Custom Pins in IOS maps

1. Inherit the Mkannotationview.

HYAnnotationView.h file:

+ (Instancetype) Annotationviewwithmapview: (Mkmapview *) Mapview;

HYANNOTATIONVIEW.M file:

#import "HYAnnotation.h"//header file for import pin model

@interface Hyannotationview ()

@property (nonatomic, weak) Uiimageview *iconview;

@end

@implementation Hyannotationview

+ (Instancetype) Annotationviewwithmapview: (Mkmapview *) Mapview

{

static NSString *id = @ "Anno";

Hyannotationview *annotationview = (Hyannotationview *) [Mapview Dequeuereusableannotationviewwithidentifier:id];

if (Annotationview = = nil) {

Incoming loops use identities to create a pin control

Annotationview = [[Hmannotationview alloc] Initwithannotation:nil Reuseidentifier:id];

}

return annotationview;

}

-(ID) initwithannotation: (id<mkannotation>) annotation reuseidentifier: (NSString *) reuseidentifier

{

if (self = [super Initwithannotation:annotation Reuseidentifier:reuseidentifier]) {

Show titles and subheadings when you customize a PIN, you must write it if you want to display the title and sub-headings

Self.canshowcallout = YES;

Start customizing your PIN here, and you can create a view

[Self setsubview];

}

return self;

}

Custom Pins

-(void) setsubview{

Self.bounds = CGRectMake (0.f, 0.F, Kwidth, kheight);

UILabel *namelab =[[uilabel Alloc]init];

Namelab.width = 40;

Namelab.height = 30;

NAMELAB.Y = 0;

namelab.x = (self.width-namelab.width) * 0.5;

Namelab.font =iwtextfont16;

Namelab.backgroundcolor =iwtextcolorred;

Namelab.textcolor =[uicolor Whitecolor];

NameLab.layer.cornerRadius = 8.0;

NameLab.layer.borderWidth = 1.0;

NameLab.layer.borderColor =[uicolor Clearcolor]. Cgcolor;

Namelab.clipstobounds = true;//Remove boundary

Namelab.textalignment =nstextalignmentcenter;

[Self Addsubview:namelab];

Self.namelab =namelab;

}

Set properties on a PIN

-(void) Setannotation: (hmannotation *) annotation

{

[Super Setannotation:annotation];

}

When you click on a pin, add a custom view to the PIN (if you want to put TableView you can put TableView in the view)

-(void) setselected: (BOOL) selected animated: (BOOL) animated

{

if (self.selected = = selected) return;

if (selected)

{

if (Self.calloutview = nil)//self.calloutview is the property of the custom view

{

Self.calloutview = [[Zlcustomcalloutview alloc] Initwithframe:cgrectmake (0, 0, Kcalloutwidth, kcalloutheight)];

Self.calloutView.centerX =self.width/2.f+ + self.calloutoffset.x;

Self.calloutView.center = Cgpointmake (Cgrectgetwidth (self.bounds)/2.f + self.calloutoffset.x,

-cgrectgetheight (self.calloutView.bounds)/2.f + Self.calloutoffset.y) ;

}

[Self addSubview:self.calloutView];

}

Else

{

[Self.calloutview Removefromsuperview];

}

[Super setselected:selected animated:animated];

}

-(BOOL) Pointinside: (cgpoint) point withevent: (Uievent *) event

{

BOOL inside = [Super Pointinside:point withevent:event];

if (!inside && self.selected)

{

Inside = [Self.calloutview pointinside:[self convertpoint:point ToView:self.calloutView] withevent:event];

}

return inside;

}

At the time of use:

#pragma mark-mkmapviewdelegate

-(Mkannotationview *) Mapview: (Mkmapview *) Mapview viewforannotation: (hyannotation *) annotation

{

Returning nil will follow the system's default practice

if (![ Annotation Iskindofclass:[hyannotation class]) return nil;

1. Get the Pin control

Hyannotationview *annoview = [Hyannotationview Annotationviewwithmapview:mapview];

2. Transfer model

annoview.annotation = annotation;

return annoview;

}
