Calendar API changing - iphone

Question

http://code.google.com/p/scm-subversion/source/browse/trunk/iPhone/CalendarTest/?r=4#CalendarTest%253Fstate%253Dclosed
I am using the above mentioned Calendar API. In CalendarTestViewController.m class we are getting the date. Now I have declared a global variable nsstring type and I want to use that date into another new class by using global variable. I have tried this a number of times but unable to get the output. If anyone know how can I use the selected date by using Calendar API, then please give me some solution.
Thanks in advance.
CODE
- (void)calendarView:(KLCalendarView *)calendarView tappedTile:(KLTile *)aTile{
NSLog(#"Date Selected is %#",[aTile date]);
str=(NSString *)[aTile date];
}
NSLog(#"str:%#",str);
glbdate1 = (NSString *)[aTile date];
NSLog(#"glbdate1:%#",glbdate1);
}
//I have declared the glbdate1 variable globally in app delegate file and i have made the new class calenderview
//I want to display the date in textfield by using global variable. Here is code in calenderview
-(void)viewWillAppear:(BOOL)animated {
if ([glbdate1 length] != 0)
{
from.text = glbdate1;
}
}

Answer 1

You have to convert the NSDate to NSString as follows,
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-mm-dd HH:mm:ss"];
NSString *dateString=[dateFormatter stringFromDate:date];
Then the same NSString value can be converted to NSDate as,
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-mm-dd HH:mm:ss"];
NSDate *dateFromString=[dateFormatter dateFromString:dateString];

-(BOOL)isDateinEventArray:(NSString*)iDateString{
//NSString *searchText = lblDate.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
for (ToDo *todoObj in appDelegate.todoArray)
{
NSString *date = todoObj.startDate;
[searchArray addObject:date];
}
if ([searchArray count] > 0) {
for (NSString *sTemp in searchArray)
{
NSRange titleResultsRange = [sTemp rangeOfString:iDateString
options:NSCaseInsensitiveSearch];
if (titleResultsRange.length > 0)
[copyListOfItems addObject:sTemp];
}
[searchArray release];
searchArray = nil;
}
if ([copyListOfItems count] > 0) {
return TRUE;
}else{
return FALSE;
}
}

// NSString *stringFromDate =

NSString *stringFromDate = [[NSString alloc]initWithString:[NSString stringWithFormat:#"%02i-%02i-%02i",[aTile.date yearOfCommonEra],

if([self isDateinEventArray:stringFromDate]){
selectedDate = [aTile date];
eventFoundMsg = #"Events are found on this date.";
eventMsgTag = 1;
}else{
eventFoundMsg = #"No events are found on this date.";
eventMsgTag = 0;
}
[stringFromDate release];
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Event Message"
message:eventFoundMsg
delegate:self
cancelButtonTitle:#"Ok"
otherButtonTitles:nil]autorelease];
alert.tag = eventMsgTag;
[alert show];
[aTile flash];
/*

else

}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (eventMsgTag == 1) {
if (buttonIndex == 0)
{
MyToDoView *detailViewController = [[MyToDoView alloc]
initWithNibName:#"MyToDoView" bundle:nil];
detailViewController.searchDate = selectedDate;
NSLog([NSString stringWithFormat:#"%#",detailViewController.searchDate]);
[detailViewController searchDateTableView];
[self.navigationController popViewControllerAnimated:YES];
[detailViewController release];
}
}
}
I hope this can help you....
