iOS 5中的屏幕外UITextView不可见/明文 [英] Offscreen UITextView invisible/clear text in iOS 5
问题描述
我有一个从笔尖加载的屏幕外UITextView实例,当用户点击评论按钮时,该笔实体移动到屏幕框架中。 enter使用的任何文本都是不可见的。如果用户旋转设备,则会显示文本。
I've got an off-screen UITextView instance loaded from a nib which is moved into the screen frame when the user taps a "comment" button. Any text the enter uses is invisible. If the user rotates the device, the text appears.
我尝试过抛出setNeedsDisplay和setNeedsLayout,以及设置text,textColor和font属性在之后它出现在屏幕上,没有运气。
I've tried throwing setNeedsDisplay and setNeedsLayout, as well as setting the text, textColor, and font properties after it comes on screen with no luck.
我有一个示例Xcode项目,展示了bug。
I have an example Xcode project demonstrating the bug.
有什么建议吗?
推荐答案
我无法解决这个问题所以我等到视图在屏幕上完成动画并重新创建UITextView,删除旧的,然后用新的替换它。
I couldn't solve this problem so I wait until the view has finished animating on screen and recreate the UITextView, remove the old one, and replace it with the new one.
这是非常不优雅的我甚至需要保留一个BOOL ivar来记住我是否已经替换了文本视图(或不是)。
It's very inelegant since I even need to keep a BOOL ivar for remembering if I've already replaced the text view (or not).
