- Content Providers: Supplies data from one application to others on request. A Content Provider can use different ways to store its data and the data can be stored in a database, in files, or even over a network.
Content URI: To query a content provider, you specify the query string in the form of a URI which has the following format
Prefix + Authority + data_type + ID
Create a Content Provider:
CONTENT PROVIDER
--- > Fragments
A Fragment is a piece of an activity which enable more modular activity design. It will not be wrong if we say, a fragment is a kind of sub-activity.
Following are important points about fragment −
-
A fragment has its own layout and its own behaviour with its own life cycle callbacks.
-
You can add or remove fragments in an activity while the activity is running.
-
You can combine multiple fragments in a single activity to build a multi-pane UI.
-
A fragment can be used in multiple activities.
-
Fragment life cycle is closely related to the life cycle of its host activity which means when the activity is paused, all the fragments available in the activity will also be stopped.
-
A fragment can implement a behaviour that has no user interface component.
-
Fragments were added to the Android API in Honeycomb version of Android which API version 11.

IOS Apps Development History?
- Mobile Operating System Developed by Apple Inc + First release 2017 + Including iPad and iPhone Touch. iPad first release 2010
Registering as an Apple Developer Account?
- Create Account & Fill the Account Register Form?
Xcode Installation & Interface Builder + Simulator?
- Interface & Implementation: these are very important to declare class
- Object Create OB: MyClass * ObjectName = [[MyClass allocint];
- Methods Creation OB: -(void)MethodName
- Class Methods - Accessed without any objects, Variables, etc.
- Instance Methods: Can be accessed only after creating an object for a class. Memory Allocated to Instance Variable. -(void)InstanceMethod
Important Data Type of Objective-C
- NSString + CGFloat + NSInteger + Bool
- Accessing Properties represents from dot ex self.myString =@"test";
- Array ----> NSMutableArray & NSArray Difference Static & Dynamic
- Dictionary -----> NSMutableDictionary & NSDictionary
- Node. JS for IOS & JavaScript + How to Upload Images or files to Node. JS + Creating Restful API with Node. JS + AFNetworking
IOS App Important Files
1. AppDelegate.h ----> Inherits from UIResponder that handle IOS Events
2. AppDelegate.m ----> No User-defined methods
3. ViewController.h ----> Provide Fundamental View Management or Interface
4. VIewController.m ----> Base class and implement Coding ----> ViewDidLoad

Q1: Interview Question: How do you Manage Memory in Objective-C?
Answer: Memory Allocation in Objective-C is done dynamically. Memory is Allocated during the runtime of any Program. For Allocating Memory in Objective-C, there are two ways.
1. Manual Retain Release (MRR): In this type of memory management, memory is explicitly managed and all objects have kept a track of. It uses the reference counting model for keeping this track.
2 Automatic Reference Counting (ARC): Here they system capable of inserting an appropriate memory management method calls which are called the runtime.
Q2: What is Declared properties in Objective C?
Answer: Any Property which is to be used by declaring different instance variables by implementing the getter and setter methods which help to enforce encapsulation. There are three aspects to properties, Include the declaration, implementation, and access. Properties declared in any class, category and protocols.
- @propety(attributes......) type propertyname
- It also has attributes which are optional. 1. Read-only: This property can only read and not written. 2. Read-Write: Enable reading and writing both. 3. Assign: Used in the implementation of any setter. 4. Retain: is sent to the property once it is assigned. 5. copy: retain this operation is also performed once the property is assigned.
- Strong Simple defines ownership of the Object + Deallocation of the Object + Strong we use Parent of the Object. Increase Reference Count.
- Retain is Use when we want to remove the previous value once new setter comes for the same object.
- Atomic: is property is default in case of thread safety but can be overridden with nonatomic. An atomic attribute defines that, the property is thread safe and will always return a true value. Probability of a garbage value is very least. Since its a thread-safe attribute so it takes a large time in execution than its competitor nonatomic.
- NonAtomic: NonAtomic property is not thread safe and doesn’t guarantee a true result but it will always give a result.
Q3: Is it possible to use ARC and Non-ARC doe together in a project?
Answer: Yes, a project can use both ARC and Non-ARC codes. When a project chooses Non-ARC codes then --fobj-arc compiler flag is set. This is ARC can be disabled for specific classes by using -fno-obc-arc.
This entire process can be done by Xcode → Project→ Build Phase→ Compile Sources→ Double Click on the class and set the –fno-objc-arc.
Q4: What are the methods of using NSUL Connect?
Answer: A connection which received the response + A Connection which receives data + A connection which did finish on loading
Q4: What is the protocol in Objective-C?
Answer: A Protocol is said to be a language feature which provides multiple inheritances in a language which has a single inheritance. Objective C mainly supports two protocols Formal Protocols are also known as Compiler Protocols and informal protocols also known as ad-hoc protocols.
Q5: What is atomic and non-atomic in Objective C and which one is considered to be a default?
Answer: This method is used to specify the accessor methods which are atomic. The process which is being currently run is completed by the CPU before any other process accesses the variable. Non-Atomic is for the variables which are non-atomic. These are faster but no thread safe.
Q6: Difference Between Storyboard & XIB
Q7: How to Create Attractive Interface Builder a Project?
Q8: What is MBProgressHUD & Cocoapods & cocoa touch? Library & Frameworks
Q9: Difference B/W Weak Outlet & Strong Outlet?
Q10: @Synthesize is the compiler will understand your property + Also generate getter and setter methods for your property.
Q11: What is the difference between Synchronous & Asynchronous Task?
Running Something on a Background Thread
- Answer: Synchronous waits until the task has completed Asynchronous: not waits
---> Key difference between synchronous and Synchronous, it implies that two things must occur at the same time, or alternatively, that one of them must wait until the other one catches up. Asynchronous, it means that the two things don't know or care when the other is happening.
Q12: What is made up of NSError Object?
- Answer: There are three parts of NSError object a domain, an error code, and user info dictionary. The domain is a string that identifies what categories of errors this error is coming from.
Q13: What is Enum or Enumerations?
- Answer: Managing state, Enumerations define a finite number of states and can bundle associated values with each individual state, you can use them to model the state of your app and its internal processes.
Enum is a type that basically contains a group of related values in the same umbrella but case-less enum won't allow us to create an instance.
Q13: What is @synthesize in Objective-C?
- Answer: Synthesize generates getter and setter methods for your property.
