现在app在ios9运行出现了这些，查了下资料。
根据网上的做法。

iOS9 URL Schemes 

除了要在项目info URL Types中设置URL Schemes，还需要在info.plist里面增加可信任的调用app，否则回报如下错误

-canOpenURL: failed for URL: "weixin://app/wx9c8771d3c07dfd30/" - error: "This app is not allowed to query for scheme weixin"

-canOpenURL: failed for URL: "wtloginmqq2://qzapp" - error: "This app is not allowed to query for scheme wtloginmqq2"

info.plist加入

<key>LSApplicationQueriesSchemes</key>

<array>

<string>urlscheme</string>

<string>urlscheme2</string>

<string>urlscheme3</string>

<string>urlscheme4</string>

</array>

我加入之后。

本来加入之前提示：
-canOpenURL: failed for URL: "mqqopensdkapiV2://qzapp" - error: "This app is not allowed to query for scheme mqqopensdkapiV2"

加入之后，error原因就没有了。如下：

-canOpenURL: failed for URL: "mqqopensdkapiV2://qzapp" - error: "(null)"

可是仍然是fail的。不知道如何解决？

Answer 1

You need to use a real device with iOS9! Do not use the simulator to test, otherwise it will keep reporting -canOpenURL: failed for URL: "XXXXXXXXXX" - error: "(null)". My real machine test passed.

Answer 2

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>mqqOpensdkSSoLogin</string>
    <string>mqzone</string>
    <string>sinaweibo</string>
    <string>alipayauth</string>
    <string>alipay</string>
    <string>safepay</string>
    <string>mqq</string>
    <string>mqqapi</string>
    <string>mqqopensdkapiV3</string>
    <string>mqqopensdkapiV2</string>
    <string>mqqapiwallet</string>
    <string>mqqwpa</string>
    <string>mqqbrowser</string>
    <string>wtloginmqq2</string>
    <string>weixin</string>
    <string>wechat</string>
</array>加了15条 才实现

qq login binding, qq payment, qq sharing
WeChat payment, WeChat login binding
Sina login binding
Alipay payment, Alipay login binding

Answer 3

The best way is to read the official documentation directly

1. Support http protocol

(1) Temporarily fall back to http protocol info plist added

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

(2) Add the specified domain name to the http whitelist

2 Involves client jump setting scheme to LSApplicationQueriesSchemes

Summary: For problems like this, if you use a third party, just look at other people’s official websites. Otherwise, visit the providers’ official APIs such as WeChat, QQ, and Alipay to read the development documents.
If you use sharesdk, Umeng, etc., go to their development documents. We will provide solutions to developers as soon as possible

sharesdk shares the iOS9 adaptation document address

Umeng shares iOS9 adaptation address

If you are paying for other logins, you can also go to their official development documents and have a look

The iOS FAQ community will answer your questions

If you have any questions, you can ask directly in the group

Answer 4

Solved,
share to qq, you need to add

To share on WeChat, you need to add:

Answer 5

Have you found the answer? I added it but still got an error of null

Answer 6

Will the error continue to occur even after adding it? That url scheme

Answer 7

I added it, but it still keeps reporting errors about that url scheme. Does anyone know how to solve it?

Answer 8

There is a bug in this simulator. If you use a real device with iOS 9, you can avoid this problem. It is estimated that Xcode will fix it in subsequent upgrades.

Test URL Scheme. Try to avoid using simulator to test, otherwise it will always report

-canOpenURL: failed for URL: "XXXXXXXXXX" - error: "(null)"。

Personally tested on a real device and passed.

Answer 9

-canOpenURL: failed for URL: "mqzone://sdk" - error: "(null)" On the real machine, this will still be reported, and <string>mqzone</string> has been added. And just restart the app, once TecentOAuth is called

(void)logout:(id<TencentSessionDelegate>)delegate;
This method will report the error just now if you execute login authorization again.

I have deleted this sentence now. When logging out, just clear the TecentOAuth accessToken and it will be fine

Answer 10

If your application uses functions such as SSO authorized login or jump sharing, you need to add a jumpable whitelist under iOS9 and specify the URL Scheme corresponding to the jump App. Otherwise, the third-party platform will determine whether to jump. When using canOpenURL, NO is returned, and then only webview authorization or authorization/sharing fails.
