• iphone 实现九宫格效果


    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 );

    }
