OC中UITabbar的适配[iphoneX和Ipad适配]

自定可以UITabar

自定义UITabar头文件

#import

 

@interface MCTabBar : UITabBar

@property (nonatomic, strong) UIButton *centerBtn; //中间按钮

@end

自定义UITabar m文件

#import "GBArcView.h"

//#import ""

#define SCREEN_WIDTH [[UIScreen mainScreen] bounds].size.width

#define GBVIEWSCALL 1.2

#define CENTERBUTTONSCALL 1.1

@property (nonatomic,strong) GBArcView *gbview; //半圆View

@property(assign,nonatomic)int index;//UITabBar子view的索引

@end

 

@implementation MCTabBar

//重新初始化方法,从stroyboard 中加载,会调用

        self.clipsToBounds=NO;//不裁剪子控件

        self.selectedItem=0;//初始化索引

        //设置tabBaritem 的文字颜色

        //        [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:RGB_COLOR(74, 74, 74), UITextAttributeTextColor, nil] forState:UIControlStateNormal];

            }

        return [super hitTest:point withEvent:event];

    }else {

        //转换坐标

        CGPoint tempPoint = [self.centerBtn convertPoint:point fromView:self];

        //判断点击的点是否在按钮区域内

        if (CGRectContainsPoint(self.centerBtn.bounds, tempPoint)){

            _centerBtn.selected = YES;

//    CGContextSetLineWidth(context, 5);

    CGContextBeginPath(context);

    CGFloat lineMargin =0;

    

    //1PX线,像素偏移

    CGFloat pixelAdjustOffset = 0;

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

        pixelAdjustOffset = SINGLE_LINE_ADJUST_OFFSET;

    }

    CGFloat yPos = lineMargin - pixelAdjustOffset;

    

    //第一段线

    CGContextMoveToPoint(context, 0, yPos);

    CGContextAddLineToPoint(context, buttonW*2+SINGLE_LINE_WIDTH*2, yPos);

    CGContextStrokePath(context);

}

 

//自定义按钮的懒加载

-(UIButton *)centerBtn{

    if(!_centerBtn){

       _centerBtn = [UIButton buttonWithType:UIButtonTypeCustom];

        //  设定button大小为适应图片

        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];

        //去除选择时高亮

        _centerBtn.adjustsImageWhenHighlighted = NO;

////自定义半圆View的懒加载

    if(!_gbview){

 }

 

-(void)setHidden:(BOOL)hidden{    

    [super setHidden:hidden];

    //手动设置UITabBar 隐藏时,我们要将自定义的按钮和背景隐藏

    [self.gbview setHidden:hidden];

    [self.centerBtn setHidden:hidden];

}

//******核心部分******

//当配置  hidesBottomBarWhenPushed 的viewController ,隐藏UITabBar时,会改变其frame,就是将UITabBar 的Y值设为屏幕最大的y值,就不可见。我们重写这个方法,判断当frame的y小于屏幕的高度 ,那么UITabBar就是被隐藏了,这时候我们将自定的控件隐藏。相反的,我们就显示我们的自定义控件。

-(void)setFrame:(CGRect)frame{

//    if (self.superview &&CGRectGetMaxY(self.superview.bounds) !=CGRectGetMaxY(frame)) {

//        frame.origin.y =CGRectGetHeight(self.superview.bounds) -CGRectGetHeight(frame);

        [self.gbview setHidden:YES];

        

        [self.centerBtn setHidden:YES];

    }else{

        [self.gbview setHidden:NO];

        [self.centerBtn setHidden:NO];

        

    }

}

//适配ipad

//重写traitCollection方法,使UITabbar保持图为垂直排列,防止在ipad11出现水平排列

- (UITraitCollection *)traitCollection {

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

        return [UITraitCollection traitCollectionWithVerticalSizeClass:UIUserInterfaceSizeClassCompact];

    }

    return [super traitCollection];

}

 @end

在UITabBarController.m文件中设置适配iPhoneX

//利用KVC 将自己的tabbar赋给系统tabBar

ViewDidLoad方法添加如下代码

  //利用kvc将自定义的文件copy给系统

    [self setValue:_mcTabbar forKeyPath:@"tabBar"];

  给系统的[自定义]的UITabBar添加一个View设置UITabBar的高度

   [self setupTabBar];

 

- (void)setupTabBar{

    //删除现有的tabBar

    CGRect rect = self.tabBar.frame;

    [self.tabBar removeFromSuperview];  //移除TabBarController自带的下部的条

//    [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];

}

 

 

 

 

 

 

 

 

自定义UItabBar中引用的文件

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

#import "Math.h"

#import

 

@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线,偏移像素点

    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);

 

}

@end

适配IPhoneX

Swift中让TabBarItem的图标和文件在IPad中仍然是上下排列
