Previously I mentioned a great library providing a large number of block utilities called BlocksKit enhancing many classes within the iOS SDK to utilize blocks.

Here’s a library from Mysterious Trousers called MTControl inspired by JQuery providing an add-on library for many UIControl based objects that allows you to handle events using blocks.

Here’s an example from the readme using the MTControl enhanced UIButton:

UIButton *button = [UIButton buttonWithType:UIButtonTypeContactAdd];

<a href='#' class='small-button smallblue'><span></span></a>;
[_model fetchFromServer:@"http://mysterioustrousers.com" success:^(BOOL success){
[_spinner stop];
}];
}];

Another example showing MTControl working with A UITextField:

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 300, 40)];

[textField editingDidBegin:^(UIEvent *event) {
textField.text = @"";
}];

And here’s a listing of the events provided by MTControl:

touchDown
touchDownRepeat
touchDragInside
touchDragOutside
touchDragEnter
touchDragExit
touchUpInside
touchUpOutside
touchCancel
valueChanged
editingDidBegin
editingChanged
editingDidEnd
editingDidEndOnExit
allTouchEvents
allEditingEvents

Blocks can definitely make things much easier.

Some time ago I mentioned a great library for creating customizable progress indicators called MBProgressHud.

Here’s a user interface control that explains on the HUD concept allowing you to create great looking progress indicators, but also informative modal views, and alert view like pop-ups.

The control uses a block based syntax has great looking animations and images, and an extensive example is included.

Here’s a series of images from the readme showing the control in action:

You can find MBAlertView on Github here.

A nice easy to use UI control for making great looking alerts, and indicators.

A breadcrumb control for iOS. Features:

• Simple API
• Animated transition
