i have variable defined here:
const sdatagridcoord *clickedgridcoord; and populating in method:
- (void)shinobidatagrid:(shinobidatagrid *)grid willselectcellatcoordinate:(const sdatagridcoord *)gridcoordinate { if ((gridcoordinate.column.displayindex==5||gridcoordinate.column.displayindex == 6 || gridcoordinate.column.displayindex == 7 ) && datasource.datafordatabase) { clickedgridcoord = gridcoordinate; [self createcelldatemodpopup:gridcoordinate]; } } and used break point , see being populated.
but when goto call it, empty:
celldata *cell = [datasource.cellholder objectatindex:clickedgridcoord.row]; and empty mean there no row or column, there when first populate sdatagridcoord.
what doing wrong, there nothing else overriding variable.
i have tried this:
sdatagridcoord *clickedgridcoord; then
- (void)shinobidatagrid:(shinobidatagrid *)grid willselectcellatcoordinate:(const sdatagridcoord *)gridcoordinate { if ((gridcoordinate.column.displayindex==5||gridcoordinate.column.displayindex == 6 || gridcoordinate.column.displayindex == 7 ) && datasource.datafordatabase) { clickedgridcoord = (sdatagridcoord *)gridcoordinate; [self createcelldatemodpopup:gridcoordinate]; } } still same result , app still crashes: thread 1:exc_bad_access (code = 1, address=0xc000000c)
my .m file:
@interface controller() { sdatagridcoord *clickedgridcoord; } @implementation controller - (void)shinobidatagrid:(shinobidatagrid *)grid willselectcellatcoordinate:(const sdatagridcoord *)gridcoordinate { if ((gridcoordinate.column.displayindex==5||gridcoordinate.column.displayindex == 6 || gridcoordinate.column.displayindex == 7 ) && datasource.datafordatabase) { clickedgridcoord = (sdatagridcoord *)gridcoordinate; [self createcelldatemodpopup:clickedgridcoord]; } } - (void)changecellwithstringdate :(nsstring *)stringdate { //my app crashes here error: thread 1:exc_bad_access (code = 1, address=0xc000000c) celldata *cell = [datasource.cellholder objectatindex:clickedgridcoord.row.rowindex]; }
are using pre-arc library? if suspect (and mean code) manually releasing 1 more time object referenced gridcoordinate.
this cause object deallocated , end reference wrong memory location (because object gone).
if have source code of sdatagridcoord please add breakpoint in dealloc method , if gets called before try use object in
- (void)changecellwithstringdate :(nsstring *)stringdate finally, if happening should create sdatagridcoord object (a copy yours) , assigning ivar. managed arc , fine.
