我想从我的应用程序文档目录中删除图像。我编写的删除图像的代码是:
-(void)removeImage:(NSString *)fileName
{
fileManager = [NSFileManager defaultManager];
paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
documentsPath = [paths objectAtIndex:0];
filePath = [documentsPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", fileName]];
[fileManager removeItemAtPath:filePath error:NULL];
UIAlertView *removeSuccessFulAlert=[[UIAlertView alloc]initWithTitle:@"Congratulation:" message:@"Successfully removed" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
[removeSuccessFulAlert show];
}
它部分工作。此代码从目录中删除文件,但是当我检查目录中的内容时,它仍然显示图像名称。我想从目录中完全删除该文件。我应该在代码中更改什么才能执行相同的操作?谢谢
我检查了你的代码。它对我有用。使用下面修改后的代码检查您遇到的任何错误
- (void)removeImage:(NSString *)filename
{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [documentsPath stringByAppendingPathComponent:filename];
NSError *error;
BOOL success = [fileManager removeItemAtPath:filePath error:&error];
if (success) {
UIAlertView *removedSuccessFullyAlert = [[UIAlertView alloc] initWithTitle:@"Congratulations:" message:@"Successfully removed" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
[removedSuccessFullyAlert show];
}
else
{
NSLog(@"Could not delete file -:%@ ",[error localizedDescription]);
}
}
