在我的视图加载中我有两个UILabel,我为两者添加了相同的tapGesture.如果点击一个特定的标签,那么应该执行它的功能.但是我无法这样做？
-(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,当我点击EditProfile标签时,它将转到else块. 如何识别单击哪个标签并相应执行所需操作？ 解决方法
像这样检查：
if(currentLabel == lblEditProfile)
//code here
else
//code here
