关于SpringBoard里获取GPS坐标， 编译通过，回调没来的问题

技能讨论
1

请教一下， 执行代码， 回调没来，是什么情况，，，。在线等。。。

#import <SpringBoard/SpringBoard.h>
#import <CoreLocation/CoreLocation.h>

%hook SpringBoard

@interface SpringBoard()<CLLocationManagerDelegate>

@end

- (void) locationManager: (CLLocationManager *) manager
    didUpdateToLocation: (CLLocation *) newLocation
    fromLocation: (CLLocation *) oldLocation{
	
    NSString *lat = [NSString alloc] initWithFormat:@"%g", 
        newLocation.coordinate.latitude];
		
    
    NSString *lng = [NSString alloc] initWithFormat:@"%g", 
        newLocation.coordinate.longitude];
		
    
    NSString *acc = [NSString alloc] initWithFormat:@"%g", newLocation.horizontalAccuracy]; 
	
    NSString* str = [NSString alloc] initWithFormat:@"%@ %@ %@", lat, lng, acc];
     
	NSLog(@"=================================================>>>> %@", str);
    [acc release];
    [lat release];
    [lng release];
	[str release];
}


-(void)applicationDidFinishLaunching:(id)application 
{
	%orig;
	
	static CLLocationManager* locationManager = [CLLocationManager alloc]init];
	locationManager.delegate = self;
	//[self.locationManager requestAlwaysAuthorization];    //执行会崩溃
	locationManager.desiredAccuracy = kCLLocationAccuracyBest;    	locationManager.distanceFilter = kCLDistanceFilterNone;
	[locationManager startUpdatingLocation];
	
	NSLog(@"========================================================<<<");
	
}

%end

帖子不要沉。。。。。

不能用category的方式给SpringBoard添加函数，原因书里已经提到了。
解决办法很简单，你另写一个自己的类，实现CLLocationManagerDelegate协议，然后把delegate给指定成这个类的对象就可以了

老大啊， 按照你的方法， 为什么不行呢。。。。

#import <SpringBoard/SpringBoard.h>
#import <CoreLocation/CoreLocation.h>

#import <UIKit/UIKit.h>

@interface MyLocationManager : NSObject<CLLocationManagerDelegate>

	@property (nonatomic, retain) CLLocationManager* locationManager;
	
	-(void)start;
	
@end

@implementation MyLocationManager

-(void)start
{
	_locationManager = [CLLocationManager alloc]init];
	_locationManager.delegate = self;
	//[self.locationManager requestAlwaysAuthorization];
	_locationManager.desiredAccuracy = kCLLocationAccuracyBest;    	_locationManager.distanceFilter = 500;
	[_locationManager startUpdatingLocation];
	
	NSLog(@"MyLocationManager ========================================================<<<");
}

- (void) locationManager: (CLLocationManager *) manager
     didUpdateToLocation: (CLLocation *) newLocation
            fromLocation: (CLLocation *) oldLocation{
			
NSLog(@"locationManager ========================================================<<<");
    
    NSString *lat = [NSString alloc] initWithFormat:@"%g",
                     newLocation.coordinate.latitude];
    
    
    NSString *lng = [NSString alloc] initWithFormat:@"%g",
                     newLocation.coordinate.longitude];
    
    
    NSString *acc = [NSString alloc] initWithFormat:@"%g",
                     newLocation.horizontalAccuracy];
    
    NSLog(@"%@ %@ %@\r\n", lat, lng, acc);
}

@end

%hook SpringBoard

-(void)applicationDidFinishLaunching:(id)application 
{
	%orig;
	
	NSLog(@"SpringBoard ===================================== start");
	
	static MyLocationManager* locationManager = [MyLocationManager alloc] init];
	[locationManager start];
}

%end

syslog里有输出吗？

6

其它都有， 就是回调没有输出。。

7

看看的输出下面有没有提示错误之类的信息

老大你看看。。。

看起来像是iOS 8里SpringBoard没有使用CLLocationManager的权限了，你把这个功能放到别的进程里去应该就好了

10

我测试了一下，把这段代码放在MobileMail里面，会报错：

我在隐私设置里给MobileMail赋上获取地理位置的权限，就正常了

11

我用的是IOS7.1 SDK用的是8.0编译的。

12

老大， 如果我真要在Spring Board里获得GPS，怎么办。。。。。。。而且是还是IOS7的机器。。。。

13

hook住检测CoreLocation权限的那个进程，让它不检查SpringBoard

14

locationd 进程，。。。。。。我去好啊。 好蛋疼。。。。。有没有什么资料什么的。。

15

我试了一下，下面的代码在iOS 6和7上可用，8上失效

#import <CoreLocation/CoreLocation.h>

@interface CLLocationManager ()
- (instancetype)initWithEffectiveBundleIdentifier:(NSString *)arg1;
@end

@interface iOSRELocationManager : CLLocationManager <CLLocationManagerDelegate>
@end

@implementation iOSRELocationManager
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
	NSLog(@"iOSRE: %@", locations);
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
	NSLog(@"iOSRE: %@", error);
}
@end

%hook SpringBoard
- (void)applicationDidFinishLaunching:(id)application 
{
	%orig;

	iOSRELocationManager* locationManager = [iOSRELocationManager alloc] initWithEffectiveBundleIdentifier:@"com.apple.Maps"];
	locationManager.delegate = locationManager;
	[locationManager startUpdatingLocation];
}
%end

这段代码的意思，相当于是SpringBoard借用了Maps的定位功能，因此前提是Maps的定位要开启，才能正常工作。
别忘了你说的一天发一个帖子啊！
