“Real” URL encoding in iOS

Sometimes if you wish to encode a whole URL including /,&,: , [NSString stringByAddingPercentEscapes:] fails, to solve this issue, use CFURLCreateStringByAddingPercentEscapes

+ (NSString*)urlEncode: (NSString*) url {
    NSString* encoded = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)url, NULL, (CFStringRef)@"!*'();:@&=+$,/?%#[]",kCFStringEncodingUTF8);
    return [encoded autorelease];
}

Error adding EKEvent on iOS 5

If you try to add an EKEvent with startDate equals to endDate to EKEventStore on iOS5, it will throw an error like “No end date has been set”.
To get rid of this problem, you should add a second to endDate property, something like:

if ([event.endDate isEqualToDate:event.startDate]) {
    event.endDate = [event.startDate dateByAddingTimeInterval:1.0]; // add one second
}
