UIWindow *keyboardWindow = nil;

- (void)removeBar {

                if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {

                    for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {

                        NSRange range = [[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"];

                        if (range.location != NSNotFound) {

                            [subviewWhichIsPossibleFormView removeFromSuperview];

Add Views to UIAlertView

1. Create UIAlertView with buttons using UIAlertView initWithTitle methods with buttons.
2. create the views wich you wish and add it to AlertView using addSubView: methods.
3. use below delegate method to organize your views.
     - (void)willPresentAlertView:(UIAlertView *)alertView

// create alertView

-(void)configureAlert{

     alertView = [[UIAlertView alloc] initWithTitle:@"Tittle" message:@"message" delegate:self                                    

cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok",nil];

     textField = [[UITextField alloc] initWithFrame:CGRectMake(12, 86, 262, 28)];

     [textField becomeFirstResponder];
     [textField setPlaceholder:@"Password"];
     [textField setReturnKeyType:UIReturnKeyDone];  

     [textField setInputAccessoryView:customAccView1];
     [textField setFont:[UIFont fontWithName:@"Helvetica Neue" size:18]];
     [textField setContentMode:UIViewContentModeBottom];
     [textField setBackgroundColor:[UIColor whiteColor]];

     // vertical alignment of text in textField

     [textField setContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];
     [alertView textField];
     [alertView show];
}

- (void)willPresentAlertView:(UIAlertView *)alertView { 

          [alertView setFrame:CGRectMake(17, 30, 286, 188)];

          NSArray *subviewArray = [alertView subviews];

          UILabel *label = (UILabel *)[subviewArray objectAtIndex:2];

          [label setFrame:CGRectMake(10, 46, 260, 20)];

          UIButton *buttonOk = (UIButton *)[subviewArray objectAtIndex:4];

          [buttonOk setFrame:CGRectMake(10, 130, 128, 42)];

           UIButton *buttonCancel = (UIButton *)[subviewArray objectAtIndex:3];

          [buttonCancel setFrame:CGRectMake(148, 130, 128, 42)]; 

}

   
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
     // button actions
}

Transparent UIWebView

To transparent the UIWebView and remove the scrolls.

webView.opaque = NO;
webView.backgroundColor = [UIColor clearColor];
for(UIView *view in webView.subviews){ 

     if ([view isKindOfClass:[UIImageView class]]) {

          // to transparent 

          [view removeFromSuperview];

     }
     if ([view isKindOfClass:[UIScrollView class]]) {
          UIScrollView *sView = (UIScrollView *)view;

          //to hide verticalScroller

          sView.showsVerticalScrollIndicator = NO;

          for (UIView* shadowView in [sView subviews]){

               //to remove shadow

               if ([shadowView isKindOfClass:[UIImageView class]]) {

                    [shadowView setHidden:YES];

               }

          }

     }
}

iPhone application lifecycle

Here is an interesting article about iPhone's application lifecycle that I came across.

http://www.codeproject.com/KB/iPhone/ApplicationLifeCycle.aspx

Export and import contacts to iPhone contacts database

Export....

ABAddressBookRef addressBook = ABAddressBookCreate();

ABRecordRef person = ABPersonCreate();

CFErrorRef anError = NULL;

ABRecordSetValue(person, kABPersonFirstNameProperty, @"Don Juan", NULL);

ABAddressBookAddRecord (addressBook,person,nil);

ABAddressBookSave(addressBook, &anError);

Import....

ABAddressBookRef addressBook = ABAddressBookCreate();

int noOfPerson = ABAddressBookGetPersonCount(addressBook);

NSMutableArray *allPeople = (NSMutableArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

for(int i=0; i < noOfPerson; i++ ){

ABRecordRef person = [allPeople objectAtIndex:i];

if(ABRecordCopyValue(person, kABPersonEmailProperty) != NULL){  // Checks if email for the contact exists

}

NSString *firstName;

if(ABRecordCopyValue(person, kABPersonFirstNameProperty) != NULL){

firstName = [[NSString stringWithFormat:@"%@", ABRecordCopyValue(person, kABPersonFirstNameProperty)] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

NSLog(@"%@",firstName);

}

NSString *lastName;

if(ABRecordCopyValue(person, kABPersonLastNameProperty) != NULL){

lastName = [[NSString stringWithFormat:@"%@", ABRecordCopyValue(person, kABPersonLastNameProperty)] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

NSLog(@"---%@ ",lastName);

}

}
