我有這樣的NSArray。我想過濾NSMutableDictionary的文件名爲SearchString的NSArray。意思是我使用searchBarController，所以當我搜索一些東西時，它應該在字典中過濾具有搜索文件名的數組。 我該怎麼做？有什麼建議麼？

感謝

var fileterArray: NSArray = yourArray.filteredArrayUsingPredicate(NSPredicate(format: "self.%@ contains[c] %@", "filename", "SearchString")) 

print(fileterArray)
