A short code can achieve a variety of commonly used functions, according to the data processing, file management, multimedia management, rights management, information system, Appstore, encryption and decryption, quick macro definition type package several different Category.

一、导入项目 Import project


The HDCommonTools can be imported with cocoapods or by downloading source files.

通过cocoapods导入 Importing through cocoapods

pod 'HDCommonTools'

通过文件导入 Importing through files


Download the project, import the contents of the HDCommonTools folder into the project.

二、函数使用 Function use


All function functions can be called in the two step.

1、导入头文件 Import header file

#import "HDCommonHeader.h"

2、通过单例调用即可 Can be called by a single case

[[HDCommonTools sharedHDCommonTools] getIOSLanguage];
[[HDCommonTools sharedHDCommonTools] getGPSLibraryWithType:kHDGPSPermissionWhenInUse];

3、权限通知说明 Permission notice


In the process of applying for permissions, a notification is triggered when the result is returned.

//System authority authorization change notification
FOUNDATION_EXPORT NSString * const HDPermissionStatusDidChangeNotification;

//The key of the userinfo in the system change notification, marked name
FOUNDATION_EXPORT NSString * const HDPermissionNameItem;

//The key of userinfo in the system change notification, marked state
FOUNDATION_EXPORT NSString * const HDPermissionStatusItem;


Take the application of GPS authority as an example

- (void)viewDidLoad {
    [super viewDidLoad];
    ///注册权限回调通知 egistration authority callback notice
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(permissionNotifacation:) name:HDPermissionStatusDidChangeNotification object:nil];
    ///申请gps权限 access to GPS
    [[HDCommonTools sharedHDCommonTools] getGPSLibraryWithType:kHDGPSPermissionWhenInUse];

    NSDictionary * userInfo = [notification userInfo];
    if ([[userInfo objectForKey:HDPermissionNameItem] integerValue] == kHDPermissionNameGPS) {
       if ([[userInfo objectForKey:HDPermissionStatusItem] integerValue] == kHDAuthorized) {
            NSLog(@"用户允许访问gps Users are allowed access to GPS");
        }else if ([[userInfo objectForKey:HDPermissionStatusItem] integerValue] == kHDAuthorRestricted){
            NSLog(@"用户被限制访问gps Users are restricted to access to GPS");
        }else if ([[userInfo objectForKey:HDPermissionStatusItem] integerValue] == kHDNotDetermined){
            NSLog(@"用户尚未选择是否允许访问gps User has not chosen to allow access to the GPS");
            NSLog(@"用户不允许访问gps Users do not allow access to GPS");


For clearer use, demo is perfected, and every usage in demo is used.


三、文件结构 file structure

文件名 file name文件作用 Document function
HDCommonHeader.h包含所有头文件 Contain all the header files
HDCommonDefine.h快捷处理的宏定义 Macro definition of shortcut processing
HDCommonToolsConfig项目定义的枚举类型 Enumerated type of project definition
HDCommonTools数据处理函数 Data processing function
