我正在使用嵌套的UIScrollView实现自定义UIView。
初始化看起来像:
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(10, 10, 252, 200)];
scrollView.backgroundColor = [UIColor clearColor];
scrollView.contentSize = CGSizeMake(500, 400);
scrollView.userInteractionEnabled = YES;
scrollView.pagingEnabled = NO;
scrollView.scrollEnabled = YES;
scrollView.clipsToBounds = YES;
[scrollView setAutoresizesSubviews:YES];
[scrollView setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
[scrollView setDirectionalLockEnabled:NO];
[scrollView setDelegate:self];
[scrollView setShowsHorizontalScrollIndicator:YES];
[scrollView setShowsVerticalScrollIndicator:YES];
[scrollView setBounces:YES];
[scrollView setAlwaysBounceHorizontal:NO];
[scrollView setAlwaysBounceVertical:NO];
[scrollView setBouncesZoom:YES];
[scrollView setDelaysContentTouches:YES];
[scrollView setCanCancelContentTouches:YES];
[scrollView setMaximumZoomScale:1];
[scrollView setMinimumZoomScale:1];
[scrollView setOpaque:YES];
[self addSubview:scrollView];
}
return self;
}
控制器中的:
CustomView *customView = [[CustomView alloc] initWithFrame:CGRectMake(0, 100, 320, 200)];
[self.view addSubview:cut];
问题:滚动视图仅向上滚动(当我向下拖动手指时),当我尝试向左,向右或向下滚动时没有动作
我做错了什么?
答案 0 :(得分:0)
您设置的许多属性与默认值相同。您可以在此处找到默认值:UIScrollView Class Reference
我的建议是删除已经有默认值的属性。特别是滚动的属性。
[scrollView setShowsHorizontalScrollIndicator:YES];
[scrollView setShowsVerticalScrollIndicator:YES];
[scrollView setBounces:YES];
[scrollView setAlwaysBounceHorizontal:NO];
[scrollView setAlwaysBounceVertical:NO];
[scrollView setBouncesZoom:YES];
[scrollView setDelaysContentTouches:YES];
[scrollView setCanCancelContentTouches:YES];
