Example Usage

In the package is included an example to use this class.

The best thing to do, is to extend the MGSpotyViewController. In the package see the class MGViewController.{h,m} as example.

Here the explanation:

Init is easy. You have just to pass the main image for the blur effect:

MGViewController *spotyViewController = [[MGViewController alloc] initWithMainImage:[UIImage imageNamed:@"example"]];

MGViewController extends MGSpotyViewController:

//
//  MGViewController.h
//  MGSpotyView
//

//

#import "MGSpotyViewController.h"

@interface MGViewController : MGSpotyViewController


@end

In the implementation file, first of all you should set the overView. The overView is basically the header view which remains over the blur image:

- (void)viewDidLoad {
    [self setOverView:self.myOverView];
}


//This is just an example view created by code, but you can return any type of view.
- (UIView *)myOverView {
    UIView *view = [[UIView alloc] initWithFrame:self.overView.bounds];

    //Add an example imageView
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(view.center.x-50.0, view.center.y-60.0, 100.0, 100.0)];
    [imageView setContentMode:UIViewContentModeScaleAspectFill];
    [imageView setClipsToBounds:YES];
    [imageView setImage:[UIImage imageNamed:@"example"]];
    [imageView.layer setBorderColor:[UIColor whiteColor].CGColor];
    [imageView.layer setBorderWidth:2.0];
    [imageView.layer setCornerRadius:imageView.frame.size.width/2.0];

    //Add an example label
    UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(view.center.x-120.0, view.center.y+50.0, 240.0, 50.0)];
    [lblTitle setText:@"Name Surname"];
    [lblTitle setFont:[UIFont boldSystemFontOfSize:25.0]];
    [lblTitle setTextAlignment:NSTextAlignmentCenter];
    [lblTitle setTextColor:[UIColor whiteColor]];


    [view addSubview:imageView];
    [view addSubview:lblTitle];

    return view;
}

The best overView to set should be a squared view with transparent background, with the same width and height of self.overView which is a flexible container view in the class MGSpotyViewController. Width and height are so equal and they correspond with the width of the screen.

So for a classic iPhone the best frame would be: {0, 0, 320.0, 320.0} with flexible width and height.

But to make the size adaptable to the screen starting from the first time, the best thing to do would be set the same bounds of the property self.overView.

For this reason you see the line:

UIView *view = [[UIView alloc] initWithFrame:self.overView.bounds];

The other thing to configure is the tableView. The tableView is already in the MGSpotyViewController, you have just to override the UITableViewDelegate and UITableViewDatasource methods.

You have just to remember that the section 0 is reserved, so you have to return 1 section in more and managing only your sections (section > 0):

#pragma mark - UITableView Delegate & Datasource

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    NSInteger mySections = 1;

    return mySections + 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {    
    if (section == 1)
        return 20;

    return 0;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *identifier = @"CellID";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

    if(!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
        [cell setBackgroundColor:[UIColor darkGrayColor]];
        [cell.textLabel setTextColor:[UIColor whiteColor]];
    }

    [cell.textLabel setText:@"Cell"];

    return cell;
}

And, if you need to manage sections header title or sections header view, for the section 0 you should call the superclass method, like in the example below:

//Here call the superclass method
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    if(section == 0)
        return [super tableView:tableView viewForHeaderInSection:section];

    return nil;
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
    if(section == 1)
        return @"My Section";

    return nil;
}

//Here call the superclass method
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    if(section == 0)
        return [super tableView:tableView heightForHeaderInSection:section];

    if(section == 1)
        return 20.0;

    return 0.0;
}
