使UIButton大于其图像

Question

I have created a number of UIButton in my iOS application using the interface builder. Each UIButton also has its own image (no title).

I would like to increase the size of the button without disturbing the image size inside of it (making the touch-area bigger without changing the image size).

Is this possible to do using the interface builder? I have played around with pretty much every option in the button page but have not find anything yet?

Answer 1

found the answer finally here

In Xcode 8 the button content/title/image insets have moved to the Size Inspector tab but we all know that and it's still not working, but there is one more step in the alignment in the below image

Answer 2

May be you want to increase the button's focus area, but the button's image still not be changed. I have two ways.

1. the image you can use UIImageView to addSubView // To set imageView's position with freedom. Then override the function:

2. After set button's frame, then set the image's position and size .eg: [button setImageEdgeInsets:UIEdgeInsetsMake(up, left,bottom, right)];

Answer 3

You need to set button's height and width as per require (if autolayout enable) . it should be larger than image size .

And now set button's contentEdges :

button.contentEdgeInsets = UIEdgeInsetsMake(15, 20, 10, 10);  //Change x,y,width,height as per your requirement.
