如何将NSInteger转换为二进制(字符串)值

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];
}

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);

Binary string: 1010
