开发实用整理

• 自动补全目录，在文件写上 $(SRCROOT)

$(SRCROOT)/BiShe/PrefixHeader.pch

• 自定义分栏控制器 UITabBarController

@implementation BSTabBarController- (instancetype)init{    self = [super init];    if (self) {        // 统一设置Item的文字属性        [self setUpItemTextAttrs];        // 添加所以子控制器        [self setUpAllChildViewControllers];    }    return self;}- (void)viewDidLoad {    [super viewDidLoad];////     统一设置Item的文字属性//    [self setUpItemTextAttrs];//    //    // 添加所以子控制器//    [self setUpAllChildViewControllers];}/** *  统一设置Item文字的属性 */- (void)setUpItemTextAttrs{    // 统一设置Item文字的属性    // UI_APPEARANCE_SELECTOR    NSMutableDictionary *normalAttrs = [NSMutableDictionary dictionary];    normalAttrs[NSForegroundColorAttributeName] = [UIColor grayColor];    normalAttrs[NSFontAttributeName] = Font_20;    // 选中状态    NSMutableDictionary *selectAttrs = [NSMutableDictionary dictionary];    selectAttrs[NSForegroundColorAttributeName] = [UIColor blackColor];    UITabBarItem *item = [UITabBarItem appearance];    [item setTitleTextAttributes:normalAttrs forState:UIControlStateNormal];    [item setTitleTextAttributes:selectAttrs forState:UIControlStateSelected];}/** *  添加所有子控制器 */- (void)setUpAllChildViewControllers{    [self setUpOneViewController:[[BSHomeViewController alloc]init] title:@"首页" image:@"tabbar_home_nor" selectImage:@"tabbar_home_pre"];    [self setUpOneViewController:[[BSCategoryViewController alloc]init] title:@"分类" image:@"tabbar_category_nor" selectImage:@"tabbar_category_pre"];    [self setUpOneViewController:[[BSShopCartViewController alloc]init] title:@"购物车" image:@"tabbar_shoppingcart_nor" selectImage:@"tabbar_shoppingcart_pre"];    [self setUpOneViewController:[[BSAccountViewController alloc]init] title:@"个人中心" image:@"tabbar_mine_nor" selectImage:@"tabbar_mine_pre"];}/** *  添加一个子控制器 */- (void)setUpOneViewController:(UIViewController *)vc title:(NSString *)title image:(NSString *)image selectImage:(NSString *)selectImage{    if ([title isEqualToString:@"首页"]) {        UIImageView * imageView = [[UIImageView alloc] init];        imageView.frame = CGRectMake(0, 0, 40, 40);        [imageView setImage:[UIImage imageNamed:@"home_logo"]];        vc.navigationItem.titleView = imageView;    }    vc.title = title;    vc.tabBarItem.image = [UIImage imageNamed:image];    vc.tabBarItem.selectedImage = [UIImage imageNamed:selectImage];    BSNavigationController *nav = [[BSNavigationController alloc]initWithRootViewController:vc];    [self addChildViewController:nav];}

• 继承UINavigationController的BSNavigationController，自定义导航栏，包括返回按钮，右滑返回手势

@interface BSNavigationController ()<UIGestureRecognizerDelegate>@end@implementation BSNavigationController- (void)viewDidLoad {    [super viewDidLoad];    // 设置pop手势代理    self.interactivePopGestureRecognizer.delegate = self;}/** *  统一设置左上角返回图片 */- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{    if (self.childViewControllers.count > 0) {        /* 自动显示和隐藏tabbar */        viewController.hidesBottomBarWhenPushed = YES;        // 设置左边的返回按钮        viewController.navigationItem.leftBarButtonItem = [UIBarButtonItem itemWithTarget:self action:@selector(blackBtnClick) image:@"commom_back" highImage:@"commom_back"];    }    [super pushViewController:viewController animated:animated];}- (void)blackBtnClick{    [self popViewControllerAnimated:YES];}#pragma mark -- 点击空白处收起键盘-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{    [super touchesBegan:touches withEvent:event];    [self.view endEditing:YES];}#pragma mark - <UIGestureRecognizerDelegate>/** *  push进来的控制器大于1个，手势有效 */- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{    return self.viewControllers.count > 1;}@end

• 导航字体设置

[self.navigationController.navigationBar setTitleTextAttributes:@{NSFontAttributeName:Font_30,NSForegroundColorAttributeName:Color_2F2F2F}];

---

• 打印调试

#if DEBUG#define DR_NSLog(fmt,...)    NSLog((@"%s [Line %d] " fmt),__PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);  /**<输出语句*/#else#define DR_NSLog(fmt, ...)#endif

• 屏幕尺寸判断

// 判断 iPhone4s#define kiPhone4 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) : NO)// 判断 iPhone5#define kiPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)// 判断iphone6#define kiPhone6 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen] currentMode].size) : NO)// 判断iphone6+#define kiPhone6Plus ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2208), [[UIScreen mainScreen] currentMode].size) : NO)

• 随机色

#define BSColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]#define BSRandomColor BSColor(arc4random_uniform(255), arc4random_uniform(255), arc4random_uniform(255))

• 重写UIBarButtonItem 分栏标题与图片

/** *  创建一个item * *  @param target    点击item后调用哪个对象的方法 *  @param action    点击item后调用target的哪个方法 *  @param image     图片 *  @param highImage 高亮的图片 * *  @return 创建完的item */+ (UIBarButtonItem *)itemWithTarget:(id)target action:(SEL)action image:(NSString *)image highImage:(NSString *)highImage{    UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];    [btn addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];    // 设置图片    [btn setImage:[UIImage imageNamed:image] forState:UIControlStateNormal];    [btn setImage:[UIImage imageNamed:highImage] forState:UIControlStateHighlighted];    [btn setImageEdgeInsets:UIEdgeInsetsMake(0, -5, 0, 30)];    // 设置尺寸    btn.size = CGSizeMake(60, 44);//btn.currentBackgroundImage.size;    return [[UIBarButtonItem alloc] initWithCustomView:btn];}
