这是我必须创建带有文本框的 UIAlertView 的代码。
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter A Username Here" message:@"this gets covered!"
delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60);
[alert setTransform:myTransform];
alert.tag = kAlertSaveScore;
[myTextField setBackgroundColor:[UIColor whiteColor]];
[alert addSubview:myTextField];
[alert show];
[alert release];
[myTextField release];
我的问题是,如何从文本字段中获取值:
- (void) alertView:(UIAlertView *) actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
}
我知道我可以获得警报视图的标准内容,例如 actionSheet.tag 等,但是我如何获得上面创建的文本字段?
@interface MyClass {
UITextField *alertTextField;
}
@end
并且不用在本地声明它,而是使用它。
//...
alertTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
//...
- (void) alertView:(UIAlertView *) alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString *text = alertTextField.text;
alertTextField = nil;
}
