copied!<p>Hi I m creating a project where multiple Images Loading from Server With some like Count and Comment Count and a Button to like the image. I m showing the individual Images With using a Slider Controller like PageControl.</p> <p>this is My code for Showing the View</p> <pre><code>-(UIView*)reloadView:(DPSliderView *)sliderView viewAtIndex:(NSUInteger)idx { _loading_view.hidden=TRUE; if (idx < [photos count]) { NSDictionary *item = [photos objectAtIndex:idx]; PhotoView *v = [[PhotoView alloc] init]; v.photoIndex = idx; v.imageView.imageURL = [DPAPI urlForPhoto:item[@"photo_220x220"]]; NSString *placename1 = [item valueForKeyPath:@"spotting.item.name"]; NSString *firstCapChar1 = [[placename1 substringToIndex:1] capitalizedString]; NSString *cappedString1 = [placename1 stringByReplacingCharactersInRange:NSMakeRange(0,1) withString:firstCapChar1]; v.spotNameLabel.text = cappedString1; NSString *placename = [item valueForKeyPath:@"spotting.place.name"]; NSString *firstCapChar = [[placename substringToIndex:1] capitalizedString]; NSString *cappedString = [placename stringByReplacingCharactersInRange:NSMakeRange(0,1) withString:firstCapChar];

int cap_len=[place1 length]; int address_lenth=[address length]; ZMutableAttributedString *str = [[ZMutableAttributedString alloc] initWithString:location_str3 attributes:[NSDictionary dictionaryWithObjectsAndKeys: [[FontManager sharedManager] zFontWithName:@"Lucida Grande" pointSize:12], ZFontAttributeName, nil]]; [str addAttribute:ZFontAttributeName value:[[FontManager sharedManager] zFontWithName:@"Lucida Grande" pointSize:12] range:NSMakeRange(0, cap_len+3)]; [str addAttribute:ZForegroundColorAttributeName value:[UIColor colorWithRed:241/255.0f green:73.0/255.0f blue:2.0/255.0f alpha:1.0]range:NSMakeRange(0, cap_len+3)];

} else { CLLocation *location1 = [[CLLocation alloc] initWithLatitude:[[item valueForKeyPath:@"spotting.place.lat"]floatValue] longitude:[[item valueForKeyPath:@"spotting.place.lng"] floatValue]]; CLLocation *location2 = [[CLLocation alloc] initWithLatitude:[_explore_lat_str floatValue] longitude:[_explore_lng_str floatValue]]; NSString *lat_laong=[NSString stringWithFormat:@"%f",[location1 distanceFromLocation:location2]]; int km=[lat_laong floatValue]*0.001; NSString *distancestr=[NSString stringWithFormat:@"%d km",km]; float dist=[distancestr floatValue]; v.distanceLabel.text = [NSString stringWithFormat:@"%.2f km", dist]; } if (![item[@"likes"] boolValue]) { v.likeButton.enabled = YES; v.likeButton.tag = idx; [v.likeButton setImage:[UIImage imageNamed:@"like_new.png"] forState:UIControlStateNormal];

} NSArray *guides = item[@"guides"]; if ([guides count] > 0) { NSString *guideType = [[guides objectAtIndex:0] valueForKey:@"type"]; UIImage *guidesIcon = [UIImage imageNamed:[NSString stringWithFormat:@"%@.png", guideType]]; v.guideButton.hidden = NO; v.guideButton.tag = idx; [v.guideButton setImage:guidesIcon forState:UIControlStateNormal]; [v.guideButton addTarget:self action:@selector(guideAction:) forControlEvents:UIControlEventTouchUpInside]; } v.shareButton.tag = idx; [v.shareButton addTarget:self action:@selector(shareAction:) forControlEvents:UIControlEventTouchUpInside]; UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(photoTapGesture:)]; [v addGestureRecognizer:tapGesture]; [tapGesture release]; return [v autorelease]; } else { UIImageView *iv = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sc_img.png"]]; UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]; indicator.center = CGPointMake(CGRectGetMidX(iv.bounds), 110); [indicator startAnimating]; [iv addSubview:indicator]; [indicator release]; return [iv autorelease]; } } </code></pre> <p>Now My question is :</p> <p>If i will Click on Like Button , Then i have to change the button image as well as like count. I can able to Change the Button Image By This Method </p> <pre><code>[sender setImage:[UIImage ImageNamed:@"image.png"]]; </code></pre> <p>But How can I change the Like count of the Label ? How can i access the Particular label of the View ? I have assigned the tag But , I dont know how to assign it.I dont want to Reload Whole Slider as the Photo are loading from Network (Remote Server) . Thanks for your Time. </p>
