如何显示superview的子视图？

Question

如何实现代码在3秒后自动显示超级视图的子视图而不点击iPhone中的任何按钮？

Answer 1

 NSTimer *t = [NSTimer scheduledTimerWithTimeInterval: 3
                                                      target: self
                                                    selector:@selector(showSuperView)
                                                    userInfo: nil repeats:NO];

如果你想显示childview的超级视图那么

-(void)showSuperView
{
[childView superview].hidden = NO;
}

如果你想显示superview的childView那么

-(void)showchildView
    {
    for([UiView* v in superview.subviews])
{
//implement the condition to identify concerned childView
v.hidden = NO;
}
    }

Answer 2

NSDate *current=[[[NSDate alloc] init] autorelease];
NSTimer *timer=[[NSTimer alloc] initWithFireDate:current interval:3.0 target:self selector:@selector(gotoNextView) userInfo:nil repeats:NO]autoreleas];

- (IBAction) gotoNextView 
{
    yourNextView *obj=[[[yourNextView alloc] initWithNibName:@"yourNextView" bundle:nil]autorelease];
    [self.navigationController pushViewController:obj animated:YES];
}

希望这有用！:)
