I save data to plist like this:
- (IBAction)save:(id)sender
{
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *plistPath = [documentsPath stringByAppendingPathComponent:#"data.plist"];
NSMutableArray *data = [NSMutableArray arrayWithContentsOfFile:plistPath];
if (nil == data) {
data = [[NSMutableArray alloc] initWithCapacity:0];
}
else {
[data retain];
}
NSMutableDictionary *array = [[NSMutableDictionary alloc]init];
[array setObject:label1.text forKey:#"Test1"];
[array setObject:label2.text forKey:#"Test2"];
[array setObject:label3.text forKey:#"Test3"];
[array setObject:label4.text forKey:#"Test4"];
NSLog(#"%#", array);
[data addObject:array];
[array release];
[data writeToFile:plistPath atomically: TRUE];
[data release];
}
NSLog:
2012-07-01 18:52:19.566 testapp[22651:707] {
Test1 = 40;
Test2 = 102;
Test3 = 153;
Test4 = 255;
}
How can I load saved data to uitableview?

Answer 1

To read it, do this:
NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
You should then be able to read the values for all the keys like this:
NSString *myValue = [plistDict objectForKey:#"someKey"];
edit:
After rereading your code it seems like you might be doing something you don't want to do. Your current plist structure is a top level array that adds a dictionary to itself every time you invoke "save". Is this what you're trying to do? If so, what represents a cell in your table, an index in the array?
If so, then you want to do
// top level array
NSMutableDictionary* plistArray = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
// individual dictionary at one array index (such as indexPath.row in cellForRowAtIndexPath)
NSMutableDictionary *dictionary = [plistArray objectAtIndex:yourIndex];
In any case, the object you have named "array" is actually a dictionary so you should rename it (or change it to be an array if that's what you want).
