I want to use LGSideMenuController in my project.
I have a trouble from step :
// Initialization
- (instancetype)initWithRootViewController:(UIViewController *)rootViewController;
My Question : Where to add it? I have added it in viewcontroller.h, is it correct?
and second step is:
- (void)setLeftViewEnabledWithWidth:(CGFloat)width
presentationStyle:(LGSideMenuPresentationStyle)presentationStyle
alwaysVisibleOptions:(LGSideMenuAlwaysVisibleOptions)alwaysVisibleOptions;
- (void)setRightViewEnabledWithWidth:(CGFloat)width
presentationStyle:(LGSideMenuPresentationStyle)presentationStyle
alwaysVisibleOptions:(LGSideMenuAlwaysVisibleOptions)alwaysVisibleOptions;
My Question : I have added it in my viewcontroller.h . Is it correct?
and third step is:
ViewController *viewController = [ViewController new];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
LGSideMenuController *sideMenuController = [[LGSideMenuController alloc] initWithRootViewController:navigationController];
[sideMenuController setLeftViewEnabledWithWidth:250.f
presentationStyle:LGSideMenuPresentationStyleScaleFromBig
alwaysVisibleOptions:0];
TableViewController *leftViewController = [TableViewController new];
[sideMenuController.leftView addSubview:leftViewController.tableView];
My Question - I have added it in my viewcontroller.m, but it shows following alert:
not found method setlef... ; setright... and instancetype ;
Please help me to integrate it in my projects.
Actually the people who have created that third party lib have made this abundantly clear.
Answer to your questions; Nopes, You don't have to add any of the methods to your ViewController.h file or anywhere else. Methods are already there in LGSideMenuController.h. Just import it to the place where you intend to use it.
Assuming that you have downloaded the third party lib and added it to your project, this is what you have to do:
First of all add following line to your ViewController.h or AppDelegate.h file (If you are resetting the root VC programmatically). Write it where you have rest of your import statements (That means the top of the file).
#import "LGSideMenuController.h"
Now you can access, create and modify instances of LGSideMenuController in your ViewController.
Then you have to initialize your Side Menu.
The method for that is:
- (instancetype) initWithRootViewController:(UIViewController *)rootViewController;
You can create this like in your didFinishLaunching method in your AppDelegate.m :
ViewController *viewController = [ViewController new]; //Your root VC
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController]; //Create a new navigation controller and assign your VC to that navigation controller
LGSideMenuController *sideMenuController = [[LGSideMenuController alloc] initWithRootViewController:navigationController]; //Create instance of your side menu and pass your navigation controller as parameter here.
Now that you have created an instance, it's time to assign it a left view or right view as you prefer. Right now, let's do left view:
[sideMenuController setLeftViewEnabledWithWidth:250.f presentationStyle:LGSideMenuPresentationStyleScaleFromBig
alwaysVisibleOptions:0];
TableViewController *leftViewController = [TableViewController new];
[sideMenuController.leftView addSubview:leftViewController.tableView];
Now just present your sideMenuController, hook the events to right buttons and that's it. If you don't know how to do that either, look up on other Questions on stackoverflow.
However, IDK your requirements but I'd suggest using SWRevealViewController for side menu. It is simple, elegant and really easy to use with plenty of help.

Right now I'm attempting to integrate this library with an existing app. However, the app already has a rootViewController. Is it possible to simply redirect the frontView this library requires to the current rootViewController that the app has? All I need to implement is the ability to swipe between the rearViewController and the frontViewController like in the first example the library gives.
Yes, but then you need to set the SWRevealController as the new rootViewController.
Here's some sample code to illustrate from application: didFinishLaunchingWithOptions: in your app delegate:
MYAppViewController *mainVC = [[MYAppViewController alloc] init];
// Before using SWRevealViewController I had this line:
// self.window.rootViewController = mainVC
// Used for the rear view of the SWRevealViewController
MYMenuViewController *menuVC = [[MYMenuViewController alloc] init];
SWRevealViewController *revealVC = [[SWRevealViewController alloc] initWithRearViewController:menuVC frontViewController:mainVC];
// Now set the SWRevealViewController as the root view controller
self.window.rootViewController = revealVC;
Just make your rootViewController class inherit from SWRevealViewController, then you wont need to wrap anything.
read the Documentation it explains what to do. You don't need to wrap anything.
I am using a UITableViewController inside of a UINavigationController for my Master and I'm using a UIViewController implementing the GMSMapViewDelegate inside of a UINavigationController for my detail side to display a google map. Currently the table view and the Google map are displaying in the UISplitViewController fine.
I am a beginner who recently finished reading Programming in Objective C and Big Nerd Ranch's guide for IOS 7. I can't figure out how to use the didSelectRowAtIndexPath method to change the camera position with the map. I know how to change the camera position, I've wrote NSLog calls to test whether my app was responding when tapping a particular row, but I can't figure out how to connect the two controllers. I thought about trying to make the controller holding the mapview a delegate for the UITableView, but I am confused as to how to connect the two. What options do I have to carry something like that out.
This is what my appdelegate file looks like.
