uibutton

In the process of development, we often encounter the button's title left-aligned way, first we will think of button.titleLabel.textAlignment = Uitextalignmentleft is not useful, But this method has been banned in iOS, that is, the use of and no effect, fortunately UIButton inherited from Uicontrol then we can use this method to implement, Button.contenthorizontalalignment = Uicontrolcontenthorizonalignmentleft, but don't think it's done, so you'll fi

Recently, I was working on a project and encountered two click events in succession. 1. uiimageview interaction is disabled by default. Solution: Just open it. Interaction among other basic controls such as uibutton and uilabel is enabled by default. The interaction of uiimageview is disabled by default.
