access plist data
i have a plist which goes like this:
<dict>
<key>11231654</key>
<array>
<string>hello</string>
<string>goodbye</string>
</array>
<key>78978976</key>
<array>
<string>开发者_JAVA技巧;ok</string>
<string>cancel</string>
</array>
i've load the plist using this:
NSString *path = [[NSBundle mainBundle] pathForResource:
@"data" ofType:@"plist"];
// Build the array from the plist
NSMutableArray *array3 = [[NSMutableArray alloc] initWithContentsOfFile:path];
how can i access each element of my plist? i want to search for a matching key in the plist and than search with its child. how can i do this? any suggestion?
thks in advance!
Arrays are indexed. If you wanted to access the first object in an NSArray
, you’d do the following:
id someObject = [array objectAtIndex:0];
If you know the object type, you could do it like this:
NSString *myString = [array objectAtIndex:0];
EDIT: You need to use an NSDictionary
for the data that you have—note that it starts with a <dict>
tag, not an <array>
tag (though there are arrays as values).
NSString *path = [[NSBundle mainBundle] pathForResource:
@"data" ofType:@"plist"];
// Build the array from the plist
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
NSArray *value = [dict valueForKey:@"11231654"];
Now you can do whatever you want with your array.
Here is a link to a discussion that provided a very good example of how to access your data and which type of storage schemes would be more beneficial under certain circumstances. @Jeff Kelley's solution is on target, I just thought this question would add an additional resource. Hope this helps!
This is how you need to create plist
Set root to array instead of dictionary , this will give you results in sequence. With below lines of code you can fetch complete plist.
NSString *pathOfPlist = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"];
arrPlistValue = [[NSArray alloc]initWithContentsOfFile:path];
NSLog(@"Plist Value : %@",arrPlistValue);
After that you can fetch any specific content with below code:
NSString *strName = [[arrTempValue objectAtIndex:0] objectForKey:@"name"];
NSString *strImage = [[arrTempValue objectAtIndex:0] objectForKey:@"image"];
int idValue = [[[arrTempValue objectAtIndex:0] objectForKey:@"id"] integerValue];
BOOL isSubCat = [[[arrTempValue objectAtIndex:0] objectForKey:@"isSubCategory"] boolValue];
With this code you can fetch integer , string , boolean from plist.!
