Hi All,
In Todays article we will see how we can handle files in Objective C.
The list of the methods used for accessing and manipulating files are listed below. Here you have to replace the FilePath1, FilePath2 and FilePath strings to our required full file paths to get the desired action.
NSFileManager *fileManager = [NSFileManager defaultManager];
//Get documents directory
NSArray *directoryPaths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [directoryPaths objectAtIndex:0];
if ([fileManager fileExistsAtPath:@""]==YES) {
NSLog(@"File exists");
}
Comparing two file contents
if ([fileManager contentsEqualAtPath:@"FilePath1" andPath:@" FilePath2"]) {
NSLog(@"Same content");
}
Check if writable, readable and executable
if ([fileManager isWritableFileAtPath:@"FilePath"]) {
NSLog(@"File isWritable");
}
if ([fileManager isReadableFileAtPath:@"FilePath"]) {
NSLog(@"File isReadable");
}
if ( [fileManager isExecutableFileAtPath:@"FilePath"]){
NSLog(@"File is Executable");
}
Move file
if([fileManager moveItemAtPath:@"FilePath1" toPath:@"FilePath2" error:NULL]){
NSLog(@"File Moved successfully");
}
Copy file
if ([fileManager copyItemAtPath:@"FilePath1" toPath:@"FilePath2" error:NULL]) {
NSLog(@"File Copied successfully");
}
Remove file
if ([fileManager removeItemAtPath:@"FilePath" error:NULL]) {
NSLog(@"File Removed successfully");
}
Read file
NSData *data = [fileManager contentsAtPath:@"Path"];
Write file
[fileManager createFileAtPath:@"" contents:data attributes:nil];
