总结工作中一些常用的公共类

在工作当中经常要写一些公共的类，所以在这里做一个小小的总结，下面是代码

PublicCell，主要用于定义背景颜色

点h

#import <UIKit/UIKit.h>@interface PublicCell : UITableViewCell@property (nonatomic ,strong)UIView *selectView;@end

点m

#import "PublicCell.h"@implementation PublicCell- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];    if (self) {                //定义原来的背景颜色为空        self.selectionStyle = UITableViewCellSelectionStyleNone;                //自定义想要的颜色，一开始将背景颜色设置为空        _selectView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 44)];        _selectView.backgroundColor = RGBCOLOR(234, 215, 184);        _selectView.alpha = 0.0;                [self.contentView addSubview:_selectView];            }    return self;}- (void)showBackGroundColor{        [UIView beginAnimations:nil context:nil];    [UIView setAnimationDuration:1];    _selectView.alpha = kAlpha;    _selectView.alpha = 0.0;    [UIView commitAnimations];    }//点击cell的时候触发方法- (void)setSelected:(BOOL)selected animated:(BOOL)animated{    [super setSelected:selected animated:animated];        if (selected)    {        [self showBackGroundColor];    }    }

PublicNavigationController，定义bar

点m

- (void)viewDidLoad{    [super viewDidLoad];//自定义bar背景    [self.navigationBar setBackgroundImage:[UIImage imageNamed:@"topbar"] forBarMetrics:UIBarMetricsDefault];}

PublicTabBarController，自定义整个tabBar，代码较多

点h

#import <UIKit/UIKit.h>#import "PublicNavigationController.h"//代理，当点击bar的时候触发@protocol PublicTabBarControllerDelegate <NSObject>@optional-(void)didSelectTabBarWithIndex:(int)index;@end@interface PublicTabBarController : UITabBarController{@private    UIImageView *_tabBarBG;    }@property(nonatomic,strong)PublicNavigationController *moreNav;@property(nonatomic,unsafe_unretained)id<PublicTabBarControllerDelegate>Odelegate;//显示bar的方法- (void)showTabBar;//隐藏bar的方法- (void)hiddenTabBar;@end

点m

@interface PublicTabBarController ()@end@implementation PublicTabBarController- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];    if (self) {        // Custom initialization    }    return self;}- (void)viewDidLoad{    [super viewDidLoad];        [self performSelector:@selector(loadViewControllers)];        [self performSelector:@selector(loadCustomTabBarView)];    }//加载视图- (void)loadViewControllers{        OnLineViewController *onLineVC = [[OnLineViewController alloc]initWithNibName:@"OnLineViewController" bundle:nil];    self.Odelegate = onLineVC;    PublicNavigationController *onLineNav = [[PublicNavigationController alloc]initWithRootViewController:onLineVC];        DownLoadViewController *downLoadVC = [[DownLoadViewController alloc]initWithNibName:@"DownLoadViewController" bundle:nil];    self.Odelegate = downLoadVC;    PublicNavigationController *downLoadNav = [[PublicNavigationController alloc]initWithRootViewController:downLoadVC];        MoreViewController *moreVC = [[MoreViewController alloc]initWithNibName:@"MoreViewController" bundle:nil];        _moreNav = [[PublicNavigationController alloc]initWithRootViewController:moreVC];        NSArray *viewControllers = @[onLineNav, downLoadNav, _moreNav];        [self setViewControllers:viewControllers animated:YES];    }//创建自定义背景- (void)loadCustomTabBarView{        // 初始化自定义TabBar背景    if (iPhone5) {        _tabBarBG = [[UIImageView alloc] initWithFrame:CGRectMake(0, 516, 320, 52)];    }else{        _tabBarBG = [[UIImageView alloc] initWithFrame:CGRectMake(0, 480-52, 320, 52)];    }        _tabBarBG.userInteractionEnabled = YES;    _tabBarBG.image = [UIImage imageNamed:@"deepbar"];    [self.view addSubview:_tabBarBG];        NSArray *selectArray = @[@"home press",@"download press",@"more press"];    NSArray *normalArray = @[@"home normal",@"download normal",@"more normal"];        // 初始化自定义TabBarItem -> UIButton    float coordinateX = 0;    for (int index = 0; index < 3; index++) {                UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];                button.frame = CGRectMake(-1+coordinateX, 3 , 107, 49);                [button setBackgroundImage:[UIImage imageNamed:[normalArray objectAtIndex:index]] forState:UIControlStateNormal];        [button setBackgroundImage:[UIImage imageNamed:[selectArray objectAtIndex:index]] forState:UIControlStateSelected];                [button addTarget:self action:@selector(changeViewController:) forControlEvents:UIControlEventTouchUpInside];                button.tag = index+100;                [_tabBarBG addSubview:button];                coordinateX += 107;    }        UIButton *btn1 = (UIButton *)[self.view viewWithTag:100];    btn1.selected = YES;}- (void)changeViewController:(UIButton *)button{    UIButton *btn1 = (UIButton *)[self.view viewWithTag:100];    UIButton *btn2 = (UIButton *)[self.view viewWithTag:101];    UIButton *btn3 = (UIButton *)[self.view viewWithTag:102];        self.selectedIndex = button.tag-100;    button.selected = YES;        //判断选中状态    switch (button.tag-100) {        case 0:{            btn1.selected = YES;            btn2.selected = NO;            btn3.selected = NO;            if ([self.Odelegate respondsToSelector:@selector(didSelectTabBarWithIndex:)]) {                [self.Odelegate didSelectTabBarWithIndex:button.tag];            }        }            break;        case 1:{            btn1.selected = NO;            btn2.selected = YES;            btn3.selected = NO;            if ([self.Odelegate respondsToSelector:@selector(didSelectTabBarWithIndex:)]) {                [self.Odelegate didSelectTabBarWithIndex:button.tag];            }        }            break;        case 2:{            btn1.selected = NO;            btn2.selected = NO;            btn3.selected = YES;        }            break;                    default:            break;    }            }- (void)showTabBar{    [UIView beginAnimations:nil context:NULL];    [UIView setAnimationDuration:0.34];    if (iPhone5) {        _tabBarBG.frame = CGRectMake(0, 516, 320, 52);    }else{        _tabBarBG.frame = CGRectMake(0, 480-52, 320, 52);    }    [UIView commitAnimations];}- (void)hiddenTabBar{    [UIView beginAnimations:nil context:NULL];    [UIView setAnimationDuration:0.35];    if (iPhone5) {        _tabBarBG.frame = CGRectMake(-320, 516, 320, 52);    }else{        _tabBarBG.frame = CGRectMake(-320, 480-52, 320, 52);    }    [UIView commitAnimations];}
