快速編碼URL如果我像這樣編碼一個字符串：var escapedString = originalString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)它逃不出斜杠/.我搜索并找到了這個目標C代碼：NSString *encodedString = (NSString *)CFURLCreateStringByAddingPercentEscapes(
NULL,
(CFStringRef)unencodedString,
NULL,
(CFStringRef)@"!*'();:@&=+$,/?%#[]",
kCFStringEncodingUTF8 );是否有一種更簡單的方式來編碼一個URL，如果不是，我如何用SWIFT寫這個呢？
