UIScrollView委托

Question

我有这段代码，它在init中。 这应该是一些滑动单元格，它是由UIScrollView创建的，并且在单元格下面还有一些另一个视图（我自己的动作视图）。

我的问题：如果我想刷我的单元格，UIScrollView不会调用委托方法： - /

有什么建议吗？ THX

self.cellState = kCellStateClosed;
self.cellScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, kSWIPECELL_WIDTH, kSWIPECELL_HEIGHT)];
self.cellScrollView.delegate = self;
self.cellScrollView.showsHorizontalScrollIndicator = NO;
self.cellScrollView.scrollsToTop = NO;
self.cellScrollView.scrollEnabled = YES;

self.tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(selectCell)];
self.longPressGestureRecognizer = [[PAPLongPressGestureRecognizer alloc] initWithTarget:self action:@selector(scrollViewPressed:)];
self.longPressGestureRecognizer.minimumPressDuration = 0.1;

[self.cellScrollView addGestureRecognizer:self.tapGestureRecognizer];
[self.cellScrollView addGestureRecognizer:self.longPressGestureRecognizer];

// Create the content view that will live in our scroll view
self.scrollViewContentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, kSWIPECELL_WIDTH, kSWIPECELL_HEIGHT)];
self.scrollViewContentView.backgroundColor = [UIColor whiteColor];
[self.cellScrollView addSubview:self.scrollViewContentView];

// Add the cell scroll view to the cell
UIView *contentViewParent = [self.subviews firstObject];
NSArray *cellSubviews = [contentViewParent subviews];
[self insertSubview:self.cellScrollView atIndex:0];
for (UIView *subview in cellSubviews)
{
    [self.scrollViewContentView addSubview:subview];
}

self.containingTableView.directionalLockEnabled = YES;

//alloc action view
self.actionView = [[PAPActionCellView alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height) andPages:[self createActionPages] parentCell:self];
[self.cellScrollView insertSubview:self.actionView belowSubview:self.scrollViewContentView];

您缺少的是设置contentSize的{​​{1}}，当您将其设置为比其边界更大的值时，它将开始滚动，即：
