很古老的方法：

#import "YJHTableViewCell.h"

@interface YJHTableViewCell()
@property (nonatomic, weak) UIImageView *iconImageView;
@property (nonatomic, weak) UILabel *titleLabel;
@property (nonatomic, weak) UILabel *priceLabel;
@property (nonatomic, weak) UILabel *buyCountLabel;

@end

@implementation YJHTableViewCell

// 这个方法添加所有控件,调用init、initWithFrame都会通过该方法
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
    if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
        
        UIImageView *iconImageView = [[UIImageView alloc] init];
        [self.contentView addSubview:iconImageView];
        self.iconImageView = iconImageView;
        self.iconImageView.backgroundColor = [UIColor greenColor];

        UILabel *titleLabel = [[UILabel alloc] init];
        [self.contentView addSubview:titleLabel];
        self.titleLabel = titleLabel;
        self.titleLabel.backgroundColor = [UIColor redColor];

        UILabel *priceLabel = [[UILabel alloc] init];
        [self.contentView addSubview:priceLabel];
        self.priceLabel = priceLabel;
        self.priceLabel.backgroundColor = [UIColor yellowColor];

        UILabel *buyCountLabel = [[UILabel alloc] init];
        [self.contentView addSubview:buyCountLabel];
        self.buyCountLabel = buyCountLabel;
        self.buyCountLabel.backgroundColor = [UIColor blueColor];

    }
    return self;
}
// 设置所有子控件的frame
- (void)layoutSubviews{
    [super layoutSubviews];
    CGFloat space = 10;
    CGFloat contentH = self.contentView.frame.size.height;
    CGFloat contentW = self.contentView.frame.size.width;

    
    CGFloat iconX = space;
    CGFloat iconY = space;
    CGFloat iconW = 80;
    CGFloat iconH = contentH - 2 * space;
    self.iconImageView.frame = CGRectMake(iconX, iconY, iconW, iconH);
    
    CGFloat titleX = CGRectGetMaxX(self.iconImageView.frame)+space;
    CGFloat titleY = iconY;
    CGFloat titleW = contentW - titleX - space;
    CGFloat titleH = 20;
    self.titleLabel.frame = CGRectMake(titleX, titleY, titleW, titleH);
    
    CGFloat priceX = iconX + iconW + space;
    CGFloat priceY = CGRectGetMaxY(self.iconImageView.frame) - 20;
    CGFloat priceW = 100;
    CGFloat priceH = 20;
    self.priceLabel.frame = CGRectMake(priceX, priceY, priceW, priceH);
    
    CGFloat buyCountX = contentW - space - 50;
    CGFloat buyCountY = CGRectGetMaxY(self.iconImageView.frame) - 20;
    CGFloat buyCountW = 50;
    CGFloat buyCountH = 20;
    self.buyCountLabel.frame = CGRectMake(buyCountX, buyCountY, buyCountW, buyCountH);
}
@end

利用autoLayout

• xib
  加载xib要通过手动加载：[[[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil] lastObject];
  下面是数据和界面的关系：

• storyboard
  和xib很像
