i create a view based application , in this project i want read data from .plist file.
how it is possible,
Pleas help me ?
NSString *path = [[NSBundle mainBundle] pathForResource:#"plistfilename" ofType:#"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#", path]];
NSString *body = [dict objectForKey:#"Keyname"];
with the use of this anyone can read data from plist file.
If you are sure the .plist file is a dictionary at root level,
return [NSDictionary dictionaryWithContentsOfFile:#"path/to/your.plist"];
otherwise,
NSData* plist_data = [NSData dataWithContentsOfFile:#"path/to/your.plist"];
return [NSPropertyListSerialization propertyListFromData:plist_data mutabilityOption:NSPropertyListImmutable format:NULL errorDescription:NULL];

I have a plist and I copy the plist to my xcode project but it seems like the file is not in bundle:
NSDictionary *dict = [[NSBundle mainBundle] infoDictionary];
nslog (#"dict %#",dict);
but the file plist file is not showing. Question, how can I add the file to project in a way to see in the bundle? also any of you knows how can I modify the plist and save the changes?
I'll really appreciated your help
P.S. I'm using Xcode 5.
You can create a plist file in your bundle and modify its contents as:
NSString *bundlePath = [[NSBundle mainBundle]bundlePath]; //Path of your bundle
NSString *path = [bundlePath stringByAppendingPathComponent:#"MyPlist.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSMutableDictionary *data;
if ([fileManager fileExistsAtPath: path])
{
data = [[NSMutableDictionary alloc] initWithContentsOfFile: path]; // if file exist at path initialise your dictionary with its data
}
else
{
// If the file doesn’t exist, create an empty dictionary
data = [[NSMutableDictionary alloc] init];
}
//To insert the data into the plist
int value = 5;
[data setObject:[NSNumber numberWithInt:value] forKey:#"value"];
[data writeToFile: path atomically:YES];
[data release];
//To retrieve the data from the plist
NSMutableDictionary *savedData = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
int savedValue;
savedValue = [[savedData objectForKey:#"value"] intValue];
NSLog(#"%i",savedValue);
infoDictionary will return Info.plist file.
You should use pathForResource:ofType: method of NSBundle class.
NSString *commonDictionaryPath;
if (commonDictionaryPath = [[NSBundle mainBundle] pathForResource:#"CommonDictionary" ofType:#"plist"]) {
theDictionary = [[NSDictionary alloc] initWithContentsOfFile:commonDictionaryPath];
}
How can I add plist to bundle
Drag your plist to "Copy Bundle Resources" phase of your build target
modify the plist
Copy the plist to your app's Documents folder and modify it there.
this should work
NSString*pListDictPath = [[NSBundle mainBundle] pathForResource:#"yourPlistName" ofType:#"plist" inDirectory:#"YourDirectory"];
if()
{
NSDictionary *theDictionary = [[NSDictionary alloc] initWithContentsOfFile:pListDictPath ];
}

Working with data in iOS Apps (What to choose? NSData, CoreData, sqlite, PList, NSUserDefaults)

Closed 9 years ago.
I've been struggling with this for ages now and I really need some good help here. :)
I have an app where I'm parsing a quite big JSON into appdelegate's didFinishLaunchingWithOptions.
My Model Objects are:
Tab:
NSString *title
NSMutableArray *categories
Category:
NSString *title
NSMutableArray *items
Item
NSString *title
NSString *description
UIImage *image
I need to save the data locally, cause the parsing takes about 15 seconds every time my app starts. I'm using the SBJSON framework.
Here's my code for parsing:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"json_template" ofType:#"json"];
NSString *contents = [NSString stringWithContentsOfFile: filePath encoding: NSUTF8StringEncoding error: nil];
SBJsonParser *jsonParser = [[SBJsonParser alloc] init];
NSMutableDictionary *json = [jsonParser objectWithString: contents];
tabs = [[NSMutableArray alloc] init];
jsonParser = nil;
for (NSString *tab in json)
{
Tab *tabObj = [[Tab alloc] init];
tabObj.title = tab;
NSDictionary *categoryDict = [[json valueForKey: tabObj.title] objectAtIndex: 0];
for (NSString *key in categoryDict)
{
Category *catObj = [[Category alloc] init];
catObj.name = key;
NSArray *items = [categoryDict objectForKey:key];
for (NSDictionary *dict in items)
{
Item *item = [[Item alloc] init];
item.title = [dict objectForKey: #"title"];
item.desc = [dict objectForKey: #"description"];
item.url = [dict objectForKey: #"url"];
if([dict objectForKey: #"image"] != [NSNull null])
{
NSURL *imgUrl = [NSURL URLWithString: [dict objectForKey: #"image"]];
NSData *imageData = [NSData dataWithContentsOfURL: imgUrl];
item.image = [UIImage imageWithData: imageData];
}
else
{
UIImage *image = [UIImage imageNamed: #"standard.png"];
item.image = image;
}
[catObj.items addObject: item];
}
[tabObj.categories addObject: catObj];
}
[tabs addObject: tabObj];
}
What is the best way of doing this? Using Core Data or NSFileManager?
