iOS如何判断应用是否开启摄像头权限

AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];

typedef NS_ENUM(NSInteger, AVAuthorizationStatus) {

AVAuthorizationStatusNotDetermined = 0, //点击允许访问时调用 //用户明确许可与否，媒体需要捕获，但用户尚未授予或拒绝许可。

AVAuthorizationStatusRestricted,

AVAuthorizationStatusDenied, //不允许

AVAuthorizationStatusAuthorized //允许访问

} NS_AVAILABLE_IOS(7_0);

麦克风权限检测：

//检测麦克风功能是否打开

[[AVAudioSessionsharedInstance]requestRecordPermission:^(BOOL granted) {

if (!granted)

{

[ViewUtilalertViewWithString:NSLocalizedString(@"麦克风功能未开启",nil)];

}

else

{

[selfrecord:sender];

}

}];

相册权限检测：需要

#import <AssetsLibrary/AssetsLibrary.h> //导入此类和AssetsLibrary.framework框架

int author = [ALAssetsLibrary authorizationStatus];

NSLog(@"author type:%d",author);

if(author == ALAuthorizationStatusRestricted || author == ALAuthorizationStatusDenied) {

// The user has explicitly denied permission for media capture.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"无法使用相册"

message:@"请在iPhone的\"设置-隐私-照片\"中允许访问照片。"

delegate:self

cancelButtonTitle:@"确定"

otherButtonTitles:nil];

[alert show];

[alert release];

return;
