我正在尝试以简单的方式修改模板,而不是重写底层代码。我意识到通常对象分配不是在模板中完成的,但有可能吗?
我想要这样的事情:
- (UIColor *)colorFromColor:(UIColor *)fromColor toColor:(UIColor *)toColor percent:(float)percent
{
float dec = percent / 100.f;
CGFloat fRed, fBlue, fGreen, fAlpha;
CGFloat tRed, tBlue, tGreen, tAlpha;
CGFloat red, green, blue, alpha;
if(CGColorGetNumberOfComponents(fromColor.CGColor) == 2) {
[fromColor getWhite:&fRed alpha:&fAlpha];
fGreen = fRed;
fBlue = fRed;
}
else {
[fromColor getRed:&fRed green:&fGreen blue:&fBlue alpha:&fAlpha];
}
if(CGColorGetNumberOfComponents(toColor.CGColor) == 2) {
[toColor getWhite:&tRed alpha:&tAlpha];
tGreen = tRed;
tBlue = tRed;
}
else {
[toColor getRed:&tRed green:&tGreen blue:&tBlue alpha:&tAlpha];
}
red = (dec * (tRed - fRed)) + fRed;
green = (dec * (tGreen - fGreen)) + fGreen;
blue = (dec * (tBlue - fBlue)) + fBlue;
alpha = (dec * (tAlpha - fAlpha)) + fAlpha;
return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
}
我想阅读对象变量$ product-> available_now,并根据其内容将其更新为其他内容,以便稍后在模板中使用。
我尝试的所有内容都以空白屏幕或其他方式结束(如上面的代码所示)是一个未更改的变量。
仅供参考:这适用于prestashop

尝试:
{if $product->available_now == "XXX001"}
{assign var=product->available_now value="YYY123"}
{/if}

我必须承认我没有测试过,但它必须是你犯的错误,因为这是为变量赋值的正确方法!
