Switching the views in iphone

[santosh_kumar]

Hi all, I created a segmented control with 2 segments(button,textfield).I need to load only the selected segment on to the screen below the segmented control.When i select button first and textfield second, button should not appear on the screen and is same for the textfield. I tried with "hidden" and "removeFromSuperview" but not worked. So please help me.

CODE:
// segmentedControl.m which is a UIViewController
- (void)viewDidLoad
{
[super viewDidLoad];

UISegmentedControl *segmentcontrol=[[ UISegmentedControl alloc ] initWithItems:
[NSArray arrayWithObjects:@"Buttons",@"TextField",@"Picker" ,@"TableView",nil]];

segmentcontrol.frame=CGRectMake(100,10,600,80);
segmentcontrol.selectedSegmentIndex=6;

[segmentcontrol addTarget:self
action:@selector(action
forControlEvents:UIControlEventAllEvents];

[self.view addSubview:segmentcontrol];
}


- (void)actionid)sender
{

NSLog(@"Segment %d selected", [sender selectedSegmentIndex]);

iButtons *button=[[iButtons alloc] initWithFrame:CGRectMake(0,200,400,400)];

iTextField *textfield=[[iTextField alloc]initWithFrame:CGRectMake(0,200,400,400)];


if ([sender selectedSegmentIndex]==0)
{

[button mymethod:NO];
[self.view addSubview:button];

}



if([sender selectedSegmentIndex]==1)
{
[button mymethod:YES];
[textfield mymethod]; // mymethod implements textfield
[self.view addSubview:textfield];

}

}

//iButtons.m file UIView File

-(id)initWithFrameCGRect)frame
{
if ((self = [super initWithFrame:frame ]))
{

NSLog(@"inside init.iButtons");
}
return self;
}


-(void)mymethodBOOL)hide
{

NSLog(@"myMethod");

if(hide==NO)
{

label1=[[UILabel alloc] initWithFrame:CGRectMake(100,100,300,60)];
label1.text=@"RoundedRectangle";
label1.textColor=[UIColor whiteColor];
label1.backgroundColor=[UIColor blackColor];
label1.font=[UIFont systemFontOfSize:30];


[self addSubview:label1];


roundedRectangle=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[roundedRectangle addTarget:self action:@selector(buttonclick) forControlEvents:UIControlEventTouchDown];
roundedRectangle.frame=CGRectMake(480,100,100,90);
[roundedRectangle setTitle:@"Button" forState:UIControlStateNormal];
[self addSubview:roundedRectangle];

}

if(hide==YES)
{


[label1 removeFromSuperview];
[roundedRectangle removeFromSuperview];

}



return self;

}





Thanks in advance.
Santosh.

In the previous posted program, i removed an instance( [label1 removeFromSuperview]...) iButton but not the iButton. So, [iButton removeFromSuperView] is the right solution.


- (void)actionid)sender
{

id existingview1 = [self.view viewWithTag:100];
id existingview2 = [self.view viewWithTag:200];

if(existingview1 != nil)
[existingview1 removeFromSuperview];

else
[existingview2 removeFromSuperview];



if([sender selectedSegmentIndex]==0)
{
buttons = [[iButtons alloc] initWithFrame:CGRectMake(0,200,400,400)];
buttons.tag = 100;
[self.view addSubview:buttons];

[buttons mymethod];
}
else
{

//Text
textFields = [[iTextField alloc] initWithFrame:CGRectMake(0,200,400,400)];
textFields.tag = 200;
[self.view addSubview:textFields];
[textFields mymethod];

}
}
