Objective c 如何获取UIScrollView的索引?
我有一个带有Objective c 如何获取UIScrollView的索引?,objective-c,uitableview,uiscrollview,nsindexpath,Objective C,Uitableview,Uiscrollview,Nsindexpath,我有一个带有UIScrollView的UITableViewCell: cellScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 43)]; cellScroll.contentSize = CGSizeMake(960, 43); cellScroll.contentOffset = CGPointMake(320, 0); cellScroll.decelerationRate = UIScrollViewD
UIScrollView
的UITableViewCell
:
cellScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 43)];
cellScroll.contentSize = CGSizeMake(960, 43);
cellScroll.contentOffset = CGPointMake(320, 0);
cellScroll.decelerationRate = UIScrollViewDecelerationRateFast;
[cell addSubview:cellScroll];
使用ui按钮
可通过以下代码解决此问题:
UIView *animationView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 960, 43)];
[cellScroll addSubview:animationView];
cellButton = [UIButton buttonWithType:UIButtonTypeCustom];
cellButton.frame = CGRectMake(320, 0, 320, 43);
[cellButton addTarget:self action:@selector(didPushCellButton:event:) forControlEvents:UIControlEventTouchUpInside];
[animationView addSubview:cellButton];
- (void)didPushCellButton:(id)sender event:(id)event {
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:theTable];
NSIndexPath *indexPath = [theTable indexPathForRowAtPoint:currentTouchPosition];
}
我也用UIScrollView
尝试了这一点,但没有成功。
此外,我还尝试了一些其他的动作和更多的东西。
但什么都不管用
有人能帮我吗
提前谢谢。您能解释一下什么时候以及为什么需要
indepath
,因为您的按钮代码似乎已经在工作了?这可能有助于某人理解上下文并帮助您解决问题。对于ui按钮
来说,它是有效的,但对于UIScrollView
来说则不然,这就是问题所在。我说:“有了UIButton,这个问题就用这个代码解决了:”
