I have a custom UITextField added to the UINavigationItem.titleView. But it is not becomeFirstResponder. Why so?
- (void) viewDidLoad
{
[super viewDidLoad];
UITextField *titleTextField = [[UITextField alloc] initWithFrame:CGRectMake(65.0f, 8.0f, 160.0f, 30.0f)];
titleTextField.text = #"Untitled";
titleTextField.textAlignment = UITextAlignmentCenter;
titleTextField.textColor = [UIColor whiteColor];
titleTextField.font = [UIFont boldSystemFontOfSize:20.0f];
//titleTextField.backgroundColor = [UIColor redColor];
titleTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
titleTextField.delegate = self;
titleTextField.tag = 2;
self.navigationItem.titleView = titleTextField;
[titleTextField becomeFirstResponder]
}
Please advice.
Thanks in Advance,
Bharathi.
Try [self.navigationItem.titleView becomeFirstResponder]; instead of [titleTextField becomeFirstResponder];
You also need to conform the UITextFieldDelegate protocol. I think you do not have conform the protocol.
in .h file (for example)
#interface RootViewController : UITableViewController<UITextFieldDelegate>
#end
Try this:
[titleTextField becomeFirstResponder];
then:
self.navigationItem.titleView = titleTextField;
tell me if any luck...

How do I make UINavigationBar title to be user editable, I've tried setting the titleView to be a textfield however it doesn't look the same.. It's missing that outline or drop shadow. I'm aiming for it to look like the default one.
This is what i'm implementing at the moment:
_titleField = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 200, 26)];
[_titleField setDelegate:self];
_titleField.text = _bugDoc.data.title;
_titleField.font = [UIFont boldSystemFontOfSize:20];
_titleField.textColor = [UIColor whiteColor];
_titleField.textAlignment = NSTextAlignmentCenter;
self.navigationItem.titleView = _titleField;
- (void)viewDidLoad
{
[super viewDidLoad];
[self loadTitle];
}
- (void)loadTitle
{
txtField_navTitle = [[UITextField alloc] initWithFrame:CGRectMake(self.view.bounds.origin.x,7,self.view.bounds.size.width,31)];
txtField_navTitle.delegate = self;
[txtField_navTitle setBackgroundColor:[UIColor clearColor]];
txtField_navTitle.textColor = [UIColor whiteColor];
txtField_navTitle.textAlignment = UITextAlignmentCenter;
txtField_navTitle.borderStyle = UITextBorderStyleNone;
txtField_navTitle.font = [UIFont boldSystemFontOfSize:20];
txtField_navTitle.autocorrectionType = UITextAutocorrectionTypeNo;
txtField_navTitle.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
[self.navigationItem setTitleView:txtField_navTitle];
txtField_navTitle.layer.masksToBounds = NO;
txtField_navTitle.layer.shadowColor = [UIColor whiteColor].CGColor;
txtField_navTitle.layer.shadowOpacity = 0;
[txtField_navTitle release];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
self.title = textField.text;
return YES;
}
Please dont forget to #import <QuartzCore/QuartzCore.h>
Try this way this works for me.
// Custom Navigation Title.
UILabel* tlabel=[[UILabel alloc] initWithFrame:CGRectMake(0,0, 300, 40)];
tlabel.text=self.title;
tlabel.textAlignment=NSTextAlignmentCenter;
tlabel.font = [UIFont boldSystemFontOfSize:17.0];
tlabel.textColor=[UIColor colorWithRed:7.0/255.0 green:26.0/255.0 blue:66.0/255.0 alpha:1.0];
tlabel.backgroundColor =[UIColor clearColor];
tlabel.adjustsFontSizeToFitWidth=YES;
self.navigationItem.titleView=tlabel;
I am trying to add border around UITextView by using
self.textView.layer.borderWidth = 1;
self.textView.layer.borderColor = [[UIColor brownColor] CGColor];
but it is not showing up. If anyone can help me with why it is not showing up. Eventhough i have added Quartz framework. But still is not showing up.
