我无法从我的 alertView 获取 textView 的值

UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 100)];

    [textView setText:@""];

    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"put text\n\n\n\n\n\n" message:@"" delegate:self cancelButtonTitle:@"Annuler" otherButtonTitles:@"Envoyer",nil];
    av.alertViewStyle = UIAlertViewStyleDefault;
    [av addSubview:textView];
    [av show];

它显示带有textview的alertview视图，它很好，我想获得textview的值

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {        
}

你能帮我吗

声明 textView 以供整个班级使用

@implementation objectTables
{
    UITextView *textView;
}

然后在你的

textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 100)];

    [textView setText:@""];

    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Push Notification\n\n\n\n\n\n" message:@"" delegate:self cancelButtonTitle:@"Annuler" otherButtonTitles:@"Envoyer",nil];
    av.alertViewStyle = UIAlertViewStyleDefault;
    [av addSubview:textView];
    [av show];

和

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {     

   NSString *textViewText = [textView text];

}

您可以使用- (UITextField *)textFieldAtIndex:(NSInteger)textFieldIndex ，它将返回UITextField的对象。

并从UITextField中获取文本。

或者另一种方式是

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{


UITextField *TextField = (UITextField *)[alertView viewWithTag:YOURTAG];
}

你可以试试这个：

UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 100)];
[textView setText:@""];
textView.tag = 10;
UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"put text\n\n\n\n\n\n" message:@"" delegate:self cancelButtonTitle:@"Annuler" otherButtonTitles:@"Envoyer",nil];
av.alertViewStyle = UIAlertViewStyleDefault;
[av addSubview:textView];
[av show];

在代表

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
      UITextView *textView = (UITextView *) [alertView viewWithTag:10];
      NSString *yourText = textView.text;       
}

只需UITextView在 .h 文件中声明您的

UITextView *textView;

并在 .m 文件中

textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 100)];

    [textView setText:@""];

    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"put text\n\n\n\n\n\n" message:@"" delegate:self cancelButtonTitle:@"Annuler" otherButtonTitles:@"Envoyer",nil];
    av.alertViewStyle = UIAlertViewStyleDefault;
    [av addSubview:textView];
    [av show];

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex 
{
//Gives you the Value of UITextView
        NSLog(@"%@",[textView text]); 
}

或者您可以将其定义为Extended class（.m 文件）中的属性并访问它。

@Interface yourINterfaceName()
{
@property(nonatomic , retain ) UITextView *textView;
}

试试这个

UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 100)];

[textView setText:@""];
textView.tag =10;
UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"put text\n\n\n\n\n\n" message:@"" delegate:self cancelButtonTitle:@"Annuler" otherButtonTitles:@"Envoyer",nil];
av.alertViewStyle = UIAlertViewStyleDefault;
[av addSubview:textView];
[av show];



- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{

 UITextView *textView = (UITextView *)[alertView viewWithTag:10];
  NSLog(@"%@",[textView text]); 

}
