回到过去,在 Emoji 键盘成为 iOS 标准之前,您可以下载一个允许您启用和使用 Emoji 键盘的应用程序。遵循同样的概念,我是否可以定义我自己的键盘,用户可以选择在他们的 iPhone 设置中使用我自己的符号?
这适用于未越狱的 iOS 设备。如果有越狱设备的解决方案,我也会接受(出于教育目的)。
No, you cant implement a custom keyboard on a non-jailbroken iOS device which can be accessed outside your app. They were just enabling a keyboard which was already there
Basically you are not allowed to change anything outside your app. So in this case since you have to add this to settings, Apple wont allow that as per its current guidelines(Assuming that your question is about non-jailbroken iOS device where app needs to be pushed to AppStore).
