先来说说如何自定义大头针以及点击大头针时弹出的泡泡view
一 : 自定义大头针
新建CustomAnnotationView 继承自MAAnnotationView
添加属性
重写- (id)initWithAnnotation:(id)annotation reuseIdentifier:(NSString *)reuseIdentifier
重写- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event 解决泡泡view超出父控件事件响应问题
重写- (void)setSelected:(BOOL)selected animated:(BOOL)animated
二 : 自定义泡泡View
新建自定义气泡类 CustomCalloutView，继承 UIView。
在 CustomCalloutView.h 中定义数据属性，包含：图片、商户名和商户地址。(随便你怎么搞,在这里我就搞了一个xib)
Snip0620_1.png
在上面新建的CustomAnnotationView.h中定义自定义气泡属性
#import "CustomCalloutView.h"
@interface CustomAnnotationView : MAAnnotationView
@property (nonatomic, readonly) CustomCalloutView *calloutView;
@end
重写选中方法- (void)setSelected:(BOOL)selected animated:(BOOL)animated。选中时新建并添加calloutView，传入数据；非选中时删除calloutView。
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
if (self.selected == selected)
{
return;
}
if (selected)
{
if (self.calloutView == nil)
{
/* Construct custom callout. */
self.calloutView = [CustomCalloutView calloutView];
self.calloutView.frame = CGRectMake(0, 0, kCalloutWidth, kCalloutHeight);
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];
}
修改ViewController.m，在MAMapViewDelegate的回调方法mapView:viewForAnnotation中的修改annotationView的类型
#pragma mark - MAMapViewDelegate
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id)annotation
{
if ([annotation isKindOfClass:[MAPointAnnotation class]])
{
static NSString *customReuseIndetifier = @"customReuseIndetifier";
CustomAnnotationView *annotationView = (CustomAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:customReuseIndetifier];
if (annotationView == nil)
{
annotationView = [[CustomAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:customReuseIndetifier];
// must set to NO, so we can show the custom callout view.
annotationView.canShowCallout = NO;
annotationView.draggable = YES;
annotationView.calloutOffset = CGPointMake(0, -5);
}
return annotationView;
}
return nil;
}
用于调整泡泡view显示不全问题
- (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view
{
/* Adjust the map center in order to show the callout view completely. */
if ([view isKindOfClass:[CustomAnnotationView class]]) {
CustomAnnotationView *cusView = (CustomAnnotationView *)view;
CGRect frame = [cusView convertRect:cusView.calloutView.frame toView:self.mapView];
frame = UIEdgeInsetsInsetRect(frame, UIEdgeInsetsMake(kCalloutViewMargin, kCalloutViewMargin, kCalloutViewMargin, kCalloutViewMargin));
if (!CGRectContainsRect(self.mapView.frame, frame))
{
/* Calculate the offset to make the callout view show up. */
CGSize offset = [self offsetToContainRect:frame inRect:self.mapView.frame];
CGPoint theCenter = self.mapView.center;
theCenter = CGPointMake(theCenter.x - offset.width, theCenter.y - offset.height);
CLLocationCoordinate2D coordinate = [self.mapView convertPoint:theCenter toCoordinateFromView:self.mapView];
[self.mapView setCenterCoordinate:coordinate animated:YES];
}
}
}
