前言
以后你的适配将可能是这样的
CGFloat value =
@(14)
.is5(15)
.is6(16)
.is7(17)
.is8(18)
.isX(20).floatValue;
如果机型为
iphone5 value=15，
iphone6 value=16，
iphone7 value=17，
iphone8 value=18，
iphoneX value=20，
其他返回14；
- 有时候，UI设计要求具体机型具体适配。但是三元表达式显得笨拙。
- 想要达到的效果就是：易懂、灵活。 思来想去想起了链式编程，点语法配置相应特殊机型的值。
- 由于与swift不同，OC的基本数据类型是真的基本数据类型，所以只能用NSNumber来包装。写NSNumber的分类
- 一般的设计图都是对应的是
iphone6的尺寸
• 1 想要了解，可以参考iOS尺寸单位pt、ppi与px之间换算关系 和IOS界面适配一: Pt与Px的关系
• 2 其实这些都没啥用，你只要记住 px 是像素点，pt是点，是长度计算单位。iphone 3 是1pt == 1px|iphone 4 到iphone 6是 1pt == 2px|iphone 6P + 是1pt == 3px
• 3 问题来了，如果你的图纸是不能提供pt尺寸的，那么就需要做一个px ->pt (下面将会说到)
示例
1. px->pt
在AppDelegate 中设置好图纸的宽高，以及图纸的scale
在后面的计算中，都会以这些为前提，进行px-pt换算
///图纸的宽度 默认是375pt
+ (void) setDrawingWidth: (CGFloat)w;
///图纸的高度 默认是667pt
+ (void) setDrawingHeight: (CGFloat)h;
/// 在 application:(UIApplication *)application didFinishLaunchingWithOptions 方法中调用
/**
* 图纸的点与分辨率的
* 分辨率 比例 比如 `iphone 6`是 (2px <=> 1pt) 所以，传入的值如果为px，那么scale为0.5;
* @warning 如果传入的是pt则不需要任何换算，则不用调用这个函数
@param scale 默认为1
*/
+ (void) setScale: (CGFloat) scale;
2. 点语法配置尺寸
如果iphone5 则返回10pt，iphoneX则返回30pt，其他机型返回20pt
CGFloat value = @(20).is5(10).isX(30).floatValue;
masonry 布局左右约束将会很方便。
UIView *view = [UIView new];
[self.view addSubview: view];
[view mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(@(12).is5(10));
make.right.equalTo(@(-12).is5(-10));
make.centerY.equalTo(self.view).offset(@(-12).isX(-20).floatValue);
make.height.equalTo(@(30).is5(20).isX(40));
}];
3. view距屏幕两边尺寸固定计算视图高度
这种需求很常见，于是封装了一个函数
/**
* 保证宽度左右距离屏幕边间距不变的情况下计算高度
* 图纸中的高度为10，宽度为20，返回实际高度
*
* CGFloat currentHeight = @(10).getHeightWithW(20);
* @return 实际高度
* @warning self为图纸的高度
* @warning 参数 为图纸宽度
* @bug 🌶 如果nil 调用 则会崩溃
*/
- (NSNumber * (^)(CGFloat)) getHeightWithW;
调用的含义:
- view 距离屏幕两边的距离要求固定，已知
view的图纸中宽度 为viewW，高度为viewH,求view实际的高度currentH
CGFloat currentH = @(viewH).getHeightWithW(viewW)
** .h**
#import <UIKit/UIKit.h>
//获取屏幕的宽,高
#define KWIDTH [UIScreen mainScreen].bounds.size.width
#define KHEIGHT [UIScreen mainScreen].bounds.size.height
/**
* 以下计算皆为pt(点) 如果需要 分辨率 换算
* 如果要是传入的值为px(像素)
* 在 application:(UIApplication *)application didFinishLaunchingWithOptions 方法中调用
* + (void) setScale: (CGFloat) scale;
*/

///图纸的宽度 默认是375pt
+ (void) setDrawingWidth: (CGFloat)w;
