I am creating some custom UIBarButtonItems for my bottom toolbar with the following method:
- (void)initialisePageNoProperties
{
pageNoTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 50, 30)];
[pageNoTextField setDelegate:self];
pageNoTextField.text = #"0";
pageNoTextField.textColor = [UIColor blackColor];
pageNoTextField.backgroundColor = [UIColor whiteColor];
pageNoTextField.textAlignment = UITextAlignmentRight;
pageNoTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
pageNoTextField.borderStyle = UITextBorderStyleRoundedRect;
pageNoTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
pageNoTextField.keyboardType = UIKeyboardTypeNumberPad;
pageNoTextField.returnKeyType = UIReturnKeyGo;
[pageNoTextField setClearsOnBeginEditing:YES];
pageNoBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:pageNoTextField];
pageNoBarButtonItem.style = UIBarButtonItemStyleBordered;
noOfPagesTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 50, 30)];
noOfPagesTextField.text = #"0";
noOfPagesTextField.textColor = [UIColor blackColor];
noOfPagesTextField.backgroundColor = [UIColor clearColor];
noOfPagesTextField.textAlignment = UITextAlignmentLeft;
noOfPagesTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
noOfPagesTextField.enabled = NO;
noOfPagesBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:noOfPagesTextField];
}
These buttons then get added to the bottom toolbar with the following method:
- (void)configurePageNoDisplay
{
if(![self.navigationController isToolbarHidden])
{
NSMutableArray *items = [[self.navigationController.toolbar items] mutableCopy];
bool insertIntoArray = ([items count] == 10); // without the page number display the items array will contain 10 items
if (insertIntoArray)
{
[items insertObject:pageNoBarButtonItem atIndex:3];
}
else
{
[items replaceObjectAtIndex:3 withObject:pageNoBarButtonItem];
}
if (insertIntoArray)
{
[items insertObject:noOfPagesBarButtonItem atIndex:4];
}
else
{
[items replaceObjectAtIndex:4 withObject:noOfPagesBarButtonItem];
}
[self.navigationController.toolbar setItems:items];
[self SetPageNoDisplay:[pdfViewCtrl GetCurrentPage]];
}
}
and the values for these buttons get set as follows:
- (void)SetPageNoDisplay:(NSInteger) pageNumber
{
pageNoTextField.text = [NSString stringWithFormat:#"%d", pageNumber];
noOfPagesTextField.text = [NSString stringWithFormat:#"of %d", [[pdfViewCtrl GetDoc] GetPageCount]];
}
The buttons and the fields they contain are declared as follows:
#property (strong, nonatomic) IBOutlet UIBarButtonItem *pageNoBarButtonItem;
#property (strong, nonatomic) IBOutlet UIBarButtonItem *noOfPagesBarButtonItem;
#property (strong, nonatomic) IBOutlet UITextField *pageNoTextField;
#property (strong, nonatomic) IBOutlet UITextField *noOfPagesTextField;
Originally they were not declared as IBOutlets - but I read a suggestion that doing so would help my problem - unfortunately it did not help.
I hide/show the bottom toolbar in response to a double tap from the user:
- (void)handleDoubleTap:(UITapGestureRecognizer *)gestureRecognizer
{
[self.navigationController setNavigationBarHidden:![self.navigationController isNavigationBarHidden] animated:true];
[self.navigationController setToolbarHidden:![self.navigationController isToolbarHidden] animated:true];
[self configurePageNoDisplay];
//[sideBarTab setHidden:![sideBarTab isHidden]];
}
The problem I have is that once the toolbar has been hidden - the buttons do not appear again when it is re-shown. If I rotate the iPad after re-showing the toolbar then the buttons appear again.
I ended up resolving this issue by taking a different approach. I used a standard UIToolbar, rather than the navigation controller toolbar. Using Interface Builder I was able to add a plain UIView to the toolbar and then add the 2 UITextFields inside the UIView. This way I did not have to worry about all the code to add the text fields to the toolbar inside of bar button items - or calling the code to reinstate the text fields on orientation change, hiding and showing of the toolbar etc. It ended up being a much simpler and more robust approach.
