Be positive in thoughts and actions, world will be yours :)

How to Be Positive in Thoughts and Actions

By Alok yadav

Do you sometimes wonder how to be positive in your thoughts and actions, especially when you are unhappy and unsatisfied, or when life is difficult and tough? For many, it is difficult to be positive, even when things go well.

Though it's so simple, most people don't know how to be positive. Sometimes, they prefer to stay negative, because it is a more familiar state of mind.

Like every other subject, the know-how of how to be positive can be learned and the skill developed. It has much to do with changing your attitude and your mindset.

If you keep thinking the same thoughts, day and night, they might, sooner or later, manifest in your world, becoming your reality. This means that if you want your life to be as you want it to be, you have to be careful of what you think. You need to start thinking more positively.

Your Mind Creates Your Reality

As you think, so your life becomes. Changing your attitude and expectations, will sooner or later, change your life accordingly.

It is your mind that creates the kind of life you live. If you think positively, you will transform your life accordingly. Everything starts from within, from the most simple action, to the greatest achievement.

We cannot always control our external circumstances, but we can control our inner world of thoughts, where everything begins. We cannot always control our outer universe, but we can, with some effort, control our inner universe.

If you are unhappy and negative, you can change the way you feel and think.

With a little work and effort, you can change your attitude, expectations, actions and reactions, and this will lead to more motivation, happiness, and improved life conditions.

How to Be Positive

1. Substitute your negative thoughts with positive ones. Substitute thoughts about poverty, with thoughts about wealth, weakness with strength, lack of self esteem with self esteem, disharmony with harmony. Whenever you catch yourself thinking negatively, fill your mind with opposite thoughts, of happiness and success.
2. Focus on what you want, not on what you don't want.
3. Focus your mind on the good things you already have in your life. This will cause them to increase in your life.
4. Do not fill your mind with thoughts of lack. Think and believe that you already have abundance, success, love and happiness.
5. Learn to feel, think and even act, as if you are already living the life you want. If you can feel, think and act consistently in this way, you will become happier, and will attract new opportunities into your life.
6. Think about what you want, create a picture of it in your mind, and make it very clear and precise. Hold it there and focus on it in a positive way, until it becomes a reality in your life.
7. Always tell yourself, "I can", "I am able", "I can do it".
8. Often, during the day, repeat positive affirmations about what you want. Do so with faith, feelings, intention and focus.
9. Look for the good in every situation. There is always something good, or at least something useful to learn, even in difficult or unpleasant situations.
10. Follow your positive thoughts with positive actions. It is not enough to think, you also need to act to make things happen.
11. Always focus your mind on the full half of the cup, not on the empty half.
12. Be aware of your company. Choose to be around positive people.
13. Read about other people's success. Read things that inspire you and make you feel good.
14. Focus your mind on how to be positive and you will discover more ways to be so.

We get what we expect to get. Therefore, begin right now to expect the very best of everything that this world has to offer, and wish the same for everyone else. There is plenty of everything in the Universe for everyone, and the Universe can create more of the good things for everyone.

Don't think lack, think abundance, for you and for everyone else.

iOS – File Sharing Using WiFi

Objective: The main objective of this post is to describe how to share file between two apple devices using WiFi. In following demo I have described how to connect two devices using WiFi and then share large size image file by dividing it in data chunks and save shared file in camera roll of other device.

Note : To connect devices and share file application must be installed in both devices.
* Turn Off bluetooth while WiFi sharing, as it will interfere WiFi.

• 

Step 1: Create new XCode project name it as FileShareDemo. It contains one UIViewController Main.storyboard file.

Step 2: Add two UIButton in UIVIewController and set title “Connect” and “Share” respectively in both UIButton.

Step 3: Add MultipeerConnectivity framework in your project. Also add .png file which you want to share.

Step 4: In ViewController.h file you have to import MultipeerConnectivity framework, set delegate and declare property as below.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#import <UIKit/UIKit.h> #import <MultipeerConnectivity/MultipeerConnectivity.h>   @interface ViewController : UIViewController <MCBrowserViewControllerDelegate, MCSessionDelegate> { __block BOOL _isSendData; NSMutableArray *marrFileData, *marrReceiveData; int noOfdata, noOfDataSend; }   @property (nonatomic, strong) MCBrowserViewController *browserVC; @property (nonatomic, strong) MCAdvertiserAssistant *advertiser; @property (nonatomic, strong) MCSession *mySession; @property (nonatomic, strong) MCPeerID *myPeerID;   @end

Step 5: Initialize both NSMutableArray object in viewDidLoad method.

1 2 3 4 5 6

- (void)viewDidLoad { [super viewDidLoad]; marrFileData = [[NSMutableArray alloc] init]; marrReceiveData = [[NSMutableArray alloc] init]; }

Step 6: Initialize MCSession object, MCBrowserViewController object, and MCPeerID object in setUpMultipeer method.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

-(void)setUpMultipeer { // Setup peer ID self.myPeerID = [[MCPeerID alloc] initWithDisplayName:[UIDevice currentDevice].name];   // Setup session self.mySession = [[MCSession alloc] initWithPeer:self.myPeerID]; self.mySession.delegate = self;   // Setup BrowserViewController self.browserVC = [[MCBrowserViewController alloc] initWithServiceType:@"chat" session:self.mySession]; self.browserVC.delegate = self;   // Setup Advertiser self.advertiser = [[MCAdvertiserAssistant alloc] initWithServiceType:@"chat" discoveryInfo:nil session:self.mySession]; [self.advertiser start]; }

Also implement below methods in your ViewController.m file.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

-(void)showBrowserVC { [self presentViewController:self.browserVC animated:YES completion:nil]; }   -(void)dismissBrowserVC { [self.browserVC dismissViewControllerAnimated:YES completion:nil]; }   -(void)stopWifiSharing:(BOOL)isClear { if(isClear && self.mySession != nil){ [self.mySession disconnect];   [self.mySession setDelegate:nil];   self.mySession = nil;   self.browserVC = nil; } }

Step 6: Call setUpMultipeer and showBrowserVC methods from connect button action method.

