Re: Finding object array index when iterating through array

If you use a block-iterator, the index is passed as a parameter to the iterator block. Joar On 6 mar 2012, at 12:42, Prime Coderama wrote: > I have an array and I am iterating through it using this technique: > >> for (id object in array) { >>// do something with object >> } > > Is there

You have to add a counter. On 7 Mar, 2012, at 4:42, Prime Coderama wrote: > I have an array and I am iterating through it using this technique: > >> for (id object in array) { >>// do something with object >> } > > Is there way to obtain the object's current array index position or do

Re: Accessing array in thread safe way

No. The atomic just means you can access the array property atomically, not that methods called on that array are synchronized. For that you need to do your own synchronization, like using @synchronized on the array itself. On 7 Mar, 2012, at 3:51, "Jan E. Schotsman" wrote: > Hello, > > I

NSTableCellView subclass layout from independent nib

I have more than one table which will share a certain type of table cell. In cell-based table cells, I'd make an NSCell subclass, add whatever needed properties there are, and do all the drawing there. The layout of the cell is part of the subclass itself. In view-based tables, I'd create a NS

Re: Accessing array in thread safe way

I believe that reading is thread safe, but writing is not. You could wrap all access to the array in methods which use the same GCD queue to read/write, and that would be thread safe. Thanks, Jon On Mar 6, 2012, at 11:51 AM, Jan E. Schotsman wrote: > Hello, > > I have an array of progress v
