贴一段我很久以前写的小demo，你们就明白了，是把textField套在alertView里的
@interface ViewController : UIViewController <UIAlertViewDelegate, UITextFieldDelegate>{
UILabel *la;
UITextField *myTextField;
}
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
la = [[UILabel alloc] init];
la.Frame = CGRectMake(10, 150,300,30);
la.backgroundColor = [UIColor clearColor];
la.font = [UIFont fontWithName:@"Helvetica-Bold" size:20];
la.text = @"initLabel";
la.textAlignment = UITextAlignmentCenter;
la.shadowColor = [UIColor colorWithWhite:0.0f alpha:0.75f];
la.shadowOffset = CGSizeMake(0.0f, 5.0f);
la.textColor = [UIColor greenColor];
[self.view addSubview:la];
UIButton *alartBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
alartBtn.frame = CGRectMake(110, 50, 50, 50);
alartBtn.backgroundColor = [UIColor clearColor];
[alartBtn setTitle:@"alart" forState:UIControlStateNormal];
[alartBtn addTarget:self action:@selector(alartShow:) forControlEvents:UIControlEventTouchUpInside];
[alartBtn setAlpha:1.0];
[self.view addSubview:alartBtn];
}
-(void)alartShow:(id)sender{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Title" message:@" " delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"OK", nil];
[alert show];
[alert release];
myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[alert addSubview:myTextField];
[myTextField setDelegate:self];
[myTextField addTarget:self action:@selector(onTextFieldChanged:forEvent:) forControlEvents:UIControlEventEditingChanged];
NSLog(@"myTextField.text:%@", myTextField.text);
}
- (void)alertView: (UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex {
{
NSLog(@"%@", myTextField.text);
la.text = myTextField.text;
}
}
- (void)alertView:(UIAlertView *)alert didDismissWithButtonIndex:(NSInteger)buttonIndex{
if (buttonIndex == [alert cancelButtonIndex]) {
close(0);
}
}
- (void) onTextFieldChanged:(id)sender forEvent:(UIEvent *)event{
NSLog(@"%@", myTextField.text);
}
摘出来的，大概意思应该已经有了，有用的自己在看下。。。欢迎技术交流，彼此进步。。谢谢。。
