How to get back the UIButton border in iOS 7?
提问by ohho
I built an old project in iOS SDK 6.1 in Xcode 5. However, the UIbutton is borderless when the app runs on an iPhone running iOS 7. I have checked the .xibis "Builds for" > "Project Deployment Target (5.0)":
我在 Xcode 5 的 iOS SDK 6.1 中构建了一个旧项目。但是，当应用程序在运行 iOS 7 的 iPhone 上运行时，UIbutton 是无边框的。我检查了.xib“Builds for”>“Project Deployment Target (5.0)”：
How can I config Xcode 5 to build the project to show an iOS 6.1-style UIButton?

you can create a category:
您可以创建一个类别：
- (void)setRoundedBorder:(float) radius borderWidth:(float)borderWidth color:(UIColor*)color
{
CALayer * l = [self layer];
[l setMasksToBounds:YES];
[l setCornerRadius:radius];
// You can even add a border
[l setBorderWidth:borderWidth];
[l setBorderColor:[color CGColor]];
}

If you don't want to introduce any of the iOS 7 changes changing the SDK is not enough. You shouldn't leave the Interface Builder "Opens in" property unchanged as well.
如果您不想引入任何 iOS 7 更改，更改 SDK 是不够的。您也不应该让 Interface Builder 的“Opens in”属性保持不变。
I leave mine in "Xcode 4.6" and everything looks as it should.
我将我的留在“Xcode 4.6”中，一切看起来都应该如此。
I think the only advantage you would take is with the new auto-layout.
我认为您可以利用的唯一优势是新的自动布局。
