转换十六进制NSString到long型

比如说我要将这个字符串转换成long型：

NSString *str = @"FFFF00FF";

谢谢您的帮助。

NSString *str = @"FFFF00FF";
NSScanner* scanner = [NSScanner scannerWithString: str];

unsigned long long longValue;
[scanner scanHexLongLong: &longValue];
NSLog(@"LongValue = %lld", longValue);

使用这段代码

NSString *str = @"FFFF00FF";

long longstring=[str longLongValue];

NSLog(@"%ld",longstring);

试试看吧
