How to Disable Application Transport Security

You just have to add NSAllowsArbitraryLoads boolean YES in

NSAppTransportSecurity dictionary

How to use Protocol Delegate in iOS using Swift language

Define Protocol

There are two controllers:
FirstViewController
SecondViewController

I need to notify FirstViewController that SecondViewController ViewDidAppearCalled

import UIKit

//Define Your protocole here after Import

protocol SecondViewControllerDelegate{

      

    //Add a new function

    func SecondViewDidLoadFinished(controller:SecondViewController)

}

class SecondViewController: UIViewController {

   

    

    var delegate:SecondViewControllerDelegate?

    override func viewDidLoad() {

        super.viewDidLoad()

    }

override func viewDidAppear(animated: Bool) {

        

        if let delegate = self.delegate{

            delegate.SecondViewDidLoadFinished(self)

        }

    }

First view

import UIKit

class FirstViewController: UIViewController,SecondViewControllerDelegate {

    

    override func viewDidLoad() {

        super.viewDidLoad()

    }

@IBAction func buttonTapped(sender:UIButton){

        

        let mapObject:SecondViewController = SecondViewController()

        mapObject.delegate = self

        self.navigationController?.pushViewController(mapObject, animated: true)   

    }

func SecondViewDidLoadFinished(controller: SecondViewController) {

//Here you will be notified that second view viewDid appear loaded

        

    }

iOS 9 issue: The app could not be loaded because the app transport security policy requires the use of secure connection.

I have solved it with adding some key in info.plist. The steps I followed are:

Opened my Projects info.plist file

Added a Key called NSAppTransportSecurity as a Dictionary.

Added a Subkey called NSAllowsArbitraryLoads as Boolean and set its value to YES as like following image.

iOS Generate Random string

+(NSString *) generateRandomString

{

    NSString *letters = @"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

    int len = 8;

    NSMutableString *randomString = [NSMutableString stringWithCapacity: len];

    

    for (int i=0; i<len; i++) {

        [randomString appendFormat: @"%C", [letters characterAtIndex: arc4random_uniform([letters length])]];

    }

    

    return randomString;

}

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];
