How do I make a UISwitch under iOS 7 not take the background colour of the view behind it?

Question

It looks like this whenever off:

While I'd prefer more of a grey background. Do I really have to use a UIImageView?

Solution 1

Here is how I changed the fill color of my iOS7 UISwitch.

First you need to import QuartzCore.

#import <QuartzCore/QuartzCore.h>

Then set the background color and round the UISwitch's corners.

UISwitch *mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(0.0, 0.0, 51.0, 31.0)];
mySwitch.backgroundColor = [UIColor redColor];
mySwitch.layer.cornerRadius = 16.0; // you must import QuartzCore to do this.
[self addSubview:mySwitch];

This will give you a UISwitch with a custom off (background) color.

Hope this helps someone:)

Solution 2

You can set the setOnTintColor property of your UISwitch to the color you desire.

Solution 3

You can also set this for the switch in Interface Builder. Just set the background colour of the UISwitch to whatever colour you want (white, in the example below), then set a User Defined Runtime Attribute of layer.cornerRadius = 16:

Solution 4

There's no API support for changing the off fill color of a UISwitch.

Adjusting the tintColor will only affect the outline, and adjusting the backgroundColor will affect the whole frame, including the parts outside the rounded bounds.

You either have to place a properly shaped opaque UIView behind it or - easier - use a custom open source implementation, such as MBSwitch, which allows you to set the off fill color.

Solution 5

You can also use an image as background, using the [UIColor colorWithPatternImage];

mySwitch.onTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"toggle-bg-on"]];
mySwitch.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"toggle-bg-off"]];

This refers to when it's off.

For me, this setting refers to when the switch is on. e.g.: [usePatternsSwitch setOnTintColor: [UIColor lightGrayColor]];

The day they change the shape of the switch your solution will not look fine.

The day they will change the shape of the switch I will have to recompile the app with the new SDK and then I'll change it.

Down vote, because this doesn't answer the question at all. The question is referring to the off state.

Very useful! Better to add swift version too.

Just extra thanks for pointing that properties may be set with User Defined list, not just in code.
