Displaying modal view in Objective-C
- by kpower
I'm trying to display Modal View in my app.
I have subclass of UIViewController that has only the "Done" button (UIButton created with IB and linked with XCode).
.h
@interface myModalVC : UIViewController {
UIButton *bDone;
}
@property (nonatomic, retain) IBOutlet UIButton *bDone;
- (IBAction)bDoneTouchDown:(id)sender;
@end
.m
#import "myModalVC.h"
@implementation myModalVC
@synthesize bDone;
- (void)dealloc {
[bDone release];
[super dealloc];
}
- (void)viewDidLoad {
[super viewDidLoad];
}
- (void)viewDidUnload {
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (UIInterfaceOrientationLandscapeLeft == interfaceOrientation
|| UIInterfaceOrientationLandscapeRight == interfaceOrientation);
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (IBAction)bDoneTouchDown:(id)sender {
[self.parentViewController dismissModalViewControllerAnimated:YES];
}
@end
I'm trying to display modal view with this code (from my main view):
myModalVC *temp = [[[myModalVC alloc]
initWithNibName:@"myModalVC" bundle:[NSBundle mainBundle]] autorelease];
[self presentModalViewController:temp animated:YES];
If this code is placed in some method, that responds to button touches - everything is fine. But when I place it to some other method (called during some processes in my app) - modal view is displayed without problems, but when I press (touch) "Done" button, application crashes with "Program received signal: “EXC_BAD_ACCESS”."
What am I doing wrong?
