objective-c - UIRoundedRectButton 没有响应 UIView 类别方法

Question

我有一个 UIView 类别方法来调整 UIView 的框架：

-(void)setFrameWidth:(NSInteger)aWidth andHeight:(NSInteger)aHeight
{
    CGRect labelFrame = self.frame;
    labelFrame.size = CGSizeMake(aWidth, aHeight);
    self.frame = labelFrame;
}

但是，当我将它应用于 UIRoundedRectButton 时：

//button for options
    optionsButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [optionsButton setTitle:@"Options" forState:UIControlStateNormal];
    [optionsButton addTarget:self action:@selector(goToOptions:) forControlEvents:UIControlEventTouchUpInside];
    [optionsButton setFrameWidth:200 andHeight:50];
    optionsButton.center = CGPointMake(SCREEN_X_LENGTH_HALF, SCREEN_Y_LENGTH_TWO_THIRDS);
    [self.view addSubview:optionsButton];

它抱怨说'-[UIRoundedRectButton setFrameWidth:andHeight:]: unrecognized selector sent to instance 0x718a600'。

如何让我的类别方法在按钮上工作？
