如何更改OFF状态的UISwitch默认颜色？ [英] How to change UISwitch default color for OFF state?

问题描述

我想在关闭状态下更改UISwitch中onTintColor的颜色。该开关位于tableview中，并以编程方式进行切换。

I want to change the color of onTintColor in the UISwitch for the off State. The switch is in tableview and switch is made programmatically.

    [settingsSwitch setBackgroundColor:[UIColor whiteColor]];
    [settingsSwitch setTintColor:[UIColor whiteColor]];
    [settingsSwitch setThumbTintColor:[UIColor redColor]];
    [settingsSwitch setOnTintColor:[UIColor colorWithRed:138/256.0  green:9/256.0 blue:18/256.0 alpha:1]];

这是我将背景颜色设置为白色时得到的结果。

This is the result i get when i set the background color white.

没有背景我得到红色，这是我的细胞的颜色。

And without background i get red color which is the color of my cell.

这是我想要的结果，当开关打开时onTintColor应该是深红色，而在关闭状态下它应该是白色。

and this is the result i want, when switch is on the onTintColor should b dark red, and in off state it should be white.

我尝试用这行代码在开关上设置图像

i tried setting the image on switch with this line of code

[settingsSwitch setOnImage:[UIImage imageNamed:@"on.png"]];
[settingsSwitch setOffImage:[UIImage imageNamed:@"off.png"]];

但它没有改变图像。
我想改变关闭状态下开关的颜色。
希望我已经清楚地解释了我的问题。谢谢提前帮助。

But its not changing the images. i want to change the color of switch in off state. Hope i have explained my question clearly.thanks for helping in advance.

推荐答案

您可以使用以下CODE来实现要求。

You can use following CODE to fulfill requirement.

您的ViewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    [self.view setBackgroundColor:[UIColor redColor]];

    settingsSwitch.layer.cornerRadius = 16.0; // you must import QuartzCore to do this


    if (settingsSwitch.on) {
        NSLog(@"If body ");
        [settingsSwitch setThumbTintColor:[UIColor redColor]];

        [settingsSwitch setBackgroundColor:[UIColor whiteColor]];
        [settingsSwitch setOnTintColor:[UIColor whiteColor]];

    }else{
        NSLog(@"Else body ");

        [settingsSwitch setTintColor:[UIColor clearColor]];

        [settingsSwitch setThumbTintColor:[UIColor redColor]];

        [settingsSwitch setBackgroundColor:[UIColor colorWithRed:138/256.0 green:9/256.0 blue:18/256.0 alpha:1]];
    }
}

调用状态更改IBAction的方法。

- (IBAction)switchStatusChange:(UISwitch *)sender
{
    if (sender.on) {
        NSLog(@"If body ");
        [sender setThumbTintColor:[UIColor redColor]];

        [sender setBackgroundColor:[UIColor whiteColor]];
        [sender setOnTintColor:[UIColor whiteColor]];

    }else{
        NSLog(@"Else body ");

        [sender setTintColor:[UIColor clearColor]];

        [sender setThumbTintColor:[UIColor redColor]];

        [sender setBackgroundColor:[UIColor colorWithRed:138/256.0 green:9/256.0 blue:18/256.0 alpha:1]];
    }
}
