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)]; 
}

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);
}
}
