导航栏上有两个以上的rightBarButtonItem

Question

我想在导航栏上有三个rightBarButtonItems。 添加，修改和删除。

我无法使用Interface Builder。

有人知道如何以编程方式执行此操作吗？

Answer 1

将一个条形按钮项数组添加到navigationItem.rightBarButtonItems

public class Main {

    public static void main(String[] args) {

        int binInt = 10110111;
        String binString = "10110111";
        BinaryConverter convertedInt = new BinaryConverter(binInt);
        BinaryConverter convertedString = new BinaryConverter(binString);

        System.out.println("Binary as an int, to decimal: " + convertedInt.getDecimal());
        System.out.println("Binary as a string, to decimal: " + convertedString.getDecimal());

    }

}

public class BinaryConverter {

    private final int base = 2;
    private int binaryInt;
    private String binaryString;
    private int convertedBinaryInt;

    public BinaryConverter(int b) {
        binaryInt = b;
        convertedBinaryInt = Integer.parseInt(Integer.toString(binaryInt), base);
    }

    public BinaryConverter(String s) {
        binaryString = s;
        convertedBinaryInt = Integer.parseInt(binaryString, base);
    }

    public int getDecimal() {
        return convertedBinaryInt;
    }

}
