Here I am adding values to nsmutablearray in the firstviewcontroller. When I click UIButton I want pass this array to another view controller.
AppointmentClass *appObj = [[AppointmentClass alloc]init];
appObj.subject = [key objectForKey:@"Subject"];
appObj.location = [key objectForKey:@"Location"];
appObj.scheduledStart = [key objectForKey:@"ScheduledStart"];
appObj.scheduledEnd = [key objectForKey:@"ScheduledEnd"];
[firstNameArray addObject:appObj];
[appObj release];
appObj=nil;
When I passing firstnamearray value to appointmentdataarray.
secondviewcontroller *appointmentViewObject = [[secondviewcontroller alloc]initWithNibName:@"secondviewcontroller" bundle:nil];
[appointmentViewObject setAppointmentDataArray:firstNameArray];
From the above the appointmentdataarray returning a null value.
[self presentModalViewController:appointmentViewObject animated:YES];
[appointmentViewObject release];
您是否已分配阵列?
NSMutableArray* firstNameArray = [NSMutableArray array];
You can try one thing: in secondviewcontroller.m
add a following method:
-(id) initwithnibName:(NSString*)_nib withArray:(NSMutableArray*)_array{
self = [super initWithNibName:_nib bundle:nil];
if (self) {
self.array =_array;
}
return self;
}
and add -(id) initwithnibName:(NSString*)_nib withArray:(NSMutableArray*)_array;
to secondviewcontroller.h
.
Now replace secondviewcontroller *appointmentViewObject = [[secondviewcontroller alloc]initWithNibName:@"secondviewcontroller" bundle:nil]; [appointmentViewObject setAppointmentDataArray:firstNameArray];
secondviewcontroller *appointmentViewObject = [[secondviewcontroller alloc]initWithNibName:@"secondviewcontroller" bundle:nil]; [appointmentViewObject setAppointmentDataArray:firstNameArray];
with secondviewcontroller *appointmentViewObject = [[secondviewcontroller alloc]initwithnibName:@"secondviewcontroller" withArray:firstNameArray];
Hope this helps.
Try modifying statement:
[appointmentViewObject setAppointmentDataArray:firstNameArray];
With this:
[appointmentViewObject setAppointmentDataArray:[NSArray arrayWithArray:firstNameArray]];
use this:
secondviewcontroller.h file
NSMutableArray* AppointmentDataArray;
@property(nonatomic,retain) NSMutableArray* AppointmentDataArray;
-(void)setMyArray:(NSMutableArray *)arr;
secondviewcontroller.m file
@synthesize AppointmentDataArray;
- (id)initWithNibName:(NSString *)nibNameOrNil
bundle:(NSBundle *)nibBundleOrNil
{
if ((self = [super initWithNibName:nibNameOrNil
bundle:nibBundleOrNil])) {
// Custom initialization.
AppointmentDataArray = [[NSMutableArray alloc] init];
}
return self;
}
-(void)setMyArray:(NSMutableArray *)arr{
AppointmentDataArray=arr;
}
///////When you push
secondviewcontroller *appointmentViewObject = [[secondviewcontroller alloc]initWithNibName:@"secondviewcontroller" bundle:nil];
[appointmentViewObject setMyArray:firstNameArray];
[self presentModalViewController:appointmentViewObject animated:YES];
