#Sharing Feature New API iOS 8
- eg. UIAlertController, UIVisualEffectView
we always use UIAlertView and UIActionSheet before iOS 8. But it is not convenient for deal with button event throught delegate method.
Now we can add button event to UIAlertAction, we can use Block by UIAlertAction. then UIAlertController has two style: UIAlertControllerStyleActionSheet, UIAlertControllerStyleAlert.
//Here you set style is actionSheet or Alert
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"This is a message for showing" preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
//if you want to do something what you do
NSLog(@"click done button");
}];
[alertController addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:^{
//do sth
}];
alertStyle
ActionSheetStyle
Apple supplies blurEffect in iOS 8, BlurStyle: UIBlurEffectStyleExtraLight, UIBlurEffectStyleLight, UIBlurEffectStyleDark;
UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:effectStyle];
UIVisualEffectView *effectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
effectView.frame = self.imageView.frame;
self.effectView = effectView;
[self.view addSubview:self.effectView];
if want to use UIVibrancyEffect: Example Code:
UIImage *iconImage = [UIImage imageNamed:@"nie_side_icon_coucher"];
CGRect iconFrame = CGRectMake(0, 0, iconImage.size.width, iconImage.size.height);
UIImageView *iconImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, iconImage.size.width, iconImage.size.height)];
iconImageView.image = iconImage;
UIVibrancyEffect *vibrancyEffect = [UIVibrancyEffect effectForBlurEffect:blurEffect];
UIVisualEffectView *iconEffectView = [[UIVisualEffectView alloc] initWithEffect:vibrancyEffect];
iconEffectView.frame = CGRectMake(150, 200, iconImage.size.width * 4, iconImage.size.height * 2);
iconImageView.frame = CGRectMake(0, 0, iconImage.size.width, iconImage.size.height);
[iconEffectView.contentView addSubview:iconImageView];
iconFrame.origin.y = iconImage.size.height;
iconFrame.size.width = iconImage.size.width * 4;
UILabel *titleLabel = [[UILabel alloc] initWithFrame:iconFrame];
titleLabel.text = @"Blur title";
[iconEffectView.contentView addSubview:titleLabel];
[self.effectView.contentView addSubview:iconEffectView];
