iPhone：调用textViewDidChange安全吗？
我正在查看 UIViewController 中的代码，它符合 UITextViewDelegate 协议，并且有一个名为 someTextView 的实例变量。
someTextView.text = @"some text";
[self textViewDidChange:someTextView];
这样安全吗？在我看来这不符合犹太洁食。是否有必要调用 textViewDidChange:？ someTextView.text = @"some text" 不会自动调用它吗？
我正在调试此错误 iPhone Objective-C：键盘不会'有时会用 resignFirstResponder 隐藏
I'm looking at code in a UIViewController that conforms to the UITextViewDelegate protocol and has an instance variable called someTextView.
someTextView.text = @"some text";
[self textViewDidChange:someTextView];
Is that safe? That doesn't look Kosher to me. Is it even necessary to call textViewDidChange:? Won't it get called automatically by someTextView.text = @"some text"?
I'm debugging this error iPhone Objective-C: Keyboard won't hide with resignFirstResponder, sometimes

textViewDidChange:手动调用 (UIView-) 委托方法是否安全且好主意取决于该方法内部的代码。有时这样做是有正当理由的。
但您的错误很可能不是由此代码片段引起的。

textViewDidChange:If it's safe and a good idea to call (UIView-) delegate methods manually depends on the code inside of the method. Sometimes there are valid reasons to do this.
But your bug is most likely not caused by this snippet.
