The Swift Code之设置UIButton的不同方式创建,以及不同的状态和外观

概述在设置rootViewController之后,在这个control里的viewDidLoad方法里,添加相应的代码.设置了9个不同类型的UIButton 创建了有状态的button,以及添加button事件 创建没有状态的button 创建一个图片加文字的按钮,只要图片就不需要设置title 从系统定义的button类型创建button 创建禁止button 创建一个圆角button 部分圆角b

在设置rootVIEwController之后,在这个control里的vIEwDIDLoad方法里,添加相应的代码.设置了9个不同类型的UIbutton

创建了有状态的button,以及添加button事件

创建没有状态的button

创建一个图片加文字的按钮,只要图片就不需要设置Title

从系统定义的button类型创建button

创建禁止button

创建一个圆角button

部分圆角button,主要是利用layer的mask属性,在通过CAShaperLayer和UIBezIErPath来画

创建折角button

创建border的button

效果如下
