我在我的应用程序中使用ShakingAlertView。
https://github.com/lukestringer90/ShakingAlertView
它在 IOS 6 中完美运行。但是在我更新到 IOS 7 后，它没有动画，并且没有调用不正确处理的块功能。下面给出了摇晃警报视图的初始化代码。
currentPass = [[ShakingAlertView alloc]initWithAlertTitle:@"Enter Current Password" checkForPassword:self.pass
usingHashingTechnique:HashTechniqueMD5
onCorrectPassword:^{
isCurrentPassConfirmed = YES;
[self._accountSource willScrollToTop];
self.password.text = @"";
[self.password becomeFirstResponder];
} onDismissalWithoutPassword:^{
//NSLog(@"hi");
[self showFailedPasswordAlert];
}];
currentPass.alertViewStyle = UIAlertViewStyleSecureTextInput;
[currentPass show];
下面是为摇动效果设置动画的方法。它被正确调用但没有效果。
- (void)animateIncorrectPassword {
// Clear the password field
_passwordField.text = nil;
// Animate the alert to show that the entered string was wrong
// "Shakes" similar to OS X login screen
CGAffineTransform moveRight = CGAffineTransformTranslate(CGAffineTransformIdentity, 20, 0);
CGAffineTransform moveLeft = CGAffineTransformTranslate(CGAffineTransformIdentity, -20, 0);
CGAffineTransform resetTransform = CGAffineTransformTranslate(CGAffineTransformIdentity, 0, 0);
[UIView animateWithDuration:0.1 animations:^{
// Translate left
self.transform = moveLeft;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^{
// Translate right
self.transform = moveRight;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^{
// Translate left
self.transform = moveLeft;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^{
// Translate to origin
self.transform = resetTransform;
}];
}];
}];
}];
}
请帮我。
