当用户按下主 Storyboard 中的按钮时,我想显示包含标签和文本框以及确定按钮和取消按钮的消息框,并在用户按下 IOS 上的确定后获取文本框中的字符串?

我知道如何显示错误消息或类似的东西,但我不知道如何显示那样的消息框?

最佳答案

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Save"
message:@"Enter File Name"
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"OK", nil];

alertView.alertViewStyle = UIAlertViewStylePlainTextInput;

[alertView show];



- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
NSLog(@"Alert View dismissed with button at index %d",buttonIndex);

switch (alertView.alertViewStyle)
{
case UIAlertViewStylePlainTextInput:
{
UITextField *textField = [alertView textFieldAtIndex:0];
NSLog(@"Plain text input: %@",textField.text);
}
break;

case UIAlertViewStyleSecureTextInput:
{
UITextField *textField = [alertView textFieldAtIndex:0];
NSLog(@"Secure text input: %@",textField.text);
}
break;

case UIAlertViewStyleLoginAndPasswordInput:
{
UITextField *loginField = [alertView textFieldAtIndex:0];
NSLog(@"Login input: %@",loginField.text);

UITextField *passwordField = [alertView textFieldAtIndex:1];
NSLog(@"Password input: %@",passwordField.text);
}
break;

default:
break;
}
}