Use the setToolbarItems method in your UIViewController to set the toolbar buttons and that should solve it.

I am new in iOS and I am facing problem regarding to get the value from custom table view cell to view controller. I am using rate view for rating and I am checking if value of rate is less then 3 then it show have to enter text in the text view and I want to get value in view controller
My code is like this

How can I get label and textview value in viewcontroller and I want to set rate view value to rate view after reload table.
Hear in the Image i am getting five star and If I click on less then 3 star it should have to write comment.I am taking rate value in the label.How can I get both label and textvalue in view controller.Please tell me to update question if you want more data.Thanks in Advance!
So write this in your CustomTableViewCell.h
#property(nonatomic,assign)NSInteger selectedRating;
everytime when the rating is updated in the Cell, you have to change the value of this variable.
In the viewController it depends on when you want to get the value of this cell. For example in this method:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
CustomTableViewCell *yourCell = (CustomerTableViewCell*)[tableView cellForRowAtIndexPath:indexPath];
NSLog(#"%lu",yourCell.selectedRating);
}
Let me know if this was helpful!
Another way without a variable is to read the NSString in the statusLabel and change the string to a NSInteger variable...
If you are using your delegate...
Then implement the delegate RateViewDelegatein the viewController. The delegate is called in the class to which it is assigned...
Try this
You have to add the #property (nonatomic, weak) NSObject<RateViewDelegate>* delegate;
to the header file of your CustomTableViewCell.h in the method
-(UITableViewCell) cellForRowAtIndexPath....
you have to assign the delegate like this
cell.delegate = self;
Now modify your cell delegate method to this
- (void)rateView:(RateView *)rateView ratingDidChange:(int)rating {
self.statusLabel.text = [NSString stringWithFormat:#"%d", rating];
NSLog(#"Rating value =%#",self.statusLabel.text);
StatusValue=statusLabel.text;
NSLog(#"Status Value String =%#",StatusValue);
// Hear I am getting value of rating..in StatusValue..
int status=[StatusValue intValue];
if(status<=3)
{
commenttxtview.hidden=NO;
}
else{
commenttxtview.hidden=YES;
}
if([self.delegate respondsToSelector:#selector(rateView:ratingDidChange:)]){
[self.delegate rateView:rateView ratingDidChange:rating];
}
}
I am trying to replicate Facebook Messenger App, where there is a UITextView attached to the top of the keyboard.
Due to the nature of this app I need my view to be attached, instead of manually scrolling up and down a ScrollView when the keyboard appears.
This can be achieved by using a inputAccessoryView.
I read the docs on it here.
The documentation is very brief and says:
"This property is typically used to attach an accessory view to the system-supplied keyboard that is presented for UITextField and UITextView objects.
The value of this read-only property is nil. If you want to attach custom controls to a system-supplied input view (such as the system keyboard) or to a custom input view (one you provide in the inputView property), redeclare this property as read-write in a UIResponder subclass.
You can then use this property to manage a custom accessory view. When the receiver becomes the first responder, the responder infrastructure attaches the accessory view to the appropriate input view before displaying it."
I have tried declaring a property
#interface CommentViewController ()
#property (nonatomic, readwrite, retain) UIView *inputAccessoryView;
#end
And then setting it:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 20, 320, 100)];
[view setBackgroundColor:[UIColor greenColor]];
self.inputAccessoryView = view;
}
Then I have tried calling both of these:
[self.tableView becomeFirstResponder];
[view becomeFirstResponder];
Nothing happens. What am I doing wrong?
*Note - Extra information: I am using a UITableViewController that I want to have a UIView attached as an inputAccessoryView. Once I get the view working then I will add in a UITextView and more, but this is mainly an example.
Any help is greatly appreciated!
