本文介绍了一个iOS应用中实现视图切换的方法，通过使用 UIPanGestureRecognizer 检测用户的滑动手势来平移两个 UIView 控件的位置，从而达到显示不同视图的效果。文章详细展示了如何设置和响应滑动手势，以及如何根据手势状态更新视图。

- (void)loadView
{
	UIView *v = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
	self.view = v;
	v.backgroundColor = [UIColor blackColor];
	

	CGRect frame1 = CGRectMake(-masterWidth, 0, masterWidth, self.view.bounds.size.height);
	CGRect frame2 = self.view.bounds;
	mvc.view.frame = frame1;
	dvc.view.frame = frame2;
	
	[v addSubview:mvc.view];
	[v addSubview:dvc.view];
	
	UIPanGestureRecognizer *p = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(pan:)];
	[self.view addGestureRecognizer:p];
}

- (void)pan:(UIPanGestureRecognizer *)p
{
	UIView *v = p.view;
	
	if (p.state == UIGestureRecognizerStateBegan ||
		p.state == UIGestureRecognizerStateChanged) {
		CGPoint delta = [p translationInView:v.superview];

	}
	else if (p.state == UIGestureRecognizerStateEnded) {
