如何在React Native项目中配​​置AppDelegare.m

Question

我要对AppDelegate.m文件进行配置，使用24hours格式设置react-native-modal-datetime-picker。文档说要执行以下操作

The is24Hour prop is only available on Android but you use a small hack for enabling it on iOS by setting the app's default timezone as en_GB. To do so, edit your AppDelegate.m file, and add [[UIDatePicker appearance] setLocale:[[NSLocale alloc]initWithLocaleIdentifier:@"en_GB"]]; to application didFinishLaunchingWithOptions

但是我不知道我应该在AppDleate.m文件中的何处添加流动代码

我应该在哪里添加以上代码

Answer 1

如引文中所述，您应该使用didFinishLaunchingWithOptions方法添加它。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [[UIDatePicker appearance] setLocale:[[NSLocale alloc]initWithLocaleIdentifier:@"en_GB"]];
}

在AppDelegate.m文件中添加以上代码。启动过程到此完成，您应该在此处进行此类配置。
