如何在横向模式下从底部滑入 UIView

Question

我已将 UIView 添加到 IB 上的另一个“主”视图。我的应用程序仅处于横向模式。我想让它通过按下一个按钮，这个另一个 UIView 从底部滑入。所以，目前它根本不在图片中，但是当按下按钮时，视图会从底部出现并滑入到位。稍后我将使用相同的按钮作为切换按钮，然后将 UIVIew 滑出。 UIView 不是屏幕的大小，否则我会以模态方式呈现它。

这是我尝试过的代码：

.m

-(IBAction)onGearBag:(UIButton *)sender
{

    [sender setEnabled:NO];
    [UIView animateWithDuration:0.5 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
        if (gearBag.transform.ty == 0) {
            [gearBag setTransform:CGAffineTransformMakeTranslation(0, -400)];
        }else{
            [gearBag setTransform:CGAffineTransformMakeTranslation(0, -200)];
        }
    }completion:^(BOOL done){
        //some completion handler
        [sender setEnabled:YES];
    }];
}

.h

@interface MyEquipmentViewController : PFViewController
{
    IBOutlet UIView *gearBag;
}
@property (strong, nonatomic) TabsTopBar *topbar;
- (IBAction)onPopoverButton:(UIButton *)sender;
- (IBAction)actionHelp:(id)sender;
- (IBAction)onGearBag:(id)sender;
@end

.h

@interface MyEquipmentViewController : PFViewController
{
    IBOutlet UIView *popoverInitAlert;
    __unsafe_unretained IBOutlet UIImageView *imageView;
    IBOutlet UIView *gearBag;
}

@property (strong, nonatomic) TabsTopBar *topbar;
- (IBAction)onPopoverButton:(UIButton *)sender;
- (IBAction)actionHelp:(id)sender;
- (IBAction)onGearBag:(id)sender;
@end

简单的视图动画：

- (IBAction)myIBAction:(UIButton *)sender
{
    [sender setEnabled:NO];
    [UIView animateWithDuration:0.5 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
        if (mySecondView.transform.ty == 0) {
            [mySecondView setTransform:CGAffineTransformMakeTranslation(0, -400)];
        }else{
            [mySecondView setTransform:CGAffineTransformMakeTranslation(0, 0)];
        }
    }completion:^(BOOL done){
        //some completion handler
        [sender setEnabled:YES];
    }];
}
