//字符串的替换

let  ReplaceString = "http://www.aimonkey。cn"

let FilterReplace = ReplaceString.replacingOccurrences(of: "。", with: ".")

print(FilterReplace)

//字符串的删除

let str = ReplaceString.replacingOccurrences(of: "w", with: "")

print(str)

//字符串的截取

//将ReplaceString 转换为OC 的字符串使用,根据范围来截取字符串

let subString1 = (ReplaceString as NSString).substring(with: NSMakeRange(1, 3))

print(subString1)

//截取下标2 之前的字符

let subString2 = (ReplaceString as NSString).substring(to: 2)

print(subString2)

//截取下标2 之后(含有2)

let subString3 = (ReplaceString as NSString).substring(from: 2)

print(subString3)

//字符串的分割

let url  = "http://blog.****.net/hello_hwc?viewmode=list"