If you have som code example too it will make me very happy.
This is the last thing i need to fix before the app is ready for app store and it just kills me! I can't solve this problem.
If you are working on iOS then you save a file to the Documents folder. On Mac OS X it would be in the Application Support folder. Since you are on iOS, read this answer for how to access the Documents folder.
All of the objects that you want to store should implement NSCoding. The above variables already do. Should you want to store the tabs, categories and items directly they would need to implement NSCoding. Then all you need is to serialize them to a file. When opening you app you can look for this file and get your objects back without parsing.
The code should look something like this (untested and error checking is ommited for brevity):
- (void) saveStateToDocumentNamed:(NSString*)docName
{
NSError *error;
NSFileManager *fileMan = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docPath = [paths[0] stringByAppendingPathComponent:docName];
if ([fileMan fileExistsAtPath:docPath])
[fileMan removeItemAtPath:docPath error:&error];
// Create the dictionary with all the stuff you want to store locally
NSDictionary *state = #{ ... };
// There are many ways to write the state to a file. This is the simplest
// but lacks error checking and recovery options.
[NSKeyedArchiver archiveRootObject:state toFile:docPath];
}
- (NSDictionary*) stateFromDocumentNamed:(NSString*)docName
{
NSError *error;
NSFileManager *fileMan = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docPath = [paths[0] stringByAppendingPathComponent:docName];
if ([fileMan fileExistsAtPath:docPath])
return [NSKeyedUnarchiver unarchiveObjectWithFile:docPath];
return nil;
}
Hi I am trying to make bookmarks for my browser.
Title of Page, Url of Page, any Comments related to page.
I tried to save it in plist, but unsuccessful. Can anyone can help me to save these thing to plist and retrive in table view. So, when user tap on title it will open url in UIWebView.
Here is the code I have tried, so far:
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"bookmarks.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath: path])
{
NSString *bundle = [[NSBundle mainBundle] pathForResource:#"bookmarks" ofType:#"plist"];
[fileManager copyItemAtPath:bundle toPath: path error:&error]; //6
}
NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
NSString *writeUrl = #"Page URL One";
NSString *writeTitle = #"Page Title One";
NSString *writeComment = #"Page comments";
[data setObject:[NSString stringWithString:writeUrl] forKey:#"url"];
[data setObject:[NSString stringWithString:writeTitle] forKey:#"title"];
[data setObject:[NSString stringWithString:writeComment] forKey:#"comment"];
[data writeToFile: path atomically:YES];
NSMutableDictionary *savedUrl = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
NSString *value;
value = [[savedUrl objectForKey:#"url"] stringValue];
NSLog(#"%#", value);
UPDATE: I successfully saved and retrieved data to and from plist. Issue is comming in this line
value = [[savedUrl objectForKey:#"url"] stringValue];
By removing stringValue solve the problem.
value = [savedUrl objectForKey:#"url"];
Now My second issue. I make three items named url, title, comment, types String in plist file.
How can i store different urls. Like
name website: inforains
url: inforains.com
title: Info Rains
comment: good website articles
name website: hitechnology
url: hitechnology.com
title: Hitechnology
comment: hmmm
ans soo on..
how can I store data like this.. so all name website will show on tableview and when user click on anyone, data related to that website will show. I hope i clear my question.
To store multiple records as three items named url, title, comment, types String in plist file
change types from string to dictionary and store data in each dictionary individually for key as 1,2,3 ...
OR
Use three mutable array for each url,title and comment and add object at index 0 at the time of saving it.
and access them when required as nsmutable array.
Change this line
value = [[savedStock objectForKey:#"url"] stringValue];
to
value = [savedUrl objectForKey:#"url"];
because you are saving NSString in dictionary... not NSNumber.
Second issue:
//create mutable array to save all objects
NSMutableArray *objectsArray = [data objectForKey:#"objectsArray"];
if(!objectsArray) {
objectsArray = [[NSMutableArray alloc] init];
}
//create and add dictionary into array
NSDictionary *dictionary = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"url1", #"title1", #"comment2",nil] forKeys:[NSArray arrayWithObjects:#"url", #"title", #"comment",nil]];
[objectsArray addObject:dictionary];
[data setObject:objectsArray forKey:#"objectsArray"];
[data writeToFile: path atomically:YES];
// to read data
NSMutableDictionary *savedUrl = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
NSMutableArray *objectsArraySAved = [savedUrl objectForKey:#"objectsArray"];
for (NSMutableDictionary *dic in objectsArraySAved) {
NSLog(#"URL %#", [dic valueForKey:#"url"]);
}
Are you sure [data writeToFile: path atomically:YES]; works? It returns a BOOL, you should check it.
Are you sure savedURL != nil?
For your new problem, you should put all your dictionaries in a mutable array.
NSMutableArray *bookmarkArray = [[NSMutableArray alloc]init];
[bookmarkArray addObject:data];
I understand I can for instance write a value to a .plist file as such
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"stored" ofType:#"plist"];
NSString *comment = #"this is a comment";
[comment writeToFile:filePath atomically:YES];
But If i had for say an Array inside my .plist (gameArray) and I'd like to white comment into a particular index of my array i.e. gameArray[4] ; how would I do this ?
allow me to clarify
I have a plist: stored.plist
inside my plist there is an array gameArray
i would like to update specific indexes of gameArray inside the plist
is this possible ?
