Set and get Date in NSString format or NSDate format with different date format with my bellow method

You can get date with string return type and also set date format in which you want to get date For Ex: dd-MMM-yyyy (i.e. 05-Mar-2014)

-(NSString *)changeDateFormat:(NSString*)stringDate dateFormat:(NSString*)dateFormat getwithFormat:(NSString *)getwithFormat{

    

    

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

    [dateFormatter setDateFormat:dateFormat];

    

    NSDate *date = [dateFormatter dateFromString:stringDate];

    [dateFormatter setDateFormat:getwithFormat];

    

    NSString *convertedString = [dateFormatter stringFromDate:date];

    NSLog(@"Converted String : %@",convertedString);

    return convertedString;

}

NSString  *stringVar  = [self changeDateFormat:yourDateString dateFormat:@"yyyy-MM-dd" getwithFormat:@"dd MMM yyyy"];// set your date string and its date format and after set your required new date format

You can get date with NSDate return type and also set date format in which you want to get date For Ex: dd-MMM-yyyy (i.e. 05-Mar-2014) same like above but here you get return date in NSDate.

-(NSDate *)convertStringToDate:(NSString *)date dateFormat:(NSString *)dateFormat getWithFormat:(NSString *)getWithFormat {

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

    NSDate *nowDate = [[NSDate alloc] init];

    [formatter setDateFormat:dateFormat];// set format here which format in string date

    date = [date stringByReplacingOccurrencesOfString:@"+0000" withString:@""];

    nowDate = [formatter dateFromString:date];

    [formatter setDateFormat:getWithFormat];

    

    NSString *convertedString = [formatter stringFromDate:nowDate];

    nowDate = [formatter dateFromString:convertedString];

    // NSLog(@"date============================>>>>>>>>>>>>>>> : %@", nowDate);

    return nowDate;

}

set size of UILable with its content text

With my bellow method you can set UILable size with its content text.

-(CGRect)setDynamicHeight:(UILabel *)lbl{

    CGRect myLabelFrame = [lbl frame];

  

    NSString *text = lbl.text;

    CGFloat width = lbl.frame.size.width;

    UIFont *font = lbl.font;

    NSAttributedString *attributedText =

    [[NSAttributedString alloc]

     initWithString:text

     attributes:@

     {

     NSFontAttributeName: font

     }];

    CGRect rect = [attributedText boundingRectWithSize:(CGSize){width, CGFLOAT_MAX}

                                               options:NSStringDrawingUsesLineFragmentOrigin

                                               context:nil];

    CGSize size = rect.size;

    

    myLabelFrame.size.height = size.height;

    

    return myLabelFrame;

}

and use this method with my bellow code

    [yourLable setFrame:[self setDynamicHeight:yourLable]];

How to add animation in View for any view or any Control.

With bellow code you can set animation for any control or any view...

        CATransition *animation = [CATransition animation];

        [animation setDuration:1.0];// Set Duration

        [animation setType:kCATransitionPush];

        [animation setSubtype:kCATransitionFromTop];// set different type of Transition

        [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

        

        [[yourView layer] addAnimation:animation forKey:@"SwitchToView1"];// here you can set any view or any Control For Ex: UITableViewCell

Get Date and Time difference with different format with my custom method

You can get difference with bellow code

   NSString *strDifference = [self getDateDifferencewithTimeDay:yourOldDateString strDate2:[self StringFromDate:[NSDate date]]];

NSLog(@"\n Difference  =====>> %@", strDifference);

 Here i set old string and current string to get difference between that both dates.

Here i use two methods in above code one is getDateDifferencewithTimeDay for get difference between that dates and second is StringFromDate for get data in string format.

-(NSString *)getDateDifferencewithTimeDay:(NSString *)strDate1 strDate2:(NSString *)strDate2{

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

    

    NSDate *Date1;

    NSDate *Date2;

    NSString *strAnswer;

    

    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

    

    Date1 = [formatter dateFromString:strDate1];

    Date2 = [formatter dateFromString:strDate2];

    

    NSTimeInterval timeDifference = [Date2 timeIntervalSinceDate:Date1];

    

    double minutes = timeDifference / 60;

    

    double hours = minutes / 60;

    

    double seconds = timeDifference;

    

    double days = minutes / 1440;

    

    if (seconds < 60) {

        strAnswer = [NSString stringWithFormat:@"%.0f Seconds ago.",seconds];

    }

    else if (minutes < 60){

        strAnswer = [NSString stringWithFormat:@"%.0f Minutes ago.",minutes];

    }

    else if (hours < 24){

        strAnswer = [NSString stringWithFormat:@"%.0f Hours ago.",hours];

    }

    else{

        strAnswer = [NSString stringWithFormat:@"%.0f Days ago.",days];

    }

    return strAnswer;

}

And also this bellow method is for convert NSDate to NSString format

-(NSString *)StringFromDate:(NSDate *)DateLocal{

    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];

    [dateFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

    NSString *dateString = [dateFormat stringFromDate:DateLocal];

    NSLog(@"Date is HERE  =====>> %@",dateString);

    return dateString;

}

=> In this above method if your location not found then you get lat-long 0.0000

you can use above method it like bellow...

NSLog(@"Location:%f && %f",objLocaton.latitude, objLocaton.longitude);
