UIEdgeInset问题定位文本/图像 [英] UIEdgeInset issue positioning text/image

问题描述

我尝试制作一个 UIButton ，图片高于文字，所以我使用这段代码：

I try to make an UIButton with image upper the text, so I use this code:

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(x, y, 140, 140);
[btn setTitle:self.objMateria.titoloMateria forState:UIControlStateNormal];
[btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[btn setBackgroundColor:[UIColor clearColor]];
[btn setImage:[UIImage imageNamed:@"pala.png"] forState:UIControlStateNormal];
btn.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 20, 0);
btn.titleEdgeInsets = UIEdgeInsetsMake(120, 0, 0, 0);

问题在于，使用此代码我看不到文本，这似乎是由图片，哪里出错？

the problem is that with this code I don't see the text, that seems to be covered by the image, where is the mistake?

这里图片：

here the image:

推荐答案

试试这个

btn.imageEdgeInsets = UIEdgeInsetsMake(-20, 0, 0, 0);
btn.titleEdgeInsets = UIEdgeInsetsMake(120, -120, 0, 0);

调整 -120 的值，即 left 横向调整你的标题

Adjust the value of -120 i.e. left to horizontally fit your title
