关于如何提交 Tips #10

Closed alfredcc closed 6 years ago

建议统一制作一个类似 swift-evolution 的 proposal 模板。

比如：

提议内容

iOS11 的 UISearchBar 高度改成了56个点，当放在高度为44的NavigationBar上时，和其他BarButtonItem对不齐了，可以override intrinsicContentSize方法改回44

标题

Bool 另一种更加优雅的写法

提议内容

For Bool variables, it is common to want to toggle the state of the variable. In larger (nested) structs, the duplication involved can become especially annoying:

 myVar.prop1.prop2.enabled = !myVar.prop1.prop2.enabled

It's also easy to make a mistake in the code above if there are multiple Bool vars

代码实现

 extension Bool {
     mutating func toggle() {
         self = !self
     }
 }
 myVar.prop1.prop2.enabled.toggle()
