如何獲得iPhone中的按鈕索引值？

Question

我已經創建了動態的按鈕。現在我想獲得按鈕索引值。

這裏我的代碼， 對於例如， 我的數組，

{ 
    one, 
    two, 
    three, 
    Four 
} 

int x = 10; 

for(int i = 0; i < [myArray count]; i++) { 

UIButton *answerBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 

[answerBtn setFrame:CGRectMake(30, x, 260, 40)]; 

answerBtn.tag = i; 

[answerBtn setTitle:[answerList objectAtIndex:i] forState:UIControlStateNormal]; 

NSString *actualString = @"two"; 

NSString *getString = [answerList objectAtIndex:i]; 

if([actualString isEqualToString:getString]) 
{ 

    //How do i get the correct values of array index, In this case i want to return the index value is 1. Bcoz the array[1] = two. 
    NSLog(@"The btn tag is %d", answerBtn.tag); // couldn't get correct index 
} 

[self.view addSubview: answerBtn]; 
} 

預期的結果是，

The btn tag is 1. 

Answer 1

NSLog(@"The btn tag is %d", answerBtn.tag); 

Answer 2

[answerBtn setFrame:CGRectMake(30, x, 260, 40)]; 

[answerBtn setTitle:[answerList objectAtIndex:i] forState:UIControlStateNormal]; 

NSString *actualString = @"two"; 

NSString *getString = [answerList objectAtIndex:i]; 

if([actualString isEqualToString:getString])

    //How do i get the correct button index, In this case i want to return the tag is 1. 
    NSLog(@"The btn tag is %d", answerBtn.tag); // it's not w