#import "uitextviewViewController.h"
#import <QuartzCore/QuartzCore.h>
#implementation uitextviewViewController
#synthesize textView;
#synthesize navBar;
- (void)dealloc {
[navBar release];
[textView release];
[super dealloc];
}
- (void) viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem * button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:#selector(done:)];
[[self navigationItem] setRightBarButtonItem:button];
[button release];
self.textView = [[[UITextView alloc] initWithFrame:self.view.frame] autorelease];
self.textView.textColor = [UIColor whiteColor];
self.textView.font = [UIFont fontWithName:#"Arial" size:15];
self.textView.delegate = self;
self.textView.backgroundColor = [UIColor brownColor];
self.textView.layer.borderWidth = 1;
self.textView.layer.borderColor = [[UIColor brownColor] CGColor];
self.textView.textAlignment = UITextAlignmentCenter;
self.textView.text = #"This is UITextView\n\nThis is UITextView\n\nThis is UITextView\n\nThis is UITextView\n\nThis is UITextView.";
self.textView.scrollEnabled = YES;
[self.view addSubview: self.textView];
}
I will appreciate help.
Thanks in advance.
Following code is use for the give the arc of the UITextbox or other controller for that you need to use the #import frame work then you can use the following code for the border or arc shape on the control.
imgThumb.layer.cornerRadius = 5;
imgThumb.layer.masksToBounds = YES;
imgThumb.layer.borderColor = [UIColor grayColor].CGColor;
imgThumb.layer.borderWidth = 0.9;
If any query regarding this please comment here...
Happy coding
Here, use this.
Modify it as you'd like.
UITextFieldWrapper.h
#import <UIKit/UIKit.h>
#interface UITextFieldWrapper : UIView
#property (nonatomic, weak, readonly) UITextField * textField;
#end
UITextFieldWrapper.m
#import "UITextFieldWrapper.h"
#import <QuartzCore/QuartzCore.h>
#implementation UITextFieldWrapper
#synthesize textField = _textField;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.autoresizingMask = UIViewAutoresizingFlexibleWidth;
self.layer.borderWidth = 1.0;
self.layer.borderColor = [[UIColor blackColor] CGColor];
self.backgroundColor = [UIColor whiteColor];
self.clipsToBounds = YES;
UITextField * textField = [[UITextField alloc] initWithFrame:CGRectMake(3, 3, frame.size.width - 6, 21)];
textField.backgroundColor = [UIColor whiteColor];
[self addSubview:textField];
_textField = textField;
}
return self;
}
#end
I added a text field in viewDidLoad but it did not show up on screen.
Here's .h
#import <UIKit/UIKit.h>
#interface SecondViewController : UIViewController{
UITextField *tfText;
}
#property (nonatomic, retain) UITextField *tfText;
#end
Here's .m
- (void)viewDidLoad{
[super viewDidLoad];
[self.view setBackgroundColor:[UIColor lightGrayColor]];
tfText.frame = CGRectMake(65, 100, 200, 50);
tfText.backgroundColor = [UIColor whiteColor];
[tfText setTextColor:[UIColor blackColor]];
tfText.placeholder = #"Test";
[tfText setBorderStyle:UITextBorderStyleNone];
[self.view addSubview:tfText];
}
seems that you need to initialize the object... I mean
UITextField *newTextField = [[UITextField alloc] init];
self.tfText = newTextField;
//....
//all your code here
//....
[newTextField release];
And dont forget to release your instance on dealloc method.
D33pN16h7 is correct, you need to instantiate your object. However I would do it a little differently than described above, there is no reason to create a UITextField instance, and then set your instance to it.
self.tfText = [[UITextField alloc] init];
UITextField entered2 = [[UITextField alloc] initWithFrame:CGRectMake(120.0, 125.0, 150.0, 25.0)];
[entered2 setBackgroundColor:[UIColor whiteColor]];
entered2.text=#"Active";
[self.view addSubview:entered2];
[entered2 release];
My problem is that none of the delegate methods of UITextView get called.
My code, I've not included the whole class, just the relevant parts.
I'm not using an XIB, its all added programatically.
None of my delegate methods get called.
