I am trying to read plist which contains array
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>key1</key>
<string>value1</string>
<key>key2</key>
<string>value2</string>
<key>keyarray1</key>
<array>
<string>keyitem1</string>
<string>keyitem2</string>
</array>
</dict>
</plist>
when i try to read valueForKey:@"keyarray1", I get null value. I tried to read as a string and array nut no use.
My Code
NSDictionary * values=[[NSDictionary alloc] initWithContentsOfFile:@"values.plist"];
NSArray *arrayValues=[[NSArray alloc] initWithArray:[values valueForKey:@"keyarray1"]];
First of all Check your plist looks like:
Now write following lines where you are accessing your plist
Objective-C:
NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Values" ofType:@"plist"]];
NSArray *array = [dictionary objectForKey:@"keyarray1"];
NSLog(@"dictionary = %@ \narray = %@", dictionary, array);
Here is the complete screen shot (with log output) of my work window:
Swift:
let dictionary = NSDictionary(contentsOfFile: Bundle.main.pathForResource("Values", ofType: "plist")!);
let array = dictionary?["arrayKey"] as! NSArray
print("dictionary=", dictionary, "\narray =", array)
I know this question is too old and I'll just like to add more information for those people encounter this recently.
In my case I created a plist as Array(plist default is Dictionary with key "Root").
then the xml looks like this:
On my view controller I initialize directly the Array instead of initializing the Dictionary then get object for key "Root":
Note: I only wanted to add this info since I only see initializing the Dictionary then get object for keys. Hope it will help you guys.
Where is the plist stored? Is it in the app bundle? If so, you probably want to use [[NSBundle mainBundle] pathForResource:@"values" ofType:@"plist"]
to get the path, instead of hardcoding @"values.plist"
.
After you have the path down correctly, you can then get the array from the dictionary without any problems, with something like [values objectForKey:@"keyarray"]
.
Final note: there is a difference between objectForKey:
and valueForKey:
. You're currently using valueForkey:
which is part of NSKeyValueCoding
, a protocol that NSDictionary happens to conform to. You should use objectForKey:
(or syntactic sugar accessors, ie dictionary[@"key"]
) instead, as they are the proper ways of accessing a value from a dictionary.
Can you try following code?
NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"values" ofType:@"plist"];
NSDictionary * values=[[NSDictionary alloc] initWithContentsOfFile:plistPath];
NSArray *arrayValues=[[NSArray alloc] initWithArray:[values valueForKey:@"keyarray1"]];
NSLog(@"arrayValues = %@",arrayValues);
I got following output in log:-
arrayValues = (
keyitem1,
keyitem2
)
Swift 4
As in Swift 4 you can use codable & PropertyListDecoder
func setData() {
// location of plist file
if let settingsURL = Bundle.main.path(forResource: "JsonPlist", ofType: "plist") {
do {
var settings: MySettings?
let data = try Data(contentsOf: URL(fileURLWithPath: settingsURL))
let decoder = PropertyListDecoder()
settings = try decoder.decode(MySettings.self, from: data)
print("array is \(settings?.keyarray1 ?? [""])")//prints ["keyitem1", "keyitem2"]
} catch {
print(error)
}
}
}
struct MySettings: Codable {
var keyarray1: [String]?
init(from decoder: Decoder) throws {
let values = try decoder.container(keyedBy: CodingKeys.self)
keyarray1 = try values.decodeIfPresent([String].self, forKey: .keyarray1)
}
}

Try this
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *finalPath = [path stringByAppendingPathComponent:@"values.plist"];
NSMutableDictionary *dict =[NSMutableDictionary dictionaryWithContentsOfFile:finalPath];
NSArray *arr =[dict valueForKey:@"keyarray1"];
NSLog(@"%@",arr);
