Answer 1

试试这个:

let name  = "uploads/4/jobs/2017-02-15-05-17-05pmThe_Wolf_of_Wall_Street_-_Jordan_Belfort.pdf"
var names = name.components(separatedBy: "/")
let lastComponent = names[names.count - 1]

var nameOfFile:String = ""
let pm = lastComponent.components(separatedBy: "pm")
let am = lastComponent.components(separatedBy: "am")
if(pm.count > 1){
    nameOfFile = pm[1]
} else if(am.count > 1){
    nameOfFile = am[1]
}
print(nameOfFile)
