Question

我正在文档文件夹中创建目录。它适用于较低版本的ios，即ios 6,7到8.0。

但它在ios 8.1.3中产生了问题。

NSString *folderPath;
NSArray *path = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *library = [path objectAtIndex:0];
folderPath = [library stringByAppendingPathComponent:@"Documents/custom"];

BOOL success = [[NSFileManager defaultManager] createDirectoryAtPath:folderPath withIntermediateDirectories:NO attributes:nil error:nil];

NSLog(@"create %d",success);

对于ios版本8.1.3，创建返回0。

任何人都可以提出正在发生的事情。

错误==

2015-02-02 17：37：10.561 ALLDOX [903：51379]创建错误域= NSCocoaErrorDomain Code = 4＆＃34;操作无法完成。（可可错误4。）＆＃34; UserInfo = 0x1565f500 {NSFilePath = / var / mobile / Containers / Data / Application / 36F75DC4-C5E1-4501-A13D-0B17A3B2663E / Library / Documents / custom，NSUnderlyingError = 0x1565d7b0＆＃34;操作无法完成。没有这样的文件或目录＆＃34;}

我得到了答案

Apple更改了目录路径。

/var/mobile/Containers/Data/Application/36F75DC4-C5E1-4501-A13D-0B17A3B2663E/Library/Documents/custom   //Wrong path in ios 8.1.*

/var/mobile/Containers/Data/Application/36F75DC4-C5E1-4501-A13D-0B17A3B2663E/Documents/custom     //Correct path for ios 8.1.*

获取正确目录的正确代码是

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

BOOL success = [[NSFileManager defaultManager] createDirectoryAtPath:folderPath withIntermediateDirectories:NO attributes:nil error:nil];

NSLog(@"create %d",success);
