Body
I want to check that objects from array is same or not and if yes then i want to merge element. For that I have done this but I am getting error that : Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[__NSCFArray replaceObjectAtIndex:withObject:]: mutating method sent to immutable object' Array is: <pre><code>( ( hitesh, 121231, Hitesh, Patel, 3, 1, 0, 0, TGB ), ( hitesh, 121231, Hitesh, Patel, 3, 1, 0, 0, "The Fern" ) ) </code></pre> My Code is: <pre><code>-(void)compute:(NSMutableArray *)ary completion:(void (^)(void))completion{ int id=0; NSLog(@"Array is%@",ary); NSMutableArray *temp; for(int i=0;i<[ary count];i++){ temp=[ary objectAtIndex:i]; NSLog(@"string%@",[temp objectAtIndex:8]); if(id==[[temp objectAtIndex:4] integerValue]){ NSLog(@"inside"); NSMutableArray *temp1=[[NSMutableArray alloc]init]; temp1=[MyAppDelegate.searchResultArray objectAtIndex:i-1]; NSLog(@"temp1%@",temp1); NSString *tempStr=[[temp1 objectAtIndex:8] stringByAppendingString:[temp objectAtIndex:8]]; NSLog(@"%@",tempStr); [temp1 replaceObjectAtIndex:8 withObject:tempStr]; [MyAppDelegate.searchResultArray replaceObjectAtIndex:i-1 withObject:temp1]; } else{ id=[[temp objectAtIndex:4] integerValue]; NSLog(@"temp is%@ %d",temp,id); [MyAppDelegate.searchResultArray addObject:temp]; } } NSLog(@"%@",MyAppDelegate.searchResultArray); } </code></pre> Another issue is that After Completing this process I want to navigate page. Thats why I have written this method: <pre><code>-(void)compute:(NSMutableArray *)ary completion:(void (^)(void))completion{ } </code></pre> and I am doing this: <pre><code>[self compute:[root valueForKey:@"searchResult"] completion:^{ NSLog(@"after co"); [self.navigationController pushViewController:SearchResultVC animated:YES]; }]; </code></pre> Should I have to return anything from method?

Guidance

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.
