Objective-C Easy Conversion Methods

-(NSNumber*) convertStringToNumber:(NSString*)stringToConvert

{

    

    NSNumberFormatter *f = [[NSNumberFormatter alloc] init];

    [f setNumberStyle:NSNumberFormatterDecimalStyle];

    NSNumber *myNumber = [f numberFromString:stringToConvert];

    

    return myNumber;

    

}

-(NSDate*) convertStringToDate:(NSString*)stringToConvert

{

    

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

    

    // this is imporant - we set our input date format to match our input string

    // if format doesn't match you'll get nil from your string, so be careful

    

    [dateFormatter setDateFormat:@"dd-MM-yyyy hh:mm:ss"];

    NSDate *dateFromString = [[NSDate alloc] init];

    

    // voila!

    

    dateFromString = [dateFormatter dateFromString:stringToConvert];

    

    return dateFromString;

    

}

-(NSString*) convertDateToString:(NSDate*)dateToConvert

{

    

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

    

    [dateFormatter setDateFormat:@"dd-MM-yyyy"];

    

    NSString *strDate = [dateFormatter stringFromDate:dateToConvert];

    

    return strDate;

    

}

-(NSString*) convertNumberToCurrencyString:(NSNumber*) numberValue

{

    NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];

    

    [formatter setNumberStyle:NSNumberFormatterDecimalStyle];

    

    [formatter setMinimumFractionDigits:2];

    return [formatter stringFromNumber:numberValue];
