iOS 通過(guò)webview打開相冊(cè)和相機(jī), 地理位置信息

1,iOS通過(guò)webview 打開相機(jī)和相冊(cè)
1.1前端在webview里面的代碼
1.2 iOS 需要做的事情就是配置權(quán)限
1.2.1 配置info.plist 配置相機(jī),相冊(cè)和麥克風(fēng)的權(quán)限

Privacy - Camera Usage Description: 相機(jī)權(quán)限描述
Privacy - Photo Library Usage Description:相冊(cè)權(quán)限描述 
Privacy - Microphone Usage Description:麥克風(fēng)權(quán)限

2. iOS通過(guò)WebView獲取地理位置信息

2.1 前端在WebView里面獲取地理位置的代碼
2.2 iOS需要在info.plist配置地理位置權(quán)限, 獲取權(quán)限后h5即可獲得權(quán)限

  Privacy - Location Usage Description:地理位置權(quán)限描述

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
    NSLog(@"decidePolicyForNavigationAction");
    NSURLRequest * request = navigationAction.request;
    NSString * scheme = request.URL.scheme;
    // 處理通過(guò)webview 打電話邏輯
    if (scheme != nil && [@"tel" isEqualToString:scheme]) {
        [self hideLoadHud];
        UIApplication * app = [UIApplication sharedApplication];
        if ([app canOpenURL:request.URL]) {
            [app openURL:request.URL];
        }
        decisionHandler(WKNavigationActionPolicyCancel);
        return;
    }
    // 其他邏輯 ......
    
}

Android調(diào)用系統(tǒng)相機(jī)、GPS

相機(jī)調(diào)用準(zhǔn)備工作
聲明權(quán)限:

    <uses-permission android:name="android.permission.CAMERA" />
使用前動(dòng)態(tài)申請(qǐng)相機(jī)權(quán)限。
Android7.0以上需要 聲明FileProvider （http://www.itdecent.cn/p/47fcd7873f39）

相機(jī)調(diào)用開始

    val CAPTURE_REQUEST = 123

    fun file2Uri(file: File): Uri {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            val authority = application.packageName + ".provider"
            return FileProvider.getUriForFile(Utils.getApp(), authority, file)
