为了增加代码的可读性和可维护性，我们今天准备拟一篇代码规范博客。
本博客分两部分来说：项目结构规范 以及 代码风格规范。
同时，这也是我们QiShare团队的代码规范~
如果觉得不错，大家也可以拿来借鉴一下。
一、项目结构：
整体结构：
主要模块结构：
子模块结构：
代码风格：
- 类扩展申明规范： 1.常量、静态变量声明在前 2.@property声明同一类别放在一起，不同类别换行写 3.包括空格规范，几个注意点如下代码示例：
static NSString *mineCellId = @"mineCellId";
@interface QiMineViewController () <UITableViewDataSource, UITableViewDelegate>
@property (nonatomic, strong) UIView *headView;
@property (nonatomic, strong) UITableView *tableView;
@property (nonatomic, copy) NSArray<QiMineData *> *cellDatas;
@end
- 方法编写规范：
- 前括号提至方法后
- 同一模块功能代码写在一起
- 不同模块功能换行写
- (void)viewDidLoad {
[super viewDidLoad];
[self setupHeadView];
[self setupTableView];
[self getCellDatas];
}
- 方法归类：
#pragma mark - Private Functions
//code...
//上空一行
//下空两行
#pragma mark - Action functions
//code...
//上空一行
//下空两行
#pragma mark - Request functions
//code...
//上空一行
//下空两行
#pragma mark - xxxDataSource
//code...
//上空一行
//下空两行
#pragma mark - xxxDelegate
//code...
//上空一行
//下空两行
以下是我写的一个简单的MVC结构 代码示例：
Model层：
- QiMineData.h
#import <Foundation/Foundation.h>
typedef NS_ENUM(NSUInteger, QiMineDataType) {
QiMineDataTypeDefault,//!< 默认类型
QiMineDataTypeOne,//!< 类型1
QiMineDataTypeTwo,//!< 类型2
};
@interface QiMineData : NSObject
@property (nonatomic, copy) NSString *title;//!< 标题文本
@property (nonatomic, copy) NSString *detail;//!< 细节文本
@property (nonatomic, assign) QiMineDataType type;//!< 数据类型
/**
@brief QiMineData初始化方法
@param dic 初始化数据源字典
@return QiMineData实例
*/
- (instancetype)initWithDic:(NSDictionary *)dic;
@end
- QiMineData.m
#import "QiMineData.h"
@implementation QiMineData
- (instancetype)initWithDic:(NSDictionary *)dic {
self = [super init];
if (self) {
_title = dic[@"title"];
_detail = dic[@"detail"];
}
return self;
}
@end
View层:
- QiMineCell.h
#import <UIKit/UIKit.h>
#import "QiMineData.h"
@interface QiMineCell : UITableViewCell
@property (nonatomic, strong) QiMineData *cellData;//!< cell的数据model实例
@end
- QiMineCell.m
#import "QiMineCell.h"
@interface QiMineCell()
@property (nonatomic, strong) UIImageView *iconView;
@property (nonatomic, strong) UILabel *titleLabel;
@property (nonatomic, strong) UILabel *detailLabel;
@end
@implementation QiMineCell
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
_iconView = [[UIImageView alloc] initWithFrame:CGRectZero];
[self.contentView addSubview:_iconView];
_titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
_titleLabel.font = [UIFont systemFontOfSize:16.0];
_titleLabel.textColor = [UIColor blackColor];
[self.contentView addSubview:_titleLabel];
_detailLabel = [[UILabel alloc] initWithFrame:CGRectZero];
_detailLabel.font = [UIFont systemFontOfSize:14.0];
_detailLabel.textColor = [UIColor grayColor];
[self.contentView addSubview:_detailLabel];
}
return self;
}
- (void)layoutSubviews {
[super layoutSubviews];
CGFloat margin = 10.0;
CGFloat padding = 10.0;
CGFloat MaxHeight = self.contentView.frame.size.height;
CGFloat MaxWidth = self.contentView.frame.size.width;
_iconView.frame = CGRectMake(margin, margin, 35.0, 35.0);
_iconView.layer.cornerRadius = _iconView.frame.size.width / 2;
_iconView.layer.masksToBounds = YES;
_titleLabel.frame = CGRectMake(_iconView.frame.origin.x + _iconView.frame.size.width + padding, .0, 60.0, MaxHeight);
_detailLabel.frame = CGRectMake(_titleLabel.frame.origin.x + _titleLabel.frame.size.width + padding, MaxHeight * 0.5, MaxWidth - _titleLabel.frame.size.width - padding * 2 - margin *2, MaxHeight * 0.5);
}
-(void)setCellData:(QiMineData *)cellData {
_cellData = cellData;
_iconView.image = [UIImage imageNamed:@"qishare"];
_titleLabel.text = cellData.title;
_detailLabel.text = cellData.detail;
}
