我想从“ title ”键中获取所有值的数组
// Create variable
var arrSportsList:[[String:String]] = []
// viewDidLoad code
arrSportsList = [
["title":"Cricket"],
["title":"Soccer"],
["title":"American Football"],
["title":"Ice Hockey"],
["title":"Tennis"],
["title":"Baseball"],
["title":"Basketball"],
]
我想在选择器视图中使用这个标题。
使用compactMap(_:)方法从所有字典中获取标题值。如果任何字典不包含标题键，它将被忽略
var arrSportsList:[[String:String]] = []
// viewDidLoad code
arrSportsList = [
["title1":"anothergame"],
["title":"Cricket"],
["title":"Soccer"],
["title":"American Football"],
["title":"Ice Hockey"],
["title":"Tennis"],
["title":"Baseball"],
["title":"Basketball"],
]
let titleArr = arrSportsList.compactMap { $0["title"] }
print(titleArr)//Cricket,Soccer,American Football,Ice Hockey,Tennis,Baseball,Basketball
