iOS代码规范

1.网络层：
@interface WM_NetworkManager : AFHTTPSessionManager

单例：+(WM_NetworkManager *)shareInstance
{
static WM_NetworkManager * shareInstance;
static dispatch_once_t onceToken;
dispatch_once(&onceToken,^{
shareInstance = [[self alloc] init];
});
return shareInstance;
}

• (instancetype)init
  {
  if (self = [super init]) {
  [self Reachability];
  [self setSessionManagerParameter];
  }
  return self;
  }

pragma mark -- 网络监听

• (void)Reachability
  {
  [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
  //debugLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
  }];

  [[AFNetworkReachabilityManager sharedManager] startMonitoring];
  }
  AFHTTPSessionManager：

• (void)setSessionManagerParameter
  {
  //设置请求头参数
  _sessionManager = [AFHTTPSessionManager manager];
  _sessionManager.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
  _sessionManager.requestSerializer.timeoutInterval = 20;
  _sessionManager.requestSerializer = [AFHTTPRequestSerializer serializer];
  _sessionManager.responseSerializer = [AFJSONResponseSerializer serializer];
  [_sessionManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
  }
  实例方法：

pragma mark 数据请求封装

-(void)postPath:(NSString *)path parameters:(NSDictionary *)parameters withBlock:(void (^)(NSDictionary *, NSError *))block
{

NSString * url = [[WM_Single defaultSingle].APIHOST stringByAppendingString:path];

// NSString * url = @"http://192.168.2.165:8888/WebMobile.asmx/GetDepartByUserId";
[_sessionManager POST:url parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
debugLog(@"成功");
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (block) {
//NSLog(@"responseObject:%@",responseObject);
if (![[responseObject objectForKey:@"msg"] isEqualToString:@"ok"]) {
NSError *error = [NSError errorWithDomain:@"Message" code:[[responseObject objectForKey:@"ErrCode"] intValue] userInfo:[NSDictionary dictionaryWithDictionary:responseObject]];
block(nil,error);
// debugLog(@"%@", responseObject);
}else{
// NSString * str = [[WM_NetworkManager shareInstance] dictionaryToJson:responseObject];
block(responseObject,nil);
debugLog(@"请求成功");
// debugLog(@"responseObject11:%@", responseObject);
}
}
debugLog(@"%@", task);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
debugLog(@"%@", task);
debugLog(@"%@", error);
block(nil,error);

}];

}
//词典转换为字符串

• (NSString*)dictionaryToJson:(NSDictionary *)dic
  {

  NSError *parseError = nil;

  NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dic options:NSJSONWritingPrettyPrinted error:&parseError];

  return [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

}

pragma mark - 将解析的数据转化成字典

-(NSMutableDictionary *)dictionaryWithJsonString:(NSString *)jsonString
{
if (jsonString == nil) {
return nil;
}
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *err;
NSMutableDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&err];
if (err) {
NSLog(@"解析失败");
return nil;
}
return dic;
}
//将解析的数据转化成数组
-(NSMutableArray *)arrayWithJsonString:(NSString *)jsonString
{
if (jsonString == nil) {
return nil;
}
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *err;
NSMutableArray *array = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&err];
if (err) {
NSLog(@"解析失败");
return nil;
}
return array;
}
2.网络层第二层：类方法
//根据登录人获得其有权限的仓库

• (void)getDepartWithBlock:(void(^)(NSDictionary * result, NSError * error))block
  {
  NSString *userId = [[WM_Single defaultSingle] getTheValueOfUserName];
  NSDictionary * params = @{@"userId" : userId};
  [[WM_NetworkManager shareInstance] postPath:GetDepartURL parameters:params withBlock:block];
  }
  3.单例：保存到本地：
• (WM_Single *)defaultSingle
  {
  static WM_Single * single;
  if (!single) {
  single = [[WM_Single alloc] init];
  }
  return single;
  }
  //将用户名存入本地

• (void)setValueWithUserName:(NSString *)userName
  {
  NSUserDefaults * ud = [NSUserDefaults standardUserDefaults];
  [ud setValue:userName forKey:@"userName"];
  [ud synchronize];
  }
  //从本地取得用户名

• (NSString *)getTheValueOfUserName
  {
  NSUserDefaults * ud = [NSUserDefaults standardUserDefaults];
  return [ud stringForKey:@"userName"];
  }
  4.属性懒加载：
  -(NSMutableArray *)comNameArray{
  if (!_comNameArray) {
  _comNameArray = [[NSMutableArray alloc]init];
  }
  return _comNameArray;
  }
  5.自动登录：记住密码
  6.找回密码功能
  7.用户配置功能：
  if ([[WM_Single defaultSingle]getTheValueOfAPI] == nil) {

        _textField.text = @"http://192.168.2.165:8888/WebMobile.asmx/";
    }else{
    
        _textField.text = [[WM_Single defaultSingle]getTheValueOfAPI];
    }
  

8.请求加载：
UIWindow* window = [UIApplication sharedApplication].keyWindow;
__weak MBProgressHUD *hud = [ShowMessage showLoadingData:window];
[hud hide:YES];
9.判断手机是否联网：
//判断手机是否联网
AFNetworkReachabilityManager *managerAF = [AFNetworkReachabilityManager sharedManager];
[managerAF startMonitoring];
[managerAF setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

  switch (status) {
      case AFNetworkReachabilityStatusUnknown:
          [ShowMessage showTextOnly:@"暂时没有网络,登录时请检查网络" messageView:self.view];
          wangluo = false;
          break;
          
      case AFNetworkReachabilityStatusNotReachable:
          
