NSValue包装对象指针，CGRect结构体等

@interface NSValue (NSValueUIGeometryExtensions)
  
+ (NSValue *)valueWithPointer:(const void *)pointer;//保存对象指针
 
+ (NSValue *)valueWithCGPoint:(CGPoint)point;//保存CGPoint结构体
+ (NSValue *)valueWithCGSize:(CGSize)size;//保存CGSize结构体
+ (NSValue *)valueWithCGRect:(CGRect)rect;//保存CGRect结构体
+ (NSValue *)valueWithCGAffineTransform:(CGAffineTransform)transform;
+ (NSValue *)valueWithUIEdgeInsets:(UIEdgeInsets)insets;
  
- (void *)pointerValue;
- (CGPoint)CGPointValue;
- (CGSize)CGSizeValue;
- (CGRect)CGRectValue;
- (CGAffineTransform)CGAffineTransformValue;
- (UIEdgeInsets)UIEdgeInsetsValue;
  
@end

偶就抽三个来写吧。。其它的方式差不多。。。
