Subclassed UITextView
Here is h file
#interface CTextView : UITextView {
}
#end
Here is m file code
#import "CTextView.h"
#implementation CTextView
- (BOOL)canBecameFirstResponder {
return NO;
}
#end
Here is first UIViewController file in which subclassed UITextview is using
#import "First.h"
#import "CTextView.h"
textView = [[[CTextView alloc] initWithFrame:CGRectMake(0, 0, 320, 410)]autorelease];
[self.view addSubview:textView];
But still not able to prevent copy select all from UITextView. Please let me know if i am still missing anything or doing wrong.
Thanks for help.
Use this to disable copy:
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
return NO;
}
Got it. Now it is working
Here is the code for reference for anyone need it
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
[UIMenuController sharedMenuController].menuVisible = NO; //do not display the menu
if (action == #selector(copy:))
{
return NO;
}
else if (action == #selector(selectAll:))
{
return NO;
}
[self resignFirstResponder]; //do not allow the user to selected anything
return NO;
return [super canPerformAction:action withSender:sender];
}
Now only problem having is Zooming. Now i have to work on that to disable it from UITextView.
Have you set the user interaction enabled to YES?

I have a tableview for showing a list of devices in my application. When viewWillAppear is called, I add the self.searchDisplayController.searchBar as a subview to a headerView. I then assign self.tableView.tableHeaderView = headerView. It looks like this:
I scroll the tableview down so that headerview goes out of view and then go to some other view controller by tapping on a cell. When I come back to this tableView, scroll up to the headerView, the searchBar becomes invisible, however on tapping the invisible area the searchDisplayController gets activated and the cancel button doesn't work. This happens for iOS 7 only. Why is this happening?
Note: It happens only if the headerView is out of the view when I come back to the tableViewController.
I've just had the same issue. When I go to debug into the delegate method of UISearchDisplayController at the end search state, the searchBar becomes a subview of an UIView, not the UITableView. Please see below code:
- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
//My Solution: remove the searchBar away from current super view,
//then add it as subview again to the tableView
UISearchBar *searchBar = controller.searchBar;
UIView *superView = searchBar.superview;
if (![superView isKindOfClass:[UITableView class]]) {
NSLog(#"Error here");
[searchBar removeFromSuperview];
[self.tableView addSubview:searchBar];
}
NSLog(#"%#", NSStringFromClass([superView class]));
}
My solution is remove the searchBar away from current super view, then add it as subview again to the tableView. I've already tested successfully.
Hope that help!

I have the exact same problem. the search bar is still there and can receive touch events. it is however not rendered. I believe the problem is in UISearchDisplaycontroller because it renders fine if I don't use UISearchDisplayController. I ended up writing a custom SearchDisplaycontroller to replace it. it is very basic and only does what I need.
use it is the same way as you would the normal UISearchDisplayController but self.searchDisplayController will not return anything. you will have to use another pointer to refer to the custom search display controller.
looks like a big ugly work around, but the only one that worked for me. keen to hear of alternatives.

