UITextField
的UIAlertView
。我想要在UIAlertView
的ok按钮中输入邮件ID并提交,但是UIAlertView
中的UITextField
没有响应。请帮助我。iOS 5 开始,上述方法已不再必要。只需将 alertViewStyle
属性设置为适当的样式(UIAlertViewStyleSecureTextInput
、UIAlertViewStylePlainTextInput
或 UIAlertViewStyleLoginAndPasswordInput
)即可。
示例:
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Email" message:@"Enter your email:" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
你可以把响应作为返回值
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
UITextField *emailTextField = [alertView textFieldAtIndex:0];
NSLog(@"%@",emailTextField.text);
}
带有 UITextField
的 UIAlertView
:
NSString *title = NSLocalizedString(@"Your Title","");
NSString *placeholder = NSLocalizedString(@"Placeholder Text","");
NSString *message = NSLocalizedString(@"A message to the user.","");
NSString *cancel = NSLocalizedString(@"Cancel","");
NSString *okay = NSLocalizedString(@"Continue","");
prompt = [[AlertPrompt alloc] initWithTitle:title
placeholder:placeholder
message:message
delegate:self
cancelButtonTitle:cancel
okButtonTitle:okay];
[prompt show];
[prompt release];
#import <Foundation/Foundation.h>
@interface AlertPrompt : UIAlertView <UITextFieldDelegate>
{
UITextField *textField;
NSString *enteredText;
}
@property(nonatomic,retain) UITextField *textField;
@property (nonatomic, retain, readonly) NSString *enteredText;
- (id)initWithTitle:(NSString *)title placeholder:(NSString *)placeholder message:(NSString *)message delegate:(id)delegate
cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle;
@end
#import ".h"
@implementation AlertPrompt

cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle {
if (self = [super initWithTitle:title message:message delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])
{
self.title = title;
self.message = [NSString stringWithFormat:@"%@\n\n\n",message];
self.delegate = delegate;
UITextField *theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 75.0f, 260.0, 30.0)];
[theTextField setBackgroundColor:[UIColor clearColor]];
theTextField.borderStyle = UITextBorderStyleRoundedRect;
theTextField.textColor = [UIColor blackColor];
theTextField.font = [UIFont systemFontOfSize:18.0];
theTextField.autocapitalizationType = UITextAutocapitalizationTypeWords;

self.textField = theTextField;
[theTextField release];
CGAffineTransform translate = CGAffineTransformMakeTranslation(0, -10);
[self setTransform:translate];
}
return self;
}
- (void)show{
[textField becomeFirstResponder];
[super show];
}
- (NSString *)enteredText{
return textField.text;
}
- (void)dealloc{
[textField resignFirstResponder];
[textField release];
[super dealloc];
}
@end
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if([alertView.title isEqualToString:@"Your Title"])
{
if(buttonIndex == 1)
{
/* get the user iputted text */
NSString *inputValue = [(AlertPrompt *)alertView enteredText];
NSLog(@"User Input: %@",inputValue);
{
}
}
Swift 版本:
var alert = UIAlertView(title: "PostActionTitle", message: "PostActionText", delegate: self, cancelButtonTitle:"PostActionDecline")
alert.alertViewStyle = UIAlertViewStyle.PlainTextInput
alert.addButtonWithTitle("PostActionAccept")
alert.show()
UIAlertView *emailAlert=[[UIAlertView alloc]initWithTitle:@"Enter your Email-id" message:@"\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",nil];
emailTextField=[[UITextField alloc]initWithFrame:CGRectMake(12,45,260,25)];
[emailTextField becomeFirstResponder];
[emailTextField setBackgroundColor:[UIColor whiteColor]];
emailTextField.clearButtonMode=UITextFieldViewModeWhileEditing;
emailTextField.placeHolder=@"Email";
[emailAlert addSubview:emailTextField];
[emailAlert show];
[emailAlert release];
当点击OK按钮时,请使用UIAlertView委托方法。
