depth loop an array use block or something others - ios

Question

I had an comments array, witch contains the comment message and the reply message and follow the reply message.want to show all the messages orderly, seems its An infinite loop.
My code is like below:
if (self.commentArray.count > 0) {
//comments
NSDictionary *message = [self.commentArray objectAtIndex:indexPath.row];
if ([FHWServiceManager isValidObject:[message objectForKey:#"UserIcon"]]) {
[cell.photoImageView setImageWithURL:[NSURL URLWithString:[message objectForKey:#"UserIcon"]] placeholderImage:[UIImage imageNamed:#"face_poor"]];
}else {
cell.photoImageView.image = [UIImage imageNamed:#"face_poor"];
}
cell.photoImageView.layer.cornerRadius = 15;
cell.photoImageView.layer.masksToBounds = YES;
cell.nameLabel.text = [message objectForKey:#"Username"];
cell.nameLabel.textColor = UIColorFromRGB(0xbf6327);
cell.contentLabel.text = [message objectForKey:#"Comment"];
cell.timeLabel.text = [DateUtil timePassedDescriptionFor:[DateUtil dateFromRFC3339DateString:[message objectForKey:#"CreateTime"]]];
//follow comment
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"PId == %d",[[message objectForKey:#"Id"] intValue]];
NSArray *tempArray = [self.replyCommentArray filteredArrayUsingPredicate:predicate];
if (tempArray.count > 0) {
UIImageView *triangleImageView = [[UIImageView alloc] initWithFrame:CGRectMake(67, 80, 10, 5)];
triangleImageView.image = [UIImage imageNamed:#"comment_reply_arrow_top"];
[cell.contentView addSubview:triangleImageView];

Try this, this may not be the exact solution. But you can follow this approach with some minor changes
- (NSArray *) replyforPid:(int) pID {
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"PId == %d",pID];
NSArray *tempArray = [self.replyCommentArray filteredArrayUsingPredicate:predicate];
return tempArray;
}
- (void) addReplyInView:(UIView *) followBackView forPid:(int) pID lastHeight:(float) lastHeight {
NSArray *tempArray = [self replyforPid:pID];
if ([tempArray count] > 0) {
if (lastHeight != 0) {
float height = followBackView.frame.size.height;
height += 21*subTempArray.count;
followBackView.frame = CGRectMake(followBackView.frame.origin.x, followBackView.frame.origin.y, followBackView.frame.size.width, height);
}
for (int i = 0; i < tempArray.count; i ++) {
NSDictionary *replyMessage = [tempArray objectAtIndex:i];
NSString *replyStr;
replyStr = [NSString stringWithFormat:#"%#: %#",[replyMessage objectForKey:#"Username"],[replyMessage objectForKey:#"Comment"]];
TTTAttributedLabel *followCommentLabel = [[TTTAttributedLabel alloc] initWithFrame:CGRectMake(5, lastHeight + 5, followBackView.frame.size.width, 21)];
followCommentLabel.font = [UIFont systemFontOfSize:13];
followCommentLabel.textColor = [UIColor darkGrayColor];
followCommentLabel.backgroundColor = [UIColor clearColor];
[followCommentLabel setText:replyStr afterInheritingLabelAttributesAndConfiguringWithBlock:^ NSMutableAttributedString *(NSMutableAttributedString *mutableAttributedString) {
