iPhone

Well it been a while since I wrote something. Things has changed the main focus is iPhone. I'm going to some easy tutorial of things I hard time with.
Let's begin with some basic UI elements:

UITextField
Code:
UITextField *username =[[UITextField alloc] initWithFrame:CGRectMake(24.5, 65, 270, 30)];
username.delegate=self;
username.textAlignment=UITextAlignmentCenter;
username.borderStyle=UITextBorderStyleRoundedRect;
username.placeholder=@"Username\n";
username.autocorrectionType=UITextAutocorrectionTypeNo;
username.autocapitalizationType=UITextAutocapitalizationTypeNone;
[self.view addSubview:username];

UIActionSheet
Code:
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"This is where the information will go"
delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil
otherButtonTitles:@"Email", @"Tech Support",@"Website",@"Cancel", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
actionSheet.destructiveButtonIndex = 3; // make the second button red (destructive)
[actionSheet showInView:self.view];
[actionSheet release];
Selecting a button on UIActionSheet
Code:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
// do stuff
}
}

UISwitch
Code:
UISwitch *switchIt = [[UISwitch alloc] initWithFrame:CGRectZero];
switchIt.on=NO;
[self.contentView addSubview:switchIt];
UILabel
Code:
UILabel *usernameLabel = [[UILabel alloc] initWithFrame:CGRectZero];
usernameLabel.text=@"Personal Location Checkin";
usernameLabel.adjustsFontSizeToFitWidth=YES;
[self.contentView addSubview:usernameLabel];
UISearchBar
Code:
UISearchBar *mySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];
mySearchBar.delegate = self;
mySearchBar.showsCancelButton = YES;
mySearchBar.barStyle=UIBarStyleBlackOpaque;
mySearchBar.placeholder=@"Enter Name or Phone Number";
mySearchBar.keyboardType=UIKeyboardTypeNamePhonePad;


[self.view addSubview: mySearchBar];
UIView
Code:
UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
contentView.backgroundColor = [UIColor grayColor];
self.view = contentView;
[contentView release];
UITableView
Code:
UITableView *myBeaconsTableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 45, self.view.bounds.size.width, 375)];
myBeaconsTableView.delegate=self;
myBeaconsTableView.dataSource=self;

[self.view addSubview:myBeaconsTableView];
Or to make a grouped table view (like in preferences)

Code:
UITableView *settingsTableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 40, self.view.bounds.size.width, 375) style:UITableViewStyleGrouped];
settingsTableView.delegate=self;
settingsTableView.dataSource=self;
[self.view addSubview:settingsTableView];
UINavigationBar
Plain no Title
Code:
myNavBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];
[self.view addSubview:myNavBar];
Black Opaque (no title)
Code:
myNavBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];
myNavBar.barStyle=UIBarStyleBlackOpaque;
[self.view addSubview:myNavBar];
Black Translucent (no title)
Code:
myNavBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];
myNavBar.barStyle=UIBarStyleBlackTranslucent;
[self.view addSubview:myNavBar];
To add title and other buttons

Code:
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:@"Around Me"];
[myNavBar pushNavigationItem: navItem];
To add buttons with image
Code:
refreshButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(action:)];
[navItem setLeftBarButtonItem:refreshButton];
Add button with Text
Code:
refreshButton = [[UIBarButtonItem alloc] initWithTitle:@"About Us" style:UIBarButtonItemStyleBordered target:self action:@selector(action:)];
[navItem setRightBarButtonItem:refreshButton];
How to add comments
Code:
When you want to add a comment about a line of code you do this

// Comment

To do a multi-lined comment you would do this

/* This
is
multi-lined
comment
*/
UIWebView
Code:
dailyWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0.0, 45, self.view.bounds.size.width, 375)];
dailyWebView.delegate=self;
dailyWebView.scalesPageToFit=YES;
[dailyWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]]];
[self.view addSubview:dailyWebView];
UITextView
Code:
UITextView *textView = [[[UITextView alloc] initWithFrame:frame] autorelease];
textView.textColor = [UIColor blackColor];
textView.font = [UIFont fontWithName:@"Helvetica" size:15];
textView.delegate = self;
textView.backgroundColor = [UIColor whiteColor];

textView.text = @"TEXT TO GO IN HERE";
[self.view addSubView:textView];

UISegmentedControl
Code:
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
[UIImage imageNamed:@"segment_check.png"],
[UIImage imageNamed:@"segment_search.png"],
[UIImage imageNamed:@"segment_tools.png"],
nil]];
frame = CGRectMake( 0,
0,
self.view.bounds.size.width,
35);
segmentedControl.frame = frame;
[segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
segmentedControl.selectedSegmentIndex = 1;
[self.view addSubview:segmentedControl];
UIAlertView
Code:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" message:@"Your message"
delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Button1", @"Button2", nil];
[alert show];
[alert release];

This is just some UI elements that can be added through code
