How to Access Particular view of a pageControl viewController? - iphone

Question

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.
this is My code for Showing the View
-(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];
NSString *place1=[NSString stringWithFormat:#"%#",cappedString];
NSString *address=[NSString stringWithFormat:#"%#",[item valueForKeyPath:#"spotting.place.address"]];
NSString *location_str3 = [NSString stringWithFormat:#"# %#, %#",place1,address];
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)];
[str addAttribute:ZForegroundColorAttributeName value:[UIColor colorWithRed:128.0/255.0f green:121.0/255.0f blue:98.0/255.0f alpha:1.0]range:NSMakeRange(cap_len+4, address_lenth)];
v.placefontlabel.zAttributedText=str;
v.likesCountLabel.text = [NSString stringWithFormat:#"%i", [item[#"likes_count"] intValue]];
if ([_device_lang_str isEqualToString:#"es"])
{
v.shightingsLabel.text = [NSString stringWithFormat:NSLocalizedString(#"%i Vistas", nil), [item[#"sightings_count"] intValue]];
}
else
{
v.shightingsLabel.text = [NSString stringWithFormat:NSLocalizedString(#"%i Sightings", nil), [item[#"sightings_count"] intValue]];
}
if ([nolocationstr isEqualToString:#"YES"])
{
v.distanceLabel.text =[NSString stringWithFormat:#"%.2f km", [item[#"distance"] floatValue]];
}
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];
[v.likeButton addTarget:self action:#selector(likeAction:) forControlEvents:UIControlEventTouchUpInside];
}
else
{
v.likeButton.tag = idx;
[v.likeButton setImage:[UIImage imageNamed:#"like_new1.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];
}
}
Now My question is :
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
[sender setImage:[UIImage ImageNamed:#"image.png"]];
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.

Answer 1

Just keep a reference to the label and update that.
// #interface
#property (nonatomic, strong) UILabel *myLabel;
// #implementation
_myLabel.text = #"Whatever.";
If you have multiple labels, set the tags when you create your views
newView.tag = sequenceNumber +100;
And then update
-(void)updateLabelWithTag:(NSInteger)tag {
UILabel *label = (UILabel*) [self.scrollView viewWithTag:tag];
label.text = #"Whatever.";
}
