i am currently having some problem with my UITableView, this is the first time I am putting thumbnail in my table view cell and also integrating NSThread to load thumbnail image, so, please bare with me. Thanks<\/p>\n
I am downloading the data and setting up the cells like usual, but this time with the NSThread added.<\/p>\n
First I will call ASIHTTPRequest in my view did load<\/p>\n
Then in – (void)requestFinished:(ASIHTTPRequest *)request I will add the url of the thumbnail into an NSMutableArray<\/p>\n
NSString *photoURLString = [NSString stringWithFormat:@\"http:\/\/some.url.com\/img\/%@\",[thearray objectForKey:@\"tn_url\"]]; \n[thumbNailURL addObject:(photoURLString)];\n<\/code><\/pre>\nAnd in the cellForRowAtIndexPath: where I am setting up other data to display, I will call my NSThread<\/p>\n
[NSThread detachNewThreadSelector:@selector(loadImage:) toTarget:self withObject:indexPath];\n<\/code><\/pre>\nAnd in my loadImage thread<\/p>\n
- (void) loadImage: (NSIndexPath*) indexPath{\nNSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];\nNSString *iconURL = [thumbNailURL objectAtIndex:indexPath.row];\nNSURL *url = [NSURL URLWithString:iconURL]; \nUIImage *icon = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];\ncellImageView = [[UIImageView alloc] initWithFrame:CGRectMake(11.0, 6.0, 61.0, 50.0)];\n[cellImageView setImage:icon];\nUITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];\n[cell.contentView performSelectorOnMainThread:@selector(addSubview:) withObject:cellImageView waitUntilDone:NO];\n[pool drain];\n<\/code><\/pre>\n}<\/p>\n
All the data and image loaded just fine, but if I scroll faster up and down , the application will hang with the following error<\/p>\n
[1997:7a1f] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 6 beyond bounds [0 .. 5]' (0x31312d2f 0x345f50e3 0x3127d1b1 0x35aefc1d 0xf4dd 0x333ffb51 0x3347c67b 0x366af589 0x366b2310) terminate called throwing an exceptionProgram received signal: \"SIGABRT\".\n<\/code><\/pre>\nIt would be great if anyone could show me the correct configuration if I am wrong, as I have been trying different approches for the past 3 days already. Thank you so much.<\/p>\n","protected":false},"excerpt":{"rendered":"
