核心代码：

#import "QHKeyboard.h"
#import "QHKeyboardNumPad.h"
#import "QHKeyboardWordPad.h"

#define iPhone4 ([[UIScreen mainScreen] bounds].size.height==480)
#define iPhone5 ([[UIScreen mainScreen] bounds].size.height==568)
#define iPhone6 ([[UIScreen mainScreen] bounds].size.height==667)
#define iPhone6plus ([[UIScreen mainScreen] bounds].size.height==736)

@interface QHKeyboard ()<QHKeyboardNumPadDelegate,QHKeyboardWordPadDelegate>

@property (nonatomic, weak) QHKeyboardNumPad *numPad;
@property (nonatomic, weak) QHKeyboardWordPad *wordPad;
