1、上傳表情到后臺 Unicode編碼
?????NSString *uniStr = [NSString stringWithUTF8String:[comments UTF8String]];
? ? NSData *uniData = [uniStr dataUsingEncoding:NSNonLossyASCIIStringEncoding];
? ? NSString *goodStr = [[NSString alloc] initWithData:uniData encoding:NSUTF8StringEncoding] ;
2、顯示后臺返回的表情 Unicode 解碼
?????NSString *str = comments;
? ? constchar *jsonString = [str UTF8String];? // Emoji表情編解碼
? ? NSData *jsonData = [NSData dataWithBytes:jsonString length:strlen(jsonString)];
? ? NSString *goodMsg1 = [[NSString alloc] initWithData:jsonData ?encoding:NSNonLossyASCIIStringEncoding];
注：comments 上傳字符串
