前言

熟悉监管要求，掌握合规操作流程，避免App被降级或者下架。

需要确保App有《隐私政策》，并且在用户首次启动App时就弹出《隐私政策》取得用户同意。

登录界面弹用户协议及隐私政策时，如果用户点击不同意，不能停留在弹框界面，需要隐藏弹框，否则无法通过OPPO安卓应用市场。

《用户协议及隐私政策》弹框的实现步骤:

1、自定义TextView，采用富文本属性进行内容设置attributedText（包括下划线NSUnderlineStyleSingle、超链接NSLinkAttributeName 、颜色NSForegroundColorAttributeName 等信息） 2、实现代理方法textView:shouldInteractWithURL:inRange，处理点击超链接的回调（打开对应URL Webview）

效果图（点击demo的右上架文字进行中英文切换）

文本框信息对应的中英文key,用于本地化

"Explain3" = "向您说明，在使用我们的服务时，我们如何收集、使用、储存和分享这些信息，以及我们为您提供的访问、更新、控制和保护这些信息的方式。本";
"Wemaycollect1"="您在使用我们的服务时，我们可能会收集和使用您的相关信息。我们希望通过本";
"then_click_Agree" = " ，希望您仔细阅读，充分理解协议中的内容后再点击同意。";


"Wemaycollect1"="We may collect and use information about you when you use our services. We hope to pass this";
"Explain3"= "Explain to you how we collect, use, store and share this information and how we provide you with access, update, control and protection when using our services. this";
"then_click_Agree"= "  , I hope you read it carefully, fully understand the content of the agreement, and then click Agree.";

I、自定义TextView： QCTTextViewHyperLink

demo源码：存放在GitHub私有仓库 demo源码

1.1 采用富文本属性进行内容设置

attributedText

包括下划线NSUnderlineStyleSingle、超链接NSLinkAttributeName 、颜色NSForegroundColorAttributeName 等信息

新增超链接属性

[attrStr addAttribute:NSLinkAttributeName value:k_serviceAgreement_URL range:str4Range];

        [attrStr addAttribute:NSLinkAttributeName value:k_serviceAgreement_URL range:str2Range];

        tmp.editable = NO;
        tmp.attributedText = attrStr;//text
            tmp.selectedRange = NSMakeRange(attrStr.length, 0);


        tmp.delegate = self;
        tmp.userInteractionEnabled = YES;

设置下划线和颜色

[attrStr setAttributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle)}
                     range:str4Range];
    [attrStr addAttribute:NSFontAttributeName value:kPingFangFont(13) range:str4Range];


    [attrStr addAttribute:NSForegroundColorAttributeName value:HWColor(6, 53, 253) range:str4Range];

1.2 实现代理方法

处理点击超链接的回调（打开对应URL Webview）

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {

/**
 代理方法
 */
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {

    __weak __typeof__(self) weakSelf = self;

    if([URL.absoluteString isEqualToString:k_serviceAgreement_URL]){

        [self.viewModel.hiddenQCTserviceAgreementViewSubject sendNext:nil];

        void (^showQCTserviceAgreementViewBlock)(id sender) = ^void(id sender) {
            NSLog(@"nil");
            // 展示
            [weakSelf.viewModel.showQCTserviceAgreementViewSubject sendNext:nil];


        };
                                        [self.viewModel.User_Agreement_and_Privacy_PolicySubject sendNext:showQCTserviceAgreementViewBlock];

    }

//


    return NO;
}

II、封装《用户协议及隐私政策》视图

获取带有富文本字符串的TextView视图

#import "QCTTextViewHyperLink.h"

@implementation QCTTextViewHyperLink

/**
 获取 《用户协议及隐私政策》的数据
 @return《用户协议及隐私政策》的数据
 */
+ (instancetype)getserviceAgreemenTextView{

    QCTTextViewHyperLink * tmp  = [QCTTextViewHyperLink new];
    NSString *str1 = QCTLocal(@"Wemaycollect1");
    NSString *str2 = [NSString stringWithFormat:@"《%@》",QCTLocal(@"Service_Agreement4User")];

    NSString *str3 = QCTLocal(@"Explain3");
    NSString *str4 = [NSString stringWithFormat:@"《%@》",QCTLocal(@"Service_Agreement4User")];

    NSString *str5 = QCTLocal(@"then_click_Agree");
    NSString *str = [NSString stringWithFormat:@"%@%@%@%@%@",str1,str2,str3,str4,str5];

    //1、 设置富文本属性
    NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:str];

    [attrStr addAttribute:NSFontAttributeName value:kPingFangFont(13) range:NSMakeRange(0 ,attrStr.length)];

    [attrStr addAttribute:NSForegroundColorAttributeName value:HWColor(51, 51, 51) range:NSMakeRange(0 ,attrStr.length)];


// 2、设置行lineSpacing
    NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
    paragraphStyle.lineSpacing = 5;
    NSMutableDictionary *attributes = [NSMutableDictionary dictionary];
    [attributes setObject:paragraphStyle forKey:NSParagraphStyleAttributeName];
    [attrStr addAttributes:attributes range:NSMakeRange(0, attrStr.length)];

    //        NSParagraphStyle defaultParagraphStyle
//3、设置下划线和颜色
    NSRange str2Range = NSMakeRange(str1.length, str2.length );

    NSRange str4Range = NSMakeRange(str1.length+str2.length+str3.length, str4.length );


    [attrStr setAttributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle)}
                     range:str2Range];
    [attrStr addAttribute:NSFontAttributeName value:kPingFangFont(13) range:str2Range];

    [attrStr addAttribute:NSForegroundColorAttributeName value:HWColor(6, 53, 253) range:str2Range];


    [attrStr setAttributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle)}
                     range:str4Range];
    [attrStr addAttribute:NSFontAttributeName value:kPingFangFont(13) range:str4Range];

    [attrStr addAttribute:NSForegroundColorAttributeName value:HWColor(6, 53, 253) range:str4Range];


    //4、新增超链接属性
    [attrStr addAttribute:NSLinkAttributeName value:k_serviceAgreement_URL range:str4Range];

    [attrStr addAttribute:NSLinkAttributeName value:k_serviceAgreement_URL range:str2Range];

    tmp.editable = NO;
    tmp.attributedText = attrStr;//text
    tmp.selectedRange = NSMakeRange(attrStr.length, 0);
    //        tmp.userInteractionEnabled = YES;


    return tmp;
}

// 继承UITextView重写这个方法
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
    // 返回NO为禁用，YES为开启
    // 粘贴
    if (action == @selector(paste:)) return NO;
    // 剪切
    if (action == @selector(cut:)) return NO;
    // 复制
    if (action == @selector(copy:)) return NO;
    // 选择
    if (action == @selector(select:)) return NO;
    // 选中全部
    if (action == @selector(selectAll:)) return NO;
    // 删除
    if (action == @selector(delete:)) return NO;
    // 分享
    if (action == @selector(share)) return NO;
    return [super canPerformAction:action withSender:sender];

}
