I use CLGeocoder to Geocode a list of address so that certain kinds information can be reflected to theuser in a UITableView. 然而,所有<代码>CLGeocoder的地理编码和逆向地理编码方法均作为参数,在地缘编码要求完整的情况下,由方案其余部分同步操作的代码块:
- (void)geocodeAddressString:(NSString *)addressString
completionHandler:(CLGeocodeCompletionHandler)completionHandler
是否有办法迫使该守则以同步方式运行(即迫使该方案等待地理编码要求,以完成并等待由手提人处理,然后移至<>。