Update: on how to use this progammatically
declare an ivar
SearchDisplayController *mySearchDisplayController;
initialize it programmatically
mySearchDisplayController = [[SearchDisplayController alloc]initWithSearchBar:mySearchBar contentsController:self];
adding the searchbar to your tableview
self.tableView.headerView = mySearchBar;
use mySearchDisplayController as reference to the custon class instead on self.searchDisplayController.
In my case, the table view that held the search display controller's search bar in its header view was being reloaded almost as soon as the view appeared. It was at this point that the search bar would cease to render. When I scrolled the table, it would reappear. It's also worth mentioning that my table contained a UIRefreshControl and was not a UITableViewController subclass.
My fix involved setting the search display controller active and then inactive very quickly just before after loading the table (and ending the refresh control refreshing):
[self.tableView reloadData];
[self.refreshControl endRefreshing];
[self.searchDisplayController setActive:YES animated:NO];
[self.searchDisplayController setActive:NO];
A bit of a hack but it works for me.
Using the debugger, I've found that the UISearchBar is initially a child view of the tableHeaderView - but when it disappears, it has become a child of the tableView itself. This has probably been done by UISearchDisplayController somehow... So I did the following hack to simply return the UISearchBar to the header view:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if(!self.searchDisplayController.isActive && self.searchBar.superview != self.tableView.tableHeaderView) {
[self.tableView.tableHeaderView addSubview:self.searchBar];
}
}
Seems to work fine on iOS 7 as well as 6 :)
(checking that the searchDisplayController isn't active is necessary, otherwise the sarch bar disappears during search)
I endorse Phien Tram's answer. Please upvote it. I don't have enough points myself.
I had a similar problem where a search bar loaded from storyboard would disappear when I repeatedly tapped it, invoking and dismissing search. His solution repairs the problem.
There seems to be a bug where repeated invocation and dismissal of the search display controller doesn't always give the search bar back to the table view.
I will say I'm uncomfortable with the solution's dependence on the existing view hierarchy. Apple seems to reshuffle it with every major release. This code may break with iOS 8.
I think a permanent solution will require a fix by Apple.
I had the same issue and I could fix it calling next line after creating the UISearchDisplayController
[self performSelector:#selector(setSearchDisplayController:) withObject:displayController];
My viewDidLoad function look like this:
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 44)];
searchBar.placeholder = NSLocalizedString(#"Search", #"Search");
UISearchDisplayController *displayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
displayController.delegate = self;
displayController.searchResultsDataSource = self;
displayController.searchResultsDelegate = self;
[self performSelector:#selector(setSearchDisplayController:) withObject:displayController];
self.tableView.contentOffset = CGPointMake(0, 44);
self.tableView.tableHeaderView = searchBar;
Thanks to this answer: https://stackoverflow.com/a/17324921/1070393
Use UISearchBar above UITableView,Then make IBOutlet for and connect them with file's owner to UISearchbar
Example- .h file
#import <UIKit/UIKit.h>
#interface LocationViewController : UIViewController<UISearchBarDelegate>
{
BOOL IsSearchOn;
}
#property (strong, nonatomic) IBOutlet UISearchBar *searchBar;
#property (strong, nonatomic) IBOutlet UITableView *TBVLocation;
.m file
#pragma mark -
#pragma mark UISearchBar Delegate Methods
-(void) searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
[self.searchResult removeAllObjects];
if(searchText.length == 0)
{
IsSearchOn=NO;
// [filteredTableData removeAllObjects];
[self.searchBar resignFirstResponder];
// [self .tblView reloadData];
}
else
{
IsSearchOn=YES;
if(searchText != nil && ![searchText isEqualToString:#""])
{
/* NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"SELF contains[c] %#", searchText];
self.searchResult = [NSMutableArray arrayWithArray: [searchArray filteredArrayUsingPredicate:resultPredicate]];*/
for(int i=0;i<[[arrCountryList valueForKey:#"country_name"] count];i++)
{
NSRange titleRange = [[[[arrCountryList valueForKey:#"country_name"] objectAtIndex:i] lowercaseString] rangeOfString:[searchText lowercaseString]];
if(titleRange.location != NSNotFound)
[self.searchResult addObject:[arrCountryList objectAtIndex:i]];
}
[TBVLocation reloadData];
}
}
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
[searchBar resignFirstResponder];
}
-(void)searchBarCancelButtonClicked:(UISearchBar *) searchBar
{
[searchBar resignFirstResponder];
IsSearchOn=NO;
searchBar.text = nil;
[TBVLocation reloadData];
}
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar
{
[searchBar resignFirstResponder];
return YES;
}
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
searchBar.showsCancelButton = YES;
searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
// IsSearchOn=YES;
}
- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
IsSearchOn=NO;
searchBar.showsCancelButton = NO;
[TBVLocation reloadData];
[searchBar resignFirstResponder];
}
It will work like charm.
I've faced similar problem and after some digging, I've found that this is a bug in UISearchBar hierarchy. This hacky solution worked for me in iOS 7, but be aware that this may break in future iOS versions:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
UIView *buggyView = [self.searchDisplayController.searchBar.subviews firstObject];
// buggyView bounds and center are incorrect after returning from controller, so adjust them.
buggyView.bounds = self.searchDisplayController.searchBar.bounds;
buggyView.center = CGPointMake(CGRectGetWidth(buggyView.bounds)/2, CGRectGetHeight(buggyView.bounds)/2);
}
I had the same problem and tested some of the solutions proposed here in this thread, but they didn't solve the problem for me.
Previously, I added and configured the UISearchBar in the
- (void)viewDidLoad
method of my ViewController in code.
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:searchBarView.frame];
searchBar.delegate = self;
searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
ect...
What solved this issue for me was that I added a UISearchbar in the InterfaceBuilder, created an outlet in my ViewController and added this UISearchBar to my UISearchDisplayController.
self.searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar(<--outlet) contentsController:self];
hope this might also help some people
How do we disable Cut-Copy-Paste or Select-SelectAll menu when tapped on a UITextField. I tried with below code but it did not work.
if ([UIMenuController sharedMenuController]) {
[UIMenuController sharedMenuController].menuVisible = NO;
}
Make a subclass if UITextView and implement this function
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
if (action == #selector(paste:) || action == #selector(copy:))//and put other actions also
return NO;
return [super canPerformAction:action withSender:sender];
}
canBecomeFirstResponderhere should do the trick. make sure you delegate your UITextField
- (BOOL)canBecomeFirstResponder {
return NO;
}
i want to restrict the copy or Paste option for particular UITextfield in my Application.
Add the following piece of code in the implementation file of the view controller which containing the UITextField
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
UIMenuController *menuController = [UIMenuController sharedMenuController];
if (menuController) {
[UIMenuController sharedMenuController].menuVisible = NO;
}
return NO;
}
OR
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == #selector(paste:) // or #selector(copy:)
return NO;
return [super canPerformAction:action withSender:sender];
}
Create a subclass of UITextField.
In that subclass, implement
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
if (sel_isEqual(action, #selector(copy:))) //#selector(paste:) {
return NO;
}
return [super canPerformAction:action withSender:sender];
}
Then use this subclass for the field that you don't want to be able to copy in, and use a regular UITextField for the one that you can copy from.
Refer this URL for more info:-
iPhone – Disable the Cut/Copy/Paste Menu on UITextField
UIResponder

