how to set cornerRadius for only top-left and top-right corner of a UIView

Here's a method - I'm sure it could be shortened.... :D

-(UIView *)roundCornersOnView:(UIView *)view onTopLeft:(BOOL)tl topRight:(BOOL)tr bottomLeft:(BOOL)bl bottomRight:(BOOL)br radius:(float)radius {

UIRectCorner corner; //holds the corner


//Determine which corner(s) should be changed
if (tl) {
    corner = UIRectCornerTopLeft;
}
if (tr) {
    corner = UIRectCornerTopRight;
}
if (bl) {
    corner = UIRectCornerBottomLeft;
}
if (br) {
    corner = UIRectCornerBottomRight;
}
if (tl && tr) { //top
    corner = UIRectCornerTopRight | UIRectCornerTopLeft;
}
if (bl && br) { //bottom
    corner = UIRectCornerBottomLeft | UIRectCornerBottomRight;
}
if (tl && bl) { //left
    corner = UIRectCornerTopLeft | UIRectCornerBottomLeft;
}
if (tr && br) { //right
    corner = UIRectCornerTopRight | UIRectCornerBottomRight;
}

if (tl & tr & bl & br) {
    corner = UIRectCornerAllCorners; 
}

UIView *roundedView = view;
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:roundedView.bounds byRoundingCorners:corner cornerRadii:CGSizeMake(radius, radius)];
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = roundedView.bounds;
maskLayer.path = maskPath.CGPath;
roundedView.layer.mask = maskLayer;

return roundedView;
}

    UIButton *openInMaps = [UIButton new];

    [openInMaps setFrame:CGRectMake(15, 135, 114, 70)];
    openInMaps = (UIButton *)[self roundCornersOnView:openInMaps onTopLeft:NO topRight:NO bottomLeft:YES bottomRight:NO radius:5.0];

TSMessages

This framework provides an easy to use class to show little notification views on the top of the screen. (à la Tweetbot).

The notification moves from the top of the screen underneath the navigation bar and stays there for a few seconds, depending on the length of the displayed text. To dismiss a notification before the time runs out, the user can swipe it to the top or just tap it.

There are 4 different types already set up for you: Success, Error, Warning, Message (take a look at the screenshots)

It is very easy to add new notification types with a different design. Add the new type to the notificationType enum, add the needed design properties to the configuration file and set the name of the theme (used in the config file and images) in TSMessagesView.m inside the switch case.

Take a look at the Example project to see how to use this library. You have to open the workspace, not the project file, since the Example project uses cocoapods.

iOS-NBUKit: Component For Working With Photos Providing A Camera View, Gallery, Image Filter View, And More

Customizable camera, assets, image editing, gallery, picker and UIKit subclasses.

faceimageview - A UIImageView clone that adjusts image content to show faces.

UIImageView clone with a catch:

FaceImageView automatically scales its image to fill the bounds and keep any faces detected in view. This can be useful if you want to display people-based dynamic content with UIViewContentModeScaleToFill but are having issues with it displaying the wrong part of the image, like the background, or someone's feet.

The class uses the CoreImage face detection APIs available in iOS 5.0 or later. This API works in many clear cases, but is not all that reliable. If no faces are detected in an image, FaceImageView defaults to centering the image, like UIImageView's behavior with UIViewContentModeScaleToFill.

A small demo app is included to try out different images and view sizes.

https://github.com/dingbat/faceimageview

RNBlurModalView

RNBlurModal adds depth to the traditional modal/alert view. Calling the view is incredibly similar to setting up and showing a UIAlertView. You can also setup your own custom views and display them with a blurry background. The goal is to truly draw the user's focus directly to your alert using natural effects. This project works on all iOS devices at all orientations with ARC.

Type the following yum command to install nginx web-server:
# yum install nginx

Step #3: Turn on nginx service

Type the following command:
# chkconfig nginx on

How do I start / stop / restart nginx web-server?

