某些地方可能会将 CGFLOAT_MIN 作为一个数值参与计算（但其实 CGFLOAT_MIN 更应该被视为一个标志位而不是数值），可能导致一些精度问题，所以提供这个方法快速将 CGFLOAT_MIN 转换为 0 issue: https://github.com/Tencent/QMUI_iOS/issues/203
Declaration
Objective-C
static inline CGFloat removeFloatMin(CGFloat floatValue)Swift
func removeFloatMin(_ floatValue: CGFloat) -> CGFloat -
基于指定的倍数，对传进来的 floatValue 进行像素取整。若指定倍数为0，则表示以当前设备的屏幕倍数为准。
例如传进来 “2.1”，在 2x 倍数下会返回 2.5（0.5pt 对应 1px），在 3x 倍数下会返回 2.333（0.333pt 对应 1px）。
Declaration
Objective-C
static inline CGFloat flatSpecificScale(CGFloat floatValue, CGFloat scale)Swift

基于当前设备的屏幕倍数，对传进来的 floatValue 进行像素取整。
注意如果在 Core Graphic 绘图里使用时，要注意当前画布的倍数是否和设备屏幕倍数一致，若不一致，不可使用 flat() 函数，而应该用 flatSpecificScale

调整给定的某个 CGFloat 值的小数点精度，超过精度的部分按四舍五入处理。
例如 CGFloatToFixed(0.3333, 2) 会返回 0.33，而 CGFloatToFixed(0.6666, 2) 会返回 0.67
Warning
参数类型为 CGFloat，也即意味着不管传进来的是 float 还是 double 最终都会被强制转换成 CGFloat 再做计算Warning

func HasOverrideSuperclassMethod(_ targetClass: AnyClass!, _ targetSelector: Selector!) -> Bool -
如果 fromClass 里存在 originSelector，则这个函数会将 fromClass 里的 originSelector 与 toClass 里的 newSelector 交换实现。 如果 fromClass 里不存在 originSelecotr，则这个函数会为 fromClass 增加方法 originSelector，并且该方法会使用 toClass 的 newSelector 方法的实现，而 toClass 的 newSelector 方法的实现则会被替换为空内容
Warning
注意如果 fromClass 里的 originSelector 是继承自父类并且 fromClass 也没有重写这个方法，这会导致实际上被替换的是父类，然后父类及父类的所有子类（也即 fromClass 的兄弟类）也受影响，因此使用时请谨记这一点。因此建议使用 OverrideImplementation 系列的方法去替换，尽量避免使用 ExchangeImplementations。Declaration
Objective-C
static inline BOOL ExchangeImplementationsInTwoClasses(Class _fromClass, SEL _originSelector, Class _toClass, SEL _newSelector)Swift
func ExchangeImplementationsInTwoClasses(_ _fromClass: AnyClass!, _ _originSelector: Selector!, _ _toClass: AnyClass!, _ _newSelector: Selector!) -> BoolParameters
_fromClass要被替换的 class，不能为空
_originSelector要被替换的 class 的 selector，可为空，为空则相当于为 fromClass 新增这个方法
_toClass要拿这个 class 的方法来替换
_newSelector要拿 toClass 里的这个方法来替换 originSelector
Return Value
是否成功替换（或增加）
-
交换同一个 class 里的 originSelector 和 newSelector 的实现，如果原本不存在 originSelector，则相当于给 class 新增一个叫做 originSelector 的方法

static inline BOOL ExchangeImplementations(Class _class, SEL _originSelector, SEL _newSelector)Swift
func ExchangeImplementations(_ _class: AnyClass!, _ _originSelector: Selector!, _ _newSelector: Selector!) -> Bool -
用 block 重写某个 class 的指定方法
Declaration
Objective-C
static inline BOOL OverrideImplementation(Class targetClass, SEL targetSelector, id (^implementationBlock)(Class, SEL, IMP (^)(void)))Swift
func OverrideImplementation(_ targetClass: AnyClass!, _ targetSelector: Selector!, _ implementationBlock: ((AnyClass?, Selector?, (() -> IMP?)?) -> Any?)!) -> BoolParameters
targetClass要重写的 class
targetSelector要重写的 class 里的实例方法，注意如果该方法不存在于 targetClass 里，则什么都不做
implementationBlock该 block 必须返回一个 block，返回的 block 将被当成 targetSelector 的新实现，所以要在内部自己处理对 super 的调用，以及对当前调用方法的 self 的 class 的保护判断（因为如果 targetClass 的 targetSelector 是继承自父类的，targetClass 内部并没有重写这个方法，则我们这个函数最终重写的其实是父类的 targetSelector，所以会产生预期之外的 class 的影响，例如 targetClass 传进来 UIButton.class，则最终可能会影响到 UIView.class），implementationBlock 的参数里第一个为你要修改的 class，也即等同于 targetClass，第二个参数为你要修改的 selector，也即等同于 targetSelector，第三个参数是一个 block，用于获取 targetSelector 原本的实现，由于 IMP 可以直接当成 C 函数调用，所以可利用它来实现“调用 super”的效果，但由于 targetSelector 的参数个数、参数类型、返回值类型，都会影响 IMP 的调用写法，所以这个调用只能由业务自己写。
-
用 block 重写某个 class 的某个无参数且返回值为 void 的方法，会自动在调用 block 之前先调用该方法原本的实现。
Declaration
Objective-C
static inline BOOL ExtendImplementationOfVoidMethodWithoutArguments( Class targetClass, SEL targetSelector, void (^implementationBlock)(__kindof NSObject *))Swift
func ExtendImplementationOfVoidMethodWithoutArguments(_ targetClass: AnyClass!, _ targetSelector: Selector!, _ implementationBlock: ((NSObject?) -> Void)!) -> BoolParameters
targetClass要重写的 class
targetSelector要重写的 class 里的实例方法，注意如果该方法不存在于 targetClass 里，则什么都不做，注意该方法必须无参数，返回值为 void
implementationBlocktargetSelector 的自定义实现，直接将你的实现写进去即可，不需要管 super 的调用。参数 selfObject 代表当前正在调用这个方法的对象，也即 self 指针。

获取业务项目的所有 class
例如：
classref_t *classes = nil; int count = qmui_getProjectClassList(&classes); Class class = (__bridge Class)classes[0];Declaration
Objective-C
extern int qmui_getProjectClassList(classref_t **classes)Swift
func qmui_getProjectClassList(_ classes: UnsafeMutablePointer<UnsafeMutablePointer<classref_t?>?>!) -> Int32Parameters
classes传入 classref_t 变量的指针，会填充结果到里面，然后可以用下标访问。如果只是为了得到总数，可传入 NULL。
Return Value
class 的总数
