我有这段代码：
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 170, 320, 260)];
scrollView.contentSize = CGSizeMake(960, 240);
[scrollView setPagingEnabled:YES];
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.delegate = self;
[scrollView setBackgroundColor:[UIColor redColor]];
[self.view addSubview:scrollView];
graphView = [[FDGraphView alloc] initWithFrame:CGRectMake(0, 10, 320, 240)];
[graphView setLinesColor:[UIColor whiteColor]];
[graphView setDataPointColor:[UIColor clearColor]];
[graphView setDataPointStrokeColor:[UIColor grayColor]];
[graphView setBackgroundColor:[UIColor greenColor]];
[scrollView addSubview:graphView];
我希望看到这个：
但相反，我看到了这个：
我只使用 uiview 和上面的代码，使用可可控件 FDGraphView （顺便说一句很棒），我得到了一个新项目的预期，我得到了奇怪的行为。
FDGraphView 是 UIView 子类，但也使用 UIScrollView 并且在添加为 viewController 视图的子视图时正常工作，
有任何想法吗？？
编辑：显然下面代码中的某些内容导致了问题
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
// resize your layers based on the view’s new bounds
[[[self.view.layer sublayers] objectAtIndex:0] setFrame:self.view.bounds];
if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
[graphView setFrame:CGRectMake(0, 150, 480, 150)];
[graphView setNeedsDisplay];
[refresh setFrame:CGRectMake(5, 305, 10, 10)];
CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
if (screenRect.size.height == 568)
{
//if iPhone 5+
NSLog(@"iPhone 5+ Detected");
[graphView setFrame:CGRectMake(0, 150, 568, 150)];
[graphView setNeedsDisplay];
}
}
if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
{
[graphView setFrame:CGRectMake(0, 170, 320, 240)];
[graphView setNeedsDisplay];
[refresh setFrame:CGRectMake(5, 465, 10, 10)];
CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
if (screenRect.size.height == 568)
{
//if iPhone 5+
NSLog(@"iPhone 5+ Detected");
[graphView setFrame:CGRectMake(0, 170, 320, 240)];
[graphView setNeedsDisplay];
[refresh setFrame:CGRectMake(5, 553, 10, 10)];
}
}
if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
[graphView setFrame:CGRectMake(0, 150, 480, 150)];
[graphView setNeedsDisplay];
[refresh setFrame:CGRectMake(5, 305, 10, 10)];
CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
if (screenRect.size.height == 568)
{
//if iPhone 5+
NSLog(@"iPhone 5+ Detected");
[graphView setFrame:CGRectMake(0, 150, 568, 150)];
[graphView setNeedsDisplay];
}
}
}
- (void)viewDidAppear:(BOOL)animated
{
[self willAnimateRotationToInterfaceOrientation:[[UIApplication sharedApplication] statusBarOrientation] duration:0.5 ];
}
