小编Joa*_*olt的帖子

我想检查一下我UILabel是否感动了.但我还需要更多.文字被触动了吗？现在我只有在UILabel使用这个触摸框架时才会得到true/false :

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch = [[event allTouches] anyObject];
    if (CGRectContainsPoint([self.currentLetter frame], [touch locationInView:self.view]))
    {
        NSLog(@"HIT!");
    }
}

有没有办法检查这个？一旦我触摸到信件外面的某个地方,UILabel我就会想要归还.

我想知道实际黑色渲染的"文字像素"何时被触及.

谢谢!

我使用的特定字体遇到了一些麻烦.它是为学校制作的,因此A和Å的高度不同.我认为这会给我的UIButton带来麻烦.我试图解决它,但似乎无法做到正确.这是我上次尝试过的:

[self setValue:[UIFont fontWithName:@"fontname" size:220] forKeyPath:@"button1.font"];
[self setValue:[UIFont fontWithName:@"fontname" size:220] forKeyPath:@"button2.font"];
[self setValue:[UIFont fontWithName:@"fontname" size:220] forKeyPath:@"button3.font"];
[button1 setTitle:@"A" forState:UIControlStateNormal];
[button2 setTitle:@"Å" forState:UIControlStateNormal];
[button3 setTitle:@"Å" forState:UIControlStateNormal];
[button2 setBackgroundColor:[UIColor blackColor]];
[button2 setFrame:CGRectMake(button2.frame.origin.x, button2.frame.origin.y, button2.frame.size.width, button2.frame.size.height+100)];
[button2.titleLabel setFrame:CGRectMake(button2.frame.origin.x, button2.frame.origin.y, button2.frame.size.width, button2.frame.size.height)];
button2.contentVerticalAlignment = UIControlContentVerticalAlignmentBottom;

这是结果:

如您所见,Å未正确显示.我怎样才能解决这个问题？

谢谢!

最好的问候,Joakim
