iOS development-Imitation VW reviews ipad side navigation bar

Yesterday has actually written a sidebar article, but the feeling is not very clear, this article is added, the ipad read the public comments on the sidebar, basically 90% similar, specific effects can be consulted:

compared to yesterday mainly made two changes, one is the picture and text display position, and the other is about the bottom of the positioning and setting position in the screen when the problem is displayed, the side bar area is self-control, you need to pay attention to the screen when the setting Autoresizingmask, the bottom icon is also set when positioning.

Each button on the navigation bar extracts a parent class Gpdockitem, the code in the header file:

  gpdockitem.h//  grouponproject//Blog Park flyelephant:http://www.cnblogs.com/xiaofeixiang//  Created by Keso on 15/3/11.//  Copyright (c) 2015 Keso. All rights reserved.//#import <UIKit/UIKit.h> @interface gpdockitem:uibutton-(void) imagesetting: (NSString *) BackgroundImage selectedimage: (NSString *) selectedimage; @property (nonatomic,strong)  nsstring  *title;// Background image @property (nonatomic,strong)  nsstring  *backgroundimage;//Select Picture @property (Nonatomic,strong)  NSString  *selectedimage; @end

Compared to the previous code, the main is to add a set background picture and set the selected picture of a hybrid method, defined a Title property, then you can set the text and picture location, rewrite two methods:

Set Picture area-(CGRect) Imagerectforcontentrect: (cgrect) contentrect{    cgfloat  width=contentrect.size.width;    CGFloat  height= contentRect.size.height * 0.7;    Return CGRectMake (0, ten, width, height);} Set Text area-(CGRect) Titlerectforcontentrect: (cgrect) contentrect{    cgfloat  width=contentrect.size.width;    CGFloat  height= contentRect.size.height * 0.3;    CGFloat  position=contentrect.size.height*0.7;    Return CGRectMake (0, position, width, height);}

Set the background picture and the selected picture:

-(void) imagesetting: (NSString *) backgroundimage selectedimage: (NSString *) selectedimage{    Self.backgroundimage=backgroundimage;    Self.selectedimage=selectedimage;}

Set the position of the display text and the picture within the area:

-(void) Settitle: (NSString *) title{    [self settitle:title forstate:uicontrolstatenormal];    Self.titlelabel.textalignment=nstextalignmentcenter;    Self.titleLabel.font = [Uifont systemfontofsize:15];    Normal state is gray    [self settitlecolor:[uicolor graycolor] forstate:uicontrolstatenormal];    Switch text color when not clickable    [self settitlecolor:[uicolor orangecolor] forstate:uicontrolstatedisabled];    Set picture properties    Self.imageView.contentMode = Uiviewcontentmodecenter;}

Code in GPDOCKITEM.M:

Inherit from the Gpbottomitem of Gpdockitem, only need to set the auto-scaling property of the portrait and landscape:

  gpbottomitem.m//  grouponproject//flyelephant--http://www.cnblogs.com/xiaofeixiang//  Created by Keso on 15/3/13.//  Copyright (c) 2015 Keso. All rights reserved.//#import ' GPBottomItem.h ' @implementation gpbottomitem/*//only override drawrect:if you perform Cus Tom drawing.//An empty implementation adversely affects performance during animation.-(void) DrawRect: (cgrect) rect {
   
    //Drawing code}*/-(instancetype) initWithFrame: (cgrect) frame{self=[super initwithframe:frame    ];    if (self) {        //auto-scaling        self.autoresizingmask=uiviewautoresizingflexibletopmargin;    }    return self;} @end
   

Positioning in the GPDock.h:

-(void) addlocation{    gpbottomitem *tabitem=[[gpbottomitem alloc]init];        [TabItem imagesetting:@ "Toolbar_switchcity.png" selectedimage:@ "Toolbar_switchcity_selected.png"];        CGFloat y = self.frame.size.height-gpdockitemheight*2-20;    Set position    tabitem.frame = CGRectMake (0, y, 0, 0);        [TabItem settitle:@ "Beijing"];        Set the selected touch Check event    [TabItem addtarget:self Action: @selector (tabitemtouchevent:) forControlEvents: Uicontroleventtouchdown];    Tabitem.tag =4;    [Self addsubview:tabitem];}

Settings in the GPDock.h:

-(void) addsetting{    gpbottomitem *tabitem=[[gpbottomitem alloc]init];        [TabItem imagesetting:@ "Toolbar_setting.png" selectedimage:@ "Toolbar_setting_selected.png"];          CGFloat y = self.frame.size.height-gpdockitemheight-10;    Set position    tabitem.frame = CGRectMake (0, y, 0, 0);        [TabItem settitle:@ "Settings"];    Set the selected touch Check event    [TabItem addtarget:self Action: @selector (tabitemtouchevent:) forControlEvents: Uicontroleventtouchdown];    Tabitem.tag =5;    [Self addsubview:tabitem];}

The two have the same, separate merge is the line, specific to the future to implement the business logic, add it to the Gpdock:

-(Instancetype) initWithFrame: (cgrect) frame{    self=[super initwithframe:frame];    if (self) {        //Auto Scaling height scalable, right margin can be scaled        self.autoresizingmask=uiviewautoresizingflexibleheight| Uiviewautoresizingflexiblerightmargin;       Set background picture        Self.backgroundcolor=[uicolor colorwithpatternimage:[uiimage imagenamed:@ "Toolbar_bg_tabbar.png"];                Add tab        [Self addtabitems];                Add Settings        [self addlocation];                Add Settings        [self addsetting];    }    return self;}

The final results are as follows:

Time hurriedly, line pen hasty, unavoidably omission, welcome correct, write Bo not easy, if have favor, please heartily recommend, recently need to change work, have relevant iOS post can provide under, first thanked ~
