iOS Development Custom CheckBox control

iOS itself does not have a System checkbox component, but it is often used in actual development, so specifically write a CheckBox control, directly on the code

Effect Chart:

UICheckBoxButton.h files are as follows:

#import

#import "Common.h"

@interface Uicheckboxbutton:uicontrol

{

Uilabel *label;

Uiimageview *icon;

BOOL checked;

ID delegate;

}

@property (retain, nonatomic) ID delegate;

@property (Retain, nonatomic) Uilabel *label;

@property (Retain, nonatomic) Uiimageview *icon;

-(BOOL) ischecked;

-(void) setchecked: (BOOL) flag;

@end

UICHECKBOXBUTTON.M files are as follows:

#import "UICheckBoxButton.h"

@implementation Uicheckboxbutton

@synthesize label,icon,delegate;

-(ID) initWithFrame: (CGRect) Frame {

if (self = [super Initwithframe:frame])

{

Icon =[[uiimageview alloc] Initwithframe:cgrectmake (0, 0, Frame.size.height, frame.size.height)];

[Self setchecked:no];

[Self Addsubview:icon];

Label =[[uilabel Alloc] Initwithframe:cgrectmake (icon.frame.size.width + 7, 0,

FRAME.SIZE.WIDTH-ICON.FRAME.SIZE.WIDTH-10,

Frame.size.height)];

Label.backgroundcolor =[uicolor Clearcolor];

Label.textalignment = Uitextalignmentleft;

[Self Addsubview:label];

[Self addtarget:self Action: @selector (clicked) forcontrolevents:uicontroleventtouchupinside];

}

return self;

}

-(BOOL) ischecked {

return checked;

}

-(void) setchecked: (BOOL) Flag {

if (flag!= checked)

{

Checked = flag;

}

if (checked)

{

[Icon setimage: [UIImage imagenamed:@ "Checkboxselect.png"]];

}

Else

{

[Icon setimage: [UIImage imagenamed:@ "Checkboxnoselect.png"]];

}

}

-(void) clicked {

[Self setchecked:!checked];

if (delegate!= nil)

{

Sel sel = nsselectorfromstring (@ "checkbuttonclicked");

if ([Delegate Respondstoselector:sel])

{

[Delegate Performselector:sel];

}

}

}

-(void) Dealloc {

delegate = nil;

[Label release];

[Icon release];

[Super Dealloc];

}

@end

How to use:

Uicheckboxbutton *checkboxbutton = [[Uicheckboxbutton alloc] Initwithframe:cgrectmake (30, 50, 220, 25)];

Checkboxbutton.delegate = self.delegate;

CheckBoxButton.label.text = [Common gettextbytag:@ "Nocostprompt"];

CheckBoxButton.label.textColor = [Common getcolorbytag:@ "Alertlabelcolor"];

[Self.view Addsubview:checkboxbutton];

[Checkboxbutton release];
