我想问如何将十六进制NSString转换为长值

Question

Answer 1

尝试使用这个

NSString *str = @"FFFF00FF";
NSScanner* scanner = [NSScanner scannerWithString: str];
unsigned long long longValue;
[scanner scanHexLongLong: &longValue];
NSLog(@"LongValue = %lld", longValue);

我希望它能帮助你。

Answer 2

long *longString = [YourString longLongValue];

Answer 3

NSString *str = @"FFFF00FF";
