Question

我想在我的SpriteKit游戏中实现一个Textfield输入你的名字，所以我有这样的东西：

SKLabelNode* gameTitle = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"];
gameTitle.text = @"Game Title";
gameTitle.name = @"gametitle";
gameTitle.fontSize = 44.0;
gameTitle.fontColor = [SKColor blackColor];
gameTitle.position = CGPointMake(self.size.width/2,self.size.height/2 + 150);
[self addChild:gameTitle];

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(self.size.width/2, self.size.height/2+20, 200, 40)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.textColor = [UIColor blackColor];
textField.font = [UIFont systemFontOfSize:17.0];
textField.placeholder = @"Enter your name here";
textField.backgroundColor = [SKColor whiteColor];
textField.autocorrectionType = UITextAutocorrectionTypeYes;
textField.keyboardType = UIKeyboardTypeDefault;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.delegate = self.delegate;

[self.view addSubview:textField];

所以，问题是它没有在我的场景中显示，也许问题是当它添加到场景中时，我使用addSubview。

这是错的吗？

Answer 1

您可以在didMoveToView:(SKView *)view函数

中添加继承UIView的对象

只需将该功能添加到SKScene并将UITextField移到内部：

-(void)didMoveToView:(SKView *)view {
    UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(self.size.width/2, self.size.height/2+20, 200, 40)];
    textField.center = self.view.center;
    textField.borderStyle = UITextBorderStyleRoundedRect;
    textField.textColor = [UIColor blackColor];
    textField.font = [UIFont systemFontOfSize:17.0];
    textField.placeholder = @"Enter your name here";
    textField.backgroundColor = [UIColor whiteColor];
    textField.autocorrectionType = UITextAutocorrectionTypeYes;
    textField.keyboardType = UIKeyboardTypeDefault;
    textField.clearButtonMode = UITextFieldViewModeWhileEditing;
    textField.delegate = self.delegate;
    [self.view addSubview:textField];
}

Answer 2

删除它使用

[myTextField removeFromSuperView];

如果你不想使用在场景演示中插入textField的方法didMoveToView，你可以使用这个方法：

-(void)insertUI{

ttaAppDelegate *myDel = [[UIApplication sharedApplication] delegate];
UIViewController *vc = myDel.window.rootViewController;
self.textField= [[UITextField alloc] initWithFrame:CGRectMake(self.size.width/2, self.size.height/2+20, 200, 40)];
self.textField.center = self.view.center;
self.textField.borderStyle = UITextBorderStyleRoundedRect;
self.textField.textColor = [UIColor blackColor];
self.textField.font = [UIFont systemFontOfSize:17.0];
self.textField.placeholder = @"Enter your name here";
self.textField.backgroundColor = [UIColor whiteColor];
self.textField.autocorrectionType = UITextAutocorrectionTypeYes;
self.textField.keyboardType = UIKeyboardTypeDefault;
self.textField.clearButtonMode = UITextFieldViewModeWhileEditing;
self.textField.delegate = self;
self.button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.button addTarget:self action:@selector(saveScore:) forControlEvents:UIControlEventTouchDown];
[self.button setTitle:@"Save" forState:UIControlStateNormal];
self.button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);

[vc.view addSubview:self.textField];
[vc.view addSubview:self.button];
vc.interstitialPresentationPolicy = ADInterstitialPresentationPolicyManual;
[vc requestInterstitialAdPresentation];
}
