我试图在同一个ViewController上翻转过渡，我有一个触发转换按钮。当我通过翻转过渡按下按钮时，我想更改主题颜色。
我使用了这段代码：
- (IBAction)changeThemeButtonTapped:(id)sender
{
int tempThemeColor = [[NSUserDefaults standardUserDefaults]integerForKey:@"themeColor"];
if (tempThemeColor == 10) {
[self loadTheme];
[UIView transitionFromView:self.view
toView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
completion:^(BOOL finished) {
NSLog(@"finished");
}];
}else{
[self loadTheme];
[UIView transitionFromView:self.view
toView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromRight
completion:^(BOOL finished) {
NSLog(@"finished");
}];
}
}
当我按下按钮时，视图变为黑色。有什么办法吗？我的错是什么？ 感谢您的回答和兴趣。

我找到了问题的答案。
if (tempThemeColor == 10) {
[self loadTheme];
[UIView transitionWithView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
} completion:^(BOOL finished) {
}];
}else{
[self loadTheme];
[UIView transitionWithView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^{
} completion:^(BOOL finished) {
}];
}

在做动画之前，尝试更改视图颜色的窗口/超级视图
if (self.view.superview) {
self.view.superview.backgroundColor = [UIColor whiteColor];
}
self.view.window.backgroundColor = [UIColor whiteColor];
