2. .m内容

- (CGPoint)origin{
    return self.frame.origin;
}
- (void)setOrigin:(CGPoint)origin{
    CGRect frame = self.frame;
    frame.origin = origin;
    self.frame = frame;
}

- (CGSize)size{
    return self.frame.size;
}
- (void)setSize:(CGSize)size{
    CGRect frame = self.frame;
    frame.size = size;
    self.frame = frame;
}

- (CGFloat)x{
    return self.frame.origin.x;
}
- (void)setX:(CGFloat)x{
    CGRect frame = self.frame;
    frame.origin.x = x;
    self.frame = frame;
}

- (CGFloat)y{
    return self.frame.origin.y;
}
- (void)setY:(CGFloat)y{
    CGRect frame = self.frame;
    frame.origin.y = y;
    self.frame = frame;
}

- (CGFloat)width{
    return self.frame.size.width;
}
- (void)setWidth:(CGFloat)width{
    CGRect frame = self.frame;

    self.frame = frame;
}

- (CGFloat)height{
    return self.frame.size.height;
}
- (void)setHeight:(CGFloat)height{
    CGRect frame = self.frame;
    frame.size.height = height;
    self.frame = frame;
}

- (CGFloat)bottom{
    return self.frame.origin.y + self.frame.size.height;
}
- (void)setBottom:(CGFloat)bottom{
    CGRect frame = self.frame;
    frame.origin.y = bottom - self.frame.size.height;
    self.frame = frame;
}
