如何在UITextView中设置光标的位置 [英] How to set the position of the cursor in UITextView

问题描述

我的iPhone应用程序中有一个可编辑的UITextView。

I have an UITextView in my iPhone app which is editable.

只要用户选择特定功能，就会在UITextView内创建新按钮。

New button is created inside the UITextView whenever user select a specific function.

由于按钮始终位于文本视图的左侧，我需要将光标放在按钮的右侧，以便用户可以看到它们的内容正在打字。
我似乎无法找到一个记录（或未记录）的方法来设置光标的位置。

As the button is always placed on the left side in the text view, I need to position the cursor on the right side of the button so that user can see what they are typing. I can't seem to find a documented (or undocumented) method to set location of the cursor.

是否有人有任何想法或有任何其他人实现类似的东西？

Does anybody have any ideas or has anybody else achieved anything similar?

推荐答案

我知道这已经很晚了，但我想我可以帮助那些陷入困境的人（像我一样）。

I know this is VERY late, but I thought I could help people stuck in this (like me).

performSelector：withObject：afterDelay 似乎工作正常（其他答案对某些奇怪的人不起作用）原因）：

The performSelector:withObject:afterDelay seems to work fine (the other answers just wouldn't work for some strange reason):

- (void)textViewDidBeginEditing:(UITextView *)inView 
{ 
[self performSelector:@selector(setCursorToBeginning:) withObject:inView afterDelay:0.01]; 
} 

- (void)setCursorToBeginning:(UITextView *)inView 
{ 
//you can change first parameter in NSMakeRange to wherever you want the cursor to move
inView.selectedRange = NSMakeRange(3, 0); 
}
