  • IOS-button属性edge

    IOS中UIButton 的内容,标题,背景在button容器的相对位子的设置

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];//button的类型
        button.frame = CGRectMake(100, 100,90, 90);//button的frame
        button.backgroundColor = [UIColor cyanColor];//button的背景颜色
        //    [button setBackgroundImage:[UIImage imageNamed:@"man_64.png"] forState:UIControlStateNormal];
        //    在UIButton中有三个对EdgeInsets的设置:ContentEdgeInsets、titleEdgeInsets、imageEdgeInsets
        [button setImage:[UIImage imageNamed:@"IconHome@2x.png"] forState:UIControlStateNormal];//给button添加image
        button.imageEdgeInsets = UIEdgeInsetsMake(5,13,21,button.titleLabel.bounds.size.width);//设置image在button上的位置(上top,左left,下bottom,右right)这里可以写负值,对上写-5,那么image就象上移动5个像素
        [button setTitle:@"首页" forState:UIControlStateNormal];//设置button的title
        button.titleLabel.font = [UIFont systemFontOfSize:16];//title字体大小
        button.titleLabel.textAlignment = NSTextAlignmentCenter;//设置title的字体居中
        [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];//设置title在一般情况下为白色字体
        [button setTitleColor:[UIColor grayColor] forState:UIControlStateHighlighted];//设置title在button被选中情况下为灰色字体
        button.titleEdgeInsets = UIEdgeInsetsMake(71, -button.titleLabel.bounds.size.width-50, 0, 0);//设置title在button上的位置(上top,左left,下bottom,右right)
        //    [button setContentEdgeInsets:UIEdgeInsetsMake(70, 0, 0, 0)];//
        //   button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;//设置button的内容横向居中。。设置content是title和image一起变化
        
        [button addTarget:self action:@selector(tap) forControlEvents:UIControlEventTouchUpInside];
        [self.view addSubview:button];
