#import
@interface MyViewController : UIViewController {
UITextField *textField;
UILabel *label;
NSString *string;
}
@property (nonatomic, retain) IBOutlet UITextField *textField;
@property (nonatomic, retain) IBOutlet UILabel *label;
@property (nonatomic, copy) NSString *string;
- (IBAction)changeGreeting: (id)sender;
- (IBAction)dismissKeyboard: (id)sender;
@end
"
and in your .m-file:
"
#import "MyViewController.h"
@implementation MyViewController
@synthesize textField;
@synthesize label;
@synthesize string;
- (IBAction)changeGreeting: (id)sender {
self.string = textField.text;
NSString *nameString = string;
if ([nameString length] == 0) {
nameString = @"World";
}
NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!",nameString];
label.text = greeting;
[greeting release];
}
-(IBAction)dismissKeyboard: (id)sender {
[sender resignFirstResponder];
}
"
then, connect in the IB's inspector for the textfield the 'did end on exit' option and connect it to the 'dismissKeyboard'.
happy coding...............
