假设问题是En Dash或Em Dash字符，这里是一个示例解析。如果你的角色不同，请查看UTF8数据，然后使用它。

NSString *enDashCharacter = [NSString stringWithUTF8String:"\xe2\x80\x93"];
NSString *emDashCharacter = [NSString stringWithUTF8String:"\xe2\x80\x94"];
NSLog(@"enDashCharacter: %@", enDashCharacter);
NSLog(@"emDashCharacter: %@", emDashCharacter);

NSString *textString = [NSString stringWithFormat:@"1-2 3%@4 5%@6", enDashCharacter,emDashCharacter];
NSData *textData = [textString dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"textString: '%@'", textString);
NSLog(@"textData: %@", textData);

NSString *newString = textString;
newString = [newString stringByReplacingOccurrencesOfString:enDashCharacter withString:@"-"];
newString = [newString stringByReplacingOccurrencesOfString:emDashCharacter withString:@"-"];
NSLog(@"newString:  '%@'", newString);

NSData *newStringData = [newString dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"newStringData: %@", newStringData);

NSLog输出：
enDashCharacter： -
emDashCharacter： -
textString：'1 - 2 3 - 4 5 - 6'
textData：＆lt; 2031202d 20322033 20e28093 20342035 20e28094 203620＆gt;

newString：'1 - 2 3 - 4 5 - 6'
newStringData：＆lt; 2031202d 20322033 202d2034 2035202d 203620＆gt;