You cannot update and save data in application's main bundle instead you have to do in document directory or other directory like this:
NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *plistFilePath = [documentsDirectory stringByAppendingPathComponent:#"stored.plist"];
if([[NSFileManager defaultManager] fileExistsAtPAth:plistFilePath])
{//already exits
NSMutableArray *data = [NSMutableArray arrayWithContentsOfFile:plistFilePath];
//update your array here
NSString *comment = #"this is a comment";
[data replaceObjectAtIndex:4 withObject:comment];
//write file here
[data writeToFile:plistFilePath atomically:YES];
}
else{ //firstly take content from plist and then write file document directory
NSString *plistPath = [[NSBundle mainBundle] pathForResource:#"stored" ofType:#"plist"];
NSMutableArray *data = [NSMutableArray arrayWithContentsOfFile:plistPath];
//update your array here
NSString *comment = #"this is a comment";
[data replaceObjectAtIndex:4 withObject:comment];
//write file here
[data writeToFile:plistFilePath atomically:YES];
}
Assuming the contents of 'stored.plist' is an array, you need to instantiate a mutable array from the path:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"stored" ofType:#"plist"];
NSMutableArray *array = [NSMutableArray arrayWithContentsOfFile:filePath];
NSString *comment = #"this is a comment";
// inserting a new object:
[array insertObject:comment atIndex:4];
// replacing an existing object:
// classic obj-c syntax
[array replaceObjectAtIndex:4 withObject:4];
// obj-c literal syntax:
array[4] = comment;
// Cannot save to plist inside your document bundle.
// Save a copy inside ~/Library/Application Support
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSApplicationSupportDirectory inDomains:NSUserDomainMask] objectAtIndex:0];
NSURL *arrayURL = [documentsURL URLByAppendingPathComponent:[filePath lastPathComponent]];
[array writeToURL:arrayURL atomically:NO];
I'm creating a Mac app and I want to localize my Labels. I thought a .strings file would be a better choice. But I have trouble reading .strings file in Objective-C. I'm looking for a simpler method.
This is my .string file content:
"LABEL_001" = "Start MyApp";
"LABEL_002" = "Stop MyApp";
"LABEL_003" = "My AppFolder";
...
I have already looked at http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/LoadingResources/Strings/Strings.html.
This is my code:
NSBundle *bundle = [NSBundle mainBundle];
NSString *strFilePath = [[NSBundle mainBundle] pathForResource:#"Labels" ofType:#"strings"];
NSString *tt =NSLocalizedStringFromTableInBundle(#"LABEL_001",strFilePath,bundle, nil);
NSLog(#"STRING ::: %#",tt);
But the string tt gives "LABEL_001", I want "Start MyApp"
What am I doing wrong?
One. You have to name your file Localizable.strings in the <LANGUAGENAME>.lproj directory in the app bundle.
Two. Use the NSLocalizedString macro:
NSString *loc = NSLocalizedString(#"LABEL_001", nil);
Three. If nothing works, you can initialize an NSDictionary using a strings file, as a strings file is a special type of plist:
NSString *fname = [[NSBundle mainBundle] pathForResource:#"whatever" ofType:#"strings"];
NSDictionary *d = [NSDictionary dictionaryWithContentsOfFile:fname];
NSString *loc = [d objectForKey:#"LABEL_001"];
NSString *path = [[NSBundle mainBundle] pathForResource:#"Labels" ofType:#"strings"];
NSData *plistData = [NSData dataWithContentsOfFile:path];
NSString *error; NSPropertyListFormat format;
NSDictionary *dictionary = [NSPropertyListSerialization propertyListFromData:plistData
mutabilityOption:NSPropertyListImmutable
format:&format
errorDescription:&error];
NSString *stringname = [dictionary objectForKey:#"LABEL_001"];
I think it will be helpful to you.
Here the your code
NSBundle *bundle = [NSBundle mainBundle];
NSString *strFilePath = [[NSBundle mainBundle] pathForResource:#"Labels" ofType:#"strings"];
NSString *tt =NSLocalizedStringFromTableInBundle(#"LABEL_001",strFilePath,bundle, nil);
NSLog(#"STRING ::: %#",tt);
The problem here is the 2nd Param "strFilePath", change it to #"Labels" so the above code would become,
NSString *tt =NSLocalizedStringFromTableInBundle(#"LABEL_001",#"Labels",bundle, nil);
For reference, the following line copied from Apple Docs regarding table name,
"When specifying a value for this parameter, include the filename without the .strings extension."
hope this helps.
Simple Code
Just create a method as follows
- (void)localisationStrings
{
NSString* path = [[NSBundle mainBundle] pathForResource:#"localisation" ofType:#"strings"];
NSDictionary *localisationDict = [NSDictionary dictionaryWithContentsOfFile:path];
NSLog(#"\n %#",[localisationDict objectForKey:#"hello"]);
}
