自定义tabBar控制器

标签：tabbar

一、控制器部分

@end

二、模型部分定义的属性和方法

@property(nonatomic,copy) NSString * title;
/** 图片*/
@property(nonatomic,strong) UIImage * image;//注意uimage使用的是strong，uiimage不是视图

/** 选中时图片*/
@property(nonatomic,strong) UIImage * imageSelected;
- (instancetype)initWithTitle:(NSString *) title andImage:(UIImage *) image;

三、自定义的tabBar部分

@implementation JRTabBar
-(instancetype)initWithFrame:(CGRect)frame andItems:(NSArray *) array{

    self = [super initWithFrame:frame];
    if (self) {
        self.itemArray=array;
        [self addItems];
        
        //默认灰色
        self.backgroundColor=[UIColor lightGrayColor];
        
    }
    return self;

}

#pragma mark - 增加item

- (void)addItems{

    CGFloat space =(kWidth-2*kEdgeMargin-self.itemArray.count*40)/(self.itemArray.count-1);
    for (int i=0;i<self.itemArray.count;i++) {

       JRItem *item= [[[NSBundle mainBundle] loadNibNamed:@"jritem" owner:nil options:nil] firstObject];
        item.tag=100+i;
        
        //1 初始化item
        
        JRItemModel * model=self.itemArray[i];
        item.imageView.image=model.image;
        item.label.text=model.title;
        
        //2 修改坐标
        CGRect frame=item.frame;
        frame.origin.x=kEdgeMargin+i*(space+40);
        item.frame=frame;
        
        //3加入tabbar
        [self addSubview:item];
   
        
        //增加点击手势
        UITapGestureRecognizer * tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(showInfo:)];
        [item addGestureRecognizer:tap];
         
    }
  
}

- (void) showInfo:(UITapGestureRecognizer *) ges{
    NSInteger tag= ges.view.tag;
    [self.delegate changeVC:tag];

}
