初始化
//初始化地图
-(void)InitSubViewMapView
{
/*创建地图*/
self.mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, kScreenW, kScreenHeight-IPHONEX_SAFE_BOTTOM_MARGIN)];
self.mapView.delegate=self;
///如果您需要进入地图就显示定位小蓝点，则需要下面两行代码
self.mapView.showsUserLocation = YES;
self.mapView.userTrackingMode = MAUserTrackingModeFollow;
//是否显示指南针
self.mapView.showsCompass=NO;
//设置缩放范围
[self.mapView setZoomLevel:18 animated:YES];
//自定义地图
NSString *path1 = [NSString stringWithFormat:@"%@/style_extra.data", [NSBundle mainBundle].bundlePath];
NSString *path2 = [NSString stringWithFormat:@"%@/style.data", [NSBundle mainBundle].bundlePath];
NSData *data1 = [NSData dataWithContentsOfFile:path1];
NSData *data2 = [NSData dataWithContentsOfFile:path2];
MAMapCustomStyleOptions *options = [[MAMapCustomStyleOptions alloc] init];
options.styleData= data2;
options.styleExtraData= data1;
[self.mapView setCustomMapStyleOptions:options];
[self.mapView setCustomMapStyleEnabled:YES];
[self.view addSubview:self.mapView];
}
不需要用到的时候记得销毁
- (void)viewWillAppear:(BOOL)animated{
[superviewWillAppear:animated];
_mapView.showsUserLocation = YES;
_mapView.delegate=self;
}
-(void)viewWillDisappear:(BOOL)animated
{
[superviewWillDisappear:animated];
_mapView.showsUserLocation = NO;
_mapView.delegate=nil;
}
地图拖动时会出现延迟的现象
方法1：
- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
[self applyMapViewMemoryRelease];
}
- (void)applyMapViewMemoryRelease{
MKMapType _type = _mapView.mapType;
switch(_mapView.mapType) {
case MKMapTypeHybrid:
{
_mapView.mapType = MKMapTypeStandard;
}
break;
case MKMapTypeStandard:
{
_mapView.mapType = MKMapTypeHybrid;
}
break;
default:
break;
}
_mapView.mapType= _type;
}
但这样滑动显示区域时会有闪烁
方法2：
- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
[self.mapView removeFromSuperview];
[self.viewaddSubview:mapView];
}
这样可以有效改善内存暴涨的问题
