Pods are generally used for dependency management in your XCode Project. Follow below mentioned steps to install pod easily : Step -1 Open your terminal. Step -2 Then Change the directory in terminal to the location of your xcode project. Step -3 When you reach to the desired project location first we need to create podfile using command “touch Podfile”. This will create a blank podfile in your project directory named “Podfile” Step -4 To open created Podfile enter command - “open -e Podfile” This will open your Podfile to text editor Step -5 Now you can enter pod name in file and save file. Some example are shown below pod ‘AFNetworking’, ’0.9.1′ pod ’Facebook-iOS-SDK’ pod ’EGOTableViewPullRefresh’ pod ’JSONKit’ pod ‘MBProgressHUD’ pod ’Reachability’ Step -6 To install pods in file enter command - “pod install” This will take some time to install pod Step -7 The extension of our Xcode project integrated with podfile is “YourProjec...

Most of the mobile applications use the email for login or other purpose. So we need to validate email if it contains the valid email string. We can achieve it by using NSPredicate. 1. Add following method 1. -(BOOL)isValidEmail:(NSString *)checkString 2. { 3. long numberOfAtPieces = [[checkString componentsSeparatedByString:@"@"] count]; 4. 5. if (numberOfAtPieces > 2){ 6. return NO; 7. } 8. 9. BOOL stricterFilter = NO; 10. NSString *stricterFilterString = @"[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za- z]{2,4}"; 11. NSString *laxString = @".+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*"; 12. NSString *emailRegex = stricterFilter ? stricterFilterString : laxString; 13. NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex]; 14. return [emailTest evaluateWithObject:checkString]; 15. } 2. Call this method and pass string containing email to it like below BOOL isValid =...

In iOS most of time we need to pass our data to the different parts of the code in same or another class. One of the easiest way to pass data is using local notification. Follow the below steps to implement Local Notification in your app 1. First we have to setup class observer for notification NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter]; 1. [notificationCenter addObserver:self selector:@selector(yourMethodName:) name:@"yourNotificationName" object:nil]; 2. Post Notification like below 1. NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter]; 2. [notificationCenter postNotificationName:@"yourNotificationName" object:yourObject]; 3.Get passed object using the following line of code 1. -(void)yourMethodName::(NSNotification *)notification{ 2. id passedObject = notification.object; 3. } 4. Remove observer while unloading or dealloc 1. [[NSNotificationCenter defaultCenter] rem...

Delegate is used for send receive data between two viewcontroller. For example if We have two View controllers namely FirstViewController and SecondViewController Step :1 Add the following line of code to FirstViewController.h file #import &lt;UIKit/UIKit.h&gt; @protocol MyDelegate -(void)MyDelegateMethod:(NSString *)description; @end @interface FirstViewController : UIViewController { } @property (nonatomic, weak) id MyDelegate; Step 2 : To implement the above created delegate method one needs to add the below mentioned code in SecondViewController.m file @interface SecondViewController()&lt;MyDelegate&gt; @end @implementation SecondViewController -(void)GoToFirst { FirstViewController *first = [[FirstViewController alloc]initWithNibName:@&quot;FirstViewController&quot; bundle:Nil]; first.MyDelegate = self; [self.navigationController pushViewController:cart animated:YES]; } // Delegate Method Goes Here -(void...

In iOS 8 and above UIAlertView is deprecated so you can’t use UIAlertView in your beloved application. Apple has recently introduced new UIAlertController instead of UIAlertView.
