Push-Notification Change in iOS8

in ios 8 so many things change in one of them one change is related to push notification.

If you run your old push notification code in Xcode 6 then it will give you warning also some methods deprecated in ios 8
registerForRemoteNotificationTypes is deprecated in ios 8 instead of it in ios 8 we use UIUserNotificationSettings like this way:

           #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
            if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
                UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
                [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
            } else {
                [[UIApplication sharedApplication]
                 registerForRemoteNotificationTypes:
                 (UIRemoteNotificationTypeAlert |
                  UIRemoteNotificationTypeBadge |
                  UIRemoteNotificationTypeSound)];
            }
        #else
            [[UIApplication sharedApplication]
             registerForRemoteNotificationTypes:
             (UIRemoteNotificationTypeAlert |
              UIRemoteNotificationTypeBadge |
           
 
     UIRemoteNotificationTypeSound)];
    #endif


and for delegate methods,



      #pragma mark - Push Notification
 
    - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
   
    // Prepare the Device Token for Registration (remove spaces and < >)
    NSString *TokenID = [[[[deviceToken description]
                               stringByReplacingOccurrencesOfString:@"<"withString:@""]
                              stringByReplacingOccurrencesOfString:@">" withString:@""]
                             stringByReplacingOccurrencesOfString: @" " withString: @""];
   
     
        [ApplicationPreferences setTokenId:TokenID];
    if (DEBUG_MODE) {
    NSLog(@"device token - %@",[NSString stringWithFormat:@"Device Token = %@",TokenID]);
            NSUUID *oNSUUID = [[UIDevice currentDevice] identifierForVendor];
            NSLog(@"Vendor token - %@",[NSString stringWithFormat:@"Device Token = %@",[oNSUUID UUIDString]]);
    }
 
    }
 
    - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
    {
        //register to receive notifications
        [application registerForRemoteNotifications];
    }
 
    - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
        if (DEBUG_MODE) {
    NSLog(@"Push Error- %@",[NSString stringWithFormat: @"Error: %@", err]);
        }
    }
    - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
     
    }

ios 8 changes for actionsheet

In ios 8 apple has changed so many things i here faced one problem in my own project so , i just want to provide the solution in replacement of UIActionsheet.

   in ios 8 UIActionSheet deprecated as well its delegate methods also deprecated. Instead of that UIAlertController with prefferedstyle 
UIAlertControllerStyleActionSheet  is used. you can check this thread as well:

https://developer.apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html

This example will work both in ios 8 and previous version of it.

in .h file declare this variable

@interface demoProfileForBuyer{

 UIActionSheet *ac_sheet_fordate;

    UIToolbar *pickerToolBar_fordate;

    UIDatePicker *optionPickerDate;

UIAlertController *alertController;

}

in .m file

I hope this will help, and this code will display the same action sheet kind of view as it displayed in ios 7 .

Predicates and compound predicate to filter data

Hi friends in normal iphone application in all applications we see search feature normally.
Search can be done from server side as well as from application side locally.

we can search data locally using NSPredicate and NSCompoundPredicate .

I have one NSMutableArray which i created this way:

NSMutableArray *arrAllData = [NSMutableArray array];

[arrAllData addObject :@{@"id":@"1",@"title":@"Mittal",@"search_type":@"Sr Enginner",}];

[arrAllData addObject :@{@"id":@"2",@"title":@"Rupal",@"search_type":@"Jr Enginner",}];

[arrAllData addObject :@{@"id":@"3",@"title":@"Sunny",@"search_type":@"QA",}];

[arrAllData addObject :@{@"id":@"3",@"title":@"Adithi",@"search_type":@"Director",}];

[arrAllData addObject :@{@"id":@"3",@"title":@"Nirman",@"search_type":@"Director",}];

Now we want to filter the data according to Boss and Employee:

Please apply this code.

NSMutableArray *predicates = [NSMutableArray array];

NSString *filter = @"search_type == %@";

NSPredicate *commonPred = [NSPredicate predicateWithFormat:filter, @"Sr Enginner"];

[predicates addObject:commonPred];

NSPredicate *jrEngineerPred = [NSPredicate predicateWithFormat:filter, @"Jr Enginner"];

[predicates addObject: jrEngineerPred];

NSPredicate *QAPred = [NSPredicate predicateWithFormat:filter, @"QA"];

[predicates addObject:QA];

NSPredicate *resultPredicate = [NSCompoundPredicate orPredicateWithSubpredicates:predicates];

NSArray *arr_Data = [arrAllData filteredArrayUsingPredicate:resultPredicate];

 NSMutableArray *arSearchEmployeeData = [arr_Data mutableCopy];

arr_Data =  [NSMutableArray alloc]init];

commonPred = [NSPredicate predicateWithFormat:filter, @"Director"];

arr_Data = [arrAllData filteredArrayUsingPredicate:

                              commonPred];

 NSMutableArray *arSearcBossData = [arr_Data mutableCopy];

Happy Coding!!

Thanks.

