关于UIAlertView with Textfield ... [英] About UIAlertView with Textfield...

问题描述

我有这个代码提示 UIAlertView ， UITextfield ：

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"New List Item", @"new_list_dialog")
                                                      message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:myTextField];
[myAlertView show];
[myAlertView release];

但是我想在用户点击确定后添加一个获取文本字段值，并且用户点击后，我想调用一个方法，如何将其分配给myAlertView？谢谢。

But I would like to add a get the textfield value, after the user click "OK", and after the user click , I want to call a method, how can I assign that to the myAlertView? Thank you.

推荐答案

将文本字段声明为global.And在alertView的方法中单击 - （void）alertView ：（UIAlertView *）actionSheet clickedButtonAtIndex：（NSInteger）buttonIndex 只需获取文本字段的值并使用它执行所需的操作.....

Declare the text field as global.And in the method of alertView clicked - (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex just take the value of the textfield and do the operations you want with it.....

继承修订后的代码

UITextField *myTextField;
...
{

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"New List Item", @"new_list_dialog")
                                                      message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:myTextField];
[myAlertView show];
[myAlertView release];
}
....
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"string entered=%@",myTextField.text);
}

对于iOS 5及更高版本
您可以使用 alertViewStyle 的属性> UIAlertView 。

For iOS 5 and later You can use alertViewStyle property of UIAlertView.