You can implement it like this:
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == #selector(paste:)) {
return NO;
}
return [super canPerformAction:action withSender:sender];
}
Otherwise you can write:
- (BOOL)canBecomeFirstResponder {
return NO;
}
To make your UITextField non-editable.
I'm trying to create a custom UIMenuController and display it in my view. Here's my code:
UIMenuController *menuController = [UIMenuController sharedMenuController];
UIMenuItem *listMenuItem = [[UIMenuItem alloc] initWithTitle:#"List" action:#selector(addList:)];
[menuController setMenuItems:[NSArray arrayWithObject:listMenuItem]];
[menuController setTargetRect:CGRectMake(50.0, 50.0, 0, 0) inView:self.view];
[menuController setMenuVisible:YES animated:YES];
[listMenuItem release];
There are no errors or exceptions, but the menu controller just doesn't show up.
You need to do three things:
You need to call -becomeFirstResponder on the view or view controller.
Your view or view controller needs to implement -canBecomeFirstResponder (returning YES).
Optionally, your view or view controller can implement -canPerformAction:action withSender:sender to show/hide menu items on an individual basis.
The answer mentions three things, but to be picky, there are six:
The menu handler must be a UIView. If it isn't, -becomeFirstResponder fails.
The menu handler must have userInteractionEnabled = YES
The menu handler must be in the view hierarchy and its -window property must be the same as the window for the view in the inView: argument.
You need to implement -canBecomeFirstResponder and return YES.
You need to call [handler becomeFirstResponder], before [menu setTargetRect:inView:] is called, or the latter will fail.
You need to call [menu setTargetRect:inView] (at least once) and [menu setMenuVisible:animated:].
In particular points 1-3 above got me. I wanted a custom menu handler class that was a UIResponder at first, which caused -becomeFirstResponder to return NO; then it was a UIView, which failed, then I tried making it a UIButton which worked, but only because userInteractionEnabled defaults to YES for buttons and NO for UIViews.
UIMenuController is visible on any view only if the view is first responder and
- (BOOL)canPerformAction method returns YES
Hence if your menu controller is to be shown on button click, the first line in the button action should be [self becomeFirstResponder]. NOTE: here self is the view which will present the menus.
If your menus are to be shown on long press gesture, then add longPressGesture to the UIView and in the longpress event before writing
[menuController setTargetRect:CGRectMake(50.0, 50.0, 0, 0) inView:self.view];
[menuController setMenuVisible:YES animated:YES];
write [self becomeFirstResponder];
Then follow the steps mentioned by OZ.

