Question

In my application one is mainviewcontroller which is subclass of uiTableviewcontroller holds data from plist when clicked on a particular cell its displays detailviewcontroller(dvc) which is subclass of uiviewcontroller. dvc holds textfield & button .actually when i clicked on button i write textfield’s text on tableviewcell through plist but it is actually write data temporary but i want to write data permanently on tableview what can i do for that .its a navigation based application?

Try this:

Loading the plist to dictionary:

//Get the path to documents directory
NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *plistPath = [rootPath stringByAppendingPathComponent:@"listData.plist"];

//if the file does not exist in documents directory, then load from the bundle.
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) {
   plistPath = [[NSBundle mainBundle] pathForResource:@"listData" ofType:@"plist"];
}

//load plist into NSMutableDictionary.
nes.plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath]; 

Saving dictionary to plist:

//Get the path to documents directory
NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *plistPath = [rootPath stringByAppendingPathComponent:@"listData.plist"];

//Write to documents directory! NOT bundle!!
[nes.plistDict writeToFile:plistPath atomically: YES]; 

Also use:
[nes.plistDict setObject:txtName.text forKey:@”col1″];
Not:
[nes.plistDict setValue:txtName.text forKey:@”col1″];

If this does not help can I see youre cellForRowAtIndexPath in mainviewcontroller?
