我有一个 UIScrollview 加载良好，显示良好，一切都很好。然后我推送另一个视图控制器，称之为 VC2，它也可以正常工作。从 VC2 我弹出回到 UIScrollview，这是奇怪的行为......当 UIScrollview 回来时，从顶部开始的第一个（我猜）300 像素被切断。如果我拉下页面，我仍然可以看到内容，但显然这对我不起作用。有人有什么想法吗？
这是代码：
这是创建 ScrollView：
-(IBAction)startNewSearch:(id)sender
{
NewSearch *VCscrollView = [[NewSearch alloc] init];
[[self navigationController] pushViewController:VCscrollView animated:YES];
}
滚动视图
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
scrollView.contentSize = CGSizeMake(320, 890);
[scrollView setContentOffset:CGPointMake(0, 0) animated:NO];
[scrollView flashScrollIndicators];
}
-(void)viewWillAppear:(BOOL)animated
{
scrollView.frame = CGRectMake(0, 0, 320, 890);
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
从 ScrollView 中调用 VC2 的 IBAction：
-(IBAction)previewSearch:(id)sender
{
VCcontactServer *VC2 = [[VCcontactServer alloc] init];
[[self navigationController] pushViewController:VC2 animated:YES];
}
