如何自动更改/从一个视图转换到另一个视图,无需按下按钮或任何操作,只需一段时间后,在Xcode / Objective-C中说2,3秒,代码将如何显示,以及在何处写吧?

基本解决方案可能如下所示:
- (void)viewDidLoad
{
[super viewDidLoad];
// create and position the subviews, if necessary
self.subview1 = ...
self.subview2 = ...
self.view addSubview:self.subview1];
self.view addSubview:self.subview2];
}
- (void)viewWillAppear
{
[super viewWillAppear];
[self showFirstView];
}
- (void)showFirstView
{
self.subview1.hidden = NO;
self.subview2.hidden = YES;
[self performSelector:@selector(showSecondViewView) withObject:nil afterDelay:5];
}
- (void)showSecondViewView
{
self.subview1.hidden = YES;
self.subview2.hidden = NO;
}
