    <p>I'm a beginner in iOS development so here is my question,</p> <p>i m trying to implement a simple battle ship game and i manually placed my ships into allCoordinates array, the first element is x coordinate , second element is y coordinate and third one is the size of the ship.</p> <p>The problem is; hit and missed must be increased just once for each try but when user enter 6th ship the hit became 1 and miss became 5 since the loop continue to check each row and increase miss.</p> <p>I can't just put a break after the missed++ so i m out of ideas here.</p> <p>Thank you :</p> <pre><code>for ( int i=0 ;i&lt;19;i++ ){ if ([self.xCoordinate.text isEqualToString:[allCoordinates objectAtIndex:i*3]] &amp;&amp; [self.yCoordinate.text isEqualToString:[allCoordinates objectAtIndex:i*3+1]] ) { NSLog(@"hit"); hit++; result.text = [NSString stringWithFormat:@"You hit %ix1 ship",[allCoordinates objectAtIndex:i*3+2]]; break; }else { NSLog(@"not hit"); result.text = [NSString stringWithFormat:@"You missed"]; missed++; } hitLabel.text = [NSString stringWithFormat:@"%i!",hit]; missed = missed%18; missedLabel.text = [NSString stringWithFormat:@"%i!",missed]; </code></pre> <p>and this is my array</p> <pre><code>allCoordinates = [[NSArray alloc] initWithObjects: @"15",@"2",@"3", @"13",@"2",@"3", @"14",@"2",@"3", @"10",@"7",@"3", @"11",@"7",@"3", @"12",@"7",@"3", @"16",@"8",@"3", @"16",@"9",@"3", @"16",@"10",@"3", @"3",@"4",@"4", @"4",@"4",@"4", @"5",@"4",@"4", @"6",@"4",@"4", @"9",@"10",@"4", @"9",@"11",@"4", @"9",@"12",@"4", @"9",@"13",@"4", @"5",@"14",@"1", @"18",@"17",@"1", nil]; </code></pre> <p>edit:i fixed it by putting an BOOL ishit after the for loop and it fixed my problem</p> <pre><code> if(ishit==YES){ hit++; }else { missed++; } </code></pre>

    2. COThis doesn't answer your question, but why are you using strings containing numbers rather than just numbers?

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.
