SIGABRT 消息仅适用于 iOS5

发布于 2024-12-10 15:16:33 字数 2256 浏览 2 评论 0原文

我的应用程序遇到了奇怪的崩溃，这种情况只发生在 iOS5 上。问题似乎出在我的核心动画方法上，因为当我没有为 aAnimation.repeatCount 或 0 设置任何值时，它正在工作，但是当它旋转时，我使用 get SIGABRT 消息，但出现错误：-[NSConcreteValue doubleValue]：无法识别的选择器发送到当我触摸设备/模拟器屏幕时，实例 0x9628100。

任何帮助将不胜感激

我的视图定义

- (void)loadView {
    CGRect screenRect = [[UIScreen mainScreen] applicationFrame];

    UIView  *contentView = [[UIView alloc] initWithFrame:screenRect];
    contentView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

    self.view = contentView;
    [contentView release];
}

设置子视图子

- (void)setUpPlacardView:(NSInteger)picture {
    // Create the placard view -- its init method calculates its frame based on its image
    PlacardView *aPlacardView = [[PlacardView alloc] init:picture asColor:asColor];
    aPlacardView.desaturation = kotucHue;
    self.placardView = aPlacardView;
    [aPlacardView release];
    [self.view addSubview:placardView];
}

视图定义

@interface PlacardView : UIView {


    UIImage                 *placardImage;
    float                   saturation;
    UIColor                 *barva;
    BOOL                    switchMode;



}

@property (nonatomic, retain) UIImage *placardImage;
@property (nonatomic)       float     desaturation;
@property (readwrite) BOOL              switchMode;


// Initializer for this object
- (id)init:(NSInteger)picture asColor:(BOOL)farba;


@end

并进行旋转

- (void)makeKspinning
{
    // Create a transform to rotate in the z-axis
    float radians = 3.120;   
    CATransform3D transform;
    if (rotation) {
        transform = CATransform3DMakeRotation(radians, 0.0, 0.0, 0.0);
    }
    else
        transform = CATransform3DMakeRotation(radians, 0.0, 0.0, 1.0);


    CABasicAnimation *aAnimation;
    aAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];

        CALayer *pLayer = placardView.layer;

        aAnimation.toValue = [NSValue valueWithCATransform3D:transform];
        aAnimation.duration = spinSpeed;
        aAnimation.cumulative = YES;
        aAnimation.repeatCount = HUGE_VALF; 

        [pLayer addAnimation:aAnimation forKey:@"animatePlacardViewToSpin"];

        pLayer.opacity = spinOpacity;
}

原文

I'm facing a strange crash of my app that occurs only with iOS5. The problem seems to be with my core animation method bellow, because when I set no value for aAnimation.repeatCount or 0 it is working, but when it rotates I use get SIGABRT message with error: -[NSConcreteValue doubleValue]: unrecognized selector sent to instance 0x9628100 when I touch device/simulator screen.

any help will be appreciated

My view definition

- (void)loadView {
    CGRect screenRect = [[UIScreen mainScreen] applicationFrame];

    UIView  *contentView = [[UIView alloc] initWithFrame:screenRect];
    contentView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

    self.view = contentView;
    [contentView release];
}

setting a subView

- (void)setUpPlacardView:(NSInteger)picture {
    // Create the placard view -- its init method calculates its frame based on its image
    PlacardView *aPlacardView = [[PlacardView alloc] init:picture asColor:asColor];
    aPlacardView.desaturation = kotucHue;
    self.placardView = aPlacardView;
    [aPlacardView release];
    [self.view addSubview:placardView];
}

SubView definition

@interface PlacardView : UIView {


    UIImage                 *placardImage;
    float                   saturation;
    UIColor                 *barva;
    BOOL                    switchMode;



}

@property (nonatomic, retain) UIImage *placardImage;
@property (nonatomic)       float     desaturation;
@property (readwrite) BOOL              switchMode;


// Initializer for this object
- (id)init:(NSInteger)picture asColor:(BOOL)farba;


@end

and make rotation


- (void)makeKspinning
{
    // Create a transform to rotate in the z-axis
    float radians = 3.120;   
    CATransform3D transform;
    if (rotation) {
        transform = CATransform3DMakeRotation(radians, 0.0, 0.0, 0.0);
    }
    else
        transform = CATransform3DMakeRotation(radians, 0.0, 0.0, 1.0);


    CABasicAnimation *aAnimation;
    aAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];

        CALayer *pLayer = placardView.layer;

        aAnimation.toValue = [NSValue valueWithCATransform3D:transform];
        aAnimation.duration = spinSpeed;
        aAnimation.cumulative = YES;
        aAnimation.repeatCount = HUGE_VALF; 

        [pLayer addAnimation:aAnimation forKey:@"animatePlacardViewToSpin"];

        pLayer.opacity = spinOpacity;
}

我认为问题是您将 toValue 设置为 NSValue，但关键路径是 transform.rotation，这不是一个 NSValue。您应该使用 transform 作为 keyPath，或者应该使用 transform.rotation.z （或任何轴）作为 keyPath 和一个简单的 NSNumber< /code> 作为您的值。