Attributed String With different Color and Italic

Hi  attributedString is introduced in ios 3.2 but However the ability to use them within certain UI controls such as UILabel, UIButton, UITextView, etc is only available since iOS6. I will discuss it here in this blog.

To give color attribute and italic effects in string you have to declare one  NSAttributedString like this :

#define MAINCOLOR [UIColor colorWithRed:51/255.0 green:51/255.0 blue:51/255.0 alpha:1.0]

NSMutableAttributedString * Subtitlestring ;

[Subtitlestring addAttribute:NSForegroundColorAttributeName value:MAINCOLOR range:NSMakeRange(0,[strMovieName length])]; 

[Subtitlestring addAttribute:NSFontAttributeName value:[[Util sharedUtil] fontOfType:

@"HelveticaNeue-Italic bold:NO size:12 range:NSMakeRange(0,[Subtitlestring length])];

[lblSubtitle setAttributedText:Subtitlestring];

This will display gray  color  and italic string in label. 

Cheers!!!!

Get Contacts from Address Book then compare them with database Data and check existance

One of the my project i have to display contacts from contact book and compare them from my database.

For that first you have to read data from the addressbook for that apply the code as below.

-(NSMutableArray*)getaddressBookArray{

    addressBook = nil;

    __block NSMutableArray *arrayOfPeople = nil;

    __block BOOL userDidGrantAddressBookAccess;

    CFErrorRef addressBookError = NULL;

    

    if ( ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined ||

        ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized )

    {

        addressBook = ABAddressBookCreateWithOptions(NULL, &addressBookError);

        

        dispatch_semaphore_t sema = dispatch_semaphore_create(0);

        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error){

            userDidGrantAddressBookAccess = granted;

            arrayOfPeople = [(__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook) mutableCopy];

            dispatch_semaphore_signal(sema);

        });

        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);

    }

    else

    {

        if ( ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusDenied ||

            ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusRestricted )

        {

            // Display an error.

        }

    }

    

    return arrayOfPeople;

    

}

Here three case may happen
1> First you have to check whether user has allowed access of contacts or not then array will be empty
2>  Either there are not any records in address book or not then if no contacts available then contacts array remain empty
3> If contacts found then check them from database which you stored internally like this way



In Database I have one table like contacts which has fields like firstName, lastName, number stored which came from sync api i get them in  [self getActiveUsers] Method which get data from database.


Then i make one class for make the contact object .

TKContact.h

@interface TKContact : NSObject {

    NSInteger sectionNumber;

    NSInteger recordID;

    BOOL rowSelected;

    NSString *name;

    NSString *email;

    NSString *tel;

    UIImage *thumbnail;

    NSString *lastName;

    NSString *firstName;

}

@property NSInteger sectionNumber;

@property NSInteger recordID;

@property BOOL rowSelected;

@property (nonatomic, retain) NSString *name;

@property (nonatomic, retain) NSString *email;

@property (nonatomic, retain) NSString *tel;

@property (nonatomic, retain) UIImage *thumbnail;

@property (nonatomic, retain) NSString *lastName;

@property (nonatomic, retain) NSString *firstName;

@property (nonatomic, retain) NSString *number;

- (NSString*)sorterFirstName;

- (NSString*)sorterLastName;

@end

TKContact.m

    }

Working with UIPasteboard

Hi friends in this tutorial  we will cover how to deal with UIPasteBoard.We will cover these much tasks:


1> Reading data  from general PasterBoard
2> Writing data to general PasteBoard
3> create Pasteboard
4> remove Pasteboard


1> Reading data from general PasteBoard

if you want to read string from general pasteboard

NSString *strName = [UIPasteboard generalPasteboard].string

2> Writing  data to general PasteBoard

 [[UIPasteboard generalPasteboard]setString:@"Mittal"];

 UIImage * image=[UIImage imageWithContentsOfFile:@"FILE_PATH"];
 UIPasteboard * pasteboard=[UIPasteboard generalPasteboard];
[pasteboard setImage:image];

//Method 2
NSData *imageData = UIImagePNGRepresentation(image);
[pasteboard setData:imageData forPasteboardType:(NSString *)kUTTypePNG];

You can also set dictionary to the clipboard this way,

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
pasteboard.persistent = NO;

NSMutableDictionary *text = [NSMutableDictionary dictionaryWithCapacity:1];
[text setValue:captionLabel.text forKey:(NSString *)kUTTypeUTF8PlainText];

NSMutableDictionary *image = [NSMutableDictionary dictionaryWithCapacity:1];
[image setValue:gratitudeImageView.image forKey:(NSString *)kUTTypePNG];

pasteboard.items = [NSArray arrayWithObjects:image,text, nil];


3> Create Custom PasteBoard

UIPasteboard *pasteboard = [UIPasteboard pasteboardWithName:@"customPasteBoard" create:YES];

 [pasteboard setPersistent:YES];
 //save the unique identifier string that we created earlier 
[pasteboard setString:@"Mittal"];

4> Remove PasteBoard

[UIPasteboard removePasteboardWithName:@"customPasteBoard"];
