篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了配置隐私协议 - iOS相关的知识,希望对你有一定的参考价值。

根据苹果隐私协议新规的推出,要求所有应用包含隐私保护协议,故为此在 App 中添加了如下隐私协议模块.

首次安装 App 的情况下默认调用隐私协议模块展示相关信息一次,当用户点击同意按钮后,从此不再执行该模块方法.

具体 code 如下:

一.声明(.h)

/*
 隐私协议
 */
#import <Foundation/Foundation.h>
 
@interface PrivacyAgreement : NSObject
 
+ (instancetype)shareInstance;
 
@end

 

二.实现(.m)

#import "PrivacyAgreement.h"
 
/** 获取沙盒 Document 路径*/
#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" // 本地存储路径设置_文件名称
#define LocalPath_ProjectConfig        @"Project/ProjectConfigInfo/" // 本地存储路径设置_文件路径
#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;
}
 
 
 
/**
 渲染隐私协议视图
 */
- (void)showPrivacyAgreementStateView {
    [kKeyWindow addSubview:self.backgroundView];
    [self webView];
    [self.backgroundView addSubview:self.btnAgree];
}
 
 
 
#pragma mark - ************************************************ UI
- (UIView *)backgroundView {
    if (!_backgroundView) {
        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];
        view.backgroundColor = [UIColor whiteColor];
        view.userInteractionEnabled = YES;
        
        _backgroundView = view;
    }
    return _backgroundView;
}
 
/**

 @return 当前控件
 */
- (WKWebView *)webView {
    if (!_webView) {
        NSError *error;
        // 本地 url 地址设置
        NSURL *URLBase = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
        NSString *URLAgreement = [[NSBundle mainBundle] pathForResource:@"agreement" ofType:@"html"];
        NSString *html = [NSString stringWithContentsOfFile:URLAgreement
                                                   encoding:NSUTF8StringEncoding
                                                      error:&error];
        
        WKWebViewConfiguration *webConfig = [[WKWebViewConfiguration alloc] init];
        webConfig.preferences = [[WKPreferences alloc] init];
        webConfig.preferences.javascriptEnabled = YES;
        webConfig.preferences.javaScriptCanOpenWindowsAutomatically = NO;
        
        WKWebView *webView = [[WKWebView alloc] initWithFrame:CGRectMake(10, 70, SCREEN_WIDTH - 20, SCREEN_HEIGHT - 150)
                                                configuration:webConfig];
        webView.navigationDelegate = self;
        webView.UIDelegate = self;
#pragma mark - 本地 html 文件加载方式
        [webView loadHTMLString:html baseURL:URLBase];
#pragma mark - 网络请求加载方式
//        NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@""]// 隐私协议的 url 地址
//                                                 cachePolicy:NSURLRequestReloadIgnoringCacheData
//                                             timeoutInterval:3.0];
//        [webView loadRequest:request];
        
        [_backgroundView addSubview:webView];
        
        _webView = webView;
    }
    return _webView;
}
 
- (UIButton *)btnAgree {
    if (!_btnAgree) {
        UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
        btn.frame = CGRectMake(CGRectGetMidX(_webView.frame) - 50, CGRectGetMaxY(_webView.frame) + 10, 100, 44);
        btn.backgroundColor = [UIColor whiteColor];
        [btn setTitle:@"同意" forState:UIControlStateNormal];
        [btn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
        [btn addTarget:self action:@selector(btnClick) forControlEvents:UIControlEventTouchUpInside];
        
        _btnAgree = btn;
    }
    return _btnAgree;
}
 
- (void)btnClick {
    NSMutableDictionary *configInfo = [NSMutableDictionary dictionaryWithContentsOfFile:[kDocumentPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@%@", LocalPath_ProjectConfig, LocalName_ProjectConfig]]];
    [configInfo setValue:PrivacyAgreementState forKey:@"PrivacyAgreementState"];
    InsertObjectToLocalPlistFile(configInfo, LocalName_ProjectConfig, LocalPath_ProjectConfig);
    [_backgroundView removeFromSuperview];
}
 
 
 
@end

注:如上方法中使用的本地加载的方式,若需要使用网络请求的方式,详见具体 code 中的注释部分.

 

三.方法调用

在需要的地方引用该头文件并调用接口方法即可,一般在 appdelegate 中.

[PrivacyAgreement shareInstance];

 

四.方法类中相关封装的方法

4.1.点击事件中文件写入本地的方法

/**
 插入对象至本地 plist 文件
 @param dataSource  数据源
 @param fileName    文件名称
 @param filePath    文件路径
 */
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);
    }
}
