问题描述
任何人有在Objective-C的一些code到NSInteger的或的NSString转换为二进制字符串?
Anybody has some code in objective-c to convert a NSInteger or NSString to binary string?
例如:
56 - > 111000
56 -> 111000
有计算器中的一些code试图做到这一点,但它doesn't的工作。
There are some code in stackoverflow that try do this, but it doesn´t work.

推荐答案
不知道这对SO例子没有为你工作,但Adam在这里罗森菲尔德的回答似乎工作。我已经更新它删除编译器警告:
Not sure which examples on SO didn't work for you, but Adam Rosenfield's answer here seems to work. I've updated it to remove a compiler warning:
// Original author Adam Rosenfield... SO Question 655792
NSInteger theNumber = 56;
NSMutableString *str = [NSMutableString string];
for(NSInteger numberCopy = theNumber; numberCopy > 0; numberCopy >>= 1)
{
// Prepend "0" or "1", depending on the bit
[str insertString:((numberCopy & 1) ? @"1" : @"0") atIndex:0];
}
NSLog(@"Binary version: %@", str);
