  • IOS基础学习UIButton使用详解

    第一、UIButton的定义

      UIButton *button=[[UIButton buttonWithType:(UIButtonType);

      能够定义的button类型有以下6种,

      typedef enum {

      UIButtonTypeCustom = 0, 自定义风格

      UIButtonTypeRoundedRect, 圆角矩形

      UIButtonTypeDetailDisclosure, 蓝色小箭头按钮,主要做详细说明用

      UIButtonTypeInfoLight, 亮色感叹号

      UIButtonTypeInfoDark, 暗色感叹号

      UIButtonTypeContactAdd, 十字加号按钮

      } UIButtonType;

      第二、设置frame

      button1.frame = CGRectMake(20, 20, 280, 40);

      [button setFrame:CGRectMake(20,20,50,50)];

      第三、button背景色

      button1.backgroundColor = [UIColor clearColor];

      [button setBackgroundColor:[UIColor blueColor]];

      第四、state状态

      forState: 这个参数的作用是定义按钮的文字或图片在何种状态下才会显现

      enum {

      UIControlStateNormal = 0, 常规状态显现

      UIControlStateHighlighted = 1 << 0, 高亮状态显现

      UIControlStateDisabled = 1 << 1, 禁用的状态才会显现

      UIControlStateSelected = 1 << 2, 选中状态

      UIControlStateApplication = 0x00FF0000, 当应用程序标志时

      UIControlStateReserved = 0xFF000000 为内部框架预留,可以不管

      };

      @property(nonatomic,getter=isEnabled)BOOL enabled; // default is YES. if NO, ignores touch events and subclasses may draw differently

      @property(nonatomic,getter=isSelected)BOOL selected; // default is NO may be used by some subclasses or by application

      @property(nonatomic,getter=isHighlighted)BOOL highlighted;

      第五 、设置button填充图片和背景图片

      [buttonsetImage:[UIImageimageNamed:@"checkmarkControllerIcon"]forState:UIControlStateNormal];

      [buttonsetBackgroundImage:[UIImageimageNamed:@"checkmarkControllerIcon"]forState:UIControlStateNormal];

      第六、设置button标题和标题颜色

      [button1 setTitle:@"点击" forState:UIControlStateNormal];

      [buttonsetTitleColor:[UIColorredColor]forState:UIControlStateNormal];

      第七、设置按钮按下会发光

      button.showsTouchWhenHighlighted=NO;

      第八、添加或删除事件处理

      [button1 addTarget:self action:@selector(butClick:) forControlEvents:UIControlEventTouchUpInside];

      [btn removeTarget:nil action:nil forControlEvents:UIControlEventTouchUpInside];

      第九、 设置按钮内部图片间距和标题间距

      UIEdgeInsets insets; // 设置按钮内部图片间距

      insets.top = insets.bottom = insets.right = insets.left = 10;

      bt.contentEdgeInsets = insets;

      bt.titleEdgeInsets = insets; // 标题间距