1 2 3 4 5 6 7

-(IBAction)btnConnectClicked:(id)sender { if (!self.mySession) { [self setUpMultipeer]; } [self showBrowserVC]; }

Step 7: Implement MCBrowserViewControllerDelegate methods.

1 2 3 4 5 6 7 8 9 10 11 12 13

#pragma marks MCBrowserViewControllerDelegate // Notifies the delegate, when the user taps the done button -(void)browserViewControllerDidFinish:(MCBrowserViewController *)browserViewController { [self dismissBrowserVC]; [marrReceiveData removeAllObjects]; }   // Notifies delegate that the user taps the cancel button. -(void)browserViewControllerWasCancelled:(MCBrowserViewController *)browserViewController { [self dismissBrowserVC]; }

Step 7: Now in sendData method divide your image in data chunks and call sendData:toPeers:withMode :error method of MCSession object and pass data chunk in it to connected peer.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

-(void)sendData { [marrFileData removeAllObjects];   NSData *sendData = UIImagePNGRepresentation([UIImage imageNamed:@"test2.PNG"]); NSUInteger length = [sendData length]; NSUInteger chunkSize = 100 * 1024; NSUInteger offset = 0; do { NSUInteger thisChunkSize = length - offset > chunkSize ? chunkSize : length - offset; NSData* chunk = [NSData dataWithBytesNoCopy:(char *)[sendData bytes] + offset length:thisChunkSize freeWhenDone:NO]; NSLog(@"chunk length : %lu",(unsigned long)chunk.length);   [marrFileData addObject:[NSData dataWithData:chunk]]; offset += thisChunkSize; // do something with chunk } while (offset < length);   noOfdata = [marrFileData count]; noOfDataSend = 0;   if ([marrFileData count] > 0) { [self.mySession sendData:[marrFileData objectAtIndex:noOfDataSend] toPeers:[self.mySession connectedPeers] withMode:MCSessionSendDataReliable error:nil]; } }

Step 9: Call sendData method from send button action method.

1 2 3 4

- (IBAction)btnSendClicked:(id)sender { [self sendData]; }

Step 8: Add appendFileData method to append all chunks and save file on receiver device and display alert message after image saved successfully in camera roll.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

-(void)appendFileData { NSMutableData *fileData = [NSMutableData data];   for (int i = 0; i < [marrReceiveData count]; i++) { [fileData appendData:[marrReceiveData objectAtIndex:i]]; }   [fileData writeToFile:[NSString stringWithFormat:@"%@/Image.png", [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]] atomically:YES];   UIImageWriteToSavedPhotosAlbum([UIImage imageWithData:fileData], self, @selector(image:didFinishSavingWithError:contextInfo:), nil); }   - (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { if (!error) { [self invokeAlertMethod:@"Successfully Sent" Body:@"Image shared successfully and saved in Cameraroll." Delegate:nil]; } }   - (void)invokeAlertMethod:(NSString *)strTitle Body:(NSString *)strBody Delegate:(id)delegate { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strBody delegate:delegate cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; alert = nil; }

Step 9: Add MCSessionDelegate methods.

#pragma marks MCSessionDelegate - (void)session:(MCSession *)session didReceiveData:(NSData *)data fromPeer:(MCPeerID *)peerID { NSLog(@"data receiveddddd : %lu",(unsigned long)data.length);   if (data.length > 0) { if (data.length < 2) { noOfDataSend++; NSLog(@"noofdatasend : %d",noOfDataSend); NSLog(@"array count : %d",marrFileData.count); if (noOfDataSend < ([marrFileData count])) { [self.mySession sendData:[marrFileData objectAtIndex:noOfDataSend] toPeers:[self.mySession connectedPeers] withMode:MCSessionSendDataReliable error:nil]; }else { [self.mySession sendData:[@"File Transfer Done" dataUsingEncoding:NSUTF8StringEncoding] toPeers:[self.mySession connectedPeers] withMode:MCSessionSendDataReliable error:nil]; } } else { if ([[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] isEqualToString:@"File Transfer Done"]) { [self appendFileData]; }else { [self.mySession sendData:[@"1" dataUsingEncoding:NSUTF8StringEncoding] toPeers:[self.mySession connectedPeers] withMode:MCSessionSendDataReliable error:nil]; [marrReceiveData addObject:data]; } } } }   - (void)session:(MCSession *)session didReceiveStream:(NSInputStream *)stream withName:(NSString *)streamName fromPeer:(MCPeerID *)peerID { NSLog(@"did receive stream"); }   - (void)session:(MCSession *)session didStartReceivingResourceWithName:(NSString *)resourceName fromPeer:(MCPeerID *)peerID withProgress:(NSProgress *)progress { NSLog(@"start receiving"); }   - (void)session:(MCSession *)session didFinishReceivingResourceWithName:(NSString *)resourceName fromPeer:(MCPeerID *)peerID atURL:(NSURL *)localURL withError:(NSError *)error { NSLog(@"finish receiving resource"); }   -(void)session:(MCSession *)session peer:(MCPeerID *)peerID didChangeState:(MCSessionState)state { NSLog(@"change state : %d",state); }
