第一次用博客，早就想记录我的ios学习历程了，以后也有个留恋吧，由于本人还处于学习阶段，若有哪位高人无意浏览到，不足和错误支出还请多多指教，谢谢！

 

       那么首先就从最常用的UIButton开始吧：

 

UIButton

“ViewController.m”

UIButton *saveButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];

        saveButton.frame=CGRectMake(self.view.frame.size.width-120, self.view.frame.size.height-170, 80, 40);

        [saveButton setTitle:@"保存" forState:UIControlStateNormal];

        [saveButton setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];

        saveButton.backgroundColor=[UIColor blueColor];

        //设置按钮上内容各个方向上偏移量

        saveButton.contentEdgeInsets=UIEdgeInsetsMake(0, 0, 0, 0);

       

        //按下按钮会发光

        saveButton.showsTouchWhenHighlighted=YES;

        //设置内部图片按钮间距

        UIEdgeInsets insets;

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

        saveButton.contentEdgeInsets=insets;

        saveButton.titleEdgeInsets=insets;//标题间距

        //设置按钮边框宽度及颜色

        saveButton.layer.borderWidth=1.0;

        saveButton.layer.borderColor=[[UIColor redColor]CGColor];

        saveButton.layer.cornerRadius=20;//设置按钮矩形四个圆角半径

        //添加点击事件

        [saveButton addTarget:self action:@selector(saveTap) forControlEvents:UIControlEventTouchUpInside];

        [self.view addSubview:saveButton];
