Create a Seat Map Layout

ZSeatSelector

Objective-C & Swift / Create a Seat Map Layout

You need to import ZSeatSelector and ZSeat. Also add the ZSeatSelector Delegate to your Controller:

Obj-C

#import "ZSeatSelector.h"
#import "ZSeat.h"

@interface ViewController : UIViewController <ZSeatSelectorDelegate>{
}

Swift

```swift class ViewController: UIViewController, ZSeatSelectorDelegate { } ```
**Create your map using a NSString.**
Note:
A = Available
U = Unavailable
D = Disabled
_ = Space
/ = Line Break (row)

Obj-C

```obj-c NSString *map = @"AAAAA_DAAAA/" @"UAAAA_DAAAA/" @"UUUUU_DAAAA/" @"UAAAA_AAAAA/" @"AAAAA_AAAAA/"; ```

Swift

```Swift let map2:String = "_DDDDDD_DDDDDD_DDDDDDDD_/" + "_AAAAAA_AAAAAA_DUUUAAAA_/" + "________________________/" + "_AAAAAUUAAAUAAAAUAAAAAAA/" + "_UAAUUUUUUUUUUUUUUUAAAAA/" + "_AAAAAAAAAAAUUUUUUUAAAAA/" + "_AAAAAAAAUAAAAUUUUAAAAAA/" + "_AAAAAUUUAUAUAUAUUUAAAAA/" ```
**Create a ZSeatSelector Object as a UIScrollView**
Set Seat Size
Set Images
Set Seat Price
Finally Set Map

Obj-C

```obj-c ZSeatSelector *seat = [[ZSeatSelector alloc]initWithFrame:CGRectMake(0, 30, self.view.frame.size.width, 160)];

[seat setSeatSize:CGSizeMake(32, 32)];
[seat setAvailableImage:[UIImage imageNamed:@"A"]
    andUnavailableImage:[UIImage imageNamed:@"U"]
       andDisabledImage:[UIImage imageNamed:@"D"]
       andSelectedImage:[UIImage imageNamed:@"S"]];
[seat setSeat_price:30];
[seat setMap:map];
[seat setDelegate:self];

<h6>Swift</h6>
```swift
let seats2 = ZSeatSelector()
        seats2.frame = CGRectMake(0, 250, self.view.frame.size.width, 200)
        seats2.setSeatSize(CGSize(width: 30, height: 30))
        seats2.setAvailableImage(   UIImage(named: "A")!,
            andUnavailableImage:    UIImage(named: "U")!,
            andDisabledImage:       UIImage(named: "D")!,
            andSelectedImage:       UIImage(named: "S")!)
        seats2.setMap(map2)
        seats2.seat_price = 5.0
        seats2.selected_seat_limit = 5
        seats2.seatSelectorDelegate = self
        self.view.addSubview(seats2)

**Seat Limit**
You can now add Seat Limit so that if you only allow to select 3 seats, the last 3 seats the user select are the ones that will be shown, deselecting the previous ones

Obj-C

```obj-c [seat setSelected_seat_limit:3]; ```

Swift

```swift seats2.selected_seat_limit = 5 ```

Add the delegate functions

Obj-C

```obj-c - (void)seatSelected:(ZSeat *)seat{ NSLog(@"Seat at Row:%ld and Column:%ld", (long)seat.row,(long)seat.column); } ``` ```obj-c -(void)getSelectedSeats:(NSMutableArray *)seats{ float total=0; for (int i=0; i<[seats count]; i++) { ZSeat *seat = [seats objectAtIndex:i]; printf("Seat[%ld,%ld]\n",(long)seat.row,(long)seat.column); total += seat.price; } printf("--------- Total: %f\n",total); } ```

Swift

```swift func seatSelected(seat: ZSeat) { print("Seat at row: \(seat.row) and column: \(seat.column)\n") } ```

func getSelectedSeats(seats: NSMutableArray) {
        var total:Float = 0.0;
        for i in 0..<seats.count {
            let seat:ZSeat  = seats.objectAtIndex(i) as! ZSeat
            print("Seat at row: \(seat.row) and column: \(seat.column)\n")
            total += seat.price
        }
        print("----- Total -----\n")
        print("----- \(total) -----\n")
    }
