我正在尝试查找并设置如下所示的位置,但我不断收到错误“Invalid Initializer”
CLLocationCoordinate2D location =[self.mapView addressLocation];
其中addressLocation方法如下所示
-(CLLocationCoordinate2D) addressLocation {
NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv",
[searchBar.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]];
NSError* error;
NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSASCIIStringEncoding error:&error];
NSArray *listItems = [locationString componentsSeparatedByString:@","];
double latitude = 0.0;
double longitude = 0.0;
if([listItems count] >= 4 && [[listItems objectAtIndex:0] isEqualToString:@"200"]) {
latitude = [[listItems objectAtIndex:2] doubleValue];
longitude = [[listItems objectAtIndex:3] doubleValue];
}
else {
//Show error
}
CLLocationCoordinate2D location;
location.latitude = latitude;
location.longitude = longitude;
return location;
}
你能告诉我为什么我得到“无效的初始化程序”错误吗?我已经导入了 corelocation 位置框架,还导入了头文件。所以不确定是什么问题。
