MGSpotyViewController
=====================
Beautiful viewController with a tableView and amazing effects like a viewController in the Spotify app.
With MGSpotyViewController you can implement several layouts like these:
## Info
This code must be used under ARC.
If your code doesn't use ARC you can [mark this source with the compiler flag](http://www.codeography.com/2011/10/10/making-arc-and-non-arc-play-nice.html) `-fobjc-arc`
## 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:
``` objective-c
MGViewController *spotyViewController = [[MGViewController alloc] initWithMainImage:[UIImage imageNamed:@"example"]];
```
`MGViewController` extends `MGSpotyViewController`:
``` objective-c
//
// MGViewController.h
// MGSpotyView
//
// Created by Matteo Gobbi on 25/06/2014.
// Copyright (c) 2014 Matteo Gobbi. All rights reserved.
//
#import "MGSpotyViewController.h"
@interface MGViewController : MGSpotyViewController
@end
```
Set the `delegate` and the `datasource` of the `MGSpotyViewController`:
```objective-c
- (instancetype)init
{
if (self = [super init]) {
self.dataSource = myDataSource; //Or self
self.delegate = myDelegate; //Or self
}
return self;
}
```
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:
``` objective-c
- (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;
}
```
Another thing to configure is the `tableView`. The `tableView` is already in the `MGSpotyViewController`, you have just to set the `MGSpotyViewControllerDataSource` and `MGSpotyViewControllerDelegate` and use their methods.
You must remember that the section 0 is reserved, so even if you will return 1 section, your delegate will get called for section number 1, not 0. Basically for sections the counter doesn't start from 0 but from 1:
``` objective-c
#pragma mark - MGSpotyViewControllerDataSource
- (NSInteger)numberOfSectionsInSpotyViewController:(MGSpotyViewController *)spotyViewController
{
return 1;
}
- (NSInteger)spotyViewController:(MGSpotyViewController *)spotyViewController
numberOfRowsInSection:(NSInteger)section
{
return 20;
}
- (UITableViewCell *)spotyViewController:(MGSpotyViewController *)spotyViewController
tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// IndexPath is 1-1, 1-2, 1-3 etc.
UITableViewCell *cell = // Your cell initialisation
return cell;
}
```
And, if you need to manage sections header title or sections header view:
```objective-c
#pragma mark - MGSpotyViewControllerDelegate
- (CGFloat)spotyViewController:(MGSpotyViewController *)spotyViewController
heightForHeaderInSection:(NSInteger)section
{
return 20.0;
}
- (NSString *)spotyViewController:(MGSpotyViewController *)spotyViewController
titleForHeaderInSection:(NSInteger)section
{
return @"My Section";
}
```
## Customisations
There are a bunch of properties you can play with to get the best result for your needs:
``` objective-c
/**
* The tint color on top of the blur. When alpha is 1.0
* you'll not be able to see the image behind.
*/
@property (nonatomic, strong) UIColor *tintColor;
/**
* Indicate if the overView has to fade out when scrolling up
* Default value: NO
*/
@property (atomic) BOOL overViewFadeOut;
/**
* Indicate if the main image has to get unblurred when scrolling down
* Default value: YES
*/
@property (atomic) BOOL shouldUnblur;
/**
* Indicate if the overView height is resized automatically when the
* device is rotated (ie when the height of the interface change)
* Default value: YES
*/
@property (atomic) BOOL flexibleOverviewHeight;
/**
* Set the value of the blur radius.
* Default value: 20.0
*/
@property (nonatomic) CGFloat blurRadius;
```
And also an initialiser which takes in input a scrolling type which are essentially the 2 kinds of scrolling you see in the previous examples:
```objective-c
- (instancetype)initWithMainImage:(UIImage *)image tableScrollingType:(MGSpotyViewTableScrollingType)scrollingType;
```
