嘿,我目前正在开发一个小应用程序,但是我的内存使用率却很高。 的应用得到了约200个地图标注,这些被添加像Swift - 映射注解的更好方法
//Number: 1 Airport: Lukla - Mount Everest
let location1:CLLocationCoordinate2D = CLLocationCoordinate2DMake(AirportLat[1], AirportLong[1])
let info1 = CustomPointAnnotation()
info1.coordinate = location1
info1.title = AirportTitle[1]
info1.imageName = AirportimageName[1]
Map.addAnnotation(info1)
//Number: 2 Airport: Helgoland
let location2:CLLocationCoordinate2D = CLLocationCoordinate2DMake(AirportLat[2], AirportLong[2])
let info2 = CustomPointAnnotation()
info2.coordinate = location2
info2.title = AirportTitle[2]
info2.imageName = AirportimageName[2]
Map.addAnnotation(info2)
//Number: 3 Airport: Aspen
let location3:CLLocationCoordinate2D = CLLocationCoordinate2DMake(AirportLat[3], AirportLong[3])
let info3 = CustomPointAnnotation()
info3.coordinate = location3
info3.title = AirportTitle[3]
info3.imageName = AirportimageName[3]
Map.addAnnotation(info3)
从我,所以我得到了一些阵列,但通过它创建每个注释自己的(但所有的“阵列算了算一个接一个”)我肯定有一个更好的方法来做到这一点,任何人都可以给我一些tipps如何减少这种情况,也许为此使用for/while? :(我没有得到阵列的任何工作
感谢@insane -36 :)该死的容易:) ima idiot :) – 2014-09-25 09:00:23
