    <p>Here i am getting current time and check whether its in am/pm format. If its not like that, i convert 24 hour time format into 12 hour time format and add AM/PM manually.</p> <p>This is my code:</p> <pre><code>- (NSString *) getCurrentTime { NSDate *today = [NSDate date]; NSDateFormatter *timeFormatter = [[NSDateFormatter alloc] init]; [timeFormatter setDateFormat:@"hh:mm:ss a"]; NSString *currentTime = [timeFormatter stringFromDate:today]; currentTime = [self checkTimeFormat:currentTime]; return currentTime; } </code></pre> <p>And</p> <pre><code> - (NSString *) checkTimeFormat:(NSString *) currentTime { NSArray *timeArray = [currentTime componentsSeparatedByString:@":"]; int intHour = [[timeArray objectAtIndex:0] intValue]; NSString *lastVal = [timeArray objectAtIndex:2]; if ([lastVal rangeOfString:@"M"].location == NSNotFound) { if (intHour &lt; 12) lastVal = [NSString stringWithFormat:@"%@ AM", [timeArray objectAtIndex:2]]; else lastVal = [NSString stringWithFormat:@"%@ PM", [timeArray objectAtIndex:2]]; } if (intHour &gt; 12) intHour = intHour - 12; currentTime = [NSString stringWithFormat:@"%d:%@:%@", intHour, [timeArray objectAtIndex:1], lastVal]; NSLog(@"Current Time ==&gt;&gt; %@", currentTime); return currentTime; } </code></pre> <p>Conversion of NSString into NSDate code below:</p> <pre><code>NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"hh:mm:ss a"]; NSDate *testDate = [dateFormatter dateFromString:getCurrentTime]; NSLog(@"testDate =&gt; %@", testDate); </code></pre> <p>If the Time is in 12 hour format (am/pm), testDate value is getting correctly.</p> <p>If the Time is in 24 hour format, testDate value is <strong>null</strong></p> <p>What is the issue?</p> <p>Thanks in Advance.</p>

    1. COWhat should method `getCurrentTime` return? Do you want it to return a time in a 12-hour format regardless of user's locale?

    2. COI need to get current time in NSDate Time Format such like (1999-12-31 18:54:30 +0000). After that i will calculate timeIntervalSinceDate between two NSDate. Here getCurrentTime returns formatted current time in NSString (Ex: 11:09:14 PM).

    3. COI'm still not sure what you're trying to achieve. What `checkTimeFormat` should do?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
