UITabBar实现自定义背景及UITabBarItem自定义图片和字体

UITabBarItem *firstItem = [[UITabBarItem alloc]initWithTitle:@"测试" image:nil tag:];

 //设置字体颜色(后面设置字体状态)(UITextAttributeTextColor已过时)

  [firstItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIColor grayColor], UITextAttributeTextColor, nil] forState:UIControlStateNormal];

 //设置图片(选中和未选中)(此方法也已过时)
 [firstItem setFinishedSelectedImage:[UIImage imageNamed:@"local"] withFinishedUnselectedImage:[UIImage imageNamed:@"localClick"]];

#import "MyTabBar.h"

@implementation MyTabBar

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        //通过三原色设置背景颜色
        self.backgroundColor = [UIColor colorWithRed:/250.0f green:/250.0f blue:/250.0f alpha:];
    }
    return self;
}

// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
    // Drawing code
}
