UIVIew动画在iOS 10中无法正常运行

Question

GIF显示了这个问题。 下面的代码显示了我如何将视图添加到superview并从superview的底部调出。此代码在iOS 9中运行良好，而在iOS 10中运行良好。

上滑动画的动画不合适。它是从右侧出来，而不是直接从底部形成角度。

请帮我解决这个问题。

+ (ControlsView *)addArticleControlsToView:(UIView *)view bellowSubview:(UIView *)subview{
    ControlsView *articleControls = [[[NSBundle mainBundle] loadNibNamed:@"ControlsView" owner:self options:nil]firstObject];
    [view insertSubview:articleControls belowSubview:subview];
    NSDictionary *viewsDict = @{@"currentView":articleControls};
    [articleControls setTranslatesAutoresizingMaskIntoConstraints:NO];
    NSArray *horizontalConstraints = [NSLayoutConstraint constraintsWithVisualFormat:[NSString stringWithFormat:@"H:|-0-[currentView]-0-|"] options:0 metrics:@{} views:viewsDict];
    NSArray *verticalConstraints = [NSLayoutConstraint constraintsWithVisualFormat:@"V:[currentView(189)]-0-|" options:0 metrics:@{} views:viewsDict];
    [view addConstraints:horizontalConstraints];
    [view addConstraints:verticalConstraints];
    [articleControls setBackgroundColor:[UIColor clearColor]];
    articleControls.viewBottomConstraint.constant = -189;
    [articleControls layoutIfNeeded];
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:articleControls action:@selector(slideSheetDown)];
    [articleControls addGestureRecognizer:tapGesture];
    return articleControls;
}

- (void)slideSheetUp {
    [UIView animateWithDuration:0.5 animations:^{
        self.viewBottomConstraint.constant = 0;
        self.scrollViewBottomConstraint.constant = 189;
        [self setBackgroundColor:[UIColor clearColor]];
        [self.scrollView.superview layoutIfNeeded];
        [self layoutIfNeeded];
    }];
}

Answer 1

只需使用此代码

- (void)slideSheetUp {
    self.viewBottomConstraint.constant = 0;
    self.scrollViewBottomConstraint.constant = 189;
    [self setBackgroundColor:[UIColor clearColor]];
    [UIView animateWithDuration:0.5 animations:^{
        [self.scrollView.superview layoutIfNeeded];
        [self layoutIfNeeded];
    }];
}

希望它对你有用。 ;）

快乐的编码!!

适合我。

-(void)hideShowTimerButton:(BOOL)show{

 [UIView animateWithDuration:0.3 animations:^{
    CGRect yourViewFrame =  yourView.frame;
    if(show){
        timeContainerViewFrame.origin.y = self.view.frame.size.height;
    }else{
        timeContainerViewFrame.origin.y = self.view.frame.size.height - yourViewFrame.size.height;
    }
    yourView.frame = yourViewFrame;
} completion:^(BOOL finished) {
}];

}

请重新安排你的代码如下，它没有影响我的视图动画太多，并解决了我的问题。谢谢你们。

- (void)slideSheetUp {
    self.viewBottomConstraint.constant = 0;
    [self setBackgroundColor:[UIColor clearColor]];
    [UIView animateWithDuration:0.5 animations:^{
        [self layoutIfNeeded];
    } completion:^(BOOL finished) {
        self.scrollViewBottomConstraint.constant = 189;
        [self.scrollView.superview layoutIfNeeded];
    }];
}
