How to display a UIButton in front of all views in UINavigationController? - iphone

Question

I've got a UIButton that I'd like to display in the same position in front of all of the viewControllers of my UINavigationController, much in the same way that a UINavigationBar would - but in this case, I'd like the button to float in the lower-left corner of the screen, like so:
I could try manually adding it to each viewController, but I'd prefer to do it once and forget about it.
Adding the button as a subview to the UIWindow doesn't seem to work - it winds up behind the rootViewController.
Update: I've figured out a way to do it, but because it involves iOS 7, I can't post the solution here until the NDA is lifted. The good news is, it's fairly simple to accomplish this! I'll post something once it's OK to share.

Answer 1

create a NSObject class buttonPanel and allocate the button and you can call the button panel as follow:
buttonPanel * buttonPanel = [[buttonPanel alloc] init];
buttonPanel.delegate = self;
[buttonPanel showButtonWithNavigationController:self.navigationController inView:self.parentViewController.view];
ButtonPanel class:
//ButtonPanel.h
#import <Foundation/Foundation.h>
#class ButtonPanel;
#protocol ButtonPanelDelegate <NSObject>
-(void) ButtonPanel:(ButtonPanel*) buttonPanel ;
#end
#interface ChatMessagePanel : NSObject<UIActionSheetDelegate> {
UINavigationController *navigationController;
id<ButtonPanelDelegate> delegate;
}
#property(nonatomic,retain) UINavigationController *navigationController;
#property (nonatomic,retain) id<ButtonPanelDelegate> delegate;
-(void)showButtonWithNavigationController:(UINavigationController*) navigationController inView:(UIView*) view;
#end
// ButtonPanel.m
#import "ChatMessagePanel.h"
#implementation ButtonPanel
#synthesize userListModal,delegate,navigationController;
-(void)showMessageWithNavigationController:(UINavigationController*) _navigationController inView:(UIView*) view
{
self.navigationController = _navigationController;
baseViewWidth = view.frame.size.width;
baseViewHeight = view.frame.size.height;
incomingRequestActionSheet = [[UIActionSheet alloc] initWithTitle:#"" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];
[incomingRequestActionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
[incomingRequestActionSheet showInView:view];
UIButton *blockUserBttn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
[blockUserBttn setTitle:NSLocalizedString(#"BLOCK_USERS",#"") forState:UIControlStateNormal];
[blockUserBttn setBackgroundColor:[UIColor clearColor]];
[blockUserBttn addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *blockUserBarBttn = [[UIBarButtonItem alloc] initWithCustomView:blockUserBttn];
[optionToolBar setItems:[NSArray arrayWithObjects:blockUserBarBttn, nil]];
[incomingRequestActionSheet addSubview:optionToolBar];
}
-(void)buttonAction:(id) sender
{
}
#end

I don't think this is possible in the ios. You must have to do
individual for all view.

You can simply add the UIButton on the window like
[self.window addSubview:Button];
after self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
