iPhone – Creating a User Interface Kit (UIKIT) – III

The UIKIT FRAMEWORK provides the crucial infrastructure needed to construct and manage iOS apps.

UI SWITCH:-

-(void)  viewDidload

{

UISwitch     * a Switch  =  [[UISwitch alloc]

InitWithFrame :  CGRectMake  (100,100,200,100)];

[ aSwitch  SetOn :   YES];

[ aSwitch  add Target  :  self

action   :   @  Selector  (Switch Changed)

ForControlEvents:   UIControlEventValueChanged];

[ self view  add sub view  :  a switch];

}

-(void)SwitchChanged

{

NSLog  ( @  “ Switch  Changed  called”);

Self .view .backgroundColor = [b8ControlViewController random color];

}

+ (UIColor     *)   random color

{

Static  Bool Seeded  = No;

If (   !seeded)

{

Seeded  =  YES;

Random  (  time  (NULL));

}

CGFloat  red  =   ( CGFloat)  random ()/ ( CGFloat) RAND . MAX;

CGFloat  blue  =  (CGFloat) random  ()/(CGFloat) RAND MAX;

CGFloat green  =   (CGFloat) random()/(CGFloat ) RAND MAX;

NSLog (@  “  color  red  =  %  f green  =     %  f   blue  =   %   f”, Red, green, blue);

return  [ UIColor  colorWithRed :red    green :green blue :blue alpha:1.of];

}

UI SegmentControl:-

-(void) viewDidLoad

{

// segment Control:

NSArray      *a Array    =[NSArray    arraywithObjects: @ “first”,  @  “Second”, nil];

UISegmentedControl  *Segment=

[[ UISegmentedControl alloc]  initWithItems  : aArray];

// Set frame:

Segments1 frame =   CGRectMake  (100,200,200,50.);

// Set Target:

[Segment1  addTarget  :    self

Action  :   @  Selector   ( SegmentChanged)

ForControlEvents:  UIControlEventValueChanged];

// Set  Images  to Segments:

[ segments1 set Image : [UIImage imageNamed : @ “1.jpg”]

For segmentAtIndex :0];

// Set Title for each  Segment:

[ segment1   set Title: @ “one” for SegmentAtIndex:0];

// set tag:

[ Segment1   setTag :1];

// set tint  Color:

[ Segment1    setTintColor   : [UIColor    blackColor]];

// adding  to view:

[self view  addSubView:  Segments1];

[segments1     release];

}

-(IBAction) SegmentControl changed:  (id) Sender

{

UISegmentedControl   *segment   =(UISegmentedControl   *)sender;

If(segment.  SelectedSegmentIndex  = = 0)

{

}

else if ( Segment. SelectedSegmentIndex = = 1)

{

}

}

UISlider  :-

-(void)  viewDidload

{

UISlider     *  aSlider   =   [[ UISlider alloc]

InitWithFrame :  CGRectMake  (50,200,200,50)];

// setting  minimum value:

[ aSlider setMinimumValue:0];

// setting maximum value:

[ aSlider setMaximumValue: 100];

// setting initial value:

[ aSlider setValue  : 50];

// setting  minimum value image:

[ aSlider setMinimumValueImage: [UIImage    imageNamed :@ “1.jpg]];

//setting  maximum value image:

[ aSlider setMaximumvalueImage: [UIImage imageNamed:  @  “2.jpg”]];

// adding target:

[ aSlider  addTarget   :  self

          Action       :  @ selector (SliderChanged:)

     ForControlEvent   :  UIControlEventValueChanged];

[ self view  add sub  view :  aSlider];

[ a slider       release];

UILabel    *lbl  =   [[ UILabel  alloc]  initWithFrame : CGRectMake             (260,200,50,40.)];

                     [lbl  setBackgroundColor  : [ UIColor  clear color]];

                     [ lbl setText : @ “50”];

                     [ self view addSubView  :  lbl];

                     [lbl release];

                     [ Super viewDidLoad];

         }

-(void) SliderChanged : (id) Sender

 {

UISlider     * bSlider   =   (  UISlider     *)   sender;

Lbl. Text  =   [  NSString StringWith Format: @ “%.0.of”, bSlider .value];

}

UIActivityIndicatorView:-

-(void) viewDidLoad

{

UIActivityIndicatorView *activity  =

[[UIActivityIndicatorView alloc] init];

[ activity setActivityviewStyle:

UIActivityIndicatorViewStyleWhite];

// activity center =  self  view center;

Activity. Frame  =   CGRectMake   self. View  . center;

Activity .frame  = CGRectMake (self view center .x, self. View. Center .y, 40,40);

[ activity setHidesWhenStopped :YES];

[ activity  startAnimating];

[ self view addSub view : activity];

[activity release];

}

UIProgress View:-

.h file:-

# import   <UIKIT/UIKIT .h>

@ interface slider view controller: UI view controller

{

Float  value;

UIProgressView        *progress;

}

@ end

. m file:-

-(void) viewDidLoad

{

Progress   = [[ UIProgressView    alloc] initWithFrame:

                          CGRectMake  (100,300,200,40)];

[ self view addSub view: Progress];

[ NSTimer ScheduledTimerWithTimeInterval :0.1

                  Target    :  self

                Selector    :  @ selector ( time Change)                         

               UserInfo     :   nil

                 Repeats    :   yes];

}

-(void) timer changed

{

Value+ = 0.1;

NSLog  ( @  “  timer changed called and value is % f”, value);

Int x= (int) value;

If (x = = 1)

Value = 0;

[ progress set progress : value];

}

UIProgressView :-

. h file:-

# import  <UIKIT/UIKIT . h>

@   interface  SliderViewController : UIViewController

{

Float value;

UIProgress view       * progress;

}

@ end

. m file:-

-(void) viewDidLoad

{

Progress  =  [[ UIProgressview  alloc] initWithFrame:

                         CGRectMake  (100,300,200,40)];

[ self view addSubview : Progress];

NSTimer scheduledTimerWithTimeInterval   : 0.1

               Target  :    self
                 
             Selector  :  @  selector( time Change)

            UserInfo   :  nil

             Repeats   :   yes];

}

-(void) timer changed

{

Value  +   =  0.1;

NSLog   (@  “ timer changed  called and value is % f”, value);

Int x = (int) value;

If (x = = 1)

Value   = 0;

[ progress SetProgress :   Value];

}
