在Xcode8.0以上，xcode提供了Xcode Source Editor Extension来开发插件。
Xcode中多行注释可以command + / 来注释代码
// override func viewDidLoad() {
// super.viewDidLoad()
//
// }由于不太喜欢每一行前面都//这样显得这个页面比较乱。像整个代码块还是使用多行注释/***/，这样看起来比较简洁。
/** 2017-11-29 16:06:16
override func viewDidLoad() {
super.viewDidLoad()
}
*/所以决定自己开发有一个小插件咯。先直接填代码：
class SourceEditorCommand: NSObject, XCSourceEditorCommand {
func perform(with invocation: XCSourceEditorCommandInvocation, completionHandler: @escaping (Error?) -> Void ) -> Void {
// Implement your command here, invoking the completion handler when done. Pass it nil on success, and an NSError on failure.
// 第一个选中区域
let firstSelectObject: XCSourceTextRange = invocation.buffer.selections.firstObject as! XCSourceTextRange
let buffer = invocation.buffer
var start = firstSelectObject.start.line
var end = firstSelectObject.end.line
var startStr: String = buffer.lines[start] as! String
var endStr: String = buffer.lines[end] as! String
if start == end {
} else {
while checkSpace(str: endStr) {
if end == start {
break
}
end -= 1
endStr = buffer.lines[end] as! String
}
while checkSpace(str: startStr) {
if end == start {
break
}
start += 1
startStr = buffer.lines[start] as! String
}
}
//如果是已经注释的就去掉注释
if startStr.hasPrefix("/**") && endStr.hasPrefix("*/") {
buffer.lines.removeObject(at: end)
buffer.lines.removeObject(at: start)
completionHandler(nil)
return
}
//自己多增加了个注释时间
let dateFormatter = DateFormatter()
dateFormatter.locale = NSLocale(localeIdentifier: "zh_CN") as Locale!
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let str = dateFormatter.string(from: NSDate() as Date)
//代码块前后添加注释字符
buffer.lines.insert("*/", at: end + 1)
buffer.lines.insert("/** \(str)", at: start)
completionHandler(nil)
}
/// 是否为全是空格
func checkSpace(str: String) -> Bool {
if (str.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines) as NSString).length == 0 {
return true
}
return false
}
}
选个代码块，按下快捷键
/** 2017-11-29 16:20:02
@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) CLLocationManager *locationManager;
