高德地图添加之后，怎么没显示？

Question

这是我添加地图的代码，
_scrollMapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, ScreenHeight/1.83, ScreenWidth, ScreenHeight/3)];
_scrollMapView.mapType = MAMapTypeStandard;
_scrollMapView.delegate = self;
_scrollMapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
_scrollMapView.showsUserLocation = YES;
_scrollMapView.showsCompass= NO; // 设置成NO表示关闭指南针；YES表示显示指南针
_scrollMapView.showsScale = NO;//设置成NO表示不显示比例尺；YES表示显示比例尺
_scrollMapView.zoomEnabled = YES;
_scrollMapView.scrollEnabled = YES;//NO表示禁用滑动手势，YES表示开启
[_scrollMapView setZoomLevel:17.5 animated:YES];// 地图的缩放级别的范围是[3-19]
_scrollMapView.userTrackingMode = MAUserTrackingModeNone;// 不跟随用户位置，仅在地图上显示
_scrollMapView.logoCenter = CGPointMake(ScreenWidth - 55, ScreenHeight/1.5);
[self.view addSubview:_scrollMapView];
怎么地图没有显示，设置了高德地图这几个字的显示坐标，也没起作用

可能是你的其他控件的位置和地图重叠了，或者你的frame值计算错误
