Xamarin.ios Show round Picture

When you do the project, you will definitely encounter the display of circular pictures.

Use UIButton to display a circular picture, to facilitate the next click event, and through the set of rounded corners to achieve the purpose of the circular picture.

It's simple, just look at the code:

Avatar
		private UIButton _headerimg = null;
		Public UIButton headerimg
		{
			get
			{
				if (_headerimg = null)
				{
					_headerimg = new UIButton ();
					_headerimg.setimage (Headuiimage, uicontrolstate.normal);

					Click event
					_headerimg.touchupinside + = (sender, E) => { 
						
					};

					_headerimg.layer.maskstobounds = true;

					Note here: You need to set the fillet size to half the height of your button.
					_headerimg.layer.cornerradius = 33f;
				}
				Return _headerimg
			}
		}

Finish.
