SQLite DB Integration in iOS -- Basic Tutorial ,(In Process ....)

This Post is in under Development, it will be final soon....................

This post is the basic SQLite integration in iOS project for newcomers, if you are experienced developer then it will not be helpful for you :

To create database and manage tables you can add SQLite Manager Add-Ons in Firefox please follow the below guideline:

SQLite Manager Firfox Add-ons

Open SQLite Manager from Firefox:

Creating new Database:

Creating a Table :

Optional:

For SQLite DB this tool is also very helpful, if you wish to use just open sqlite file with Navicate:

Navicat Sqlite Manager

Drag your SQLite database file into your project:

Make sure create group for any added folder is selected and add to target your project as show in belowimage.

Copy Database into Document Directory:

You can call this method in didFinishLaunchingWithOptions in Appdelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

// Override point for customization after application launch.

//Copy Database into Document Directory

[self copyDB];

}

-(void)copyDB

{

//sample is the name of your database

NSString *str = [[NSBundle mainBundle]pathForResource:@"sample" ofType:@"sqlite"];

NSString *docpath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

NSString *destPaht = [docpath stringByAppendingPathComponent:@"sample.sqlite"];

NSLog(@"databse path %@",destPaht);

NSFileManager *mgr = [NSFileManager defaultManager];

if (![mgr fileExistsAtPath:destPaht])

{

[mgr copyItemAtPath:str toPath:destPaht error:nil];

}

//Below is class method for Select Query to get all records from table:

+(NSMutableArray *)GetAllRecords

{

NSMutableArray *finalempArr =[NSMutableArray array];

sqlite3 *database;

if (sqlite3_open([Database_Path UTF8String], &database) == SQLITE_OK)

{

NSString *selectSql;

selectSql = [NSString stringWithFormat:@"SELECT * FROM records"];

sqlite3_stmt *statement;

if (sqlite3_prepare_v2(database, [selectSql cStringUsingEncoding:NSUTF8StringEncoding], -1, &statement, NULL) == SQLITE_OK)

{

while (sqlite3_step(statement) == SQLITE_ROW)

{

NSMutableDictionary *empDic =[NSMutableDictionary dictionary];

//here we get all column entries from table

NSString *emp_id = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement,0)];

NSString *emp_name = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement,1)];

NSString *emp_age = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement,2)];

NSString *emp_address = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement,3)];

NSString *emp_cell = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement,4)];

//adding entries in dictionary optioanl

[empDic setValue:emp_id forKey:@"id"];

[empDic setValue:emp_name forKey:@"name"];

[empDic setValue:emp_age forKey:@"age"];

[empDic setValue:emp_address forKey:@"address"];

[empDic setValue:emp_cell forKey:@"cell"];

[finalempArr addObject:empDic];

empDic=nil;

}

sqlite3_finalize(statement);

}

else

{

NSLog(@"Error");

}

sqlite3_close(database);

database=nil;

}

else

{

NSLog(@"Database cant open");

}

return finalempArr;

}

You can call above method like this:

[DatabaseClass GetAllRecords];

You can download Sample SQLite Integration Code from here.

UIKeyboard notifications Show & Hide - iPhone SDK

This post will help you integrate keyboard Notifications to handle the show and hide functionality

Below are two observer which keep listening keyboard actions . You can keep this two observer in viewdidload

OBSERVERS:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardDidShowNotification object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardDidHideNotification object:nil];

These are two delegate methods and these will be trigered on keyboard actions.

DELEGATE METHODS:

- (void)keyboardWillShow:(NSNotification*)notification

{

}

SIMPLE PROTOCOL & DELEGATE EXAMPLE

PROTOCOL & DELEGATE

two controllers

FirstViewController

SecondViewController

SecondViewController.h

@protocol SecondViewControllerDelegate;

@property (nonatomic, weak) id<SecondViewControllerDelegate> delegate;

@protocol SecondViewControllerDelegate <NSObject>

- (void)SecondViewController:(SecondViewController*)viewController

didChooseValue:(CGFloat)value;

SecondViewController.m

-(IBAction)SecondTap:(id)sender

{

id<SecondViewControllerDelegate> strongDelegate = self.delegate;

// Our delegate method is optional, so we should

// check that the delegate implements it

if ([strongDelegate respondsToSelector:@selector(SecondViewController:didChooseValue:)]) {

[strongDelegate SecondViewController:self didChooseValue:[sender tag]];

}

FirstViewController.h

@interface FirstViewController : UIViewController<SecondViewControllerDelegate>

FirstViewController.m

-(IBAction)Add:(id)sender

{

SecondViewController *objsecond =[[SecondViewController alloc]init];

[objsecond setDelegate:self];

[self.view addSubview:objsecond.view];

}

- (void)SecondViewController:(SecondViewController *)viewController didChooseValue:(CGFloat)value

{

// Do something with value...

// ...then dismiss the child view controller

[viewController.view removeFromSuperview];

}

Generate PEM certificate from P12 certificate

Open terminal and go to the path where you place p12 certificate and run this complete below command:

openssl pkcs12 -in certificateName.p12 -out certificateName.pem -nodes

iOS Timer Counter !!

Here is the Timer counter simple example in which we will get seconds, minutes, and hours

Call the below method TimerCounter:

int secondsSpent;

NSTimer *timer= [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(TimeCounter) userInfo:nil repeats:YES];

- (void)TimeCounter

{

    secondsSpent ++ ;

    hours = secondsSpent / 3600;

    minutes = (secondsSpent % 3600) / 60;

    seconds = (secondsSpent %3600) % 60;

    NSLog(@"Time spent: %02d:%02d:%02d", hours, minutes, seconds);

}

iOS Local Notifications

Here we have sample code for local notification

    UILocalNotification *notification = [[UILocalNotification alloc] init];

    notification.alertBody =@"Test Message";

    notification.soundName = UILocalNotificationDefaultSoundName;

    [[UIApplication sharedApplication] presentLocalNotificationNow:notification];

How null,nill, and lenght 0 object can be checked ???

The simplest way to check NSNull value , nill value, and lenght =0 of object:

static inline BOOL IsEmpty(id object)

{

    return object == nil

    || ([object respondsToSelector:@selector(length)]

        && [(NSData *) object length] == 0)

    || ([object respondsToSelector:@selector(count)]

        && [(NSArray *) object count] == 0)

    || ([object respondsToSelector:@selector(count)]

        && object == nil)

    || ([object respondsToSelector:@selector(count)]

        && [ object isKindOfClass:[NSNull class]]);

}

How to call inline function:

 NSString *str =nil;

    if(!(IsEmpty(str)))

{

        NSLog(@"The object is not null, nill,");

}
