我有一个IB名为UIView ButtonHolderView。我在这个视图中添加一个UIButton和动画它。我设置了委托，这样当按下按钮时，我会通知用户。但是，动画完成后，我不能点击按钮。我可以清楚地看到该按钮位于设备和查看调试器的视图中。无法CAKeyFrameAnimation后UIButton的互动与填充模式
以下是截图：
和设备：
动画：
按钮转到左侧，然后去正确的，然后去一个，然后去正确，并停止！
代码：
ViewController.m
地产宣布：
@property (nonatomic,strong) IBOutlet ButtonHolderView *butTopHolder;
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
_butTopHolder.buttonHolderViewDelegate=self;
[_butTopHolder addButtonViewAnimationWithCompletion:^(BOOL finished) {
NSLog(@"completed");
}];
}
，并在ButtonHolderView.m：
- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self)
{
[self setupHierarchy];
}
return self;
}
- (void)setupHierarchy
{
UIView *scaling = [UIView new];
scaling.clipsToBounds=NO; //tried to set NO
scaling.bounds = CGRectMake(0, 0, 320, 568);
scaling.center = CGPointMake(320.0, 568.0);
scaling.layer.masksToBounds = NO; //tried to set NO
[self addSubview:scaling];
UIButton *aboutme = [UIButton buttonWithType:UIButtonTypeCustom];
aboutme.userInteractionEnabled=YES;
aboutme.bounds = CGRectMake(0, 0, 50.0, 50.0);
UIImage *imgAboutme = [UIImage imageWithContentsOfFile:[bundle pathForResource:@"aboutme.png" ofType:nil]];
[aboutme setBackgroundImage:imgAboutme forState:UIControlStateNormal];
aboutme.contentMode = UIViewContentModeCenter;
aboutme.layer.position = CGPointMake(80, 80);
aboutme.alpha = 0.00;
[aboutme addTarget:self action:@selector(actionAboutmePressed:) forControlEvents:UIControlEventTouchUpInside];
[scaling addSubview:aboutme];
}
- (void)addButtonViewAnimationWithCompletion:(void (^)(BOOL finished))completionBlock
{
[self addButtonViewAnimationWithBeginTime:0 andFillMode:kCAFillModeBoth andRemoveOnCompletion:NO completion:completionBlock];
}
- (void)addButtonViewAnimationWithBeginTime:(CFTimeInterval)beginTime andFillMode:(NSString *)fillMode andRemoveOnCompletion:(BOOL)removedOnCompletion completion:(void (^)(BOOL finished))completionBlock
{
CAMediaTimingFunction *linearTiming = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
CAKeyframeAnimation *aboutmeTranslationXAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform.translation.x"];
aboutmeTranslationXAnimation.duration = 1.150;
aboutmeTranslationXAnimation.values = @[@(0.000), @(-130.000), @(100.000), @(-20.000), @(70.000), @(0.000)];
aboutmeTranslationXAnimation.keyTimes = @[@(0.000), @(0.261), @(0.435), @(0.609), @(0.783), @(1.000)];
aboutmeTranslationXAnimation.timingFunctions = @[linearTiming, linearTiming, linearTiming, linearTiming, linearTiming];
aboutmeTranslationXAnimation.beginTime = beginTime;
aboutmeTranslationXAnimation.fillMode = fillMode;
aboutmeTranslationXAnimation.removedOnCompletion = removedOnCompletion;
}
当使用FillMode:kCAFillModeBoth，动画后，我可以看到设备上的按钮，但不能触摸它
当FillMode:kCAFillModeRemoved/Forward/Backward使用，动画后，我不能看到在装置中的按钮，但我可以在视图调试器上看到它！
我尝试设置masksToBounds为NO，但它并没有奏效。
任何人都可以给我建议的方式来解决这个问题？
