Objective c CGFloat中的错误消息

我是记分板应用程序，我不需要在点击按钮时添加UItextfield和标签。我在这些方法中不断出现错误。有什么建议吗

错误消息： “从不兼容的类型'double'分配到'UIView*'”

错误消息： “从不兼容的类型'UIView*'分配'CGFloat'（也称为'float'）”

错误消息： “二进制表达式（'UIView*'和'CGFloat'（也称为'float'）的操作数无效”

代码如下：

-(void)addPlayerTapped:(id)sender {

    NSLog(@"Adding Player");
    self.yOffset = 60.0;

    UIViewController *llVC = [[DetailViewController alloc] init];
    llVC.view.alpha = 0.0;
    [self.playersArray addObject:llVC];
    [self.view addSubview:llVC.view];

    [self repositionFields];
}

-(void)repositionFields {

    // Reposition each view in the array
    for (DetailViewController *llVC in self.playersArray) {
        CGRect frame = llVC.view.frame;
        frame.origin.x = 15;
        frame.origin.y = self.yOffset;
        llVC.view.frame = frame;
        self.yOffset += frame.size.height;
    }

    // Add some animations to make it look nice
    [UIView animateWithDuration:0.3 animations:^{
        CGRect frame = self.addPlayerButton.frame;
        frame.origin.y = self.yOffset;
        self.addPlayerButton.frame = frame;
    } completion:^(BOOL finished) {
        DetailViewController *llVC = [self.playersArray lastObject];
        llVC.view.alpha = 1.0;
    }];
}

从错误消息判断，您似乎将

yOffset

声明为

UIView*

而不是

CGFloat

，例如

@property (assign, nonatomic) UIView *yOffset; 

然而它应该是

@property (assign, nonatomic) CGFloat yOffset;

如何声明

yOffset

？@属性（赋值，非原子）CGFloat*yOffset；这应该是

CGFloat yOffset

，而不是

CGFloat*yOffset

-您不希望它是指针。请发布实际代码和错误消息。你发布的那篇文章清楚地表明，你将其声明为

@property（assign，非原子）UIView*yOffset。这是我收到的错误消息。
-(void)addPlayerTapped:(id)sender {

    NSLog(@"Adding Player");
    self.yOffset = 60.0;

    UIViewController *llVC = [[DetailViewController alloc] init];
    llVC.view.alpha = 0.0;
    [self.playersArray addObject:llVC];
    [self.view addSubview:llVC.view];

    [self repositionFields];
}

-(void)repositionFields {

    // Reposition each view in the array
    for (DetailViewController *llVC in self.playersArray) {
        CGRect frame = llVC.view.frame;
        frame.origin.x = 15;
        frame.origin.y = self.yOffset;
        llVC.view.frame = frame;
        self.yOffset += frame.size.height;
    }

    // Add some animations to make it look nice
    [UIView animateWithDuration:0.3 animations:^{
        CGRect frame = self.addPlayerButton.frame;
        frame.origin.y = self.yOffset;
        self.addPlayerButton.frame = frame;
    } completion:^(BOOL finished) {
        DetailViewController *llVC = [self.playersArray lastObject];
        llVC.view.alpha = 1.0;
    }];
}

@property (assign, nonatomic) UIView *yOffset; 

@property (assign, nonatomic) CGFloat yOffset;
