    <p>This is sort of a follow-up to this issue: <a href="https://stackoverflow.com/questions/5631095/becomefirstresponder-slows-down-app">becomeFirstResponder slows down app</a></p> <p>I'm experiencing the same problem as that poster, i.e. calling becomeFirstResponder seems to slow down my app (it hangs for maybe 1-2s). However, whereas they were calling it in conjunction with displaying an alert, I am simply trying to unhide a hidden view and have it appear with a certain field as the first responder. Something like:</p> <pre><code>[self.dialogView setHidden:NO]; [self.dialogText becomeFirstResponder]; </code></pre> <p>The dialogView has a hierarchy that contains dialogText (the UITextField I'm trying to set as first responder) and some other items.</p> <p>This slowness is <em>only</em> exhibited the first time this code is executed, i.e. the first time we try to open this dialog. On subsequent attempts, there is no obvious slowness (I assume this is because dialogText is already first responder at that point - I haven't used resignFirstResponder anywhere?).</p> <p>Edit: here's some additional code for context, not sure it will really shed any more light though. Note I'm now animating the unhiding of this dialog view, however the behaviour is no different. I have also since moved the becomeFirstResponder call into the completion block (not reflected in the code here) so that at least the appearance of the dialog isn't delayed, however there is still a delay between the dialog appearing and the keyboard appearing. </p> <pre><code>- (IBAction)showEditDialog:(id)sender { [UIView animateWithDuration:0.3f animations:^() { self.maskView.alpha = 0.8; self.editDialogView.alpha = 1.0; } completion:^(BOOL finished) { if (finished) { } }]; [self.editDialogText becomeFirstResponder]; } </code></pre>

    3. COBasis on your code, i can say after completion of your animation it will show keyboard, comment your animation code and then try. And let me know it, is still taking to much time for keyboard?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
