iOS dateFromString dosn't work properly

[skunkio]

Hi all,
as per my object i have some problems using dateFromString that seems returns always a NSDate object null or another date different from the date i'm using.
To set a date on a DataPicker i use the code below:

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

NSDate *myDate = [df dateFromString: self.selectedDate];

NSLog(@"data 1 %@", self.selectedDate);
NSLog(@"data 2 %@", myDate);
		
if (myDate) {
        dtpDate.date = myDate;
}

this is the NSLog result

data 1 2010-05-12 21:45:00
data 2 1970-01-01 01:00:00 +0100

If use setDateFormat before create myDate, it's always null

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

[df setDateFormat:@"yyyy-MM-dd hh:mm"];
		
NSDate *myDate = [df dateFromString: self.selectedDate];
		
NSLog(@"data 1 %@", self.selectedDate);
NSLog(@"data 2 %@", myDate);
		
if (myDate) {
	dtpDate.date = myDate;
}

this is the result

data 1 2010-05-12 21:45:00
data 2 (null)

If i use NSlocale

NSDateFormatter *df = [[NSDateFormatter alloc] init];
		
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
[df setLocale:locale];
		
NSDate *myDate = [df dateFromString: self.selectedDate];
		
NSLog(@"data 1 %@", self.selectedDate);
NSLog(@"data 2 %@", myDate);
		
if (myDate) {
	dtpDate.date = myDate;
}

there isn't effect.
myDate is null if use setDateFormat otherwise the date is wrong.
How can i set a DataPicket using a date of mine?


Ciao,

this code works

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

[df setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
		
NSDate *myDate = [df dateFromString: self.selectedDate];
		
NSLog(@"data 1 %@", self.selectedDate);
NSLog(@"data 2 %@", myDate);
		
if (myDate) {
	dtpDate.date = myDate;
}

data 1 2010-05-12 21:45:00
data 2 2010-05-12 21:45:00 +0200
