let imageData = UIImagePNGRepresentation(resizedImage) 

if let imageBase64 = imageData?.base64EncodedDataWithOptions(NSDataBase64EncodingOptions (rawValue: 0)) { 
    let strBase64:String = imageBase64.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0)) 
} 

결과 문자열은 다음과 같은 : 나는 다음과 같은 코드를 사용하고

두 번째 형식 ("/"포함)을 얻는 방법을 모르겠습니다.

Answer 1

두 번 인코딩 중입니다. 그냥 해.

let strBase64 = imageData?.base64EncodedStringWithOptions([])
