iOS 4.3在模拟器上的UITextField自动更正崩溃

Question

UITextField的自动更正会在iOS 4.3 sdk构建目标的模拟器上崩溃我的应用程序.使用iOS 4.2 sdk在设备和模拟器中正常工作.

有其他人遇到过这个问题吗？我正在考虑4.3 sdk的错误？

只要输入第二个字符.堆栈跟踪

有时,您会看到一个简单的跟踪,它只是从main开始,然后立即停止objc_assign_ivar.键入文本字段(例如UISearchBar)时也会发生这种情况.

Answer 1

在模拟器上,打开"设置" - >"键盘"并关闭所有选项.这可以防止崩溃(直到bug被解决).

Answer 2

我遇到了同样的问题,在Lion Developer Preview 2上运行4.3模拟器.这是Lion上模拟器中的一个错误.我暂时禁用了自动更正(setAutocorrectionType:UITextAutocorrectionTypeNo).

Answer 3

我们必须按照以下步骤更新Simulator 4.3:

1. 转到Xcode - >首选项 - >下载
2. 更新iOS 4.3模拟器

并重置模拟器并再次运行它.完成.
