在UIScrollView(Obj-C)中禁用垂直滚动,可以通过以下方法实现:
在UIScrollView的子类中,可以通过重写touchesBegan:withEvent:
、touchesMoved:withEvent:
和touchesEnded:withEvent:
方法来禁用滚动功能。
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesBegan:touches withEvent:event];
[self.nextResponder touchesBegan:touches withEvent:event];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesMoved:touches withEvent:event];
[self.nextResponder touchesMoved:touches withEvent:event];
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesEnded:touches withEvent:event];
[self.nextResponder touchesEnded:touches withEvent:event];
}
可以通过设置UIScrollView的showsVerticalScrollIndicator
属性为NO来禁用垂直滚动条。
self.scrollView.showsVerticalScrollIndicator = NO;
可以通过设置UIScrollView的contentSize
属性来限制滚动范围,从而禁用垂直滚动。
self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width, self.scrollView.frame.size.height);
总结:通过以上方法,可以在UIScrollView(Obj-C)中禁用垂直滚动功能。
