Storing small data in IOS using NSUserDefaults

NSUserDefaults
1. Storing Data

// create a standardUserDefaults variable NSUserDefaults * standardUserDefaults = [NSUserDefaults standardUserDefaults];

// saving an NSString [standardUserDefaults setObject:@"mystring" forKey:@"string"];

// saving an NSInteger [standardUserDefaults setInteger:42 forKey:@"integer"];

// saving a Double [standardUserDefaults setDouble:3.1415 forKey:@"double"];

// saving a Float [standardUserDefaults setFloat:3.1415 forKey:@"float"]; // synchronize the settings

[standardUserDefaults synchronize];

2. Retrieving Data

// create a standardUserDefaults variable NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];

// getting an NSString object NSString *myString = [standardUserDefaults stringForKey:@"keyToLookupString"]; // getting an NSInteger object

NSInteger myInt = [standardUserDefaults integerForKey:@"integerKey"];

// getting an Float object

float myFloat = [standardUserDefaults floatForKey:@"floatKey"];
