在.h中聲明屬性如下
@property (retain, nonatomic) UIWindow *window;
@property (nonatomic, retain) UIView *aView;
@property (nonatomic, retain) UIButton *button;
在.m中實現如下
@implementation MAYAppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
{ self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
_aView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 568)];
_aView.backgroundColor = [UIColor lightGrayColor];
[self.window addSubview:_aView];
[_aView release];
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 5; j++) {
_button = [[UIButton alloc] initWithFrame:CGRectMake(15 + 60 * j , 50 + 60 *i, 50, 50)];
_button.adjustsImageWhenHighlighted = NO;
[_button setBackgroundImage:[UIImage imageNamed:@"8.png"] forState:UIControlStateNormal];
[_button setBackgroundImage:[UIImage imageNamed:@"2.png"] forState:UIControlStateSelected];
[_button addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
_button.tag = 120 + 10 * i + j;
[_aView addSubview:_button];
[_button release];
}
}
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
- (void)click:(UIButton *)btn
{
btn.selected = !btn.selected;
UIButton *upButton = (UIButton *)[_aView viewWithTag:btn.tag - 10];
upButton.selected = !upButton.selected;
UIButton *downButton = (UIButton *)[_aView viewWithTag:btn.tag + 10];
downButton.selected = !downButton.selected;
UIButton *leftButton = (UIButton *)[_aView viewWithTag:btn.tag - 1];
leftButton.selected = !leftButton.selected;
UIButton *rightButton = (UIButton *)[_aView viewWithTag:btn.tag + 1];
rightButton.selected = !rightButton.selected;
}
