在 uiscrollview 中制作 uisegmentedcontrol

我想使用一个非常大的分段控制组件，所以我有想法将其制作在 uiscrollview 中。这样通过水平滚动，用户可以选择适当的项目。我写了这段代码：

CGRect rect = [[UIScreen mainScreen] applicationFrame];
CGRect frame = CGRectMake(rect.origin.x + kLeftMargin, rect.size.height - kPaletteHeight - kTopMargin, 2*rect.size.width , kPaletteHeight);
seg.frame = frame;

scroll.frame = frame;
scroll.contentSize = CGSizeMake(frame.size.width * 2,frame.size.height);
scroll.showsHorizontalScrollIndicator = YES;
scroll.showsVerticalScrollIndicator = NO;
scroll.scrollsToTop = NO;
[scroll addSubview:seg];

但是滚动视图没有让分段控件被看到。我的错误在哪里？

I want to use a very large segmentedcontrol component so I had the idea to make it in a uiscrollview ..so by scrolling horizontally user can choose the appropriate item.
I wrote this code:

CGRect rect = [[UIScreen mainScreen] applicationFrame];
CGRect frame = CGRectMake(rect.origin.x + kLeftMargin, rect.size.height - kPaletteHeight - kTopMargin, 2*rect.size.width , kPaletteHeight);
seg.frame = frame;

scroll.frame = frame;
scroll.contentSize = CGSizeMake(frame.size.width * 2,frame.size.height);
scroll.showsHorizontalScrollIndicator = YES;
scroll.showsVerticalScrollIndicator = NO;
scroll.scrollsToTop = NO;
[scroll addSubview:seg];

but the scroll view didn't let the segmentedcontrol to be seen.
where was my mistake?

也许这会对您有所帮助：

UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 435)];
 scroll.contentSize = CGSizeMake(320, 700);
 scroll.showsHorizontalScrollIndicator = YES;

 NSArray *itemArray = [NSArray arrayWithObjects: @"One", @"Two", @"Three", nil];
 UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
 segmentedControl.frame = CGRectMake(35, 200, 250, 50);
 segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
 segmentedControl.selectedSegmentIndex = 1;

 [scroll addSubview:segmentedControl];
 [segmentedControl release]; 
 [self.view addSubview:scroll];

Maybe this will help you:

UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 435)];
 scroll.contentSize = CGSizeMake(320, 700);
 scroll.showsHorizontalScrollIndicator = YES;

 NSArray *itemArray = [NSArray arrayWithObjects: @"One", @"Two", @"Three", nil];
 UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
 segmentedControl.frame = CGRectMake(35, 200, 250, 50);
 segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
 segmentedControl.selectedSegmentIndex = 1;

 [scroll addSubview:segmentedControl];
 [segmentedControl release]; 
 [self.view addSubview:scroll];