.h
#interface ChatAppViewController : UIViewController <UITableViewDelegate,
UITableViewDataSource, UITextViewDelegate>
{
UITextView * messageTextField;
}
.m
- (void)viewDidLoad
{
messageTextField = [[UITextField alloc] initWithFrame:CGRectMake(5, 408, 310, 70)];
messageTextField.textColor = [UIColor blackColor]; //text color
messageTextField.font = [UIFont systemFontOfSize:17.0]; //font size
[messageTextField setPlaceholder:#"Post a message" ];
messageTextField.backgroundColor = [UIColor whiteColor]; //background color
messageTextField.autocorrectionType = UITextAutocorrectionTypeNo;
messageTextField.keyboardType = UIKeyboardTypeDefault; // type of the keyboard
messageTextField.returnKeyType = UIReturnKeyDone; // type of the return key
messageTextField.delegate = self;
messageTextField.hidden = NO;
[self.view addSubview:messageTextField];
}
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView {
NSLog(#"textViewShouldBeginEditing");
return YES;
}
- (void)textViewDidBeginEditing:(UITextView *)textView {
NSLog(#"textViewDidBeginEditing");
}
- (void)textViewDidChange:(UITextView *)textView {
NSLog(#"textViewDidChange");
}
- (void)textViewDidChangeSelection:(UITextView *)textView {
NSLog(#"textViewDidChangeSelection");
}
- (BOOL)textViewShouldEndEditing:(UITextView *)textView {
NSLog(#"textViewShouldEndEditing");
return YES;
}
- (void)textViewDidEndEditing:(UITextView *)textView {
NSLog(#"textViewDidEndEditing");
}
Many Thanks,

This line:
messageTextField = [[UITextField alloc] initWithFrame:...
Creates a UITextField, not a UITextView.
Simple. You created a UITextField object. That is why none of the delegate methods were not called - because they were the wrong ones. Replace your viewDidLoad with the following:
- (void)viewDidLoad
{
messageTextField = [[UITextView alloc] initWithFrame:CGRectMake(5, 408, 310, 70)];
messageTextField.textColor = [UIColor blackColor]; //text color
messageTextField.font = [UIFont systemFontOfSize:17.0]; //font size
messageTextField.backgroundColor = [UIColor whiteColor]; //background color
messageTextField.autocorrectionType = UITextAutocorrectionTypeNo;
messageTextField.keyboardType = UIKeyboardTypeDefault; // type of the keyboard
messageTextField.returnKeyType = UIReturnKeyDone; // type of the return key
messageTextField.delegate = self;
messageTextField.hidden = NO;
[self.view addSubview:messageTextField];
}
Compile it and now delegate functions should fire just fine.
If you create UITextField in .xib, then declare in .h as IBOutlet... And connect textfield's delegate to File's Owner, otherwise everything should be perfect.
In my project i'm using a UITextField which is embedded into a plain white UIButton with rounded corners in order to create a "beautiful" text field. This code is used several times in different views so I decided to create a custom UIView for this purpose. The code for this custom UIView:
BSCustomTextField.h
#import <Foundation/Foundation.h>
#interface BSCustomTextField : UIView {
UIButton* btnTextFieldContainer;
UITextField* textField;
NSString* text;
}
#property (retain, nonatomic) UIButton* btnTextFieldContainer;
#property (retain, nonatomic) UITextField* textField;
#property (retain, nonatomic) NSString* text;
-(id)initWithPosition:(CGPoint)position;
#end
BSCustomTextField.m
#import "BSCustomTextField.h"
#import <QuartzCore/QuartzCore.h>
#implementation BSCustomTextField
#synthesize btnTextFieldContainer, textField, text;
-(id)initWithPosition:(CGPoint)position{
if (self == [super init]) {
btnTextFieldContainer = [[UIButton alloc] initWithFrame:CGRectMake(position.x, position.y, 260, 50)];
btnTextFieldContainer.backgroundColor = [UIColor whiteColor];
[[btnTextFieldContainer layer] setCornerRadius:3.];
[[btnTextFieldContainer layer] setMasksToBounds:YES];
[[btnTextFieldContainer layer] setBorderWidth:0.];
textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 240, 30)];
textField.backgroundColor = [UIColor whiteColor];
textField.clearButtonMode = UITextFieldViewModeAlways;
textField.returnKeyType = UIReturnKeySend;
textField.keyboardType = UIKeyboardTypeEmailAddress;
textField.font = [UIFont fontWithName:#"Helvetica-Bold" size:20.];
[btnTextFieldContainer addSubview:textField];
[self addSubview:btnTextFieldContainer];
}
return self;
}
-(void)dealloc{
[btnTextFieldContainer release];
[textField release];
[super dealloc];
}
#end
So, when using this view in the viewDidLoad of the container view (see code below) the view is properly rendered on the desired position and looks exactly as specified but it does not react on touch events and thus does not become first responder when touched.
