+
+## Can't receive response  after upgrading to 1.0.0 on iOS
+
+There's no need to override `AppDelegate` since `fluwx 1.0.0`. If you have did thad before, please remove 
+the following code in your `AppDelegate`:
+
+```objective-c
+
+- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

+
+If you have to override these two functions,make sure you have called the `super`:

+
+## 常见Q&A
+
+#### Fluwx调起失败？
+请检查APPID、包名、以及App签名是否一致。debug 和release的签名默认不一样，请注意。
+
+#### Android Flutter编译失败
+1、检查Kotlin版本，打开```build.gradle```文件，查看以下配置
+```
+buildscript {
+	······
+	ext.kotlin_version = '1.3.11'
+	······
+}
+```
+确保项目中使用的Kotlin版本符合要求；
+2、检查Android目录下```build.gradle```文件中gradle插件版本：```classpath 'com.android.tools.build:gradle:3.2.1'```和```gradle-wrapper.properties```文件中的gradle版本是否匹配：```distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip```，两者的匹配规则见Android官网：[Update Gradle](https://developer.android.com/studio/releases/gradle-plugin.html#updating-gradle)
+
+#### WeChat Not Installed on iOS?
+iOS 9系统策略更新，限制了http协议的访问，此外应用需要在“Info.plist”中将要使用的URL Schemes列为白名单，才可正常检查其他应用是否安装。
+受此影响，当你的应用在iOS 9中需要使用微信SDK的相关能力（分享、收藏、支付、登录等）时，需要在“Info.plist”里增加如下代码：
+```xml
+<key>LSApplicationQueriesSchemes</key>
+<array>
+<string>weixin</string>
+</array>
+<key>NSAppTransportSecurity</key>
+<dict>
+<key>NSAllowsArbitraryLoads</key>
+<true/>
+</dict>
+```
+
+#### 如果没有安装微信，微信登录不了，导致iOS审核失败
+fluwx提供了检查用户是否安装微信的方法：```isWeChatInstalled()```，iOS使用微信相关功能前，务必先检查微信是否安装。
+
+#### Failed to notify project evalution listener
+[Failed to notify project evalution listener](https://www.jianshu.com/p/f74fed94be96)
+
+#### 微信登录不能触发fluwx.responseFromAuth.listen监听回调
+请先看文档：[微信调回](https://github.com/OpenFlutter/fluwx/blob/master/doc/RESPONSE_CN.md)  。Android端如果是混合开发，请注册```WXEntryActivity```and```WXPayEntryActivity```；iOS端请重写```AppDelegate```中的相关方法。
+
+#### isWeChatInstalled返回false
+请查看该 [issue](https://github.com/OpenFlutter/fluwx/issues/34)  ，检查```AppDelegate```中配置是否正确。
+
+#### Kotlin报错：XXX is only available since Kotlin 1.3 and cannot be used in Kotlin 1.2

+
+SDK1.6.2
+1、xCode7.1 构建的sdk包
+2、请使用xCode7.1进行编译
+
+SDK1.6.1
+1、修复armv7s下,bitcode可能编译不过
+2、解决warning
+
+SDK1.6
+1、iOS 9系统策略更新，限制了http协议的访问，此外应用需要在“Info.plist”中将要使用的URL Schemes列为白名单，才可正常检查其他应用是否安装。
+受此影响，当你的应用在iOS 9中需要使用微信SDK的相关能力（分享、收藏、支付、登录等）时，需要在“Info.plist”里增加如下代码：
+<key>LSApplicationQueriesSchemes</key>
+<array>
+<string>weixin</string>
+</array>
+<key>NSAppTransportSecurity</key>
+<dict>
+<key>NSAllowsArbitraryLoads</key>
+<true/>
+</dict>
+2、开发者需要在工程中链接上 CoreTelephony.framework
+3、解决bitcode编译不过问题
+
+SDK1.5
+1、废弃safeSendReq:接口，使用sendReq:即可。
+2、新增+(BOOL) sendAuthReq:(SendAuthReq*) req viewController : (UIViewController*) viewController delegate:(id<WXApiDelegate>) delegate;
+支持未安装微信情况下Auth,具体见WXApi.h接口描述
+3、微信开放平台新增了微信模块用户统计功能，便于开发者统计微信功能模块的用户使用和活跃情况。开发者需要在工程中链接上:SystemConfiguration.framework,libz.dylib,libsqlite3.0.dylib。
