2014-06-19 09:51:57.447 yelp[15415:70b] fetching businesses 2014-06-19 09:51:57.483 yelp[15415:70b] view loaded 2014-06-19 09:51:57.485 yelp[15415:70b] businesses count (for cell view): 0 2014-06-19 09:51:57.486 yelp[15415:70b] businesses count (for cell view): 0 2014-06-19 09:51:57.487 yelp[15415:70b] businesses count (for cell view): 0 2014-06-19 09:51:57.487 yelp[15415:70b] businesses count (for cell view): 0 2014-06-19 09:51:57.487 yelp[15415:70b] businesses count (for cell view): 0 2014-06-19 09:51:57.900 yelp[15415:70b] businesses count (after fetch): 20

questions - seems fetching info asynchronous, lastly line

2014-06-19 09:51:57.900 yelp[15415:70b] businesses count (after fetch): 20 but meanwhile cellforrowatindexpath called , info nil

how handle situation create sure cellforrowatindexpath called when have data?

i using [self.searchresulttableview reloaddata]; not sure if doing right thing

cellforrowatindexpath beingness called because told table there cells display.

this...

- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { homecoming 5; }

should be...

- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { homecoming self.businesses.count; }

ios objective-c uitableview
