在iPhone上使用私有API檢查並切換飛行模式

Question

有誰知道如何使用私有API檢查並切換飛行模式？ （不，SCNetworkReachability不夠好，是的，我很高興能使用私有的API，這將在未來可能會破壞）。

您可能會發現這個有趣的鏈接：

檢查出second hit：

// RadiosPreferences.h 

@class <RadiosPreferencesDelegate>; 

@interface RadiosPreferences : NSObject { 
    struct __SCPreferences { } *_prefs; 
    int _applySkipCount; 
    <RadiosPreferencesDelegate> *_delegate; 
    BOOL _isCachedAirplaneModeValid; 
    BOOL _cachedAirplaneMode; 
    BOOL notifyForExternalChangeOnly; 
} 

@property BOOL airplaneMode; 
@property BOOL notifyForExternalChangeOnly; 
@property <RadiosPreferencesDelegate> * delegate; 


- (void)setAirplaneMode:(BOOL)arg1; 
- (id)init; 
- (void)setValue:(void*)arg1 forKey:(id)arg2; 
- (void)dealloc; 
- (void)synchronize; 
- (void)setDelegate:(id)arg1; 
- (id)delegate; 
- (BOOL)airplaneMode; 
- (void*)getValueForKey:(id)arg1; 
- (void)refresh; 
- (void)initializeSCPrefs:(id)arg1; 
- (void)notifyTarget:(unsigned int)arg1; 
- (void)setCallback:(int (*)())arg1 withContext:(struct { int x1; void *x2; int (*x3)(); int (*x4)(); int (*x5)(); }*)arg2; 
- (void)setNotifyForExternalChangeOnly:(BOOL)arg1; 
- (BOOL)notifyForExternalChangeOnly; 

@end 

這裏有一個如何使用這些結果（從GitHub庫的自述）的例子：

NSBundle *b = [NSBundle bundleWithPath:@"/System/Library/PrivateFrameworks/GAIA.framework"]; 
BOOL success = [b load]; 

Class SKTelephonyController = NSClassFromString(@"SKTelephonyController"); 
id tc = [SKTelephonyController sharedInstance]; 

NSLog(@"-- myPhoneNumber: %@", [tc myPhoneNumber]); 
NSLog(@"-- imei: %@", [tc imei]);
