錯誤消息

Question

func updateSearchResultsForSearchController(searchController: UISearchController) { 

    self.filteredfarger.removeAll(keepCapacity: false) 

在這裏，我得到的錯誤

"Immutable value of type '[(String)]' only has mutating members named 'removeAll'"

let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!) 
    let array = (self.TitleList as NSArray).filteredArrayUsingPredicate(searchPredicate) 
    self.filteredfarger = array as! [String] 

在這裏，我得到的錯誤：

"Cannot assign 'filteredfarger' in 'self'

self.tableView.reloadData() 
} 

非常感謝你的幫助

Answer 1

似乎filteredfarger是不可變的。你是用'let'還是'var'來定義它？
