在uiscrollview中創建一個uisegmentedcontrol

Question

我想要使用非常大的分段控件組件，所以我的想法是通過水平滾動來使其在uiscrollview ..so中可以選擇適當的項目。 我寫了這個代碼：

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]; 

但滾動視圖沒有讓segmentedcontrol待觀察。 我的錯誤在哪裏？

Answer 1

也許這將幫助你：

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];

您可以使用UICollectionView，水平滾動使用的按鈕小區。
