The Reinitialization method, which is loaded from Stroyboard, invokes the

-(Instancetype) Initwithcoder: (Nscoder *) adecoder{

if (self = [Super Initwithcoder:adecoder]) {

Self.backgroundcolor=[uicolor Whitecolor];

self.clipstobounds=no;//do not crop child controls

self.selecteditem=0;//Initializing indexes

Set the text color of Tabbaritem

[[Uitabbaritem appearance] Settitletextattributes:[nsdictionary Dictionarywithobjectsandkeys:rgb_color (74, 74, 7 4), Uitextattributetextcolor, Nil] forstate:uicontrolstatenormal];

//

[[Uitabbaritem appearance] Settitletextattributes: [NSDi Ctionary dictionarywithobjectsandkeys:rgb_color (0, 147, 197), Uitextattributetextcolor, Nil]forState: Uicontrolstateselected];

}

return self;

}

-(Instancetype) initWithFrame: (CGRect) frame{

[Self initview];

}

return self;

}

-(void) initview{

[Self addsubview:_centerbtn];

[Self Insertsubview:_gbview belowsubview:_centerbtn];

}

Handling out-of-area click Invalid issues

-(UIView *) HitTest: (cgpoint) point withevent: (Uievent *) event{

if (Self.hidden) {

return [Super Hittest:point withevent:event];

}else {

Convert coordinates

Cgpoint temppoint = [self.centerbtn convertpoint:point fromview:self];

Determine if the clicked point is within the button area

if (Cgrectcontainspoint (Self.centerBtn.bounds, temppoint)) {

_centerbtn.selected = YES;

Back button

return _centerbtn;

}else {

_centerbtn.selected = NO;

__weak __typeof (&*self) weakself =self;

return [Super Hittest:point withevent:event];

}

}

}

Draw horizontal Lines

-(void) DrawRect: (cgrect) Rect {

The middle button width is the height of the Uitabbar, the width of the other buttons is, (self.width-self.height)/4.0

CGFloat buttonw = (self.width-self.height)/4.0;

Cgcontextref context = Uigraphicsgetcurrentcontext ();

Cgcontextsetstrokecolorwithcolor (context, [Uicolor colorwithred:200/255.0 green:200/255.0 blue:200/255.0 alpha:0.8] . Cgcolor);

Cgcontextsetlinewidth (context, single_line_width + 2.0f);

Cgcontextsetlinewidth (context, 5);

Cgcontextbeginpath (context);

CGFloat linemargin = 0;

1PX line, pixel offset

CGFloat pixeladjustoffset = 0;

if (((int) (1 * [UIScreen Mainscreen].scale) + 1)% 2 = = 0) {

Pixeladjustoffset = Single_line_adjust_offset;

}

CGFloat yPos = Linemargin-pixeladjustoffset;

First paragraph line

Cgcontextmovetopoint (context, 0, YPos);

Cgcontextaddlinetopoint (context, buttonw*2+single_line_width*2, YPos);

Cgcontextstrokepath (context);

Second segment line

Cgcontextmovetopoint (context, buttonw*2+self.frame.size.height-single_line_width*2, YPos);

Cgcontextaddlinetopoint (context, self.bounds.size.width, YPos);

Cgcontextsetstrokecolorwithcolor (context, [Uicolor colorwithred:200/255.0 green:200/255.0 blue:200/255.0 alpha:0.8] . Cgcolor);

Cgcontextstrokepath (context);

}

Lazy Loading of custom buttons

-(UIButton *) centerbtn{

if (!_CENTERBTN) {

_CENTERBTN = [UIButton buttonwithtype:uibuttontypecustom];

Set button size to fit picture

UIImage *normalimage = [UIImage imagenamed:@ "3_gray"];

_centerbtn.frame = CGRectMake (0, 0, normalImage.size.width, normalImage.size.height);

[_centerbtn setimage:normalimage Forstate:uicontrolstatenormal];

UIImage *selectimage = [UIImage imagenamed:@ "3_hover"];

[_centerbtn setimage:selectimage forstate:uicontrolstateselected];

Highlight when removing selection

_centerbtn.adjustsimagewhenhighlighted = NO;

Adjust the position of the button according to the picture (the center of the picture in the middle of the tabbar, this time because the button is a part of the Tabbar, so click Invalid, to be processed)

_centerbtn.frame = CGRectMake (([UIScreen mainscreen].bounds.size.width-normalimage.size.width)/2.0,- normalimage.size.height/2.0 + 8, normalImage.size.width, normalImage.size.height);

_centerbtn.transform = Cgaffinetransformmakescale (Centerbuttonscall, Centerbuttonscall);

}

return _centerbtn;

}

Lazy Loading of custom semicircle view

-(UIView *) gbview{

if (!_gbview) {

CGFloat buttonw = self.centerBtn.width;

