    [super viewdidload];
    //按钮
    uibutton *button = [uibutton buttonwithtype:uibuttontypecustom];
    button.backgroundcolor = [uicolor greencolor];
    [self.view addsubview:button];

    //按钮指定位置
    button.frame = cgrectmake(10, 100, 350, 300);
    //设置按钮上的文字
    [button settitle:@"淘宝" forstate:uicontrolstatenormal];
    //设置字体颜色
    [button settitlecolor:[uicolor orangecolor] forstate:uicontrolstatenormal];

    //背景图片
    //创建一张图片
    //uiimage *image = [uiimage imagenamed:@"淘宝.jpeg"];//jpg不用写格式
    //[button setbackgroundimage:image forstate:uicontrolstatenormal];
    //前景图片
    [button setimage:[uiimage imagenamed:@"淘宝.jpeg"] forstate:uicontrolstatenormal];

    //调整文字和图片的位置
    [button setimageedgeinsets:uiedgeinsetsmake(0, 0, 0, 50)];
    [button settitleedgeinsets:uiedgeinsetsmake(0, 20, 0, 0)];

    //添加点击事件
    [button addtarget:self action:@selector(youtouchme)forcontrolevents:uicontroleventtouchupinside];
}
//实现按钮的点击方法
-(void)youtouchme
