//创建UIButton
UIButton *tmpButton =[[[UIButton alloc] init]autorelease];

[tmpButton setTitle:@"MyButton" forState:UIControlStateNormal];

//设置标题文本的颜色
[tmpButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

//设置图片
UIImage *image3=[UIImage imageNamed:@"a3.png"];
[tmpButton setImage:image3 forState:UIControlStateNormal];

//设置位置和大小
tmpButton.frame = CGRectMake(0, 0, 200, 0);//在这里仅Width有效
