蘋果AppStore對於私有API的檢測越來越嚴格，下邊給大家提供定位、相機、相簿的許可權處理方法，在這個封裝了一個工具類，感興趣的可以拿走。後續會繼續加入其他許可權，歡迎經常來逛逛。

LPDeviceManger.h

#import <Foundation/Foundation.h>

@interface LPDeviceManager : NSObject

/**
 檢測使用者是否開啟位置許可權
 */
+(BOOL)checkUserLocationAuth;
/**
 檢測使用者是否開啟相機許可權
 */
+(BOOL)checkUserCameraAuth;
/**
 檢測使用者是否開啟相簿許可權
 */
+(BOOL)checkUserPhotoAuth;

@end
