大佬教程收集整理的这篇文章主要介绍了ios如何使UITextView检测一下？，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"touchesBegan"); //test UITouch *touch = [event allTouches] anyObject]; if ([touch tapCount] == 2) { NSLog (@"tapcount 2"); [self.textview becomeFirstResponder]; } else if ([touch tapCount] == 1) { NSLog (@"tapcount 1"); [self.textview becomeFirstResponder]; [self.view performSELEctor:@SELEctor(SELEct:)]; } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesBegan:touches withEvent:event]; NSLog(@"touchesMoved"); } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"****touchesEnded"); [self.nextResponder touchesEnded: touches withEvent:event]; NSLog(@"****touchesEnded"); [super touchesEnded:touches withEvent:event]; NSLog(@"****touchesEnded"); } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesCancelled:touches withEvent:event]; NSLog(@"touchesCancelled"); }
我的问题：
我想在UITextView上点击一次即可模拟两个水龙头,这是该代码中的textview.但是当我在textview上点击一次或两次时,我只能从一个和两个水龙头得到NSLog,只有在外面.我应该怎么做才能使它工作？
//..@L_480_5@me stuff above here probably in you're controllers viewDidLoad UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@SELEctor(singleTapRecognized:)]; singleTap.numberOfTapsrequired = 1; [someTextView addGestureRecognizer:singleTap]; [singleTap release]; UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@SELEctor(doubleTapRecognized:)]; doubleTap.numberOfTapsrequired = 2; [someTextView addGestureRecognizer:doubleTap]; [doubleTap release];
选择器就像：
- (void)singleTapRecognized:(UIGestureRecognizer *)gestureRecognizer { NSLog(@"single tap"); // ...etc } - (void)doubleTapRecognized:(UIGestureRecognizer *)gestureRecognizer { NSLog(@"double tap"); // ...etc }
以上是大佬教程为你收集整理的ios如何使UITextView检测一下？全部内容，希望文章能够帮你解决ios如何使UITextView检测一下？所遇到的程序开发问题。
