UIPicker Keyboard conflict

spire_bt · 12-03-2010, 03:21 AM

what i have now is 3 textFields and whenever i touch textField1 or textField2 Picker changes values and there is no keyboard. When i touch textField3 keyboard appears and the picker goes hidden.Now if i dismiss the keyboard by clicking return and then click textField1 picker appears again, but if i dont dismiss the keyboard BY CLICKING BUTTON it stays over the picker. What I need is when the keyboard is firstResponder (and i see it on the screen) to hide it if i click on the textField1 and only to see the picker

Code:

    int variabla;
        
            -(void)textFieldDidBeginEditing:(UITextField *)textField{
            	[pickerView setHidden:YES];
            	if (textField1.editing == YES) {
            		[textField1 resignFirstResponder];
            		[pickerView setHidden:NO];
            		variabla = 1;
            	}else if (textField2.editing == YES) {	
            		[textField2 resignFirstResponder];
            		[pickerView setHidden:NO];
            		variabla = 2;
            	}	
            	NSLog(@"variabla %d",variabla);	
            	[pickerView reloadAllComponents];
            }
            
            - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
            {
            	return 1;
            }
            - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
            {
            	if (variabla == 1) {
            		return [pickerArray1 count];
            	}else if (variabla == 2) {
            		return [pickerArray2 count];
            	}else {
            		return 0;
            	}	
            }
            - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;
            {	
            	if (variabla == 1) {
            		return [pickerArray1 objectAtIndex:row];		
            	}else if (variabla == 2) {
            		return [pickerArray2 objectAtIndex:row];
            	}else {
            		return 0;
            	}	
            }
            - (void)textFieldShouldReturn:(UITextField *)textField{	
            	[textField resignFirstResponder];
            }
    - (void)viewDidLoad {
        [super viewDidLoad];
    	[pickerView setHidden:YES];
    	pickerArray1 = [[NSMutableArray alloc] initWithObjects:@"0", @"1", @"2", nil];
    	pickerArray2 = [[NSMutableArray alloc] initWithObjects:@"3", @"4", @"5", nil];
    }

I hope u havenot tried :-

Code:

   -(void)textFieldDidBeginEditing:(UITextField *)textField{
            	[pickerView setHidden:YES];
            	if (textField1.editing == YES) {
            		[textField1 resignFirstResponder];
                       [textField3 resignFirstResponder];
            		[pickerView setHidden:NO];
            		variabla = 1;
}....

Yea I've tried that and also [textField resignFirstResponder]; like it is in the textFieldShouldReturn function for the return button

well here is the fix

Code:

int variabla;

-(void)textFieldShouldBeginEditing:(UITextField *)textField {
	[pickerView setHidden:YES];
	if ([textField isEqual:textField3]) {
		
	}
	else if([textField isEqual:textField1])
	{
		[textField3 resignFirstResponder];
		[self performSelector:@selector(textFieldFirstResponderOnDelay1) withObject:nil afterDelay:0.3];
	}else {
		[textField3 resignFirstResponder];
		[self performSelector:@selector(textFieldFirstResponderOnDelay2) withObject:nil afterDelay:0.3];
	}
}

-(void)textFieldFirstResponderOnDelay1{ 
	[pickerView setHidden:NO];
	variabla = 1;
	
	NSLog(@"variabla %d",variabla);	
	[pickerView reloadAllComponents];
}
-(void)textFieldFirstResponderOnDelay2{ 
	
	[pickerView setHidden:NO];
	variabla = 2;
	
	NSLog(@"variabla %d",variabla);	
	[pickerView reloadAllComponents];
}
