以编程方式从NSCachesDirectory删除文件 [英] Delete files from NSCachesDirectory programmatically

问题描述

如果我在我的应用程序中以编程方式下载 NSCachesDirectory 中的文件，是否也可以通过编程方式删除文件？

If I downloaded files in NSCachesDirectory programmatically in my app, is it also possible to delete the files programmatically?

推荐答案

NSArray *myPathList = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *mainPath    = [myPathList  objectAtIndex:0];

mainPath = [mainPath stringByAppendingPathComponent:DirectoryName];

这里 mainPath 是文件的完整路径。

Here mainPath is Full Path of File.

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
BOOL fileExists = [fileManager fileExistsAtPath:mainPath];

if (fileExists)
{
     BOOL success = [fileManager removeItemAtPath:mainPath error:&error];
     if (!success) NSLog(@"Error: %@", [error localizedDescription]);

}
