[28] | 13 | /* Bugs to file:
|
---|
[21] | 14 |
|
---|
[28] | 15 | ¥ any trailing spaces: -> exception for +[NSCalendarDate dateWithNaturalLanguageString]:
|
---|
| 16 | > NSCalendarDate dateWithNaturalLanguageString: '12 '
|
---|
| 17 | format error: internal error
|
---|
[21] | 18 |
|
---|
[28] | 19 | ¥ NSDate natural language stuff in NSCalendarDate (why?), misspelled category name
|
---|
| 20 | ¥ NSCalendarDate natural language stuff behaves differently from NSDateFormatter (AM/PM has no effect, shouldn't they share code?)
|
---|
| 21 | ¥ NSDateFormatter doc class description gives two examples for natural language that are incorrect, no link to NSDate doc that describes exactly how natural language dates are parsed
|
---|
| 22 | ¥ NSTimeFormatString does not include %p when it should, meaning that AM/PM is stripped yet 12-hour time is still used
|
---|
| 23 | ¥ NSNextDayDesignations, NSNextNextDayDesignations are noted as 'a string' in NSUserDefaults docs, but maybe they are actually an array, or either an array or a string, given their names?
|
---|
| 24 | ¥ "Setting the Format for Dates" does not document how to get 1:15 AM, the answer is %1I - strftime has no exact equivalent; the closest is %l. strftime does not permit numeric prefixes. It also refers to "NSCalendar" when no such class exists.
|
---|
| 25 | ¥ none of many mentions of NSAMPMDesignation indicates that they include the leading spaces (" AM", " PM"). In "Setting the Format for Dates", needs to mention that the leading spaces are not included in %p with strftime. But if you use the NSCalendarDate stuff, it appears %p doesn't include the space.
|
---|
| 26 | ¥ descriptions for %X and %x are reversed (time zone is in %X, not %x)
|
---|
| 27 | ¥ too hard to implement date-only or time-only formatters
|
---|
| 28 | ¥ should be able to specify that natural language favors date or time (10 = 10th of month, not 10am)
|
---|
| 29 | ¥ please expose the iCal controls!
