- (void)locationManager:(CLLocationManager *)manager

fromLocation:(CLLocation *)oldLocation
{
NSDateFormatter * formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setDateFormat:@"yyyy-MM-dd HH:mm"];
NSString *latitude = [NSString stringWithFormat:@"%f", newLocation.coordinate.latitude];
NSString *longitude = [NSString stringWithFormat:@"%f", newLocation.coordinate.longitude];
NSString *stringFromDate = [formatter stringFromDate:newLocation.timestamp];
resultsLabel.text = [NSString stringWithFormat:@"(%@) %@ Location %.06f %.06f %@", ([UIApplication sharedApplication].applicationState == UIApplicationStateBackground) ? @"bg" : @"fg", resultsLabel.tag == 0 ? @"gps:" : @"sig" , newLocation.coordinate.latitude, newLocation.coordinate.longitude, [formatter stringFromDate:newLocation.timestamp]];
NSLog(@"%@", resultsLabel.text);
LocationTestAppDelegate * appDelegate = (LocationTestAppDelegate *)[UIApplication sharedApplication].delegate;
[appDelegate log:resultsLabel.text];
}
しかし、私はこれを出力として取得します。
(null)
の上 :
NSLog(@"%@", resultsLabel.text);
誰かが私が間違っていることを知っていますか?
- (id) initWithLabel:(UILabel*)label
{
resultsLabel = label;
return [super init];
}
そして、私の代理人では、ここにresultLabelを設定しました:
- (void) log:(NSString*)msg
{
NSDateFormatter * formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setTimeStyle:NSDateFormatterMediumStyle];
NSString * logMessage = [NSString stringWithFormat:@"%@ %@", [formatter stringFromDate:[NSDate date]], msg];
NSString * fileName = [self locationPath];
FILE * f = fopen([fileName UTF8String], "at");
fprintf(f, "%s\n", [logMessage UTF8String]);
fclose (f);}

GPS機能を削除しました。
新しい場所に適切なNSLogがどのように配置されるかを誰かが知っていますか。経度緯度タイムスタンプ?

ここでresultlabelを設定します:
@interface LocationDelegate : NSObject <CLLocationManagerDelegate>
{
UILabel * resultsLabel;
NSString * _phonenumber;
}
- (id) initWithLabel:(UILabel*)label;
//-(id)initWithDictionary:(NSDictionary *)dict;
//-(id)initWithName:(NSString *)aName;
//-(NSDictionary *)toDictionary;
@property (nonatomic , retain) NSString *phonenumber;
