更新xcode到9.4后，无法响应本机ios构建失败。错误是“ NSInteger”类型的值

Question

错误代码消息为

'NSInteger'类型的值不应用作格式参数；添加一个明确的强制转换为'long' 用'JS之前的％ld事件-尝试使JS更快。“，self.text，（long）'<'替换JS之前的'％zd事件-尝试使您的JS更快。 / p>

我的package.json文件如下。

我能够在xcode 9.2版中正常构建。但是，由于9.2版不支持iOS 11.4的内部版本，因​​此我升级了xcode版本。从那时起，我一直在构建失败。

谢谢。

Answer 1

这很简单。

只需单击xcode修复按钮

Answer 2

仅当您使用的RN 0.56以下但XCode更新为9+时，这才是问题。我正在RN 0.56中解决此问题，因为它们在发行版中将XCode 9称为最低版本-https://github.com/react-native-community/react-native-releases/blob/master/CHANGELOG.md#xcode-9-is-now-the-minimum-required-version

我找到了修复按钮（re：react native ios build is failed after update xcode to 9.4. error is Values of type 'NSInteger'），但是我必须每次都运行build，当遇到这些错误时，我必须找到并按下修复按钮。我认为只有两个地方需要执行此操作，但是如果可以找到所有这些地方，而不是构建然后修复一个错误，然后再重复构建直到没有其他地方，那就更好了。

显然，这与%zd有关，需要%ld并用大写字母long来填充。

这是修复按钮：

1. 单击红点：

2. 修复按钮出现：

3. 使用修复程序重新格式化：
