有没有办法用开关状态的自定义图形来实现 UISwitch？或者作为另一种选择，具有 UISwitch 功能的 UIButton？

UIButton 已经支持“切换”功能。

只需在 Interface Builder 中为“选定状态配置”设置不同的图像，并使用 UIButton 的 selected 属性来切换其状态。

将图像设置为在选定状态下显示：

[button setImage:[UIImage imageNamed:@"btn_graphics"] forState:UIControlStateSelected];

然后在选择器内部进行触摸时，设置：

button.selected = YES;

如果您希望取消另一个按钮的选择，请设置：

otherButton.selected = NO;

set the image to show on selected state:

[button setImage:[UIImage imageNamed:@"btn_graphics"] forState:UIControlStateSelected];

and then on touch up inside selector, set:

button.selected = YES;

if you want this to cancel another button's selection, set:

otherButton.selected = NO;

为了构建上面 PGB 和 nurne 所说的内容，在设置状态并附加选择器（事件方法）后，您需要将此代码放入该选择器中。

- (IBAction)cost:(id)sender 
{
    //Toggle current state and save
    self.buttonTest.selected = !self.buttonTest.selected;

    /**
     The rest of your method goes here.
     */
}

To build on what PGB and nurne said above, after you set your states and attach a selector (event method) you would want to put this code in that selector.

- (IBAction)cost:(id)sender 
{
    //Toggle current state and save
    self.buttonTest.selected = !self.buttonTest.selected;

    /**
     The rest of your method goes here.
     */
}

对于有编程倾向的：

-(void) addToggleButton {
    CGRect aframe = CGRectMake(0,0,100,100);

    UIImage *selectedImage = [UIImage imageNamed:@"selected"];
    UIImage *unselectedImage = [UIImage imageNamed:@"unselected"];

    self.toggleUIButton = [[UIButton alloc] initWithFrame:aframe];
    [self.toggleUIButton setImage:unselectedImage forState:UIControlStateNormal];
    [self.toggleUIButton setImage:selectedImage forState:UIControlStateSelected];
    [self.toggleUIButton addTarget:self 
                            action:@selector(clickToggle:) 
                  forControlEvents:UIControlEventTouchUpInside];
    [self addSubview:self.toggleUIButton];
}

-(void) clickToggle:(id) sender {
    BOOL isSelected = [(UIButton *)sender isSelected];
    [(UIButton *) sender setSelected:!isSelected];
}

For programmatically inclined:

-(void) addToggleButton {
    CGRect aframe = CGRectMake(0,0,100,100);

    UIImage *selectedImage = [UIImage imageNamed:@"selected"];
    UIImage *unselectedImage = [UIImage imageNamed:@"unselected"];

    self.toggleUIButton = [[UIButton alloc] initWithFrame:aframe];
    [self.toggleUIButton setImage:unselectedImage forState:UIControlStateNormal];
    [self.toggleUIButton setImage:selectedImage forState:UIControlStateSelected];
    [self.toggleUIButton addTarget:self 
                            action:@selector(clickToggle:) 
                  forControlEvents:UIControlEventTouchUpInside];
    [self addSubview:self.toggleUIButton];
}

-(void) clickToggle:(id) sender {
    BOOL isSelected = [(UIButton *)sender isSelected];
    [(UIButton *) sender setSelected:!isSelected];
}
