將UITextField的文本放入UIAlertView

Question

我正在嘗試將文本字段中的文本放入UIAlertView中，但未顯示。 它只是顯示空白。

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Kik" message:self.kik.text delegate:self cancelButtonTitle:@"Got it!" otherButtonTitles: nil];

[alert show];

Answer 1

你應該試試，

if ( [self.kik.text length])
{
UIAlertView *alert = [UIAlertView alloc]initWithTitle:@"Kik" message:[NSString stringWithFormat:@"%@",self.kik.text] delegate:self cancelButtonTitle:@"Got it!" otherButtonTitles: nil];

[alert show];
}
else
{
UIAlertView *alert = [UIAlertView alloc]initWithTitle:@"Kik" message:@"Please enter a valid string" delegate:self cancelButtonTitle:@"Got it!" otherButtonTitles: nil];

[alert show];

}

校驗..
