[英]Get word from tap in UITextView
I'm trying to get a word from a tap. 我正试着从水龙头里得到一个字。 The following function's
sender
is from the UIGesture
on the UITextView
, sentence. 以下函数的
sender
来自UITextView
上的UIGesture
,句子。
- (IBAction)printWordSelected:(id)sender {
NSLog(@"Clicked");
CGPoint pos = [sender locationInView:self.view];
UITextView *_tv = sentence;
NSLog(@"Tap Gesture Coordinates: %.2f %.2f", pos.x, pos.y);
//eliminate scroll offset
pos.y += _tv.contentOffset.y;
//get location in text from textposition at point
UITextPosition *tapPos = [_tv closestPositionToPoint:pos];
//fetch the word at this position (or nil, if not available)
UITextRange * wr = [_tv.tokenizer rangeEnclosingPosition:tapPos withGranularity:UITextGranularityWord inDirection:UITextLayoutDirectionRight];
NSLog(@"WORD: %@", [_tv textInRange:wr]);
}
This is what I already have, but it prints the word out as NULL 这是我已经拥有的,但它将单词输出为NULL
“尝试将pos更改为pos = [sender locationInView:_tv],然后删除pos.y调整。 - rmaddy”