Add input accessory to your textField or textView rather than to pure UIView.
self.mytextField.inputAccessoryView = view;
The inputAccessoryView is a property of the UIResponder class. It allows you to define a custom input accessory view to display when the receiver becomes the first responder. Usually an instance of UIToolBar should be set as the accessory view.
A toolbar sample:

Now assuming that we have a set of text field fields and text views we could use them to initialize an instance of our toolbar.
MYInputAccessoryToolbar *accessoryToolbar = [MYInputAccessoryToolbar toolbarWithInputItems:#[_passwordCurrentField, _passwordNewField, _passwordVerifyField]];
And then each of these fields will have a custom accessory view like this.
Remove self.inputAccessoryView = view; and then add the code below anywhere after -(void)viewDidLoad { ... } where view is your UIView:
-(void) viewDidLoad {
....
}
- (UIView *)inputAccessoryView
{
return self.view;
}
I am posting this answer to show other people my exact code and how easy it actually was, however all the credit goes to MadNik.
In your view controller class where you want a keyboard, in the implementation add the following:
#implementation CommentViewController {
UIView *toolbar;
UITextView *commentTextView;
UIButton *postComment;
}
The toolbar is the actual view that gets docked to your keyboard, and the rest of the objects go on top of the view.
Next it is as simple as initiating the toolbar and setting its frame:
toolbar = [[UIView alloc]initWithFrame:CGRectMake(0, self.view.frame.size.height-50, self.view.frame.size.width, 50)];
[toolbar setBackgroundColor:[UIColor whiteColor]];
I make the frame of the toolbar initially sit right at the bottom of the view controller.
Next I just initiate the rest of the objects I want on my toolbar, e.g the UITextField and a UIButton. Just lay them out how you want:
commentTextView = [[UITextView alloc]initWithFrame:CGRectMake(8, 8, self.view.frame.size.width - 16 - 75, 34)];
[commentTextView setBackgroundColor:[UIColor colorWithWhite:0.97 alpha:1]];
commentTextView.layer.cornerRadius = 5;
[commentTextView setFont:[UIFont fontWithName:#"Avenir Next" size:20]];
[commentTextView setTextColor:[UIColor colorWithWhite:0.35 alpha:1]];
postComment = [[UIButton alloc]initWithFrame:CGRectMake(self.view.frame.size.width-75, 0, 75, 50)];
[postComment setTitle:#"Post" forState:UIControlStateNormal];
[postComment.titleLabel setFont:[UIFont fontWithName:#"Avenir Next" size:20]];
[postComment setTitleColor:[UIColor colorWithRed:(255/255.0) green:(40/255.0) blue:(80/255.0) alpha:1.0] forState:UIControlStateNormal];
Next add your objects to your tool bar:
[toolbar addSubview:commentTextView];
[toolbar addSubview:postComment];
Now this is where the magic happens: You simply set your UITextView's inputAccessoryView to whatever view you want to be docked to the keyboard.
In this case it is toolbar, because the toolbar is acting as a dock that holds everything else.
Now all you need to do is add your toolbar to your view controller, and when you tap the UITextView, since its inputAccessoryView it the toolbar, the toolbar will be docked to the keyboard!
Since I am using a UITableViewController, I had to add my toolbar to the window:
[[[UIApplication sharedApplication]delegate].window addSubview:toolbar];
So simple! No extra classes or anything needs to be made!
I've created 5 UIView dynamically, which consists of one UILabel and one UIButton each. When I click button, the UIView will setHidden. But it works only on one not other four uiviews.

}
#property(nonatomic,retain)IBOutlet UILabel *welcome;
#property(nonatomic,retain)CustomView *custom;

Kindly help me. I am new in iOS development. I need here to create UIView with differrnt reference and that reference assign to UIButton to close that particular UIView but I could not get result out.
You could use UISegmentedControl along with number of xib for each UIView.
In each UIView you can place the required UIControls and link the same.
In the delegate method of SegmentedControl 'indexDidChangeForSegmentedControl:(UISegmentedControl *)sender' on each index remove the earlier UIView and add the required UIView.
