NSString * str = @“FFFF00FF”;

谢谢！

Answer 1

尝试使用此

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

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

我希望它可以帮到你。

Answer 2

long *longString = [YourString longLongValue];

Answer 3

NSString *str = @"FFFF00FF";

long longstring=[str longLongValue];