In View class if u write return YES alone in canPerformAction you will see all the default menuitems like camera symbol,cut,copy etc..
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
return YES;
}
if u want to show something like camera alone then
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if(action==#selector(_insertImage:))
return YES;
else
return NO;
}
if u want to know about all the actions then

Just in case anyone is having this issue specifically (and randomly) with iOS6: you might want to look at this SO related to having Speak Selection enabled on the device (Settings -> General -> Accessibility -> Speak Selection: On). A small number of my users were not able to see the custom UIMenuItems and this was the cause.
In Swift 3.0 -
In my case I wanted to have the VC pre-select the text in a TextView and display a custom menu for the user to take action on that selection. As mentioned by Kalle, order is very important, especially making setMenuVisible last.
In VC, viewDidLoad:
menuCont = UIMenuController.shared
let menuItem1: UIMenuItem = UIMenuItem(title: "Text", action: #selector(rtfView.textItem(_:)))
let menuItems: NSArray = [menuItem1]
menuCont.menuItems = menuItems as? [UIMenuItem]
In VC, when the user hits a button:
#IBAction func pressed(_ sender: Any) {
self.textView.selectedRange = NSMakeRange(rangeStart, rangeLength)
self.textView.becomeFirstResponder()
menuCont.setTargetRect(CGRect.zero, in: self.textView)
menuCont.setMenuVisible(true, animated: true)
}
Finally, in the sub-class of the TextView:
class rtfView: UITextView {
override var canBecomeFirstResponder: Bool {
return true
}
override func canPerformAction(_ action: Selector, withSender sender: Any!) -> Bool {
if (action == #selector(textItem(_:))) {
return true
} else {
return false
}
}
}
maybe because CGRectMake(50.0, 50.0, 0, 0) creates a CGRect with width = 0 and height = 0?

I want to disable text selection on a UITextView. Until now what i've
already done is:
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
[UIMenuController sharedMenuController].menuVisible = NO;
if (action == #selector(paste:))
return NO;
if (action == #selector(select:))
return NO;
if (action == #selector(selectAll:))
return NO;
return NO;
}
In this away I set UIMenuController to hidden and i put a stop to text copy but the text selection is still visible.
Google results (also StackOverflow) take me to no solution. Has someone already faced the
same problem? Any ideas?
If you want to prevent the text selection but keep links interactions, add the following textview delegate methods
- (void)textViewDidChangeSelection:(UITextView *)textView
{
[textView setSelectedRange:NSMakeRange(NSNotFound, 0)];
}
If you want to disable cut/copy/paste on all UITextView of your application you can use a category with :
#implementation UITextView (DisableCopyPaste)
- (BOOL)canBecomeFirstResponder
{
return NO;
}
#end
It saves a subclassing... :-)
Otherwise, just subclass UITextViewand put :
- (BOOL)canBecomeFirstResponder
{
return NO;
}
textView.editable = NO;
or
[textView setEnabled:NO];
im not sure what u meant
