最近开发集成了百度地图，根据需求，我们需要在用户进入地图时就标注一系列的坐标，且所显示的标注必须全部显示气泡框。需求如此，开始我的思路时这样的：利用百度地图API提供的 [xxx setSelected:YES animated:NO];方法，我想便利所有的BMKPinAnnotationView，然后再全部用此方法显示气泡框，但最后测试发现，没有什么卵用，最后他只会在最后一个标注上显示气泡。
在网上也没找到合适的方法，最后逛贴吧，偶然某位朋友提供的一个思路，即：把标注和气泡做成一体 ，这样等于标注显示了 ，气泡等于也一起显示了， 开始撸代码：
自定义BMKPinAnnotationView：
- (id)initWithAnnotation:(id)annotation reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
if (self) {
_titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.f, 0.f, 60, 60)];
_titleLabel.textColor = [UIColor whiteColor];
_titleLabel.font = [UIFont systemFontOfSize:12];
_titleLabel.textAlignment = NSTextAlignmentCenter;
_titleLabel.numberOfLines = 2;
_titleLabel.backgroundColor = [UIColor colorWithRed:255/255.0 green:87/255.0 blue:138/255.0 alpha:0.9];
UITapGestureRecognizer *labelTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClick)];
// 2. 将点击事件添加到label上
[_titleLabel addGestureRecognizer:labelTapGestureRecognizer];
_titleLabel.userInteractionEnabled = YES; // 可以理解为设置label可被点击
[self addSubview:_titleLabel];
_imageView = [[UIImageView alloc] init];
_imageView.alpha = 0.9;
[self addSubview:_imageView];
_pharmacyLabel = [[UILabel alloc] init];
_pharmacyLabel.textColor = [UIColor whiteColor];
_pharmacyLabel.font = [UIFont systemFontOfSize:14];
_pharmacyLabel.textAlignment = NSTextAlignmentCenter;
_pharmacyLabel.numberOfLines = 0;
[_imageView addSubview:_pharmacyLabel];
}
return self;
}
- (void)layoutSubviews {
[super layoutSubviews];
CGSize imageSize = [self contentSize];
_imageView.frame = CGRectMake(0, 0, imageSize.width + 15,imageSize.height + 15 );
_pharmacyLabel.frame = CGRectMake(5, 5, imageSize.width ,imageSize.height);
}
- (CGSize)contentSize {
CGSize maxSize = CGSizeMake(ScreenSize.width *0.5, MAXFLOAT);
// 计算文字的高度
return [_title boundingRectWithSize:maxSize options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName : [UIFont systemFontOfSize:14]} context:nil].size;
}
- (void)labelClick {
}
- (void)setSize:(NSInteger)size {
_size = size;
_titleLabel.hidden = YES;
_imageView.hidden = NO;
_pharmacyLabel.hidden = NO;
_pharmacyLabel.text = _title;
_imageView.image = [UIImage imageNamed:@"mapPopViewBGICon"];
}
- (void)setTitle:(NSString *)title {
_title = title;
}
- (void)setCluster:(XJCluster *)cluster {
_cluster = cluster;
}
其他的就是添加坐标啥的，没有什么，最后在你的代理方法- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id)annotation 返回你自定义的AnnotationView即可。
效果如下图：