In the main header file add the IBOutlet for each UIView
#property (nonatomic, weak) IBOutlet UIView *view1;
#property (nonatomic, weak) IBOutlet UIView *view2;
In .m file in the delegate method 'indexDidChangeForSegmentedControl'
- (IBAction)indexDidChangeForSegmentedControl:(UISegmentedControl *)sender {
NSUInteger index = sender.selectedSegmentIndex;
if (UISegmentedControlNoSegment != index) {
if (currentIndex == index) {
return;
}
currentIndex = index;
switch (index) {
case 0:
{
[self.previousView removeFromSuperview];
[self.view addSubview:view1];
self.previousView = view1;
}
break;
case 1:
{
[self.previousView removeFromSuperview];
[self.view addSubview:view2];
self.previousView = view2;
}
break;
}
}
}
Hope this helps.
If you want to use properties, you will have to make a property for each view. Instead, if you want to create them dynamicaly you could store the references to each view in an array.
The next you should know/do is to add a tag to each button. A tag is just a number, which in this case should reference to its position in the Array.
Then based on the button tag (that you can retrieve from the sender) you can retrieve the proper view/button from the array and change the Hidden property on it.
For example (pseudo code/this wont compile):
Creating the views array
#property (nonatomic, strong) NSMutableArray *views;
In View did load create the views
views = [[NSMutableArray alloc] init];
int nrOfViews = 5;
for(int a=0; a<=nrOfViews; a++){
UIView *view = create UIView here.
UIButton *button = create button here.
[view addSubView: button];
[button setTag: a];
[views addObject: view];
}
reference to the view through the pointer retained in the array, find the right one based on the button tag.
-(void)buttonPressed:(UIButton *)sender
{
UIView *view = [views objectAtIndex: sender.tag]; //using the button tag to identify the right view.
[view setHidden: yes];
}
Try something like this:
- (void) buttonPressed: (UIButton*) sender
{
UIView* view = sender.superview;
view.hidden = YES;
}
You need to make some changes as follows
#property(nonatomic,strong)IBOutlet UILabel *welcome; // new arc code
#property(nonatomic,strong)UIView *custom; // new arc code
self.custom = [[UIView alloc]initWithFrame:CGRectMake(20, yAxis, 100, 44)];
I have been trying to incorporate a UIView/Toolbar above my keyboard but have had no luck. When I added a toolbar it was scrambled so thus I need to put it into a UIView but the UIView does not want to appear above the keyboard. Code Below:
My Header:
#property (nonatomic, Strong) IBOutlet UITextView *textView;
#property (nonatomic, strong) IBOutlet UIToolbar *TitleBar;
#property (nonatomic, weak) IBOutlet UIView *AddView;
The ViewDidLoad:
- (void)viewDidLoad
{
// observe keyboard hide and show notifications to resize the text view appropriately
/*[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
*/
if ([self respondsToSelector:#selector(setNeedsStatusBarAppearanceUpdate)]) {
// iOS 7
[self performSelector:#selector(setNeedsStatusBarAppearanceUpdate)];
} else {
// iOS 6
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}
self.attributionTitle.delegate = self;
self.attribution.delegate = self;
textView.scrollEnabled = YES;
// quoteText.layer.borderColor = [UIColor blackColor].CGColor;
// quoteText.layer.borderWidth = 1.0f;
// textView.delegate = self; // code or in IB
[textView becomeFirstResponder];
[super viewDidLoad];
// Do any additional setup after loading the view.
}
The textViewDidBeginEditing:
-(void)textViewDidBeginEditing:(UITextView *)textView
{
self.textView.inputAccessoryView = self.AddView;
}
Here is to show the UIView is connected:
I added the textView.inputAccessoryView = AddView;to the ViewDidLoadthen deleted the view from my storyboard and remade it. Lastly I added the UIView to the bottom black bar.
Adding the inputAccessoryView in textViewDidBeginEditing is probably too late. The input accessory view should be set before that, e.g., in the viewDidLoad method.
