# MTImageMapView
An UIImageView subclass to select a complex polygon map out of many
Extremely useful for handling touches on, for example, Europe map, or an eye of owl
## Screen Shots
 
## Features
- Handling multiple maps on an image1
- Multiple MTImageMapView on a single view
- Support Interface Builder, or progmatical initiation
- Batch mapping2
- Completion block for notifying the end of mapping3
- Delegate to provide selected map index
- Single public class and protocol to implement
- Debug mode to superimpose maps on an image
1. There is no limit but you need to be reasonable. In this example, I put around 50.
2. Mapping takes place in background and prevents UI animation from stuttering.
3. At the end, mapping function notifies on main thread.
## Support
- XCode 4.4 or higher required
- Works on iOS 4.3 ~ iOS 6.0 ARC/MRC (tested on devices)
- Starting from iOS 6.0, DispatchObjects are Object-C objects, meaning when you are to go with ARC, DispatchObjects are also managed by ARC.
♠ You can read more detail at [Does ARC support dispatch queues?](http://stackoverflow.com/questions/8618632/does-arc-support-dispatch-queues).
♦ This paricular issue is solved with OS_OBJECT_USE_OBJC flag. You can read more in detail at [OMG, GCD+ARC](http://www.cocoanetics.com/2013/01/omg-gcdarc/).
## Implementation
1. Use tools like [Gimp](http://www.gimp.org/) and generate a image map.
2. Copy only coordinate pairs of the map (e.g. "123,242,452,242,142,322") in NSString type.
3. Put the strings in an NSArray.
4. Instantiate MTImageMapView and implement MTImageMapDelegate procotol.
5. pass the array to the map view.
(You can use .plist to pass a map batch to a MTImageMapView.)
```objective-c
MTImageMapView *viewImageMap =\
[[MTImageMapView alloc]
initWithImage:
[UIImage imageNamed:@"sample_image.png"]
];
[viewImageMap setDelegate:self];
[self.view addSubview:viewImageMap];
NSArray *arrStates = \
[NSArray arrayWithObjects:
@"542,94,568,94,568,111,542,111"
@"555,150,574,150,574,161,555,161"
@"535,149,551,149,551,159,535,159"
,nil];
[viewImageMap
setMapping:arrStates
doneBlock:^(MTImageMapView *imageMapView) {
NSLog(@"Mapping complete!");
}];
```
```objective-c
-(void)imageMapView:(MTImageMapView *)inImageMapView
didSelectMapArea:(NSUInteger)inIndexSelected
areaCentrePoint:(CGPoint)point
{
[[[[UIAlertView alloc]
initWithTitle:@"*** State Name ***"
message:[stateNames objectAtIndex:inIndexSelected]
delegate:nil
cancelButtonTitle:@"Ok"
otherButtonTitles:nil]
autorelease] show];
}
```
### LIMITS
- Delegate only receives the index of a map
- Coordinates must be provided in pairs
- At least 3 pairs of coordinates must be presented
- No "rect", "circle" type map is supported. "Polygon" only at this time being
