1.设置scrollview没有反弹效果
scrollview.bounces = NO;
2.在scrollview上添加很多控制器的view，在滑动到最左侧（第一个）view时，再右滑不在是反弹效果，而是调用某个方法时：
步骤1:重写scrollview类，在scrollview类里有个
-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
方法
例如
-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
UIPanGestureRecognizer *pan = (UIPanGestureRecognizer *)gestureRecognizer;
CGPoint point = [pan translationInView:self];
if (point.x>0) {
//向右拖动
self.isRightSlide = YES;
}else
{
//不是向右拖动
self.isRightSlide = NO;
}
}
return YES;
}
步骤2:在添加scrollview的主控制器里实现scrollview的代理方法
#pragma mark -scrollView代理方法
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView;
{
//判断左侧第一个view和scrollview是向右滑动
if (scrollView.contentOffset.x == 0 && myscrollView.isRightSlide == YES) {
//调用第一个视图右滑时要调用的方法
[self someFunction];
}
}
