我正在制作一款由4款迷你游戏组成的iPhone游戏。每个迷你游戏都是一个独立的xib。每场比赛都有自己的菜单和比赛级别。你进入主菜单并选择你想要加载的游戏。如何通过重用单个viewcontroller并处理内存警告来加载xibs?
这就是我目前正在加载每个xib。
MainGameViewController.h
@interface MainGameViewController : UIViewController {
UIViewController *currentView;
int currentViewId;
}
@property (nonatomic, retain) UIViewController *currentView;
- (void)displayView:(int)intNewView;
@end
MainGameViewController.m
@implementation MainGameViewController
@synthesize currentView;
- (void)viewDidLoad {
[super viewDidLoad];
currentView = [[LogoScreen alloc] init];
[self.view addSubview:currentView.view];
}
- (void)displayView :(int)intNewView
{
currentViewId = intNewView;
currentView = nil;
[currentView release];
switch (intNewView) {
case SCR_GAME1:
currentView = [[Game1View alloc] init];
break;
case SCR_GAME1LEVEL:
currentView = [[Game1LevelView alloc] init];
break;
case SCR_GAME2:
currentView = [[Game2View alloc] init];
break;
case SCR_GAME2LEVEL:
currentView = [[Game2LevelView alloc] init];
break;
case SCR_GAME3:
currentView = [[Game3View alloc] init];
break;
case SCR_GAME3LEVEL:
currentView = [[Game3LevelView alloc] init];
break;
case SCR_GAME4:
currentView = [[Game4View alloc] init];
break;
case SCR_GAME4LEVEL:
currentView = [[Game4LevelView alloc] init];
break;
default:
currentView = [[MainView alloc] init];
break;
}
[self.view addSubview:currentView.view];
}
- (void)dealloc {
[currentView release];
currentView = nil;
[super dealloc];
}
@end
这是水平的启动方式。 Game1View.m
@implementation Game1View
-init {
if (self == [super init]) {
MainGameAppDelegate *appdelegate = [[UIApplication sharedApplication] delegate];
isSoundOn = (appdelegate.gvar.soundstate == 1);
gamestate = GAME_STATUS_START;
}
return self;
}
...
...
- (void)launchgame {
MainGameAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
appDelegate.gvar.currentId = objectid;
[appDelegate displayView:SCR_GAME1LEVEL_GAME];
}
- (void)returnToMain {
MainGameAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate displayView:SCR_MAIN];
}
@end
MainGameAppDelegate.m
@implementation MainGameAppDelegate
@synthesize window;
@synthesize viewController;
- (void) displayView:(int)intNewView {
[viewController displayView:intNewView];
}
@end
目前我得到内存警告,当我把意见,然后应用程序崩溃之间的切换。 我的问题是,这是加载这些视图的正确方法吗?我已经发布了我在游戏寿命期间分配的所有内容,而现在我正在为记忆力耗尽而感到茫然。任何帮助将非常感激。
感谢您的快速回复。我认为你的意思是[currentView.view removeFromSuperview];但如果我在[currentView发布]之前添加; 它会导致我的一个xib在释放时有一个EXC_BAD_ACCESS。 – hreaper 2012-03-19 05:15:55
由于您之前已添加子视图,因此必须通过removeFromSuperview删除视图是正常的。尝试启用XCode的僵尸来查看额外版本的发生位置。 – futureelite7 2012-03-19 05:27:04
