Customized tabbar solution 2

Custom tabbar can solve the problem that custom images cannot be displayed (only one color is displayed). Custom tabbar must inherit the uitabbarcontroller

Original Image:

(1), 650) This. width = 650; "src =" http://img.blog.csdn.net/20141010214007546 "/> (2), 650) This. width = 650; "src =" http://img.blog.csdn.net/20141010214352826 "/> (3), 650) This. width = 650; "src =" http://img.blog.csdn.net/20141010214255562 "/> (4), 650) This. width = 650; "src =" http://img.blog.csdn.net/20141010214533649 "/> (5) 650) This. width = 650; "src =" http://img.blog.csdn.net/20141010214329484 "/>

The following is a custom tabbar. Each button can display an image (this prevents the image from displaying only one color)

:

650) This. width = 650; "src =" http://img.blog.csdn.net/20141010213726757 "/>

Code implementation:

First, create a class customtabbar that inherits uibutton,

In the. h file:

// Specify the Protocol to display the corresponding page by clicking the button, just like the system tabbar

@ Protocol customtabbardelegate <nsobject>

-(Void) didselectbaritematindex :( nsinteger) index;

@ End

@ Interface customtabbar: uibutton
@ Property (nonatomic, assign) nsinteger index;
@ Property (nonatomic, retain) ID <mtmtabbardelegate> delegate;
-(ID) initwithframe :( cgrect) frame withimage :( uiimage *) image andselectedimage :( uiimage *) image;
@ End

In the. M file

# Import "customtabbar. H"

@ Interface customtabbar ()

@ End
@ Implementation customtabbar

-(ID) initwithframe :( cgrect) Frame
{
Self = [Super initwithframe: frame];
If (Self ){
// Initialization code

}
Return self;
}

-(ID) initwithframe :( cgrect) frame withimage :( uiimage *) image andselectedimage :( uiimage *) selectedimage {
Self = [Super initwithframe: frame];
If (Self ){
Self. Frame = frame;
[Self setadjustsimagewhenhighlighted: No];
[Self setimage: Image forstate: uicontrolstatenormal];
[Self setimage: selectedimage forstate: uicontrolstateselected];
[Self addtarget: Self action: @ selector (Click :) forcontrolevents: uicontroleventtouchupinside];
}
Return self;
}

-(Void) Click :( uibutton *) BTN {
If ([self. Delegate respondstoselector: @ selector (didselectbaritematindex :)]) {
[Self. Delegate didselectbaritematindex: Self. Index];
}
Switch (INT) (BTN. Selected )){
Case 0:
BTN. Selected = yes;
Break;
Case 1:
BTN. Selected = no;
Break;
Default:
Break;
}
}


@ End

2. Create a class customizedtabbarcontroller to inherit uitabbarcontroller

In the. M file

-(Void) loadviewcontroller
{
Covercollectionviewcontroller * covervc = [[covercollectionviewcontroller alloc] init];
// Covervc. Title = @ "Daily cover ";
Customizednavigationcontroller * covernavc = [[customizednavigationcontroller alloc] initwithrootviewcontroller: covervc];
Covernavc. navigationitem. Title = @ "idailywatch ";

Newstableviewcontroller * newsvc = [[newstableviewcontroller alloc] init];
// Newsvc. Title = @ "watch Magazine ";
Customizednavigationcontroller * newsnavc = [[customizednavigationcontroller alloc] initwithrootviewcontroller: newsvc];

Brandstableviewcontroller * brandsvc = [[brandstableviewcontroller alloc] init];
// Brandsvc. Title = @ "brand wiki ";
Customizednavigationcontroller * brandsnavc = [[customizednavigationcontroller alloc] initwithrootviewcontroller: brandsvc];

Videoscollectionviewcontroller * videosvc = [[videoscollectionviewcontroller alloc] init];
// Videosvc. Title = @ "video ";
Customizednavigationcontroller * videosnavc = [[customizednavigationcontroller alloc] initwithrootviewcontroller: videosvc];

Moreviewcontroller * morevc = [[moreviewcontroller alloc] init];
// Morevc. Title = @ "more ";
Customizednavigationcontroller * morenavc = [[customizednavigationcontroller alloc] initwithrootviewcontroller: morevc];

Self. viewcontrollers = @ [covernavc, newsnavc, brandsnavc, videosnavc, morenavc];
Self. selectedindex = 0;
Release_safe (covernavc );
Release_safe (covervc );
Release_safe (brandsnavc );
Release_safe (brandsvc );
Release_safe (videosnavc );
Release_safe (videosvc );
Release_safe (morenavc );
Release_safe (morevc );
}

-(Void) setuptabbar
{
For (INT I = 0; I <5; I ++ ){
If (I <3 ){
Customtabbar * bar = [[customtabbar alloc] initwithframe: cgrectmake (0 + 80 * I, 0, 80, 49) withimage: [uiimage imagenamed: [nsstring stringwithformat: @ "% d", I + 100] andselectedimage: [uiimage imagenamed: [nsstring stringwithformat: @ "% d", I + 130];
Bar. Index = I;
Bar. Delegate = self;
Bar. backgroundcolor = RGB (245,245,245 );
[Self. tabbar addsubview: bar];
[Bar release];
If (I = 0 ){
Bar. Selected = yes;
}
} Else {
Customtabbar * bar = [[customtabbar alloc] initwithframe: cgrectmake (0 + 40 * (I + 3), 0, 40, 49) withimage: [uiimage imagenamed: [nsstring stringwithformat: @ "% d", I + 100] andselectedimage: [uiimage imagenamed: [nsstring stringwithformat: @ "% d", I + 130];
Bar. Index = I;
Bar. Delegate = self;
Bar. backgroundcolor = RGB (245,245,245 );
[Self. tabbar addsubview: bar];
[Bar release];
}
}
}

-(Void) didselectbaritematindex :( nsinteger) index {
[Self resignbatstate];
Self. selectedviewcontroller = self. viewcontrollers [Index];
}
-(Void) resignbatstate {
Nsarray * arr = [self. tabbar subviews];
For (customtabbar * bar in ARR ){
If ([Bar iskindofclass: [mtmtabbar class]) {
Bar. Selected = no;
}
}
}

-(Void) changeviewcontroller :( uibutton *) button
{
Self. selectedindex = button. Tag;
}

-(Void) didreceivememorywarning
{
[Super didreceivememorywarning];
// Dispose of any resources that can be recreated.
}
