ios - 将 UILabel 设置为隐藏

Question

我有这段代码，它设置了一些标签，隐藏了一些标签，然后删除了我从屏幕上制作的自定义加载 View ，这里是代码:

self.yourPlanLabel.text = [infoArray objectAtIndex:0];
self.yourMealLabel.text = [infoArray objectAtIndex:1];
self.yourBalanceLabel.text = [infoArray objectAtIndex:2];
self.usernameField.hidden = YES;
self.passwordField.hidden = YES;
self.loginBtn.hidden = YES;
self.yourPlanLabel.hidden = NO;
self.yourMealLabel.hidden = NO;
self.yourBalanceLabel.hidden = NO;
//remove loading view
[self.loadingView removeFromSuperview];

但是加载 View 首先消失，然后几秒钟后标 checkout 现/消失，具体取决于我设置的内容，为什么加载 View 在代码底部时首先消失？

谢谢您的帮助 :)

这是我如何调用加载 View :

self.loadingView = [[LoadingView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:self.loadingView];
[self.navigationController.view addSubview:self.loadingView];
[self.loadingView setCenter:CGPointMake(self.view.frame.size.width / 2, self.view.frame.size.height / 2 +32)];

这是加载 View 的 .m

我现在正在这样做

dispatch_async(dispatch_get_main_queue(), ^{
    self.yourPlanLabel.text = [infoArray objectAtIndex:0];
    self.yourMealLabel.text = [infoArray objectAtIndex:1];
    self.yourBalanceLabel.text = [infoArray objectAtIndex:2];

    self.usernameField.hidden = YES;
    self.passwordField.hidden = YES;
    self.loginBtn.hidden = YES;

    self.mealLabel.hidden = NO;
    self.planLabel.hidden = NO;
    self.balanceLabel.hidden = NO;
    self.yourPlanLabel.hidden = NO;
    self.yourMealLabel.hidden = NO;
    self.yourBalanceLabel.hidden = NO;
    self.loadingView.hidden = YES;
    [self.loadingView removeFromSuperview];
});

而且还是不行？

Answer 1

如果你在 viewDidLoad 中做以上所有设置，请尝试将隐藏功能移入
viewDidAppear。

所以这是

-(void)viewDidAppear
{
        [self.loadingView removeFromSuperview];
}
