Ios 如何在横向方向上自动打开SWRevealViewController侧面板
我正在尝试使用Ios 如何在横向方向上自动打开SWRevealViewController侧面板,ios,objective-c,swrevealviewcontroller,Ios,Objective C,Swrevealviewcontroller,我正在尝试使用SWRevealViewController使我的应用程序在设备转向横向时自动显示侧面板,并且我可以在应用程序最初打开时显示侧面板,但不能在打开后显示。基本上,我试图让它的行为有点像iPad上的邮件应用程序,只是你仍然可以在横向模式下手动关闭侧面板。我在AppDelegate中尝试了这一点,但没有成功: #import "AppDelegate.h" #import "SWRevealViewController.h" @implementation AppDelegate -
SWRevealViewController
使我的应用程序在设备转向横向时自动显示侧面板,并且我可以在应用程序最初打开时显示侧面板,但不能在打开后显示。基本上,我试图让它的行为有点像iPad上的邮件应用程序,只是你仍然可以在横向模式下手动关闭侧面板。我在AppDelegate中尝试了这一点,但没有成功:
#import "AppDelegate.h"
#import "SWRevealViewController.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
SWRevealViewController *revealViewController = (SWRevealViewController *)self.window.rootViewController;
UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
if (orientation == UIInterfaceOrientationPortrait) {
}
if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) {
if (revealViewController.frontViewPosition == FrontViewPositionLeft) {
[revealViewController revealToggleAnimated:YES];
}
}
return YES;
}
谁能告诉我应该做什么吗?我终于明白了。更简单的方法是将以下代码简单地添加到前视图控制器:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];
[self openSidePanel:interfaceOrientation];
}
- (void)openSidePanel:(UIInterfaceOrientation)orientation
{
if (UIInterfaceOrientationIsLandscape(orientation)) {
[self.revealViewController setFrontViewPosition:FrontViewPositionRight animated:YES];
}
else {
[self.revealViewController setFrontViewPosition:FrontViewPositionLeft animated:YES];
}
}
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
[self openSidePanel:toInterfaceOrientation];
}
现在,当我将iPad旋转到横向模式时,侧面板会自动打开;当我将其旋转回纵向模式时,它会关闭侧面板。我遇到了一个问题,当iphone处于纵向模式时,swrevealcontroller工作查找,并允许用户在打开菜单时滚动。当进入横向模式时,菜单按预期打开,但我无法滚动到菜单中的所有选项!?你遇到过这个问题吗?