...
mapviewController *mvc = [[mapViewController alloc]init];
locationTableController *ltc = [[locationTableController alloc]init];
UISplitViewController *svc = [[UISplitViewController alloc]init];
UINavigationController *sideNav = [[UINavigationController alloc]initWithRootViewController:ltc];
UINavigationController *mapNav = [[UINavigationController alloc]initWithRootViewController:mvc];
svc.delegate = mapNav;
svc.viewControllers = #[sideNav,mapNav];
....
I would keep your locationTableController as delegate and datasource for the table. You can use self.splitViewController to access the splitViewController, your mapNav is then at viewControllers[1] and your mapviewcontroller is rootViewController of mapNav. If you implement a changeCameraPosition method in your mapviewcontroller, you can call this from within didSelectRowAtIndexPath. So in didSelectRowAtIndexPath:
UISplitViewController *svc = self.splitViewController;
UINavigationController *mapNav = svc.viewControllers[1];
mapViewController *mvc = (mapViewController *)mapNav.rootViewController;
[mvc changeCameraPosition];
You may need to import the relevant .h files if not already done. Personally I would add some properties to the splitViewController to speed up accessing the other view controllers.
I have an app which displays a simple tableview and I wanted to add the SWRevealViewController as well.
In my appDelegate, before I added the SWReveal VC, I was setting my tableViewController like so...
In didFinishLaunchingWithOptions:
STRTableViewController *tableViewController = [(UINavigationController *)self.window.rootViewController viewControllers][0];
self.delegate = tableViewController;
and then again in the below method:
- (void)loadTableViewData
{
UINavigationController *navVC = (UINavigationController *)self.window.rootViewController;
STRTableViewController *tableVC = navVC.childViewControllers[0];
[tableVC loadTableData]
}
Obviously when I put the SWRevealViewController to the front of the line, this no longer works as it is now trying to call loadTableData from the wrong view controller.
I've tried several ways and keep coming up short. How do I go about accessing the tableViewController now that it is not the first view controller?
If you need more code or logs or anything I'll be happy to post additional info. I have a feeling the answer is right there, I just don't have the experience to see it.
Also, just to be clear, now in the storyboard it goes from Reveal View Controller to Navigation Controller (the tableview's nav VC/ sw_front) and also to the sw_rear VC. Before it simply started with the Navigation Controller.
Thanks!
There's a bunch of ways you can go about keeping a reference to this.
The simplest would be just to keep a reference to the view controller in the AppDelegate.m
So you add a property
#property (nonatomic, strong) STRTableViewController *tableViewController;
Then, whenever and wherever you are instantiating and setting that table view controller, just do something like:
AppDelegate *delegate = [[UIApplication sharedApplication] delegate];
delegate.tableViewController = justCreatedTableViewController;
You'll need to #import "AppDelegate.h" to access the app delegate in other classes where you want to do this.
Then to access it you can just do something like:
- (void)loadTableViewData
{
[self.tableViewController loadTableData]
}
I have created a .xib file containing a UITabBar with 5 UITabBarItems inside. I would like 4 of the 5 tabs to link to the same UIViewController class since they have the exact same interface (only the data differentiate their looks).
Therefore it makes sense for me to instantiate my UIViewController 4 times, once per tab bar item. And then link each one of the UITabBarItems of the .xib with one instance of my UIViewController.
But I cannot figure out a way to take a reference of my xib tab bar items in my UIViewController and send the setTabBarItem message. How could I achieve that ? I was trying somehow to pass the .xib tab bar items on init (overwriting the init) but I didn't manage to reference them. I instantiate the controllers in the AppDelegate after the self.window stuff.
(If I say something weird here, not making sense with the usual iOS programming conventions, please let me know)
Use UITabBarController for this , not sure what you exactly want to do with the same UIViewController but UITabbarController will definitely work;
UITabBarController *tabBarController = [[[UITabBarController alloc] init] autorelease];
ViewController *viewController1 = [[ViewController alloc]initWithNibName:#"ViewController1"];
ViewController2 *viewController2 = [[ViewController2 alloc]initWithNibName:#"ViewController2"];
tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1,viewController1,viewController1,viewController1,viewController2,nil];
self.window.rootViewController = tabBarController;
I've heard Facebook and Google do not use UIStoryboards or nibs because they are difficult to merge – they format all their views programmatically. Are there any resources out there that can provide some guidance as to how best to position assets, handle localization, organize files, etc., when creating all your views without nibs?
The first step would be to create an UINavigationController or a UITabBarController within the AppDelegate's didFinishLaunching method, where you should set the rootViewController for the current UIWindow ([window setRootViewController:]).
Then you just have to create your content viewcontrollers and views. Let's say you want to create a menu, then you should create a MneuViewController which inherits from UIViewController and a MenuView which inherits from UIView. Within the MenuView code you create your view components like labels, textfields or whatever you need. In the MenuViewController you create an instance of the MenuView class and call [self setView:] with that object. Finally you have to add the ViewControllers to your rootViewController.
The AppDelegate should look similar to something like this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
MenuViewController *mvc = [[MenuViewController alloc] init];
UINavigationController *rootViewController = [[UINavigationController alloc] initWithRootViewController: mvc];
[self.window setRootViewController: rootViewController];
[self.window makeKeyAndVisible];
}
Localization has to be done using the macro NSLocalizedString() for which you should find a lot of samples.
Files should be handled using NSFileManager.
For eveything else you should ask more specific questions.
