ios - UITextView crashes

Question

On iOS6 this cod works (myTextView is an instance variable):

myTextView = [[UITextView alloc] initWithFrame:CGRectMake(10, 10, 10, 10)];
myTextView.keyboardType = UIKeyboardTypeDefault;
[self addSubview:myTextView];

And on iOS5 it crashes on line:

[myTextView becomeFirstResponder];

But the strangest thing it that situation is: if i set keyboardType to UIKeyboardTypeEmail - no crashes!

Any ideas?

切勿在主线程以外的线程上调用 UIKit 方法。如果它有效，那只是运气。
