Closed 8 years ago.
I have one TableViewCell that has UITextField in it.
I want when click out of UITextField hidden keyboard but I don't about that.
this is my code:
#implementation TextFieldCell
#synthesize Textfield,placeholder;
- (void)awakeFromNib
{
// Initialization code
Textfield = [self makeTextField];
[self addSubview:Textfield];
placeholder = [self PlaceHolderLabel];
[self addSubview:placeholder];
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (UITextField *)makeTextField
{
CGRect TextFrame = CGRectMake(0,0,300,80);
UITextField *textfield = [[UITextField alloc]initWithFrame:TextFrame];
textfield.delegate = self;
textfield.textColor = [UIColor colorWithRed:0/256.0 green:84/256.0 blue:129/256.0 alpha:1.0];
textfield.backgroundColor = [UIColor yellowColor];
textfield.placeholder = [NSString stringWithFormat:#"Mamal"];
UIView *spacerleftView = [[UIView alloc] initWithFrame:CGRectMake(0,0,20,20)];
UIView *spacerrightView = [[UIView alloc] initWithFrame:CGRectMake(0,0,20,20)];
[textfield setLeftViewMode:UITextFieldViewModeAlways];
[textfield setRightViewMode:UITextFieldViewModeAlways];
textfield.leftView = spacerleftView;
textfield.rightView = spacerrightView;
return textfield;
}
- (UILabel *)PlaceHolderLabel{
NSString *labelText = Textfield.placeholder;
Textfield.placeholder = nil;
CGRect labelFrame = CGRectMake(0,0,280,80);
UILabel *placeholderLabel = [[UILabel alloc] initWithFrame:labelFrame];
[placeholderLabel setTextColor:[UIColor lightGrayColor]];
[placeholderLabel setText:labelText];
placeholderLabel.textAlignment = NSTextAlignmentRight;
return placeholderLabel;
}
- (UILabel *)clearPlaceHolderLabel{
NSString *labelText = nil;
CGRect labelFrame = CGRectMake(0,0,280,80);
UILabel *placeholderLabel = [[UILabel alloc] initWithFrame:labelFrame];
[placeholderLabel setText:labelText];
return placeholderLabel;
}
-(void)textFieldDidBeginEditing:(UITextField *)textField {
//Keyboard becomes visible
//perform actions.
NSLog(#"start");
}
-(void)textFieldDidEndEditing:(UITextField *)textField{
NSLog(#"end");
}

Answer 1

Add gesture recogniser in viewDidLoad :
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(closeKeyboard:)];
[self.view addGestureRecognizer:tap];
and then implement closeKeyboard:
- (IBAction)closeKeyboard:(id)sender {
[self.view endEditing:YES];}

my friend I had this problem but I can solve that.
you don't need add UITextField in TableViewCell , you can create TextField in ViewController or TableViewController that your tableView is inner it and then add TextField inside any cell that you want.
like this code:
ViewController.h
#interface ViewController : UIViewController <UITableViewDataSource,UITableViewDelegate,UITextFieldDelegate>
#property (nonatomic,strong) UITableView *table;
#property (weak,nonatomic) UITextField *Textfield;
ViewController.m
#implementation ViewController
#synthesize table,Textfield;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
//add table in view
table = [self makeTableView];
[self.view addSubview:table];
[self.view setBackgroundColor: RGB(193,60,46)]; //will give a UIColor objct
//run textfield programmatically
Textfield = [self makeTextField];
//hide keyboard with hideKeyboard selector
UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(hideKeyboard)];
[self.table addGestureRecognizer:gestureRecognizer];
}
- (void) hideKeyboard {
[Textfield resignFirstResponder];
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.view endEditing:YES];
}

Answer 4

Try to use
[self.view setEditing:YES];
in -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

Answer 5

try this:
// somewhere in viewDidLoad
UITapGestureRecognizer * tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapOnBackground)];
[self.view addGestureRecognizer:tapRecognizer];
self.view.userInteractionEnabled = YES;
// ...
- (void)tapOnBackground
{
[self.view endEditing:YES];
}

Answer 6

Add this code in your textField implementation method.
//Set to Remove Keyboard from view
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
After that create dismissKeyboard method.
//First Responder Remove Keyboard
-(void)dismissKeyboard {
[Textfield resignFirstResponder];
}
