Please help me, I'm in serious trouble if I do not sort this out!
I am trying to save a dictionary to a local file, but inserting a new record
crashes my app and I can not fathom why, here is my code...please let me know
if you see anything im doing wrong..
PS: the random key is purely for testing.
#import "MyTestClass.h"
@implementation MyTestClass
- (id) init
{
self = [super init];
//get path
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
destinationPath = [[paths objectAtIndex:0]
stringByAppendingPathComponent:@"filePath.plist"];
//
dataDict = [NSMutableDictionary
dictionaryWithContentsOfFile:destinationPath];
if(!dataDict){ NSLog(@"No File"); dataDict = [[NSMutableDictionary alloc]
init];} else{[dataDict retain];}
return self;
}
- (void) insertNewRecord:(NSMutableDictionary*)newRecord{
[newRecord retain];
[dataDict setValue: newRecord forKey: [NSString stringWithFormat:@"test%d",
(arc4random() % 1000)] ];
bool didSave = [dataDict writeToFile:destinationPath atomically:YES];
}
//singleton
static MyTestClass *myInstance = NULL;
+ (MyTestClass *)myTestClass
{
@synchronized(self)
{
if (myInstance == NULL)
myInstance = [[self alloc] init];
}
return(myInstance);
}
@end
