改变iPhone应用程序中的开关颜色

问题描述：

我在iOS 3中使用 UISwitch 在我的应用中制作一个开关元素。它的默认颜色设置为蓝色，但我想将其颜色更改为棕色（除了一些令人讨厌的谣言之外，没有通过谷歌获得线索）。

I am using UISwitch in iOS 3 to make a switch element in my app. It has default color set to blue, but I want to change its color to brown (didn't get a clue via Google except some nasty rumors).

我怎么能为iOS 3中的 UISwitch 元素选择不同的颜色？

How can I choose a different color for the UISwitch element in iOS 3?

答

在iOS 3中，您可以使用未记录的功能找到答案这里。如上所述，您的应用可能会因为更改颜色而被拒绝。

In iOS 3 you will find an answer by using an undocumented feature here. As noted your app might get rejected because of changing the color.

它的开头是这样的：

UISwitch *aSwitch = [[UISwitch alloc] initWithFrame:someRectangle];
[aSwitch setAlternateColors:YES];
//Do something with aSwitch
[aSwitch release];

第五个iOS版本现在允许以书面形式执行此操作：使用属性 onTintColor 。

And the fifth iOS release now allows a documented way of doing this: with the property onTintColor.

UISwitch *s = [[UISwitch alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
s.on = YES;
s.onTintColor = [UIColor redColor];
[self.view addSubview:s];
[s release];

产生此

编辑我不知道为什么有人会通过并回滚答案，只有在对所有答案做同样的事情时才将其限制在问题中。

I have no idea why someone would come through and roll back the answer to limit it to the question only while not doing the same to all the answers.
