Question

我有这个代码设置一些标签，隐藏和其他几个，然后删除我从屏幕上制作的自定义加载视图，这是代码：

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];

但加载视图首先消失，然后几秒后标签出现/消失，这取决于我设置的内容，为什么加载视图首先消失，当它位于代码的底部时？

感谢您的帮助：）

以下是我如何调用加载视图：

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)];

这是加载视图的.m

我现在正在做这个

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];
});

仍然无法正常工作？

如果您在viewDidLoad中执行上述所有设置，请尝试移动隐藏功能 viewDidAppear。

所以

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

将UILabel设置为隐藏