Gbarcview *gbview = [[Gbarcview alloc]initwithframe:cgrectmake (0,0,buttonw *gbviewscall,buttonw*gbviewscall)];

Gbview.backgroundcolor=[uicolor Whitecolor];

Gbview.layer.maskstobounds=yes;

gbview.layer.cornerradius=buttonw*gbviewscall*0.5f;

Gbview.center = _centerbtn.center;

Gbview.transform = Cgaffinetransformmakescale (Gbviewscall, Gbviewscall);

_gbview = Gbview;

}

return _gbview;

}

-(void) Sethidden: (BOOL) hidden{

[Super Sethidden:hidden];

When manually setting Uitabbar hide, we want to hide custom buttons and backgrounds

[Self.gbview Sethidden:hidden];

[Self.centerbtn Sethidden:hidden];

}

Core part ******

When you configure hidesbottombarwhenpushed Viewcontroller, hide Uitabbar, the frame is changed, and the Y value of Uitabbar is set to the maximum Y value of the screen, it is not visible. We rewrite this method to determine that when frame y is smaller than the screen height, then the Uitabbar is hidden, and we hide the custom controls. Instead, we'll show our custom controls.

-(void) Setframe: (CGRect) frame{

if (Self.superview &&cgrectgetmaxy (self.superview.bounds)!=cgrectgetmaxy (frame)) {

FRAME.ORIGIN.Y =cgrectgetheight (self.superview.bounds)-cgrectgetheight (frame);

//    }

[Super Setframe:frame];

if (Frame.origin.y>=[uiscreen mainscreen].bounds.size.height) {

[Self.gbview Sethidden:yes];

[Self.centerbtn Sethidden:yes];

}else{

[Self.gbview Sethidden:no];

[Self.centerbtn Sethidden:no];

}

}

Adaptation ipad//rewrite the Traitcollection method so that the Uitabbar remains vertically arranged to prevent horizontal arrangement in Ipad11

-(Uitraitcollection *) traitcollection {

if (UIDevice.currentDevice.userInterfaceIdiom = = Uiuserinterfaceidiompad) {

return [Uitraitcollection traitcollectionwithverticalsizeclass:uiuserinterfacesizeclasscompact];

}

return [Super Traitcollection];

}

@end

Setting the adapter Iphonex in a uitabbarcontroller.m file

Use KVC to assign your own tabbar to the system Tabbar

Add the following code to the Viewdidload method

Copy the custom file to the system using KVC

[Self Setvalue:_mctabbar forkeypath:@ "TabBar"];

Add a view setting Uitabbar height to the [custom] Uitabbar of the system

[Self setuptabbar];

-(void) setuptabbar{

To delete an existing Tabbar

CGRect rect = self.tabBar.frame;

[Self.tabbar Removefromsuperview]; Remove the lower bar from the Tabbarcontroller

[Self.tabBarController.tabBar Removefromsuperview];

Rect.size.height = 49;

RECT.ORIGIN.Y = [UIScreen mainscreen].bounds.size.height-49;

UIView *myview = [[UIView alloc] init];

Myview.frame = rect;

Myview.backgroundcolor = [Uicolor Whitecolor];

[Self.view Addsubview:myview];

}

Customizing files referenced in the Uitabbar

GBArcView.h

#define SINGLE_LINE_WIDTH (1/[UIScreen Mainscreen].scale)

#define SINGLE_LINE_ADJUST_OFFSET ((1/[UIScreen Mainscreen].scale)/2)

@interface Gbarcview:uiview

@end

Gbarch.m

#import <QuartzCore/QuartzCore.h>

#import "MATH.H"

#import <CoreGraphics/CoreGraphics.h>

@implementation Gbarcview

-(void) DrawRect: (cgrect) Rect {

Cgcontextref context = Uigraphicsgetcurrentcontext ();

Uicolor *color1 = [Uicolor colorwithred:200/255.0 green:200/255.0 blue:200/255.0 alpha:0.8];

Cgcontextsetstrokecolorwithcolor (context, Color1. Cgcolor);

Cgcontextsetlinewidth (context, single_line_width + 0.5f);

Cgcontextbeginpath (context);

CGFloat Linemargin =self.frame.size.width*0.5f;

1px line, offset pixel point

CGFloat pixeladjustoffset = 0;

if (((int) (1 * [UIScreen Mainscreen].scale) + 1)% 2 = = 0) {

Pixeladjustoffset = Single_line_adjust_offset;

}

CGFloat yPos = Self.frame.size.width*0.5f-pixeladjustoffset;

CGFloat xPos = self.frame.size.width*0.5f-pixeladjustoffset-4.0f;

Cgcontextaddarc (context, XPos, YPos, Self.frame.size.width*0.5-1.f, m_pi*1.08, m_pi*1.95, 0);

Cgcontextdrawpath (context, kcgpathstroke);

Cgcontextstrokepath (context);
