@implementation Myannotationview

-(Instancetype) Initwithannotation: (id<mkannotation>) annotation reuseidentifier: (NSString *) reuseIdentifier {

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

Save parameters-pass over the pin

mypointannotation = annotation;

Create a picture

UIImage *image = [UIImage imagenamed:@ "Pink"];

This method is only suitable for static pictures, not suitable for dynamic and drag dynamic functions, they have conflicting

This way inherits Mkannotationview otherwise no effect

NSData *imagedata = uiimagepngrepresentation (image);

Processing ImageData ratio 5

Image = [UIImage imagewithdata:imagedata scale:5];

Modify the size of the current view

Self.frame = CGRectMake (0, 0, 40, 40);

Set up a picture

Self.image = image;

Set fill mode to fill proportionally

Self.contentmode = Uiviewcontentmodescaletofill;

Uiimageview *imageview = [[Uiimageview alloc] Initwithframe:cgrectmake (-15,-5, 45, 45)];

Imageview.image = image;

[Self addsubview:imageview];

Allow Bubbles to pop up

Self.canshowcallout = YES;

Dragging

self.draggable = YES;

Drop animation

Self.animatesdrop = YES;

UIButton *leftbutton = [UIButton Buttonwithtype:uibuttontypeinfodark];

[LeftButton addtarget:self Action: @selector (LeftButton) forcontrolevents:uicontroleventtouchupinside];

Set left Access view

Self.leftcalloutaccessoryview = LeftButton;

UIButton *rightbutton = [UIButton buttonwithtype:uibuttontypecontactadd];

[Rightbutton addtarget:self Action: @selector (Rightbutton) forcontrolevents:uicontroleventtouchupinside];

Set Right Access view

Self.rightcalloutaccessoryview = Rightbutton;

}

return self;

}

-(void) LeftButton {

NSLog (@ "leftbutton:%@", mypointannotation.title);

}

-(void) Rightbutton {

NSLog (@ "rightbutton:%@", mypointannotation.information);
