我想使settingView
在myView
顯示並隨動畫消失。
我致電-showSettingView
if (!self.settingView)
:動畫正常工作。
但是,else if (self.myView)
:settingView
沒有動畫就消失了。
如何修復它使settingView
隨動畫消失?UIView動畫不起作用
@property (nonatomic, strong) UIView *myView;
@property (nonatomic, strong) UIView *settingView;
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem* settingButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(showSettingView)];
self.navigationItem.rightBarButtonItem = settingButton;
}
- (void)showSettingView
{
self.myView = [[UIView alloc]initWithFrame:CGRectMake(0, 568, 320, 480)];
self.myView.opaque = NO;
self.myView.backgroundColor = [UIColor colorWithWhite:1.0f alpha:0.0f];
[self.view addSubview:self.myView];
if (!self.settingView) {
self.settingView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];
self.settingView.backgroundColor = [UIColor blackColor];
[self.myView addSubview:self.settingView];
[UIView animateWithDuration:0.3f
delay:0.0f
options:UIViewAnimationOptionTransitionFlipFromBottom
animations:^{self.myView.frame = CGRectMake(0, 60, 320, 480);}
completion:^(BOOL finished) {}
];
} else if (self.myView){
self.myView.frame = CGRectMake(0, 60, 320, 480);
[UIView animateWithDuration:0.3f
delay:0.0f
options:UIViewAnimationOptionCurveEaseIn
animations:^{self.myView.frame = CGRectMake(0, 568, 320, 480);}
completion:^(BOOL finished) {}
];
[self.settingView removeFromSuperview];
self.settingView = nil;
[self.myView removeFromSuperview];
}
}
謝謝。
