IOS-檔案操作合集-待更新

1.判斷Bundle裡面的檔案是否存在

-(BOOL)judgeFileExist:(NSString * )fileName

{

   //擷取檔案路徑

   
NSString *path = [[NSBundle
mainBundle] pathForResource:fileName
ofType:@""];

   
if(path==NULL)

   returnNO;

   returnYES;

}

2.判斷Doucuments　裡面的檔案是否存在

-(BOOL)judgeFileExist:(NSString * )fileName;

{

   NSArray *paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);

   
NSString *documentsDirectory = [paths objectAtIndex:0];

   
NSString * filePath=[documentsDirectory stringByAppendingPathComponent:fileName];

   NSFileManager * fileManager=[NSFileManagerdefaultManager];

   
return [fileManager fileExistsAtPath:filePath];

}

3.得到檔案的路徑

- (NSString *)imageFilePath:(NSString *)fileNname  

{  

　　

　　//NSString *paths = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];

   NSArray *paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
 

   
NSString *documentsDirectory = [paths objectAtIndex:0];  

   
return [documentsDirectory stringByAppendingPathComponent:fileNname];  

}
