我发现了一些类似于我的问题,但我仍然没有得到它。如何获得在另一个类中声明的类对象?
我有第一类加载继承CCScene,比我创建一个对象去UIView类,并使用addChild和比我创建另一个UIView类的对象,并使用addSubView。 所以CCScene - >的UIView - >的UIView
声明所述第一对象的:
startLayer.h:
@interface startLayer : CCScene {
@public
PlayScene *tView;
}
startLayer.m:
tView = [[PlayScene alloc]initWithFrame:CGRectMake(0, 0, 320, 520)];
tView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"backGround.jpg"]];
CCUIViewWrapper* wrapper = [CCUIViewWrapper wrapperForUIView:tView];
[self addChild:wrapper];
第二对象:
PlayScene.h:
@interface PlayScene : UIView {
@public
gameOverMenu* gorm ;
}
PlayScene.m:
gorm = [[gameOverMenu alloc]initWithFrame:CGRectMake(0, 0, 320, 520)];
gorm.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"backGround.jpg"]];
[self addSubview:gorm];
所以在gameOverMenu类我的UITextField子视图:
UITextField* tf = [[UITextField alloc]initWithFrame:CGRectMake(100, 350, 150, 20)];
[tf setPlaceholder:@"Type your name.."];
[self addSubview:tf];
,我想使键盘移动视图,有人告诉我,喜欢写东西这在我的RootViewController:
- (void)viewDidLoad {
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:nil];
}
-(void)keyboardDidShow:(NSNotification*)notification {
NSDictionary* userInfo = [notification userInfo];
NSValue* value = [userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey];
CGSize keyboardSize = [value CGRectValue].size;
// NSLog (@"%@", NSStringFromCGRect(gm.frame));
NSLog(@"%@", gm.superview);
// NSLog(@"%d", [gm.subviews count]);
gm.frame = CGRectMake(gm.frame.origin.x, gm.frame.origin.y, gm.frame.size.width, gm.frame.size.height-keyboardSize.height);
// NSLog (@"%@", NSStringFromCGRect(gm.frame));// NSLog(@"%@", gm.superview);
// NSLog(@"%d", [gm.subviews count]);
}
-(void)keyboarDidHide:(NSNotification*)notification {
NSDictionary* userInfo = [notification userInfo];
NSValue* value = [userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey];
CGSize keyboardSize = [value CGRectValue].size;
gm.frame = CGRectMake(gm.frame.origin.x, gm.frame.origin.y, gm.frame.size.width, gm.frame.size.height+keyboardSize.height);
}
@class gameOverMenu;
@interface RootViewController : UIViewController {
@public
gameOverMenu* gm;
}
但NSLog显示th gm对象没有框架,没有超类,也没有子视图,我想这意味着我应该在这里使用我的表单对象,但我不知道如何从另一个类中获取它。顺便说一句,我创建了cocos2d项目,所以我必须编写[self viewDidLoad];在AppDelegate中,我没有在RootViewController中实现其他方法。
