{ 
    self.centimeterTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];

    [ptextfieldInches setBackgroundColor:[UIColor whiteColor]]; 

    [self.alertHeight addSubview:ptextfieldInches]; 

    [self.centimeterTextField setKeyboardType:UIKeyboardTypeDecimalPad]; 

    [self.ptextfieldInches setKeyboardType:UIKeyboardTypeDecimalPad]; 

    [self.ptextfield setKeyboardType:UIKeyboardTypeDecimalPad]; 

    self.alertHeight.tag=1;

，粘贴代码 –

是的，请张贴代码在这里 – Prashant

使用标签的正确textfild及其委托检查与巫Textfild呼吁。或者可能会忘记给三个TextFiled之一的代表进行正确检查。 –

- (void) presentSheet { 
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Enter Information" 
message:@"Specify the Name and URL" delegate:self cancelButtonTitle:@"Cancel"otherButtonTitles:@"OK", nil]; 

[alert addTextFieldWithValue:@"" label:@"Enter Name"]; 
[alert addTextFieldWithValue:@"http://" label:@"Enter URL"]; 

UITextField *tf = [alert textFieldAtIndex:0]; 
tf.clearButtonMode = UITextFieldViewModeWhileEditing; 
tf.keyboardType = UIKeyboardTypeAlphabet; 
tf.keyboardAppearance = UIKeyboardAppearanceAlert; 

tf.autocapitalizationType = UITextAutocapitalizationTypeWords; 
tf.autocorrectionType = UITextAutocorrectionTypeNo; 
// URL field 
tf = [alert textFieldAtIndex:1]; 
tf.clearButtonMode = UITextFieldViewModeWhileEditing; tf.keyboardType = UIKeyboardTypeURL; 
tf.keyboardAppearance = UIKeyboardAppearanceAlert; tf.autocapitalizationType = UITextAutocapitalizationTypeNone; tf.autocorrectionType = UITextAutocorrectionTypeNo; 
[alert show]; 
}

其不工作，没有声明addTextFieldWithValue显示。 – Youaregreat

@Youaregreat我建议参考iPhone Developer's Cookbook第9页。没有115 –

@ouaregreat这不是我开发的这段代码是从iPhone开发人员的食谱，这是ios初学者真的很好的来源。我个人每天都会提及它。 –

现在，您可以创建一个风格UIAlertView中。

UIAlertView中现在有一个属性 - alertViewStyle，你可以设置为枚举值之一

1 UIAlertViewStyleDefault

2. UIAlertViewStyleSecureTextInput

3 UIAlertViewStylePlainTextInput

4. UIAlertViewStyleLoginAndPasswordInput

一旦创建了警报视图，就可以设置它的样式并显示它。解除警报后，可以使用警报视图的textFieldAtIndex属性访问字段的内容。

要不然你也可以使用这一个，

IAlertView* dialog = [[UIAlertView alloc] init]; 
[dialog setDelegate:self]; 
[dialog setTitle:@"Enter Name"]; 
[dialog setMessage:@" "]; 
[dialog addButtonWithTitle:@"Cancel"]; 
[dialog addButtonWithTitle:@"OK"]; 

UITextField *nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; 
[nameField setBackgroundColor:[UIColor whiteColor]]; 
[dialog addSubview:nameField]; 
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 70.0); 
[dialog setTransform: moveUp]; 
[dialog show]; 
[dialog release]; 
[nameField release];

希望这个信息帮助。谢谢。

其良好的，但对我来说它不够的，因为我已经为米添加了三个文本字段，并转换成了字，并且在赋值的同时显示所有的值，我继续。 – Youaregreat
