如何将NSInteger转换为二进制(字符串)值

要将NSInteger转换为二进制字符串值，您可以使用以下步骤：

将NSInteger转换为二进制数值：

NSInteger number = 10;
unsigned int binaryValue = (unsigned int)number;

将二进制数值转换为字符串：

NSMutableString *binaryString = [NSMutableString stringWithCapacity:sizeof(unsigned int) * 8];
for (int i = sizeof(unsigned int) * 8 - 1; i >= 0; i--) {
    unsigned int bit = (binaryValue >> i) & 1;
    [binaryString appendFormat:@"%d", bit];
}

现在，binaryString变量包含二进制表示形式的字符串。在这个例子中，number的值为10，二进制表示为1010。

以下是完整的代码示例：

NSInteger number = 10;
unsigned int binaryValue = (unsigned int)number;

NSMutableString *binaryString = [NSMutableString stringWithCapacity:sizeof(unsigned int) * 8];
for (int i = sizeof(unsigned int) * 8 - 1; i >= 0; i--) {
    unsigned int bit = (binaryValue >> i) & 1;
    [binaryString appendFormat:@"%d", bit];
}

NSLog(@"Binary string: %@", binaryString);

这段代码将输出：
