创建到NSMutableArray时动态计算TextField [英] calculate dynamically TextField when created to an NSMutableArray

问题描述

我正在动态创建文本字段并对其进行加减...

i am creating the textfield dynamically and adding and subtracting them...

如何在同一循环中从两个不同数组中计算并选择值?

How to calculate and pick the value from two diffrent array on a same loop?

类似的东西

例如:for(UITextField * textFieldArray&& textFieldArray2中的字段)

eg: for(UITextField *field in textFieldArray && textFieldArray2)

我必须减去该值，并且我有2个数组，我想从不同数组但相同索引中减去两个文本字段的值...

i have to subtract the value and i have 2 Array and i want to subtract the value of two textfield from different array but same index...

我的代码是

int result = 0;
for(UITextField *field in textFieldArray) // will iterate all UITextField which was added
{
result += [field.text intValue]; //or floatValue
}
NSLog(@"the result is %d", result); //here you have sum of all the text fields' text

我想减去这个值，但是两个文本字段都在不同的数组上，但是具有相同的索引...

i want to subtract this but both text fields are on different Array but have same index...

int y12=([Txt_New_Actual.text intValue]);
float c116= y12-([Txt_New_Estimated.text floatValue]);
Txt_New_ONU.text = [[NSString alloc] initWithFormat:@"%.2f",c116];

推荐答案

您可以这样做.取一个变量进行相同的迭代

You could do it this way. Take one variable to iterate in common as

UITextField *fieldArray1=nil,*fieldArray2=nil;
for(int i =0;i<textFieldArray1.count;i++)
{
     fieldArray1 = [textFieldArray1 objectAtIndex:i]; //This is field in array1
     fieldArray2 = [textFieldArray2 objectAtIndex:i]; //This is field in array2 and both are at same index.

     //Do your operation here...
}
