Status:Duplicate of 22182367 Resolved:23-Sep-2015 04:12 PM
Product:OS X Product Version:Mac OS X 10.10.3 (14D136)
Classification:Serious Bug Reproducible:Always
 
Summary:
NSDateIntervalFormatter shows both dates AND times even when dateStyle is set to NSDateFormatterNoStyle.

Steps to Reproduce:
1. Open the attached sample project.
2. Build and run.

Expected Results:
The final NSLog statement prints out “9:00 PM - 12:00 AM”

Actual Results:
The final NSLog statement prints out “5/12/2015, 9:00 PM - 5/13/2015, 12:00 AM”

Regression:
new class in 10.10

Notes:
There appears to be some undefined/erratic behavior going on here. If you run the sample code at http://stackoverflow.com/a/30202745/255489 you will see that it works if endDate is one day BEFORE startDate, but not if it is 2 days before.
