iphone - 在 iPhone 中创建一个目录

Question

这有什么问题吗？

#define AUDIO_NOTES_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/myApp/Pictures"]

NSFileManager *NSFm= [NSFileManager defaultManager]; 
BOOL isDir=YES;

if(![NSFm fileExistsAtPath:FILEPATH isDirectory:&isDir])
    if(![NSFm createDirectoryAtPath:FILEPATH attributes:nil])
        NSLog(@"Error: Create folder failed");

Answer 1

createDirectoryAtPath:attributes: 已弃用，您应该使用:

    NSString *dirToCreate = [NSString stringWithFormat:@"%@/newDirectory",[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]];
    NSError *error = nil;
    BOOL isDir;
    if(![fm fileExistsAtPath:dirToCreate isDirectory:&isDir])
        if(![fm createDirectoryAtPath:dirToCreate withIntermediateDirectories:YES attributes:nil error:&error])
            NSLog(@"Error: Create folder failed");
