    <p>I am having a double value that represents a <code>NSTimeInterval</code>. I want to create the correct date from the double value, here is my code. I am getting the output, but there is some changes from the actual value.</p> <pre><code>NSString *modiDate = [NSString stringWithFormat:@"1338229800"]; //example time interval value NSNumber *time = [NSNumber numberWithDouble:([modiDate doubleValue] - 3600)]; NSTimeInterval interval = [time doubleValue]; NSDate *online = [NSDate date]; online = [NSDate dateWithTimeIntervalSince1970:interval]; NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [dateFormatter setDateFormat:@"MM/dd/yyyy HH:mm:ss aaa"]; NSLog(@"result: %@", [dateFormatter stringFromDate:online]); </code></pre> <p>What went wrong here? Any idea?</p> <p><strong>EDIT:</strong> For testing first i converted a date to <code>NSTimeInterval</code> and tried to get back the date. Here is the code and output.</p> <pre><code>NSString *modDate = [NSString stringWithFormat:@"5/30/2012 2:02:55 PM"]; NSDateFormatter *format = [[NSDateFormatter alloc]init]; [format setDateFormat:@"MM/dd/yyyy HH:mm:ss aaa"]; NSDate *dateFromString1 = [[NSDate alloc] init]; dateFromString1 = [format dateFromString:modDate]; [format release]; NSTimeInterval timeInterval1 = [dateFromString1 timeIntervalSince1970]; NSLog(@"timeinterval : %f",timeInterval1); NSDate *online = [NSDate date]; online = [NSDate dateWithTimeIntervalSince1970:timeInterval1]; NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [dateFormatter setDateFormat:@"MM/dd/yyyy HH:mm:ss aaa"]; NSLog(@"result: %@", [dateFormatter stringFromDate:online]); </code></pre> <p>and the output is:</p> <pre><code> result: 05/30/2012 12:02:55 PM actual date:5/30/2012 2:02:55 PM </code></pre>

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.
