多个UITextFields以编程方式添加，只有一个可以编辑

Question

我有一个问题，在一个UIView中添加多个UITextFields，它们被正确添加，但碰巧用户只能编辑它们中的第一个(触摸它，所以键盘出现)，我已经将委托设置为自我，并实现了textfieldbeginediting方法。遗憾的是，只有第一个反应触发了这个方法，其他的似乎是"不可触及的"。

你以前有过这种经历吗?

for (int i = 0;i<N;i++){

    CGRect textFieldNewFrame = CGRectMake(200,60 + 34*i,72,30);        
    fields[i] = [[UITextField alloc] initWithFrame:textFieldNewFrame];
    [fields[i] setTag:i];
    [fields[i] setText:@"0"];
    [fields[i] setFont:appFont];
    [fields[i] setTextColor:appColor];
    [fields[i] setBackground:[UIImage imageNamed:@"text_field_off.png"]];
    [fields[i] setTextAlignment:UITextAlignmentCenter];       
    [fields[i] setKeyboardType:UIKeyboardTypeDecimalPad];
    [fields[i] setDelegate:self];
    [fields[i] setUserInteractionEnabled:TRUE];
    [listView addSubview:fields[i]];
    verticalOffset += 34;
}

- (void)textFieldDidBeginEditing:(UITextField *)textField;{
    NSLog(@"TextField touched");
}

谢谢

我会这样做，这只是一个面向对象的答案，应该工作，已经为我工作了很多次。

NSMutableArray *fields=[[NSMutableArray alloc] init];
for (int i = 0;i<N;i++){       
CGRect textFieldNewFrame = CGRectMake(200,60 + 34*i,72,30);             
[fields  addObject:[[UITextField alloc] initWithFrame:textFieldNewFrame]];     
[[fields objectAtIndex:i] setTag:i];     
[[fields objectAtIndex:i] setText:@"0"];     
[[fields objectAtIndex:i] setFont:appFont];     
[[fields objectAtIndex:i] setTextColor:appColor];     
[[fields objectAtIndex:i] setBackground:[UIImage imageNamed:@"text_field_off.png"]];     
[[fields objectAtIndex:i] setTextAlignment:UITextAlignmentCenter];            
[[fields objectAtIndex:i] setKeyboardType:UIKeyboardTypeDecimalPad];     
[[fields objectAtIndex:i] setDelegate:self];     
[[fields objectAtIndex:i] setUserInteractionEnabled:TRUE];     
[listView addSubview:[fields objectAtIndex:i]];
verticalOffset += 34; }
