Question

My problem is when I read content of plist file in an NSMutableArray always return null

NSString *resourceDocPath = [[NSString alloc] initWithString:[[NSBundle mainBundle]bundlePath]] ;

// Create the new dictionary that will be inserted into the plist.

NSMutableDictionary *nameDictionary = [NSMutableDictionary dictionary];
[nameDictionary setValue:@"walid" forKey:@"id"];
[nameDictionary setValue:@"555 W 1st St" forKey:@"lien"];
NSString *r = [NSString stringWithFormat:@"%@/download.plist", resourceDocPath];
NSLog(@"%@",r);
// Open the plist from the filesystem.
NSMutableArray *plist = [NSMutableArray  arrayWithContentsOfFile:r]; 
 NSLog(@"%@",plist);
if (plist == NULL) 
{
    plist = [NSMutableArray array];
}
[plist addObject:nameDictionary];
 NSLog(@"%@",plist);
[plist writeToFile:r atomically:YES];

when I look in the plist file I found the data that I insert only one

can you help me please?

You’re trying to access the application bundle rather than the documents directory, which can be accessed via NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *sourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Populator"];. The bundle cannot be modified, so the created array is never saved, hence why it is never loaded.
