我要在我的应用程序中创建从左侧打开它的显示菜单（当我从左向右拖动时，首页从左向右移动）现在我尝试更改它，但我做不到。请指导我如何更改此菜单并将其放在右侧并打开此侧（从右向左拖动时）。
我的朋友这是我的一段代码：
#pragma mark UITouch Logic
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
if (_slideNavigationControllerState == kSlideNavigationControllerStateDrilledDown ||
_slideNavigationControllerState == kSlideNavigationControllerStateSearching)
return;
UITouch *touch = [touches anyObject];
_startingDragPoint = [touch locationInView:self.view];
if ((CGRectContainsPoint(_slideNavigationController.view.frame, _startingDragPoint))
&& _slideNavigationControllerState == kSlideNavigationControllerStatePeeking) {
_slideNavigationControllerState = kSlideNavigationControllerStateDragging;
_startingDragTransformTx = _slideNavigationController.view.transform.tx;
}
// we only trigger a swipe if either navigationBarOnly is deactivated
// or we swiped in the navigationBar
if (!kSVCSwipeNavigationBarOnly || _startingDragPoint.y <= 44.0f) {
_slideNavigationControllerState = kSlideNavigationControllerStateDragging;
_startingDragTransformTx = _slideNavigationController.view.transform.tx;
}
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
if (_slideNavigationControllerState != kSlideNavigationControllerStateDragging)
return;
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:self.view];
[UIView animateWithDuration:0.05f
delay:0.0f
options:UIViewAnimationOptionCurveLinear |
UIViewAnimationOptionBeginFromCurrentState
animations:^{
_slideNavigationController.view.transform = CGAffineTransformMakeTranslation(
MAX(_startingDragTransformTx + (location.x - _startingDragPoint.x),
0.0f),0.0f);
NSLog(@"%d",_slideNavigationController.view.transform);
} completion:^(BOOL finished) {
}];
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
if (_slideNavigationControllerState == kSlideNavigationControllerStateDragging) {
UITouch *touch = [touches anyObject];
CGPoint endPoint = [touch locationInView:self.view];
// Check in which direction we were dragging
if (endPoint.x < _startingDragPoint.x) {
if (_slideNavigationController.view.transform.tx <= kSVCRightAnchorX) {
[self slideInSlideNavigationControllerView];
} else {
[self slideOutSlideNavigationControllerView];
}
} else {
if (_slideNavigationController.view.transform.tx >= kSVCLeftAnchorX) {
[self slideOutSlideNavigationControllerView];
} else {
[self slideInSlideNavigationControllerView];
}
}
}
}
