OC项目中常用的宏定义

做项目常用的宏定义梳理(pch)

一、屏幕宽高的宏

// 屏幕rect
#define SCREEN_BOUNDS ([UIScreen mainScreen].bounds)
// 屏幕宽度
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
// 屏幕高度
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)
// 屏幕分辨率
#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))

二、屏幕顶部安全高度的宏及机型判断

// iPhoneX系列判断
#define IS_iPhoneX [UIScreen mainScreen].bounds.size.height >= 812.f
#define mIsiP6 ([UIScreen mainScreen].bounds.size.height == 667.0)
#define mIsiP6P ([UIScreen mainScreen].bounds.size.height == 736.0)
// 顶部安全区域高度
#define StatusBarSafeTopMargin (IS_iPhoneX ? 24.f : 0.f)
// 底部安全区域高度
#define TabbarSafeBottomMargin (IS_iPhoneX ? 34.f : 0.f)
// 顶部状态栏高度
#define StatusBarHeight (IS_iPhoneX ? 44.f : 20.f)
// 导航栏高度
#define NavBarHeight (44.f+StatusBarHeight)
// 底部标签栏高度
#define TabBarHeight (IS_iPhoneX ? (49.f+34.f) : 49.f)

三、字体宏

//字体设置
#define ZA_FontSize(value) [UIFont systemFontOfSize:value]
#define ZAFont_PF_Light(fontSize) [UIFont fontWithName:@"PingFangSC-Light" size:fontSize]
#define ZAFont_PF_Ultralight(fontSize) [UIFont fontWithName:@"PingFangSC-Ultralight" size:fontSize]
// 苹方常规
#define ZAFont_PF_Regular(fontSize) [UIFont fontWithName:@"PingFangSC-Regular" size:fontSize]
// 苹方粗体                                           
#define ZAFont_PF_Semibold(fontSize) [UIFont fontWithName:@"PingFangSC-Semibold" size:fontSize]
#define ZAFont_PF_Thin(fontSize) [UIFont fontWithName:@"PingFangSC-Thin" size:fontSize]
#define ZAFont_PF_Medium(fontSize) [UIFont fontWithName:@"PingFangSC-Medium" size:fontSize]

使用例子:

-(UILabel *)watchNumLabel
{
    if (!_watchNumLabel) {
        _watchNumLabel = [[UILabel alloc] init];
        _watchNumLabel.textColor = RGB_HEX(0x999999, 1);
        _watchNumLabel.textAlignment = NSTextAlignmentRight;
        _watchNumLabel.font = ZAFont_PF_Regular(12);
    }
    
    return _watchNumLabel;
}

四、判断当前iOS版本

//判断当前iOS版本
#define IOS_VERSION [UIDevice currentDevice].systemVersion

五、颜色RGB

#define RGB_GGCOLOR(r,g,b) [UIColor colorWithRed:(r) / 255.0f green:(g) / 255.0f blue:(b) / 255.0f alpha:(1.0)]
#define RGBA_GGCOLOR(r,g,b,p) [UIColor colorWithRed:(r) / 255.0f green:(g) / 255.0f blue:(b) / 255.0f alpha:(p)]
// 形如 RGB_HEX(0xFDFDFD, 1.0f) 的颜色定义
#define RGB_HEX(rgbValue, a) \
    [UIColor colorWithRed:((CGFloat)((rgbValue & 0xFF0000) >> 16)) / 255.0 \
                    green:((CGFloat)((rgbValue & 0xFF00) >> 8)) / 255.0 \
                     blue:((CGFloat)(rgbValue & 0xFF)) / 255.0 \
                    alpha:(a)]

使用例子:

 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setFrame:CGRectMake(SCREEN_WIDTH - 70, SCREEN_HEIGHT - 134, 60, 60)];
    [button setBackgroundColor:RGB_GGCOLOR(86, 202, 252)];
    button.layer.masksToBounds = YES;
    button.layer.cornerRadius  = 30;
    [button setTitle:@"导航" forState:UIControlStateNormal];
    [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(openNaviApp:) forControlEvents:UIControlEventTouchUpInside];
    [self .view addSubview:button];

六、非空判断

#define IsNilOrNull(_ref)   (((_ref) == nil) || ([(_ref) isEqual:[NSNull null]]))
//字符串是否为空
#define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO )
//数组是否为空
#define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0)
//字典是否为空
#define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0)
//是否是空对象
#define kObjectIsEmpty(_object) (_object == nil \
|| [_object isKindOfClass:[NSNull class]] \
|| ([_object respondsToSelector:@selector(length)] && [(NSData *)_object length] == 0) \
|| ([_object respondsToSelector:@selector(count)] && [(NSArray *)_object count] == 0))

使用例子:

 if (!kStringIsEmpty(_model.insid)) {
        HomeServiceTrainDetailVC *detailVC = [HomeServiceTrainDetailVC new];
        detailVC.insId = _model.insid;
        [self.navigationController pushViewController:detailVC animated:YES];
    }
