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];
}

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;
}