          [ShowMessage showTextOnly:@"暂时没有网络,登录时请检查网络" messageView:self.view];
          wangluo = false;
          break;
          
      default:
          wangluo = true;
          break;
  }

}];
10.点击view缩放键盘:

• (void)tapView{

  UITapGestureRecognizer tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];
  tap1.cancelsTouchesInView = NO;
  [self.view addGestureRecognizer:tap1];
  }
  -(void)viewTapped:(UITapGestureRecognizer)tap1
  {
  [self.view endEditing:YES];
  }

11. 加载启动图片：在ViewController的viewDidLoad中
    if ([[WM_Single defaultSingle]getTheValueOfUserName]) {

    self.password.text = [[WM_Single defaultSingle]getTheValueOfPassword];
    self.userName.text = [[WM_Single defaultSingle]getTheValueOfUserName];
    self.OrganizeStructureTf.text = [[WM_Single defaultSingle]getValueOfComName];
    [WM_Single defaultSingle].APIHOST = @"http://192.168.2.165:8888/WebMobile.asmx/";
    
    UIImageView *startImage = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT)];
    _startImage = startImage;
    startImage.image = [UIImage imageNamed:@"云仓储启动页"];
    
    [self.view addSubview:startImage];
    [self LoginClick:nil];
    

    }
    11.设置占位符颜色：
    self.userName.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"请输入用户名" attributes:@{NSForegroundColorAttributeName:[UIColor lightGrayColor],NSFontAttributeName:[UIFont systemFontOfSize:16]}];
    12.输入框的监听来判断登录按钮的监听事件：
    //创建通知
    NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
    _center = center;
    //注册通知
    [center addObserver:self selector:@selector(textValueChanged) name:UITextFieldTextDidChangeNotification object:self.userName];
    [center addObserver:self selector:@selector(textValueChanged) name:UITextFieldTextDidChangeNotification object:self.password];
    [center addObserver:self selector:@selector(textValueChanged) name:UITextFieldTextDidChangeNotification object:self.OrganizeStructureTf];

• (void)textValueChanged
  {
  LoginButton.enabled = ((self.userName.text.length != 0) && (self.password.text.length != 0) && (self.OrganizeStructureTf.text.length != 0));
  if (LoginButton.enabled) {
  [LoginButton setImage:[UIImage imageNamed:@"登录1"] forState:UIControlStateNormal];
  }else{
  [LoginButton setImage:[UIImage imageNamed:@"登录2"] forState:UIControlStateNormal];
  }
  }
  千万一处通知：
  //移除通知
• (void)dealloc
  {
  [[NSNotificationCenter defaultCenter] removeObserver:self];
  }
  13.下拉框实现
  14.cellForRowAtIndexPath：

import "Masonry/Masonry.h"

//一些操作在cell中进行
PopupViewCell *cell = [PopupViewCell popupViewCellWithTableView:tableView];
cell.iconView.image = self.iconArray[indexPath.row];
cell.titleLable.text = self.textArray[indexPath.row];
//cell分割线
if (indexPath.row == self.textArray.count - 1) {
cell.haveSeparatorLine = YES;
}else{
cell.haveSeparatorLine = NO;
}
----------------cell-------------属性---------------

• (instancetype)popupViewCellWithTableView:(UITableView *)tableView;

@property (nonatomic, strong) UIImageView *iconView;
@property (nonatomic, strong) UILabel *titleLable;

@property (nonatomic, assign, getter=isHaveSeparatorLine) BOOL haveSeparatorLine; //是否有分割线
----------------cell---------------------------------

• (instancetype)popupViewCellWithTableView:(UITableView *)tableView {

  static NSString *cellID = @"PopupViewCell";

  PopupViewCell * cell = [tableView dequeueReusableCellWithIdentifier:cellID];

  if (!cell) {
  cell = [[PopupViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
  }
  return cell;
  }

• (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{

  if ( self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
  self.selectionStyle = UITableViewCellSelectionStyleNone;

    self.iconView = [[UIImageView alloc] init];
    [self.contentView addSubview:self.iconView];
    
    self.titleLable = [[UILabel alloc] init];
    self.titleLable.textColor = [UIColor blackColor];
    self.titleLable.font = [UIFont systemFontOfSize:14];
    [self.contentView addSubview:self.titleLable];
    
    //添加分割线
    self.separatorLineView = [[UIImageView alloc] init];
    self.separatorLineView.backgroundColor = [UIColor grayColor];
    [self.contentView addSubview:self.separatorLineView];
  

// self.separatorLineView.hidden = YES;
}
return self;
}

• (void)layoutSubviews{

  [super layoutSubviews];

  [self.iconView mas_makeConstraints:^(MASConstraintMaker *make) {
  make.leading.equalTo(self.contentView).offset(padding);
  make.centerY.equalTo(self.contentView);
  make.width.equalTo(@(0));
  make.height.equalTo(@(0));
  }];

  [self.titleLable mas_makeConstraints:^(MASConstraintMaker *make) {
  make.leading.equalTo(self.iconView.mas_trailing).offset(padding);
  make.centerY.equalTo(self.contentView);
  make.trailing.equalTo(self.contentView).offset(-padding);
  make.bottom.equalTo(self.contentView);
  }];

  [self.separatorLineView mas_makeConstraints:^(MASConstraintMaker *make) {
  make.leading.equalTo(self.textLabel);
  make.trailing.equalTo(self.contentView);
  make.bottom.equalTo(self.contentView.mas_bottom);
  make.height.equalTo(@(1 / ([UIScreen mainScreen].scale)));
  }];
  }

-(void)setHaveSeparatorLine:(BOOL)haveSeparatorLine{
_haveSeparatorLine = haveSeparatorLine;
self.separatorLineView.hidden = haveSeparatorLine;
}
