iOS版 - 无法对齐的UIScrollView UIViews

Question

I have UIViewController with UIScrollView and two labels and a button inside it:

UIView
  -UIScrollView
    -UILabel
    -UILabel
    -UIButton

I need to align my UILabels and UIButton after each other dynamically, as every view can have different size. UILabels are okay, but my UIButton goes into the middle of my second UILabel Here is my code:

self.header.text = event.title;
self.header.numberOfLines = 0;
CGFloat headerHeight = [event.title sizeWithFont:[UIFont fontWithName:@"Arial" size:20] constrainedToSize:CGSizeMake(280, 100000) lineBreakMode:UILineBreakModeWordWrap].height;
self.header.frame = CGRectMake(19, 20, 280, headerHeight);

CGFloat positionY = 40 + [self.header.text sizeWithFont:[UIFont fontWithName:@"Arial" size:20] constrainedToSize:CGSizeMake(280, 100000) lineBreakMode:UILineBreakModeWordWrap].height;

CGFloat descriptionHeight = [event.descr sizeWithFont:[UIFont systemFontOfSize:17] constrainedToSize:CGSizeMake(280, 100000) lineBreakMode:UILineBreakModeWordWrap].height;
self.descr.frame = CGRectMake(19, positionY, 280, descriptionHeight);
self.descr.text = event.descr;
self.descr.numberOfLines = 0; 

positionY =  self.descr.frame.origin.y + self.descr.frame.size.height + 40;

buyButton.frame = CGRectMake(19, positionY, 72, 37);

scrollView.contentInset = UIEdgeInsetsMake(contentInset, 0, 0, 0);
[scrollView setContentSize:CGSizeMake(320, positionY+80)];

UIScrollView has flexible height autoresizing mask set in IB.

Here is how it looks:

Can anyone tell me what am I doing wrong?

UPDATE:

If I remove autoresizing mask for my UIScrollView - everything works okay

Answer 1

如果您的问题通过更改滚动视图上的自动调整大小掩码而得以解决，请确保检查按钮和标签上的自动调整大小掩码以确保它们均一致。

Answer 2

使用Count of UISCROLLVIEW子视图并将X轴作为

  CGRECTMAKE((count-count)*100)+x,y,width,height;