Code:
searchTextField = [[BSCustomTextField alloc] initWithPosition:CGPointMake(30, 150)];
searchTextField.textField.placeholder = NSLocalizedString(#"lsUserName", #"");
[[(BSPlainHeaderWithBackButtonView*)self.view contentView] addSubview:searchTextField];
Calling [searchTextField.textField becomeFirstResponder] programmatically works properly and makes the keyboard to appear.
But, the interesting part is, if I embed the code of BSCustomTextField inline in my container just like this:
UIButton* btnTextFieldContainer = [[UIButton alloc] initWithFrame:CGRectMake(30, 150, 260, 50)];
btnTextFieldContainer.backgroundColor = [UIColor whiteColor];
[[btnTextFieldContainer layer] setCornerRadius:3.];
[[btnTextFieldContainer layer] setMasksToBounds:YES];
[[btnTextFieldContainer layer] setBorderWidth:0.];
searchTextField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 240, 30)];
searchTextField.backgroundColor = [UIColor whiteColor];
searchTextField.clearButtonMode = UITextFieldViewModeAlways;
searchTextField.returnKeyType = UIReturnKeySend;
searchTextField.keyboardType = UIKeyboardTypeEmailAddress;
searchTextField.font = [UIFont fontWithName:#"Helvetica-Bold" size:20.];
searchTextField.placeholder = NSLocalizedString(#"lsUserName", #"");
[btnTextFieldContainer addSubview:searchTextField];
[[(BSPlainHeaderWithBackButtonView*)self.view contentView] addSubview:btnTextFieldContainer];
[btnTextFieldContainer release];
everything works as expected and the textfield reacts on touches. The type of the searchTextField is properly set in the header file for each case. The only difference is that in the first case I have an additional wrapping UIView on the UIButton and the UITextFiled. I have no idea what to do to make the text field to become first responder on touch.
Thanks a lot in advance,
Roman
Ok, I've got the solution. raaz's point to the UIResponder class tipped me off to the idea that there must be something wrong in the responder chain, thus I did a little research and found this topic: Allowing interaction with a UIView under another UIView in which exact the same problem is discussed.
Here is the new working code for BSCustomTextField.m
#import "BSCustomTextField.h"
#import <QuartzCore/QuartzCore.h>
#implementation BSCustomTextField
#synthesize btnTextFieldContainer, textField, text;
-(id)initWithPosition:(CGPoint)position{
if (self == [super init]) {
btnTextFieldContainer = [[UIButton alloc] initWithFrame:CGRectMake(position.x, position.y, 260, 50)];
btnTextFieldContainer.backgroundColor = [UIColor whiteColor];
[[btnTextFieldContainer layer] setCornerRadius:3.];
[[btnTextFieldContainer layer] setMasksToBounds:YES];
[[btnTextFieldContainer layer] setBorderWidth:0.];
textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 240, 30)];
textField.backgroundColor = [UIColor whiteColor];
textField.clearButtonMode = UITextFieldViewModeAlways;
textField.returnKeyType = UIReturnKeySend;
textField.keyboardType = UIKeyboardTypeEmailAddress;
textField.font = [UIFont fontWithName:#"Helvetica-Bold" size:20.];
[btnTextFieldContainer addSubview:textField];
[self addSubview:btnTextFieldContainer];
}
return self;
}
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {
// UIView will be "transparent" for touch events if we return NO
return YES;
}
-(void)dealloc{
[btnTextFieldContainer release];
[textField release];
[super dealloc];
}
#end
Since the clickable area fills out the entire BSCustomTextField view we can simply return YES in pointInside:withEvent:
Thank you all for pointing me into the right direction.
Refer UIResponder class
This class has instance method becomeFirstResponder: & isFirstResponder:
Also do not forget to set textfield editing property to YES
Oh, you're completely wrong with doing this way. You should add stretchable image into UIImageView and put it below UITextField.
UIImage *backgroundImage = [[UIImage imageNamed:#"fieldBackground.png"] stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0];
Or you can try to disable userInteraction in UIButton.
