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;
} /**
WebView 设置相关 其中包含加载方式(本地文件 & 网络请求)
@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);
}
}
以上便是此次分享的内容,还望能对大家有所帮助,谢谢!