Try something like:
-(void)viewDidLoad{
[super viewDidLoad];
UIView
myTextField.inputAccessoryView = [self accessoryViewWithPreviousEnabled:NO nextEnabled:YES];
// more stuff as required...
}
And a method for creating a previous/next button (you'll need to provide your own images for the buttons and implements the previousAccessoryViewButtonTapped: and previousAccessoryViewButtonTapped: methods). It takes two BOOL parameters to indicate if the previous and/or next buttons should be enabled.
#pragma mark - Accessory view methods
-(UIView *)accessoryViewWithPreviousEnabled:(BOOL)previousEnabled nextEnabled:(BOOL)nextEnabled{
previousButton = [UIButton buttonWithType:UIButtonTypeCustom];
previousButton.frame = CGRectMake(10, 2, 60, 30);
[previousButton setImage:[UIImage imageNamed:PREVIOUS_BUTTON] forState:UIControlStateNormal];
previousButton.enabled = previousEnabled;
[previousButton addTarget:self action:#selector(previousAccessoryViewButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
nextButton = [UIButton buttonWithType:UIButtonTypeCustom];
nextButton.frame = CGRectMake(80, 2, 60, 30);
[nextButton setImage:[UIImage imageNamed:NEXT_BUTTON] forState:UIControlStateNormal];
nextButton.enabled = nextEnabled;
[nextButton addTarget:self action:#selector(nextAccessoryViewButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
UIView *transparentBlackView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1024, 34)];
transparentBlackView.backgroundColor = [UIColor colorWithRed:0.f green:0.f blue:0.f alpha:0.6f];
UIView *accessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1024, 34)];
[accessoryView addSubview:transparentBlackView];
[accessoryView addSubview:previousButton];
[accessoryView addSubview:nextButton];
return accessoryView;
}
Note this method is hard coded for an iPad in landscape orientation. You need to change it for an iPhone.
The problem is that your self.AddView is already in your interface (because you put it there, in the storyboard). It can't be in two places at once.
I'm adding a UIViewController which has only an UILabel to the main UIView. I create it like this:
WEPopoverLabel *contentViewController = [[WEPopoverLabel alloc] init];
[contentViewController setContents:#"aaa"];
(The hole code .m):
if (!self.popoverController) {
WEPopoverLabel *contentViewController = [[WEPopoverLabel alloc] init];
[contentViewController setContents:#"aaa"];
contentViewController.lContent.text=#"aaarrr";
self.popoverController = [[[popoverClass alloc] initWithContentViewController:contentViewController] autorelease];
self.popoverController.delegate = self;
self.popoverController.popoverContentSize = CGSizeMake(50.0f, 20.0f);
self.popoverController.passthroughViews = [NSArray arrayWithObject:sender];
CGRect rectForPopover = [self.view convertRect:sender.bounds fromView:sender];
[self.popoverController presentPopoverFromRect:rectForPopover inView:self.view permittedArrowDirections:(UIPopoverArrowDirectionUp|UIPopoverArrowDirectionDown) animated:YES];
[contentViewController release];
}
Well, WEPopoverLabel is being created because it shows up in my window and also executes setContents because I've got a NSLog which is printing in my console.
However, the label is not being changed. This is the content of WEPopoverLabel:
#interface WEPopoverLabel : UIViewController{
IBOutlet UILabel * lContent;
}
-(void)setContents:(NSString *) theContent;
and .m
#implementation WEPopoverLabel
-(void)setContents:(NSString *) theContent{
lContent.text = theContent;
NSLog(#"texto fijado");
}
In the .xib, I've connected the lContent to File's owner.
Why is not being updated the text of UILabel?
In the UIViewController, have you connected the main view in the xib to the file owner as well as connecting the label?
Also have you added WEPopoverLabel to the view after it is created:
[currentView addSubview:contentViewControler]
I would give the label a background colour so you can tell if it is actually beng displayed.
-(void)setContents:(NSString *) theContent{
lContent = [[UILabel alloc] init]
lContent.text = theContent;
NSLog(#"texto fijado");
