Is there a way to handle this conversion in objective-c?

推荐答案

您可能正在寻找:

NSString *string = (some string with non-ASCII characters in it);
char const *string_as_latin1 = [string cStringUsingEncoding:NSISOLatin1StringEncoding];

或者可能是这样:

NSData *data_latin1 = [string dataUsingEncoding:NSISOLatin1StringEncoding allowLossyConversion:YES];
