上面的是就功能的实现效果图 当然，能在布局上不是很完美，但是在功能上已经是OK了，这也是根据别人的实现我自己实现了一下的。
具体的代码如下：
- (void)viewDidLoad
{
[superviewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIImageView * contentView = [[UIImageViewalloc] initWithFrame:[[UIScreenmainScreen] applicationFrame]];
[contentView setImage:[UIImage imageNamed:@"bg.png"]];
[contentView setUserInteractionEnabled:YES];
self.view = contentView;
[contentView release];
int index = 0;
UIButton * button;
NSArray * array = [NSArrayarrayWithObjects: @"1.png",@"2.png",@"3.png",@"4.png",@"5.png",@"6.png",@"7.png",@"8.png",@"9.png",nil];
for(index = 0; index < [array count]; ++ index )
{
CGRect frame;
button = [[UIButtonbuttonWithType:UIButtonTypeCustom] retain];
[button setImage:[UIImageimageNamed:[array objectAtIndex:index]] forState:UIControlStateNormal];
button.tag = index;
frame.size.width = 90;
frame.size.height = 90;
frame.origin.x = (index % 3 ) * 90 + 25;
frame.origin.y = floor(index / 3 ) * 90 + 95;
[button setFrame:frame];
[button setBackgroundColor:[UIColorclearColor]];
[button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
[button release];
}
}
-(void)buttonPressed:(id)sender
{
UIButton * button = (UIButton * )sender;
NSLog(@"button index:%d" , button.tag );
}
