Question

我有四个Uitextfields，在一个文本字段中我设置了操作表和三个ohthers只是用于文本输入。这是我的代码..

   - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{    

    if(textField.tag==3)// tag will be integer
    {    
        NSLog(@"ACTION SHEET WILL DISPLAY");    
        [textField setUserInteractionEnabled:YES]; 
        [textField resignFirstResponder];            
        UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:nil otherButtonTitles:@"Manpower", @"Admin",@"Research" ,nil];
        actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
        [actionSheet showInView:self.view]; 
    }

    return YES;

}


-(BOOL)textFieldShouldReturn:(UITextField*)textField {

    if (textField.tag) {            
        UIResponder *nextField = [textField viewWithTag:(textField.tag + 1)];            
        [nextField becomeFirstResponder];            
    }

    else {            
        // Unknown field, just resign first responder.            
        [textField resignFirstResponder];            
    }

    return NO;       
}

现在我的问题是当我从三个文本字段中的任何一个按下键盘TAB键时，我的操作表显示出来了！虽然如果我单独单击文本字段，它可以正常工作。

你所做的只是给xib中的不同文本域提供不同的标签，然后比较文本字段名称只比较标签并为该文本字段返回NO，这样当动作表打开时，键盘不会弹出...

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{    

 if(textField.tag==your textfield tag)// tag will be integer
 {    
  NSLog(@"ACTION SHEET WILL DISPLAY");    
    [textField setUserInteractionEnabled:YES]; 
    [textField resignFirstResponder];            
        UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:nil otherButtonTitles:@"Manpower", @"Admin",@"Research" ,nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view]; 
return NO;         
} 
 else
{
  return YES;
}

 }

让我知道它的工作与否......

快乐编码...... !!!!!

可能会帮助你

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{    

    if(textField == dept_label)
 {    
   NSLog(@"ACTION SHEET WILL DISPLAY");    
    [textField setUserInteractionEnabled:YES]; 
    [textField resignFirstResponder];            
        UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:nil otherButtonTitles:@"Manpower", @"Admin",@"Research" ,nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view];         

 return NO;
} 


else
{
return YES;
}       
}
