UITextField無法選擇

Question

我正在嘗試為正在使用的應用創建登錄屏幕。 現在我有兩個UITextField，它們后面有一個圖像視圖。 當我嘗試單擊文本字段以輸入文本時，什么也沒有發生。 我花了很多時間試圖找出這個問題，但是找不到遇到類似問題的人。 在我的LoginViewController的viewDidLoad方法中，我有以下代碼：

`

    [super viewDidLoad];
    UIImageView *splashView = [[UIImageView alloc] initWithFrame:self.view.frame];
    splashView.image = [UIImage imageNamed:@"Default-568h@2x.png"];

    UITextField *username = [[UITextField alloc] initWithFrame:CGRectMake(90, 320, 140, 30)];
    username.placeholder = @"username";
    username.borderStyle = UITextBorderStyleRoundedRect;
    username.returnKeyType = UIReturnKeyDone;
    username.textAlignment = NSTextAlignmentLeft;
    username.userInteractionEnabled = YES;
    [splashView addSubview:username];

    UITextField *password = [[UITextField alloc] initWithFrame:CGRectMake(90, 365, 140, 30)];
    password.placeholder = @"password";
    password.borderStyle = UITextBorderStyleRoundedRect;
    password.textAlignment = NSTextAlignmentLeft;
    [splashView addSubview:password];

    [self.view addSubview:splashView];
`

任何幫助或建議，將不勝感激，謝謝。

更改添加圖像的位置：

  [super viewDidLoad];
UIImageView *splashView = [[UIImageView alloc] initWithFrame:self.view.frame];
splashView.image = [UIImage imageNamed:@"Default-568h@2x.png"];

 // The image behind
 [self.view addSubview:splashView];

UITextField *username = [[UITextField alloc] initWithFrame:CGRectMake(90, 320, 140, 30)];
username.placeholder = @"username";
username.borderStyle = UITextBorderStyleRoundedRect;
username.returnKeyType = UIReturnKeyDone;
username.textAlignment = NSTextAlignmentLeft;
username.userInteractionEnabled = YES;
// Change this
[self.view addSubview:username];

UITextField *password = [[UITextField alloc] initWithFrame:CGRectMake(90, 365, 140, 30)];
password.placeholder = @"password";
password.borderStyle = UITextBorderStyleRoundedRect;
password.textAlignment = NSTextAlignmentLeft;
//And change this
[self.view addSubview:password];

如果您是另一個textField的另一個圖像，則首先添加視圖。
