模拟器上 iOS 4.3 中的 UITextField 自动更正崩溃

UITextField auto correction crash in iOS 4.3 on simulator(模拟器上 iOS 4.3 中的 UITextField 自动更正崩溃)

问题描述

UITextField 的自动更正使我的应用程序在具有 iOS 4.3 sdk 构建目标的模拟器上崩溃.在设备上和带有 iOS 4.2 sdk 的模拟器上运行良好.

The UITextField's auto correction crashes my app on the simulator with iOS 4.3 sdk build target. Works fine on the device and in the simulator with iOS 4.2 sdk.

还有其他人遇到这个问题吗?我认为它是 4.3 sdk 的错误?

Anyone else experiencing this issue? I'm figuring its a bug with the 4.3 sdk?

只要我输入第二个字符.堆栈跟踪

As soon as I type the second character. Stack Trace

有时，您会看到一个简单得多的跟踪，它只是从 main 开始，然后在 objc_assign_ivar 上立即停止.在输入文本字段(例如 UISearchBar)时也会发生这种情况.

Also at times, you will see a much simpler trace that simply starts at main, then ceases immediately on objc_assign_ivar. This happens also when typing in a text field, such as a UISearchBar.

推荐答案

在模拟器上，打开设置->键盘，关闭所有选项.这可以防止崩溃(直到错误得到解决).

On the simulator, open Settings -> Keyboard and turn OFF all the options. This prevents the crash (until the bug is addressed).
