ios - 更改pincolor后无法显示注释标题
<p><p>我用这段代码改变了注解的颜色,但是之后标题和副标题就显示不出来了,我该如何解决这个问题?</p>
<p>代码是:</p>
<pre><code>- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString *defaultPinID = @"LYB";
MKPinAnnotationView *customPinview = (MKPinAnnotationView *);
if ( customPinview == nil ) {
customPinview = [[
initWithAnnotation:from reuseIdentifier:defaultPinID] autorelease];
}
if (])
return nil;
if ([ isEqualToString:@"the first"]) {
customPinview.pinColor = MKPinAnnotationColorGreen;
}
return customPinview;
}
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>在“return customPinview”之前的新行中添加以下代码:</p>
<pre><code>customPinview.canShowCallout = YES;
</code></pre></p>
