配置隱私協議 - iOS

根據蘋果隱私協議新規的推出,要求所有應用包含隱私保護協議,故為此在 App 中添加了如下隱私協議模塊.

首次安裝 App 的情況下默認調用隱私協議模塊展示相關信息一次,當用戶點擊同意按鈕后,從此不再執行該模塊方法.

具體 code 如下:

一.聲明(.h)

/*
 隱私協議
 */
#import <Foundation/Foundation.h>
 
@interface PrivacyAgreement : NSObject
 
+ (instancetype)shareInstance;
 
@end

 

二.實現(.m)

#import "PrivacyAgreement.h"
 
/** 獲取沙盒 Document 路徑*/
#define kDocumentPath       [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]
#define kKeyWindow          [UIApplication sharedApplication].keyWindow
 
#define SCREEN_WIDTH    ([UIScreen mainScreen].bounds.size.width)
#define SCREEN_HEIGHT   ([UIScreen mainScreen].bounds.size.height)
 
#define LocalName_ProjectConfig        @"ProjectConfigInfo.plist" // 本地存儲路徑設置_文件名稱
#define LocalPath_ProjectConfig        @"Project/ProjectConfigInfo/" // 本地存儲路徑設置_文件路徑
#define PrivacyAgreementState  @"PrivacyAgreementState"
 
@interface PrivacyAgreement () <WKNavigationDelegate, WKUIDelegate>
 
@property (nonatomic, strong) UIView *backgroundView;
@property (nonatomic, strong) UIButton *btnAgree;
@property (nonatomic, strong) WKWebView *webView;
 
@end
 
@implementation PrivacyAgreement
 
+ (instancetype)shareInstance {
    static PrivacyAgreement *instance = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        instance = [[PrivacyAgreement alloc] init];
    });
    
    return instance;
}
 
- (instancetype)init {
    self = [super init];
    if (self) {
        [[NSNotificationCenter defaultCenter] addObserverForName:UIApplicationDidFinishLaunchingNotification object:nil queue:nil usingBlock:^(NSNotification * _Nonnull note) {
            
            NSFileManager *fileManager = [NSFileManager defaultManager];
            if ([fileManager fileExistsAtPath:[kDocumentPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@%@", LocalPath_ProjectConfig, LocalName_ProjectConfig]]]) {
                NSMutableDictionary *configInfo = [NSMutableDictionary dictionaryWithContentsOfFile:[kDocumentPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@%@", LocalPath_ProjectConfig, LocalName_ProjectConfig]]];
                if ([[configInfo objectForKey:@"PrivacyAgreementState"] isEqualToString:@"PrivacyAgreementState"]) {} else {
                    // Show Privacy AgreementState View
                    [self showPrivacyAgreementStateView];
                }
            }
            else {
                // Show Privacy AgreementState View
                dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                    [self showPrivacyAgreementStateView];
                });
            }
        }];
    }
    
    return self;
}

    [_backgroundView removeFromSuperview];
}
 
 
 
@end

注:如上方法中使用的本地加載的方式,若需要使用網絡請求的方式,詳見具體 code 中的注釋部分.

 

三.方法調用

在需要的地方引用該頭文件並調用接口方法即可,一般在 appdelegate 中.

[PrivacyAgreement shareInstance];

 

四.方法類中相關封裝的方法

4.1.點擊事件中文件寫入本地的方法

/**
 插入對象至本地 plist 文件
 @param dataSource  數據源
 @param fileName    文件名稱
 @param filePath    文件路徑
 */
void InsertObjectToLocalPlistFile(NSMutableDictionary *dataSource, NSString *fileName, NSString *filePath) {
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString *docPath = [kDocumentPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@%@", filePath, fileName]];
    if ([fileManager fileExistsAtPath:docPath]) {// 文件存在
        NSLog(@"本地 plist 文件 --- 存在");
        [dataSource writeToFile:[[kDocumentPath stringByAppendingPathComponent:filePath] stringByAppendingPathComponent:fileName] atomically:YES];
    }
    else {// 文件不存在
        NSLog(@"本地 plist 文件 --- 不存在");
        CreateLocalPlistFile(dataSource, fileName, filePath);
    }
}
