IOS - 常用代码块收集

收集常用的代码块是加快开发的有效途径，收集的操作步骤这里不在赘述，仅仅贡献上一些常用的功能性代码

1、与高度和宽度有关的

    /*获取导航栏高度*/
    public func getNavigationBarHeight() -> CGFloat {
        let navRect:CGRect! = self.navigationController?.navigationBar.frame
        return navRect.size.height
    }
    /*获取标签栏高度*/
    public func getTabBarHeight() -> CGFloat {
        let tabBarRect:CGRect! = self.tabBarController?.tabBar.frame
        return tabBarRect.size.height
    }
    /*获取状态栏高度*/
    public func getStatusBarHeight() -> CGFloat {
        let rectStatus:CGRect = UIApplication.shared.statusBarFrame
        return rectStatus.size.height
    }

    /*根据提供的字体大小，宽度获取字文字的高度*/
    func getTextHeigh(textStr:String,font:UIFont,width:CGFloat) -> CGFloat {
        let normalText: NSString = textStr as NSString
        let size = CGSize(width: width, height: 10000)
        let dic:NSDictionary = NSDictionary(object: font, forKey: NSAttributedStringKey.font as NSCopying)
        let stringSize = normalText.boundingRect(with: size, options: .usesLineFragmentOrigin, attributes: dic as? [NSAttributedStringKey : Any], context:nil).size
        return stringSize.height
    }
    
    /*提供文字大小，控件高度，获取到文字的宽度*/
    func getTexWidth(textStr:String,font:UIFont,height:CGFloat) -> CGFloat {
        let normalText: NSString = textStr as NSString
        let size = CGSize(width: 10000, height: height)
        let dic:NSDictionary = NSDictionary(object: font, forKey: NSAttributedStringKey.font as NSCopying)
        let stringSize = normalText.boundingRect(with: size, options: .usesLineFragmentOrigin, attributes: dic as? [NSAttributedStringKey : Any], context:nil).size
        return stringSize.width + 40
    }

    UIScreen.main.bounds.size.width // 屏幕宽度
    UIScreen.main.bounds.size.height // 屏幕高度


    /*UIFont的适配(创建UIFont的扩展)*/
+ (void)load {
    Method newMethod = class_getClassMethod([self class], @selector(adjustFont:));
    Method method = class_getClassMethod([self class], @selector(systemFontOfSize:));
    method_exchangeImplementations(newMethod, method);
}

+ (UIFont *)adjustFont:(CGFloat)fontSize {
    UIFont *newFont = nil;
    //BaseWidth 为设计图的尺寸
    newFont = [UIFont adjustFont:fontSize * [UIScreen mainScreen].bounds.size.width / BaseWidth];
    return newFont;
}

                   blue: ((CGFloat)(rgbValue & 0xFF)) / 255.0,
                   alpha: 1.0)

    }

    }

}
