我有一个带有图钉的地图视图,当用户选择一个图钉时,它会转到该图钉的详细信息屏幕。我还有一个表格视图,当用户选择一个项目时,它会转到相同类型的详细视图。
这就是问题所在...
从 3.1.3 到 4.1,它似乎工作正常。那就是与引脚匹配的详细视图。但是我有一个用户刚刚升级到 iOS 4.2,并说在 4.1 下它工作得很好,但是在 4.2 中,引脚选择将他带到了不同引脚的细节。但是在表格视图中它仍然可以正常工作。
iOS 4.2 中的 MKMapView 是否有可能改变了 pinID 的选择方式?
加法 - 我已经添加了 viewForAnnotation 和 checkButtonTapped 的相关部分
- (MKPinAnnotationView *)mapView:(MKMapView *)eMapView viewForAnnotation:(id <MKAnnotation>)annotation {
int postTag = 0;
MKPinAnnotationView *pinView = (MKPinAnnotationView *)[eMapView dequeueReusableAnnotationViewWithIdentifier:@"Pin"];
if(pinView == nil) {
pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"Pin"];
pinView.frame = CGRectMake(0, 0, 25, 25);
} else {
pinView.annotation = annotation;
}
// Set up the Right callout
UIButton *myDetailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
myDetailButton.frame = CGRectMake(0, 0, 23, 23);
myDetailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
myDetailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
[myDetailButton addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
// Identify which pin is being selected
if ([[annotation title] isEqualToString:@"Current Location"]) {
postTag = 99999;
} else {
postTag = [annotation getPinID];
}
myDetailButton.tag = postTag;
pinView.rightCalloutAccessoryView = myDetailButton;
pinView.animatesDrop = YES;
// Set to show a callout on the pin
pinView.canShowCallout = YES;
return pinView;
}
// Method to show detail view when the callOut button is selected
- (IBAction) checkButtonTapped: (id) sender {
int nrButtonPressed = ((UIButton *)sender).tag;
if (nrButtonPressed < 99999) {
if (self.showDetailView == nil) {
DetailData *tmpViewController = [[DetailData alloc] initWithNibName:@"Detail" bundle:nil];
self.showDetailView = tmpViewController;
[tmpViewController release];
}
buttonDetail = [[mapView annotations] objectAtIndex:(nrButtonPressed-1)];
NSMutableArray *tmpArray = [NSMutableArray arrayWithObjects: [buttonDetail getDataI], [buttonDetail getDataII], [buttonDetail getDataIII], [buttonDetail getDataIV], [buttonDetail getDataV], nil];
self.showDetailView.eventData = [[NSMutableArray alloc] initWithArray:tmpArray copyItems:YES];
[self.navigationController pushViewController:self.showDetailView animated:YES];
[self.showDetailView.eventData release];
}
}
如您所见,在 checkButtonTapped 中,我记录了选定的引脚,然后从该引脚的注释中收集数据。问题似乎是 nrButtonPressed 现在不正确。但是在 4.1 中编译时很好
