iphone - iOS : cannot delete file

Question

我是 iOS 新手。我有一个问题。

我记录文件的路径，并在 Finder 中验证它。但是 fileExistsAtPath: 返回 NO，这就是我无法删除它的原因。

我需要帮助!!

代码如下:

+ (void)removeImage:(NSString*)imgName {
MyLog(@"%@", [Tool getFileFullPath:imgName]);
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
BOOL fileExists = [fileManager fileExistsAtPath:(NSString *)[Tool getFileFullPath:imgName]];
NSLog(@"Path to file: %@", [Tool getFileFullPath:imgName]);        
NSLog(@"File exists: %d", fileExists);
NSLog(@"Is deletable file at path: %d", [fileManager isDeletableFileAtPath:[Tool getFileFullPath:imgName]]);
if (fileExists) 
{
    BOOL success = [fileManager removeItemAtPath:[Tool getFileFullPath:imgName] error:&error];
    if (!success) NSLog(@"Error: %@", [error localizedDescription]);
}

}

文件路径:/Users/vibolteav/Library/Application Support/iPhone Simulator/5.1/Applications/FD57CA70-14E4-442D-9CA5-DE7A7AD56A93/Documents/img/2053871632

文件存在:0

可删除文件位于路径:1

要从文档目录中删除文件，请使用以下代码:

 -(void)removeOneImage:(NSString*)fileName
{
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:fileName];
    NSLog(@"%@",fullPath);
    [fileManager removeItemAtPath: fullPath error:NULL];
