How to copy self.title? - ios

Question

I'm setting my page title as:
self.title = #"My Title";
Now I want to enable this title as that user can copy this title.
So How do I do that ?
EDIT:
self is my UIViewController class and my view is in navigation controller.
When user hold the title it can show tooltip like "Copy" and title text copied.

Answer 1

You can subclass UILabel named 'YourTitleLabel' and assign it as titleView of UIViewController's navigationItem.
self.navigationItem.titleView = YourTitleLabel;
And you should override several methods of UIResponder.
#interface YourTitleLabel : UILabel
#end
#implementation YourTitleLabel
- (BOOL)canBecomeFirstResponder
{
return YES;
}
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == #selector(copy:)) {
return YES;
}
return NO;
}
- (void)copy:(id)sender
{
[[UIPasteboard generalPasteboard] setString:self.text];
[self resignFirstResponder];
}
#end
Hope helpful for you!

Here is the way :
Make UILable subclass, and add this methods to the class.
TitleLabel.h file:
#import <UIKit/UIKit.h>
#interface TitleLabel : UILabel
#end
and TitleLabel.m file:
#import "TitleLabel.h"
#implementation TitleLabel
- (void)initCommon
{
UILongPressGestureRecognizer *lpRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(handleLongPress:)];
[self addGestureRecognizer:lpRecognizer];
}
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self)
{
[self initCommon];
}
return self;
}
- (id)initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];
if (self)
{
[self initCommon];
}
return self;
}
- (BOOL)canBecomeFirstResponder
{
return YES;
}
- (void)copy:(id)sender
{
[[UIPasteboard generalPasteboard] setString:self.text];
[self resignFirstResponder];
}
- (void)handleLongPress:(UILongPressGestureRecognizer *)sender
{
UIMenuController *menu = [UIMenuController sharedMenuController];
if (![menu isMenuVisible])
{
[self becomeFirstResponder];
[menu setTargetRect:self.frame inView:self.superview];
[menu setMenuVisible:YES animated:YES];
}
}
#end
Now add this lable to your navigation titleView like :
TitleLabel *title = [[TitleLabel alloc] initWithFrame:CGRectMake(0, 0, 150, 50)];
title.textAlignment = NSTextAlignmentCenter;
title.text = #"My title";
title.userInteractionEnabled = YES;
self.navigationItem.titleView = title;
and here is you can copy self.title on long press on lable.

Answer 3

you can set your custom label in self.navigationbar.titleview and set title in your custom label. If that will also not work. then you can try with uitextfield (actually it is weird to set textfield in titleview) with non-editable.

Answer 4

you need to create one sampleLabel class, which is the sub class of UILabel as follows , where you required copy text option use this SampleLabel intead of UILabel
#implementation SampleLabel UILabel
- (void) awakeFromNib
{
[super awakeFromNib];
[self attachTapHandler];
}
- (void) attachTapHandler
{
if (self.tag != 100 ) {
[self setUserInteractionEnabled:YES];
UITapGestureRecognizer *touchy = [[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(handleTap:)];
touchy.numberOfTapsRequired = 2;
[self addGestureRecognizer:touchy];
}
}
- (void) copy: (id) sender
{
[[UIPasteboard generalPasteboard] setString:self.text];
}
- (BOOL) canPerformAction: (SEL) action withSender: (id) sender
{
return (action == #selector(copy:));
}
- (void) handleTap: (UIGestureRecognizer*) recognizer
{
[self becomeFirstResponder];
UIMenuController *menu = [UIMenuController sharedMenuController];
[menu setTargetRect:self.frame inView:self.superview];
[menu setMenuVisible:YES animated:YES];
}
- (BOOL) canBecomeFirstResponder
{
return YES;
}
#end

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
pasteboard.string = self.title;
