例如，您需要类似的东西.

As an example, you need something like this.

    UIBarButtonItem *fixedCenter = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
    fixedCenter.width = 80.0f;
    UIBarButtonItem *fixedLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
    fixedLeft.width = 40.0f;

    UIBarButtonItem *left = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"left.png"] style:UIBarButtonItemStylePlain target:self action:@selector(moveBack:)];
    UIBarButtonItem *right = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"right.png"] style:UIBarButtonItemStylePlain target:self action:@selector(moveForward:)];
