Ios UIScrollView上的UIButton作为子视图
在我的应用程序中,我实现了非常复杂的控制,它基于Ios UIScrollView上的UIButton作为子视图,ios,uiscrollview,uibutton,Ios,Uiscrollview,Uibutton,在我的应用程序中,我实现了非常复杂的控制,它基于ARScrollViewEnhancer。我需要它来显示多页的UIScrollView。这是我的UIScrollView代码: dateScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(28, 0, dateLabelMaxSize, 45)]; dateScroll.pagingEnabled = YES; dateScroll.clipsToBounds = NO; dateScro
ARScrollViewEnhancer
。我需要它来显示多页的UIScrollView
。这是我的UIScrollView
代码:
dateScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(28, 0, dateLabelMaxSize, 45)];
dateScroll.pagingEnabled = YES;
dateScroll.clipsToBounds = NO;
dateScroll.showsHorizontalScrollIndicator = NO;
dateScroll.backgroundColor = [UIColor clearColor];
dateScroll.contentSize = CGSizeMake(dateLabelMaxSize*[dayArray count], 45);
我使用dateScroll.clipsToBounds=NO代码>用于显示超出框架的页面。这是ARScrollViewEnhancer的代码:
ARScrollViewEnhancer *backForDate = [[ARScrollViewEnhancer alloc] initWithFrame:CGRectMake(0, 80, self.view.frame.size.width, 45)];
[backForDate addSubview:dateScroll];
backForDate._scrollView = dateScroll;
[self.view addSubview:backForDate];
然后,我为UIScrollView
添加了子视图。这是ui标签
和ui按钮
for (int i=0;i<[dayArray count];i++){
UILabel *dateLabel = [[UILabel alloc] initWithFrame:CGRectMake(3+dateLabelMaxSize*i, 5, dateLabelMaxSize, 40)];
dateLabel.backgroundColor = [UIColor clearColor];
dateLabel.textAlignment = UITextAlignmentLeft;
dateLabel.text = @"some text...";
[dateScroll addSubview:dateLabel];
UIButton *dateButton = [UIButton buttonWithType:UIButtonTypeCustom];
//dateButton.backgroundColor = [UIColor redColor];
dateButton.frame = CGRectMake(3+dateLabelMaxSize*i, 5, dateLabelMaxSize-10, 40);
dateButton.tag = i;
[dateButton addTarget:self action:@selector(dateTapped:) forControlEvents:UIControlEventTouchUpInside];
[dateScroll addSubview:dateButton];
}
那么,按钮不起作用((为什么?
Thnx
UPD.
hitTest方法代码。为:
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
if ([self pointInside:point withEvent:event]) {
return _scrollView;
}
return nil;
}
现在:
如果还复制自定义控件中的hitTest方法,则会导致问题,因为它总是返回滚动视图而不是按钮
您需要返回正确的子视图,而不是始终返回子视图,如下所示:
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
UIView *scrv = self.scrollView;
UIView *superView = [super hitTest:point withEvent:event];
if (superView == self)
{
CGPoint scrollViewpoint = [self.scrollView convertPoint:point fromView:self];
for(UIView *view in self.scrollView.subviews) {
if(CGRectContainsPoint(view.frame, scrollViewpoint)) {
return view;
}
}
return scrv;
}
return superView;
}
您必须设置卷轴的内容大小view@Mutawe我做到了。添加到有问题的代码中。dateScroll.contentSize=CGSizeMake(dateLabelMaxSize*[dayArray count],45)@Eugeneteampnikov您是否实施了hitTest?您能否编辑您的问题以包含hitTest方法?@Eugeneteampnikov您能否详细说明哪些不起作用?尝试在hitTest中设置断点,并查看UIButton是否从hitTest返回。
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
UIView *scrv = _scrollView;
UIView *superView = [super hitTest:point withEvent:event];
if (superView == self)
{
CGPoint scrollViewpoint = [_scrollView convertPoint:point fromView:self];
for(UIView *view in _scrollView.subviews) {
if(CGRectContainsPoint(view.frame, scrollViewpoint)) {
return view;
}
}
return scrv;
}
return superView;
}
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
UIView *scrv = self.scrollView;
UIView *superView = [super hitTest:point withEvent:event];
if (superView == self)
{
CGPoint scrollViewpoint = [self.scrollView convertPoint:point fromView:self];
for(UIView *view in self.scrollView.subviews) {
if(CGRectContainsPoint(view.frame, scrollViewpoint)) {
return view;
}
}
return scrv;
}
return superView;
