【问题描述】:
当我添加这一行时我得到了:
locMan = [[CLLocationManager alloc] init];
对于我的 .m 文件中的 viewDidLoad 方法,我遇到了一些我以前从未见过的错误。以下是错误:
我一生都无法弄清楚为什么添加该行会导致问题。如果有人能提供一些启示,我将不胜感激。
我有这个头文件:
#import <UIKit/UIKit.h>
#import "CoreLocation/CoreLocation.h"
@interface RobotWarsViewController : UIViewController
<CLLocationManagerDelegate> {
CLLocationManager *locMan;
// Current Location View
IBOutlet UIView *currentLocationView;
IBOutlet UILabel *currentLocationLabel;
}
@property (assign, nonatomic) UIView *currentLocationView;
@property (assign, nonatomic) UILabel *currentLocationLabel;
@property (assign, nonatomic) CLLocationManager *locMan;
- (IBAction)dropEMP:(id)sender;
- (IBAction)armEMP:(id)sender;
@end
还有这个 .m 文件:
#import "RobotWarsViewController.h"
@implementation RobotWarsViewController
@synthesize locMan;
@synthesize currentLocationView;
@synthesize currentLocationLabel;
- (void)viewDidLoad {
[super viewDidLoad];
locMan = [[CLLocationManager alloc] init];
// locMan.delegate = self;
}
- (IBAction)dropEMP:(id)sender{
NSLog(@"Boo");
}
- (IBAction)armEMP:(id)sender{
NSLog(@"boo");
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation {
NSLog(@"location update");
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
[currentLocationView release];
[currentLocationLabel release];
}
@end
