Find difference in days in Java

To calculate the difference between two dates, we will be using Calendar (java.util.*)


public static long daysDifference(Calendar startDate, Calendar endDate)
{
Calendar date = (Calendar) startDate.clone();
long daysBetween = 0;
while (date.before(endDate))
{
date.add(Calendar.DAY_OF_MONTH, 1);
daysBetween++;
}
return daysBetween;
}


The while loop will be executed until the startDate is less than the endDate. The long value daysBetween will return the days difference.

Multiple line of text in UIPickerView

But, by default, only one line of text is allowed to be displayed in a UIPickerView . Today, we will try to add multi-line text to an UIPickerView . To do so, we need to implement the viewForComponent api.   - ( UIView  *)pickerView:( UIPickerView  *)pickerView viewForRow:( NSInteger )row forComponent:( NSInteger )component reusingView:( UIView  *)view; In that method, type cast the view parameter to an UILabel.    UILabel *pickerLabel = ( UILabel *)view; Update the frame size of the label.    CGRect frame = CGRectMake ( 0 , 0 , 265 , 40 );    pickerLabel = [[[ UILabel alloc ] initWithFrame :frame] autorelease ]; Set the properties of the label as per requirement.    [pickerLabel setTextAlig...

Custom Message extension using Messages SDK - iMessage App store

We used images and using Messages SDK, we are able to create the custom extension for sticker. We also created a basic sticker extension in this article . Apple Messages SDK provides lot more features than just creating stickers. In today's article, we will create a custom message extension using Messages SDK and run them on iMessage app store. Before diving in to the project, lets look at the classes provided by Apple for implementation. MSMessagesAppViewController The MSMessagesAppViewController class acts as the principal view controller for Messages extensions. Use this class to manage your extension. MSMessageTemplateLayout The MSMessageTemplateLayout describes how an MSMessage object is presented in the transcript. The message template includes the Message extension’s icon, an image, video, or audio file, and a number of text elements (title, subtitle, captio...
