ios - 如何从NSMutableArray中获取float的总和

问题描述

我创建了一个NSMutableArray，它包含很多NSString和float

I created a NSMutableArray which contains a lot of NSString and float

DataOrder *addClient = [[DataOrder alloc ] initWithName:[[DataOrder instance]product] price:[[DataOrder instance]price] taille:[[DataOrder instance]taille] suplement:[[DataOrder instance]suplement]];
[[[ArrayBuying instance] tableau]addObject:addClient];

我在数组中添加对象[[ArrayBuying instance] tableau]

I add the object in my array "[[ArrayBuying instance] tableau]"

如何获得浮点变量的总和？

How can I get the total sum of the float variables ?

谢谢

推荐答案

这样的事情会起作用：

float total = 0;
for (DataOrder *client in [[ArrayBuying instance] tableau]) {
    total += client.price;
}

NSLog(@"total = %f", total);

我只是猜测你的 DataOrder class有价格属性。使用你真正拥有的东西。

I'm just guessing that your DataOrder class has a price property. Use what you really have.
