如何将NSString转换为NSNumber

问题：

How can I convert a NSString containing a number of any primitive data type (eg int , float , char , unsigned int , etc.)? 如何转换包含许多原始数据类型（例如int ， float ， char ， unsigned int等）的NSString ？ The problem is, I don't know which number type the string will contain at runtime. 问题是，我不知道字符串在运行时将包含哪种数字类型。

I have an idea how to do it, but I'm not sure if this works with any type, also unsigned and floating point values: 我有一个方法，但是我不确定这是否适用于任何类型，也适用于无符号和浮点值：

long long scannedNumber;
NSScanner *scanner = [NSScanner scannerWithString:aString];
[scanner scanLongLong:&scannedNumber]; 
NSNumber *number = [NSNumber numberWithLongLong: scannedNumber];

Thanks for the help. 谢谢您的帮助。
