我正在尝试在我的应用程序中使用MMDrawerController。我已经下载了源代码和依赖项。这是我添加到AppDelegate中的代码。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIViewController * leftDrawer = [[UIViewController alloc] init];
UIViewController * center = [[UIViewController alloc] init];
UIViewController * rightDrawer = [[UIViewController alloc] init];
MMDrawerController * drawerController = [[MMDrawerController alloc]
initWithCenterViewController:center
leftDrawerViewController:leftDrawer
rightDrawerViewController:rightDrawer];
UINavigationController * navigationController = [[UINavigationController alloc] initWithRootViewController:center];
[navigationController setRestorationIdentifier:@"MMExampleCenterNavigationControllerRestorationKey"];
[self.drawerController setRestorationIdentifier:@"MMDrawer"];
[self.drawerController setMaximumRightDrawerWidth:200.0];
[self.drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
[self.drawerController setCloseDrawerGestureModeMask:MMCloseDrawerGestureModeAll];
[self.drawerController
setDrawerVisualStateBlock:^(MMDrawerController *drawerController, MMDrawerSide drawerSide, CGFloat percentVisible) {
UIViewController * sideDrawerViewController;
if(drawerSide == MMDrawerSideLeft){
sideDrawerViewController = drawerController.leftDrawerViewController;
}
else if(drawerSide == MMDrawerSideRight){
sideDrawerViewController = drawerController.rightDrawerViewController;
}
[sideDrawerViewController.view setAlpha:percentVisible];
}];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:self.drawerController];
return YES;
}
但是该应用程序运行到黑屏。我缺少什么?
最佳答案
UINavigationController * navigationController =
[[UINavigationController alloc] initWithRootViewController:drawerController];
[self.window setRootViewController:navigationController];
无需在下面的行中写:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
希望这将完美地工作。
