Question

UIImage *segmentSelected = [[UIImage imageNamed:@"Button_on"] resizableImageWithCapInsets2:UIEdgeInsetsMake(7, 7, 7, 7)];
UIImage *segmentUnselected = [[UIImage imageNamed:@"Button_off"] resizableImageWithCapInsets2:UIEdgeInsetsMake(7, 7,7,7)];

for (UIButton * button in @[self.catalog,self.business]) {
    [button setBackgroundImage:segmentSelected forState:UIControlStateSelected];
    [button setBackgroundImage:segmentUnselected forState:UIControlStateNormal];
}
self.business.selected=true;
[self.business setTitle:@"Business" forState:UIControlStateNormal];
[self.catalog setTitle:@"Catalog" forState:UIControlStateNormal];

结果是文本仅在我按住按钮时显示。不是默认的。

怎么了？

Answer 1

为所有州设置标题：

[self.business setTitle:@"Business" forState:UIControlStateNormal];
[self.catalog setTitle:@"Catalog" forState:UIControlStateNormal];
[self.business setTitle:@"Business" forState: UIControlStateHighlighted];
[self.catalog setTitle:@"Catalog" forState: UIControlStateHighlighted];
[self.business setTitle:@"Business" forState: UIControlStateSelected];
[self.catalog setTitle:@"Catalog" forState: UIControlStateSelected];

工作？

Answer 2

这必须是一个错误。

将文本颜色更改为其他颜色可解决问题。但我想要白色。所以我所做的就是有2个白色的盒子。

“默认”白色和“白色”白色。

将东西变成白色白色，然后就可以了。

为什么文本不显示UIButton
