uni.makePhoneCall的使用没有效果

刚测试了，没问题呀

uni.makePhoneCall({  
    phoneNumber: '114' //仅为示例  
});  

这玩意需要权限, 所以我选择

let makePhoneCall = function(phoneNum = '') {  
    return new Promise((succ, error) => {  
        if (uni.getSystemInfoSync().platform == "android") {  
            let main = plus.android.runtimeMainActivity();  
            let Intent = plus.android.importClass("android.content.Intent");  
            let intent = new Intent(Intent.ACTION_DIAL);  

            let Uri = plus.android.importClass("android.net.Uri");  
            let data = Uri.parse("tel:" + phoneNum);  

            intent.setData(data);  
            main.startActivity(intent);  
            succ({code: 0});  
        }else{  
            uni.makePhoneCall({  
              phoneNumber: phoneNum,  
              success: () => {  
                succ({code: 0});  
              },  
              fail() {  
                error({code: -1});  
              }  
            });  
        }  
    })  
}
