推荐答案

NSString *str = @"Happy to help you U0001F431";

NSData *data = [str dataUsingEncoding:NSNonLossyASCIIStringEncoding];
NSString *valueUnicode = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];


NSData *dataa = [valueUnicode dataUsingEncoding:NSUTF8StringEncoding];
NSString *valueEmoj = [[NSString alloc] initWithData:dataa encoding:NSNonLossyASCIIStringEncoding];

_lbl.text = valueEmoj;

SWIFT - 3 或更高

    let str = "Happy to help you U0001F431"

    let data : NSData = str.dataUsingEncoding(NSNonLossyASCIIStringEncoding)!
    let valueUnicode : String = String(data: data, encoding: NSUTF8StringEncoding)!

    let dataa   : NSData = valueUniCode.dataUsingEncoding(NSUTF8StringEncoding)!
    let valueEmoj : String = String(data: dataa, encoding: NSNonLossyASCIIStringEncoding)!

SWIFT - 4 或更高

    let str = "Happy to help you U0001F431"

    let data : NSData = str.dataUsingEncoding(NSNonLossyASCIIStringEncoding)!
    let valueUnicode : String = String(data: data as Data, encoding: String.Encoding.utf8)!

    let dataa   : NSData = valueUnicode.data(using: String.Encoding.utf8)! as NSData
    let valueEmoj : String = String(data: dataa as Data, encoding: String.Encoding.nonLossyASCII)!
