Select a textView without select text inside? - ios

Question

I have a UITextView inside of UITableViewCell. That UITextView I want be selectable but not text to. When the Menu Controller is appearing and i want to perform copy action, copy all text inside not just a part.
I want something like messenger app :
For the moment i have that :
Thank you in advance!

Answer 1

In fact it's not quite so easy, as on the road show up some strange stuff, but I managed to create a customized one.
The steps are as following:
Create a subclass of UITextView
Override canPerformAction:
withSender: for filtering the default actions of the menu
that pops up.
Configuring textView in order not to be able to edit or
select.
Editing UIMenuController items which provide the actions and buttons on the menu
Add different selectors for each UIMenuItem **** (That is because the sender of the selector is not an UIMenuItem, but a UIMenuController which leads to another matter. Check here for more info. A gist by me for that)

Implementation
Set your textView's class to EBCustomTextView and conform to EBCustomTextViewMenuActionDelegate
Interface
#interface ViewController () <EBCustomTextViewMenuActionDelegate>
viewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.textView.menuActionDelegate = self;
}
Protocol conformance
#pragma mark - Delegation
#pragma mark EBCustomTextViewMenuActionDelegate
- (void)customTextView:(EBCustomTextView *)textView didSelectMenuAction:(EBCustomTextViewMenuAction)action {
switch (action) {
case EBCustomTextViewMenuActionCopy:
NSLog(#"Copy Action");
break;
case EBCustomTextViewMenuActionRead:
NSLog(#"Read Action");
break;
case EBCustomTextViewMenuActionDefine:
NSLog(#"Define Action");
break;
default:
break;
}
}
Output
Enjoy :)

Answer 2

you have to use
[UITextView selectAll:self];
or (with specific range)
UITextView.selectedRange = NSMakeRange(0, 5);
or add txtview.delegate = self;
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView {
dispatch_async(dispatch_get_main_queue(), ^{
[textView selectAll:nil]; //nil or self as per needed
});
return YES;
}

Answer 3

Use UILongPressGestureRecognizer Gesture
#import "ViewController.h"
#interface ViewController ()<UIGestureRecognizerDelegate>
{
UITextView * txtV;
UILongPressGestureRecognizer * longPressGestureRecognizer;
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
txtV=[[UITextView alloc]initWithFrame:CGRectMake(20, 50, 280, 300)];
txtV.text = #"Jai Maharashtra";
txtV.userInteractionEnabled=YES;
txtV.selectable=NO;
txtV.editable=NO;
txtV.font= [UIFont italicSystemFontOfSize:[UIFont systemFontSize]];
[self.view addSubview:txtV];
longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(longPressGesture:)];
longPressGestureRecognizer.delegate=self;
[txtV addGestureRecognizer:longPressGestureRecognizer];
}
- (void)longPressGesture:(UILongPressGestureRecognizer *)gestureRecognizer
{
if (gestureRecognizer.state == UIGestureRecognizerStateBegan)
{
txtV.selectable=YES;
[txtV selectAll:self];
}
}
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
[txtV selectAll:self];
if (action == #selector(cut:))
{
return YES;
}
if (action == #selector(selectAll:))
{
return YES;
}
if (action == #selector(copy:))
{
return YES;
}
if (action == #selector(delete:))
{
return YES;
}
txtV.selectable=NO;
return YES;
}

Answer 4

First i start with create for every UITextView in cell a UILongPressGestureRecognizer to recognize long press.
In cellForRowAtIndexPath i just add that code :
UILongPressGestureRecognizer *recognizer1 = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:#selector(handleLongPressText1:)];
messageRecognizer.delaysTouchesBegan = YES;
UILongPressGestureRecognizer *recognizer2 = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:#selector(handleLongPressText2:)];
translateRecognizer.delaysTouchesBegan = YES;
[cell.backgroundViewText1 addGestureRecognizer:recognizer1];
[cell.backgroundViewText2 addGestureRecognizer:recognizer2];
I use two different selectors because i need to know which text to get from cell.
After the methods :
-(void)handleLongPressText1:(UILongPressGestureRecognizer *)gestureRecognizer
{
if ([gestureRecognizer state] == UIGestureRecognizerStateBegan) {
CGPoint p = [gestureRecognizer locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
if (indexPath == nil){
NSLog(#"couldn't find index path");
} else {
[self becomeFirstResponder];
UIMenuController *menuController = [UIMenuController sharedMenuController];
UIMenuItem *resetMenuItem = [[UIMenuItem alloc] initWithTitle:#"Copy" action:#selector(copyMethod)];
UIMenuItem *menuItem = [[UIMenuItem alloc] initWithTitle:#"Read" action:#selector(readButtonAction)];
[menuController setMenuItems:[NSArray arrayWithObjects:resetMenuItem,menuItem, nil]];
CGRect rect =gestureRecognizer.view.frame;
NSLog(#"%#", NSStringFromCGRect(rect));
[menuController setTargetRect:gestureRecognizer.view.frame inView:[[gestureRecognizer view] superview]];
[menuController setMenuVisible:YES animated:YES];
}
}
}
-(void)handleLongPressText2:(UILongPressGestureRecognizer *)gestureRecognizer
{
if ([gestureRecognizer state] == UIGestureRecognizerStateBegan) {
CGPoint p = [gestureRecognizer locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
if (indexPath == nil){
NSLog(#"couldn't find index path");
} else {
[self becomeFirstResponder];
UIMenuController *menuController = [UIMenuController sharedMenuController];
UIMenuItem *resetMenuItem = [[UIMenuItem alloc] initWithTitle:#"Copy" action:#selector(copyMethod)];
UIMenuItem *menuItem = [[UIMenuItem alloc] initWithTitle:#"Read" action:#selector(readButtonAction)];
[menuController setMenuItems:[NSArray arrayWithObjects:resetMenuItem,menuItem, nil]];
CGRect rect =gestureRecognizer.view.frame;
NSLog(#"%#", NSStringFromCGRect(rect));
[menuController setTargetRect:gestureRecognizer.view.frame inView:[[gestureRecognizer view] superview]];
[menuController setMenuVisible:YES animated:YES];
}
}
}
And for disable all default items in UIMenuController use above code
- (BOOL)canPerformAction:(SEL)iAction withSender:(id)iSender {
SEL copySelector = NSSelectorFromString(#"copyMethod");
SEL readSeletor = NSSelectorFromString(#"readButtonAction");
if (iAction == copySelector) {
return YES;
}else if (iAction ==readSeletor){
return YES;
}else{
return NO;
}
return NO;
}
