NSEdgeInsetsとNSValueの変換

More than 5 years have passed since last update.

UIEdgeInsetsとNSEdgeInsetsはまったく同じ構造体なのだけど、宣言が別々なので困ることがあります。
UIKitのNSValueにはvalueWithUIEdgeInsets, UIEdgeInsetsValueメソッドがあるが、NSEdgeInsetsにはありません。

ハイ、そこでこんなカテゴリを作りました。

+ (instancetype)se_valueWithNSEdgeInsets:(NSEdgeInsets)insets
{
    return [NSValue valueWithBytes:&insets objCType:@encode(NSEdgeInsets)];
}

- (NSEdgeInsests)se_edgeInsetsValue
{
    NSEdgeInsets is = NSEdgeInsetsMake(0, 0, 0, 0);
    [self getValue:&is];
    return is;
}

果てしなく使いどころが無いと思います。
