Ios: Rounded Rectangle with Border Bleeds Color

iOS: Rounded rectangle with border bleeds color

You could try to use a CAShapelayer with a circular path as the mask for the Layer instead of using the corner radius.

Alternatively you can place the image view in a container that has the border and is one/two pixel larger.

Why is there a rough black edge when rounding corner of UIButton?

What you're seeing is your profile image (the person's face) bleeding through the edge. This is because the border is anti-aliased and so has small amounts of transparency through which the profile image can bleed.

Since you're clipping the profile image and the border together, there's nothing stopping the profile image from extending through the border. (i.e. clipsToBounds won't clip the content to the inside of the border; it clips everything to the outside of the border) You can prove this by using a bright red image: you'll see a bright red fringe.

If you can just make the profile image circular and the right size beforehand (either offline or in code) then you'll avoid this problem.

The other solutions I see are to either implement your own drawRect: method and do the drawing yourself or to create another sub-layer of the button to hold the image which is clipped in the same way, but without the border. (Either way, you probably need to make your own UIControl for this rather than using UIButton, as manipulating the button's layers could lead to weird behavior.)

Edit: Here are some other solutions, too: iOS: Rounded rectangle with border bleeds color

iOS Select Rounded Corners Background Color

This works for me.

Select option with an arrow img:

SwiftUI: add border to view without bleeding out?

How can I make the border stay inside the overlay bounds?

Use strokeBorder(_:lineWidth:antialiased:) instead — this draws an inner stroke.

Button(action: {}) {
    Text("Button")
        .padding()
        .foregroundColor(.white)
}
.background(Color(.gray))
.overlay(
    RoundedRectangle(cornerRadius: 10)
        .strokeBorder(.red, lineWidth: 4) /// here!
)

How to prevent backgroundColor of UISegmentedControl bleeding beyond segmented border

Set the segment control's layer's corner radius to 4.0. It should help. You may need to import QuartzCore to be able to access the layer's properties.

segment.layer.cornerRadius = 4.0;
segment.clipsToBounds = YES;

Two UIButton form one having gradient color and another having border and rounded corner

Pradip it's better to add buttons in UIView. It will be easy for you to manage. I made UI like you want using UIView. See this,

let button = UIButton.init(frame: CGRect.init(x: 0, y: 250, width: 200, height: 100))
    button.setTitle("HI", for: .normal)
    button.addTarget(self, action: #selector(self.btnTapped(pageNo:)), for: .touchUpInside)
    self.view.addSubview(button)

    let view = UIView.init(frame: CGRect.init(x: 50, y: 250, width: 250, height: 50))
    view.backgroundColor = UIColor.red
    self.view.addSubview(view)

    let btnMale = UIButton.init(type: .custom)
    btnMale.frame = CGRect.init(x: 0, y: 0, width: 125, height: 50)
    btnMale.setTitle("Male", for: .normal)

    btnMale.applyGradient(colours: [UIColor.yellow,UIColor.red])

    view.addSubview(btnMale)

    let btnFemale = UIButton.init(type: .custom)
    btnFemale.frame = CGRect.init(x: 125, y: 0, width: 125, height: 50)
    btnFemale.setTitle("Female", for: .normal)
    view.addSubview(btnFemale)

    view.layer.cornerRadius = 25
    view.clipsToBounds = true

Output of above code will look like this.
