我被卡住了:(
在我的应用程序中,每当它获得新位置的更新时我都需要从CLLocationManager更新.我没有使用XIB/NIB文件,我编写的所有内容都是以编程方式完成的.代码:
.h
@interface TestViewController : UIViewController
UILabel* theLabel;
@property (nonatomic, copy) UILabel* theLabel;
@end

.m
...
-(void)loadView{
....
UILabel* theLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0,0.0,320.0,20.0)];
theLabel.text = @"this is some text";
[self.view addSubView:theLabel];
[theLabel release]; // even if this gets moved to the dealloc method, it changes nothing...
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
NSLog(@"Location: %@", [newLocation description]);
// THIS DOES NOTHING TO CHANGE TEXT FOR ME... HELP??
[self.view.theLabel setText:[NSString stringWithFormat: @"Your Location is: %@", [newLocation description]]]; …Run Code Online (Sandbox Code Playgroud)
