动态计算文本字段时创建一个NSMutableArray

Question

我动态创建文本字段添加和减去它们...

如何计算并从两个不同势阵列挑值在同一个循环？

类似的东西

如：对（在textFieldArray & & textFieldArray2的UITextField *场）

我必须减去价值，我有2个阵列，我想从减去两个文本框的值不同的阵列，但相同的索引...

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 

我想减去此但两个文本字段在不同的阵列，但具有相同的索引...

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

Answer 1

您可以这样做。采取一个变量来共同迭代，因为

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... 
}
