Objective c 具有2个视图的UIScrollView分页
我尝试使用本教程中的两个视图实现分页: 我想通过将UIScrollView放入页面并在每个页面中使用新内容更新来修改此内容:Objective c 具有2个视图的UIScrollView分页,objective-c,ios,ios5,uiscrollview,Objective C,Ios,Ios5,Uiscrollview,我尝试使用本教程中的两个视图实现分页: 我想通过将UIScrollView放入页面并在每个页面中使用新内容更新来修改此内容: -(void)addContent:(NSString*)txt{ int size = 5; UITextView *txtView; int row = 0; //from left int xPlace = 0; //space between row's int rowSpace = 20;
-(void)addContent:(NSString*)txt{
int size = 5;
UITextView *txtView;

//from left
int xPlace = 0;
//space between row's
int rowSpace = 20;
//from top
int yPlace = 10;
// int button_with = scrollView.frame.size.width;
int button_height = 20;
for (int i = 0; i < size; i++) {
txtView = [[UITextView alloc] initWithFrame:CGRectMake(xPlace, row*rowSpace+yPlace, scrollView.frame.size.width, 2*button_height)];
[txtView setFont:[UIFont fontWithName:@"ArialMT" size:14]];
txtView.backgroundColor = [UIColor blueColor];
[txtView setText:[NSString stringWithFormat:@"Numer %@ - %i",txt,i]];
// answerCheck.titleLabel.font = [UIFont boldSystemFontOfSize:fontSize];
[scrollView addSubview:txtView];
[txtView release];
row++;
}
[scrollView setContentSize:CGSizeMake(scrollView.frame.size.width, txtView.frame.size.height*size)];
}
-(void)addContent:(NSString*)txt{
int size=5;
UITextView*txtView;
int行=0;
//从左
int-xPlace=0;
//行之间的间距
int行空间=20;
//自上而下
int yPlace=10;
//int按钮_with=scrollView.frame.size.width;
int按钮高度=20;
对于(int i=0;i
其想法是,滚动时,只需使用新内容替换uiviewcontroller。它呼吁:
- (void)setPageIndex:(NSInteger)newPageIndex
{
pageIndex = newPageIndex;
if (pageIndex >= 0 && pageIndex < [[DataSource sharedDataSource] numDataPages])
{
NSDictionary *pageData =
[[DataSource sharedDataSource] dataForPage:pageIndex];
label.text = @"Tekstas";//[pageData objectForKey:@"pageName"];
textView.text = [pageData objectForKey:@"pageText"];
[self addContent:[pageData objectForKey:@"pageText"]];
CGRect absoluteRect = [self.view.window
convertRect:textView.bounds
fromView:textView];
if (!self.view.window ||
!CGRectIntersectsRect(
CGRectInset(absoluteRect, TEXT_VIEW_PADDING, TEXT_VIEW_PADDING),
[self.view.window bounds]))
{
textViewNeedsUpdate = YES;
}
}
}
-(void)setPageIndex:(NSInteger)newPageIndex
{
pageIndex=newPageIndex;
如果(pageIndex>=0&&pageIndex<[[DataSource sharedDataSource]numDataPages])
{
NSDictionary*页面数据=
[[DataSource sharedDataSource]dataForPage:pageIndex];
label.text=@“Tekstas”;/[pageData objectForKey:@“pageName”];
textView.text=[pageData objectForKey:@“pageText”];
[自添加内容:[pageData objectForKey:@“pageText”];
CGRect absoluteRect=[self.view.window
convertRect:textView.bounds
fromView:textView];
如果(!self.view.window||
!cGRECT交叉点报告(
CGRectInset(绝对直接、文本视图填充、文本视图填充),
[self.view.window边界])
{
textViewNeedsUpdate=是;
}
}
}
我被困在这里了。我的文本视图正在更新,但UIscrollView的新内容不会在iPad模拟器中更新
是的,我的意思是在iphone上它可以工作,而在iPad上则不行。如果我想实现此功能,我可以改进什么
也许还有其他方法可以从iOS5进行分页
我会把a试图使之发挥作用的消息来源
您只需使用
nib
文件添加一个UIScrollView
,并固定width
和height
。现在将一些页面制作成UIView
,并将它们添加到UIScrollView
,具有相同的大小和相同的origin
。在主ui视图中
:
- (void)viewDidLoad
{
[super viewDidLoad];
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, scrollView.frame.size.height * 2);
}
-(void)viewWillAppear:(BOOL)animated{
CGFloat h = scrollView.frame.size.height;
[pageView1 setFrame:CGRectMake(0, 0, pageView1.frame.size.width, pageView1.frame.size.height)];
[pageView2 setFrame:CGRectMake(0, h, pageView2.frame.size.width, pageView2.frame.size.height)];
}
并且不要忘记在nib
文件的属性中检查分页启用的UIScrollView
我希望对你有用 对不起,我假设你的滚动是水平的!
