我已使用此代码创建了自定义注释。
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
static NSString *const AnnotatioViewReuseID = @"AnnotatioViewReuseID";
// MKAnnotationView
MKPinAnnotationView *annotationView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:AnnotatioViewReuseID];
if (!annotationView) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotatioViewReuseID];
}
if ([annotation isKindOfClass:[FBAnnotationCluster class]]) {
FBAnnotationCluster *cluster = (FBAnnotationCluster *)annotation;
cluster.title = [NSString stringWithFormat:@"%lu", (unsigned long)cluster.annotations.count];
UIView *view = [[UIView alloc]init];
view.backgroundColor = [UIColor colorWithRed:33.0/255.0 green:191.0/255.0 blue:133.0/255.0 alpha:1.0];
UILabel *label = [[UILabel alloc]init];
label.text = cluster.title;
label.textAlignment = NSTextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.textAlignment = NSTextAlignmentCenter;
UIFont *font = [UIFont fontWithName:@"Avenir-Medium" size:14.0];
label.font = font;
label.frame = CGRectMake(0, 0, [self widthOfString:label.text]+20, [self widthOfString:label.text]+20);
view.frame = CGRectMake(0, 0, label.frame.size.width, label.frame.size.width) ;
view.layer.cornerRadius = view.frame.size.height/2;
view.layer.borderColor = [UIColor whiteColor].CGColor;
view.layer.borderWidth = 2.0;
view.clipsToBounds = true;
[view addSubview:label];
for (UIView *view in [annotationView subviews])
{
[view removeFromSuperview];
}
[annotationView addSubview:view];
annotationView.enabled = YES;
annotationView.annotation = annotation;
annotationView.canShowCallout = YES;
annotationView.pinTintColor = [UIColor clearColor];
} else {
annotationView.pinTintColor = [UIColor clearColor];
annotationView.layer.borderColor = [UIColor clearColor].CGColor;
annotationView.layer.borderWidth = 0.0;
FBAnnotation *a = (FBAnnotation*)annotation;
NSLog(@"amount is %f",a.amount);
UIImage *image = [UIImage imageNamed:@"icon-marker-select"];
UIImageView *imgView = [[UIImageView alloc]init];
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = NSNumberFormatterDecimalStyle;
formatter.maximumFractionDigits = 2;
NSString *result = [formatter stringFromNumber:[NSNumber numberWithDouble:a.amount]];
NSString *strData = [NSString stringWithFormat:@"%@%@",a.currency,result];
UIFont *font = [UIFont fontWithName:@"Avenir-Medium" size:14.0];
NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.alignment = NSTextAlignmentCenter;
NSDictionary *attributes = @{
NSFontAttributeName : font,
NSParagraphStyleAttributeName : paragraphStyle,
NSForegroundColorAttributeName : [UIColor whiteColor]
};
CGSize textSize = [strData sizeWithAttributes:attributes];
CGRect textRect = CGRectMake(5, (image.size.height-textSize.height)/2 - 2, textSize.width , textSize.height);
UILabel *textLable = [[UILabel alloc]initWithFrame:textRect];
textLable.textColor = [UIColor whiteColor];
textLable.font = font;
textLable.text = strData;
UIImage *lightSymImg = [UIImage imageNamed:@"icon_lightning"];
UIImageView *lightImage = [[UIImageView alloc]init];
lightImage.image = lightSymImg;
CGRect imgRect = CGRectMake(textRect.origin.x+textRect.size.width, (image.size.height-lightSymImg.size.height)/2 - 2, lightSymImg.size.width,lightSymImg.size.height);
lightImage.frame = imgRect;
imgView.frame = CGRectMake(0, 0, imgRect.size.width + imgRect.origin.x+5, image.size.height);
imgView.image = image;
for (UIView *view in [annotationView subviews])
{
[view removeFromSuperview];
}
annotationView.annotation = annotation;
[annotationView addSubview:imgView];
[annotationView addSubview:textLable];
[annotationView addSubview:lightImage];
annotationView.enabled = YES;
annotationView.canShowCallout = NO;
}
return annotationView;
}
在didSelect方法中,我已编写此代码用于呈现视图控制器
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
NSLog(@"didSelectAnnotationView");
if ([view.annotation isKindOfClass:[FBAnnotationCluster class]]) {
NSLog(@"FBAnnotationCluster select annotation");
}
else{
SpotDetailVC *locDetailVC = [[UIStoryboard storyboardWithName:@"SpotDetail" bundle:nil] instantiateViewControllerWithIdentifier:@"SpotDetailVC"];
[self presentViewController:navController animated:YES completion:nil];
}
}
现在,当我第一次单击注释时,它可以工作但在再次关闭该视图后单击相同的注释它不起作用。
请帮助,我知道这是愚蠢的错误,但我无法配置那个。
