先來說說如何自定義大頭針以及點(diǎn)擊大頭針時(shí)彈出的泡泡view
一 : 自定義大頭針
- 新建
CustomAnnotationView繼承自MAAnnotationView - 添加屬性
- 重寫
- (id)initWithAnnotation:(id<MAAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier - 重寫
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event解決泡泡view超出父控件事件響應(yīng)問題 - 重寫
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
二 : 自定義泡泡View
- 新建自定義氣泡類
CustomCalloutView，繼承UIView舍哄。 - 在 CustomCalloutView.h 中定義數(shù)據(jù)屬性侥祭，包含：圖片、商戶名和商戶地址豌注。(隨便你怎么搞,在這里我就搞了一個(gè)xib)
Snip20170620_1.png
- 在上面新建的CustomAnnotationView.h中定義自定義氣泡屬性
#import "CustomCalloutView.h"
@interface CustomAnnotationView : MAAnnotationView
@property (nonatomic, readonly) CustomCalloutView *calloutView;
@end
- 重寫選中方法
- (void)setSelected:(BOOL)selected animated:(BOOL)animated。選中時(shí)新建并添加calloutView，傳入數(shù)據(jù)瑰妄；非選中時(shí)刪除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映砖，在MAMapViewDelegate的回調(diào)方法mapView:viewForAnnotation中的修改annotationView的類型
#pragma mark - MAMapViewDelegate
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)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;
}
- 用于調(diào)整泡泡view顯示不全問題
- (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];
}
}
}
