Cocoa touch 如何在UITextview中打印所选文本？

如何在

UITextView

中打印所选文本？

为UITextView创建一个出口，比如说

yourTextViewName

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    NSLog (@"This is selected text in UITextView %@", selectedText);
}

（确保其已连接，以防未使用拖动功能。）

然后在任何方法中使用此语句

NSString *selectedText = [textView.text substringWithRange:[textView selectedRange]];
NSLog (@"This is selected text in UITextView %@", selectedText);

我知道这一点已经得到了回答，但我想进一步澄清。我已经创建了几个动态UITextView，希望能够简单地检测用户单击了哪个

将此添加到UITextView:

_yourTextViewName.text = [_yourTextViewName.text substringWithRange:[_yourTextViewName selectedRange]];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapRecognized:)];
singleTap.numberOfTapsRequired = 1;
[textView addGestureRecognizer:singleTap];

UITextView *selectedTextView = (UITextView *)gestureRecognizer.view;

我使用的不同之处：

_yourTextViewName.text = [_yourTextViewName.text substringWithRange:[_yourTextViewName selectedRange]];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapRecognized:)];
singleTap.numberOfTapsRequired = 1;
[textView addGestureRecognizer:singleTap];

UITextView *selectedTextView = (UITextView *)gestureRecognizer.view;

将其添加到ViewController以识别用户点击：

_yourTextViewName.text = [_yourTextViewName.text substringWithRange:[_yourTextViewName selectedRange]];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapRecognized:)];
singleTap.numberOfTapsRequired = 1;
[textView addGestureRecognizer:singleTap];

UITextView *selectedTextView = (UITextView *)gestureRecognizer.view;

当用户更改所选文本时，如何使用live UItextview（void）textViewDidChangeSelection:（UITextView*）textView{NSString*selectedText=[textView.text substringWithRange:[textView selectedRange]]；NSLog（@“这是UITextView%@中的选定文本”，selectedText）；//发布此答案后，在选择或更改文本时调用此方法，我在丹尼尔的回答中读到了你的评论。请告诉我你到底想做什么？就像我的例子一样。。是否要自动更新

@“某些文本”

？
