ALAuth檢查工作不

Question

我試圖檢查，但我得到了以下錯誤：

Error 1: initializer element is not compile-time constant 
Error 2: Excepted identifier or '(' 

下面的代碼：

#import <UIKit/UIKit.h> 
#import <AssetsLibrary/AssetsLibrary.h> 

//(Error 1) ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus]; 

//(Error 2) if (status != ALAuthorizationStatusAuthorized) { 
    //show alert for asking the user to give permission 

} 

這些代碼是在我的.m文件，我該如何解決這個問題（請附上代碼）？

糟糕，我犯了一個小錯誤。我忘了添加viewdidload

#import <UIKit/UIKit.h> 
#import "BaseViewController.h" 
#import <AssetsLibrary/AssetsLibrary.h> 

@interface ViewController14() 

@end 

@implementation ViewController14 
- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus]; 

    if (status != ALAuthorizationStatusAuthorized) { 
     //show alert for asking the user to give permission 

    } 
} 

@end
