- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:  (NSInteger)section {
    return matchesProfileArr.count;;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    displayCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier
    forIndexPath:indexPath];

    if(!cell) {
        cell = [[displayCell alloc] initWithStyle:UITableViewCellStyleDefault
        reuseIdentifier:CellIdentifier];
    }

    NSMutableDictionary *dict= [matchesProfileArr objectAtIndex:indexPath.row];            
    NSMutableDictionary *dictdetails=[dict objectForKey:@"ABSAdvancedSearch"];

Just addition to the @Stefan and @balkaranSingh's answers. I think your @"age" key is holding NSNumber not NSString, for this reason convert it into string.

cell.lblAge.text = [[dictdetails objectForKey:@"age"] stringValue];

You are sending string to the image. You must load image from url like this: 

NSString *urlImage = [dictdetails objectForKey:@"profile_pic"];
cell.profileImage.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:urlImage]]];

EDIT: This is synchronous image loading.

I would like you to suggest you to user AFNetworking method for loading image from URL:

[cell. profileImage setImageWithURL:[NSURL URLWithString:urlImage]placeholderImage:[UIImage imageNamed:@"someImage"]];

OR: 

dispatch_async(dispatch_get_main_queue(), ^{

        cell.profileImage.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:urlImage]]];
    });

dispatch_async(dispatch_get_global_queue(0,0), ^{
    NSData * data = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString:[dictdetails objectForKey:@"profile_pic"]]];
    if ( data == nil )
        return;
    dispatch_async(dispatch_get_main_queue(), ^{

        cell.image = [UIImage imageWithData: data];
    });

});

plz use this code your ui will not get stuck if you use dispatch_async
