在我的视图加载中，我有两个 UILabel，并且我为两者添加了相同的 tapGesture。如果点击特定标签，则应该执行其功能。但我无法这样做？
-(void)viewDidLoad{
lblEditProfile.userInteractionEnabled = YES;
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClicked:)];
[tapGestureRecognizer setNumberOfTapsRequired:1];
[lblEditProfile addGestureRecognizer:tapGestureRecognizer];
[tapGestureRecognizer release];
lblViewDetails.userInteractionEnabled = YES;
tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClicked:)];
[tapGestureRecognizer setNumberOfTapsRequired:1];
[lblViewDetails addGestureRecognizer:tapGestureRecognizer];
[tapGestureRecognizer release];
}
-(IBAction)labelClicked:(UITapGestureRecognizer*)tapGestureRecognizer
{
currentLabel = (UILabel *)tapGestureRecognizer.view;
NSLog(@"tap %@",tapGestureRecognizer.view);
if(currentLabel.text==@"Edit Profile")
{
UserProfile *userProfile = [[UserProfile alloc] initWithNibName:@"UserProfile" bundle:nil];
userProfile.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:userProfile animated:YES];
[userProfile release];
}
else
{
ViewDetails *viewDetails = [[ViewDetails alloc] initWithNibName:@"UserAppointments" bundle:nil];
viewDetails.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: viewDetails animated:YES];
[viewDetails release];
}
}
但是，当我单击“编辑个人资料”标签时，它会被阻止。
如何识别点击了哪个标签并相应地执行所需的操作？
使用这样的标签格式。哪个会更有效率
-(void)viewDidLoad{
lblEditProfile.userInteractionEnabled = YES;
lblEditProfile.tag = 1;
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClicked:)];
[tapGestureRecognizer setNumberOfTapsRequired:1];
[lblEditProfile addGestureRecognizer:tapGestureRecognizer];
[tapGestureRecognizer release];
lblViewDetails.userInteractionEnabled = YES;
lblViewDetails.tag = 2;
tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClicked:)];
[tapGestureRecognizer setNumberOfTapsRequired:1];
[lblViewDetails addGestureRecognizer:tapGestureRecognizer];
[tapGestureRecognizer release];
}
-(IBAction)labelClicked:(UITapGestureRecognizer*)tapGestureRecognizer
{
currentLabel = (UILabel *)tapGestureRecognizer.view;
NSLog(@"tap %d",tapGestureRecognizer.tag);
if(currentLabel.tag == 1)
{
UserProfile *userProfile = [[UserProfile alloc] initWithNibName:@"UserProfile" bundle:nil];
userProfile.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:userProfile animated:YES];
[userProfile release];
}
else if(currentLabel.tag == 2)
{
ViewDetails *viewDetails = [[ViewDetails alloc] initWithNibName:@"UserAppointments" bundle:nil];
viewDetails.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: viewDetails animated:YES];
[viewDetails release];
}
}