Type the following commands:
# service nginx start
# service nginx stop
# service nginx restart
# service nginx status
# service nginx reload

Step #4: Configuration files

1. Default configuration directory: /etc/nginx/
2. Default SSL and vhost config directory: /etc/nginx/conf.d/
3. Default log file directory: /var/log/nginx/
4. Default document root directory: /usr/share/nginx/html
5. Default configuration file: /etc/nginx/nginx.conf
6. Default server access log file: /var/log/nginx/access.log
7. Default server access log file: /var/log/nginx/error.log

To edit the nginx configuration file, enter:
# vi /etc/nginx/nginx.conf
Set or update worker_processes as follows (this must be set to CPU(s) in your system. Use thelscpu | grep '^CPU(s)' command to list the number of CPUs in the server)

worker_processes  2;

Turn on gzip support:

gzip  on;

Save and close the file. Edit the file /etc/nginx/conf.d/default.conf, enter:
# vi /etc/nginx/conf.d/default.conf

nodejs validator

node-validator is a library of string validation, filtering and sanitization methods.

To install node-validator, use npm:

$ npm install validator

To use the library in the browser, include validator-min.js

Example

var check = require('validator').check,
    sanitize = require('validator').sanitize

//Validate
check('test@email.com').len(6, 64).isEmail();        //Methods are chainable
check('abc').isInt();                                //Throws 'Invalid integer'
check('abc', 'Please enter a number').isInt();       //Throws 'Please enter a number'
check('abcdefghijklmnopzrtsuvqxyz').is(/^[a-z]+$/);

//Sanitize / Filter
var int = sanitize('0123').toInt();                  //123
var bool = sanitize('true').toBoolean();             //true
var str = sanitize(' \t\r hello \n').trim();       //'hello'
var str = sanitize('aaaaaaaaab').ltrim('a');         //'b'
var str = sanitize(large_input_str).xss();
var str = sanitize('&lt;a&gt;').entityDecode();      //'<a>'

Web development

Often it's more desirable to check or automatically sanitize parameters by name (rather than the actual string). See this gist for instructions on binding the library to the request prototype.

If you are using the express.js framework you can use the express-validator middleware to seamlessly integrate node-validator.

Example http://localhost:8080/?zip=12345&foo=1&textarea=large_string

get('/', function (req, res) {
    req.onValidationError(function (msg) {
        //Redirect the user with error 'msg'
    });

    //Validate user input
    req.check('zip', 'Please enter a valid ZIP code').len(4,5).isInt();
    req.check('email', 'Please enter a valid email').len(6,64).isEmail();
    req.checkHeader('referer').contains('localhost');

    //Sanitize user input
    req.sanitize('textarea').xss();
    req.sanitize('foo').toBoolean();

    //etc.
});

xss()                           //Remove common XSS attack vectors from user-supplied HTML
xss(true)                       //Remove common XSS attack vectors from images

Extending the library

When adding to the Validator prototype, use this.str to access the string and this.error(this.msg || default_msg) when the string is invalid

var Validator = require('validator').Validator;
Validator.prototype.contains = function(str) {
    if (!~this.str.indexOf(str)) {
        this.error(this.msg || this.str + ' does not contain ' + str);
    }
    return this; //Allow method chaining
}

When adding to the Filter (sanitize) prototype, use this.str to access the string and this.modify(new_str) to update it

var Filter = require('validator').Filter;
Filter.prototype.removeNumbers = function() {
    this.modify(this.str.replace(/[0-9]+/g, ''));
    return this.str;
}

Error handling

By default, the validation methods throw an exception when a check fails

try {
    check('abc').notNull().isInt()
} catch (e) {
    console.log(e.message); //Invalid integer
}

To set a custom error message, set the second param of check()

try {
    check('abc', 'Please enter a valid integer').notNull().isInt()
} catch (e) {
    console.log(e.message); //Please enter a valid integer
}

To attach a custom error handler, set the error method of the validator instance

var Validator = require('validator').Validator;
var v = new Validator();
v.error = function(msg) {
    console.log('Fail');
}
v.check('abc').isInt(); //'Fail'

You might want to collect errors instead of throwing each time

Validator.prototype.error = function (msg) {
    this._errors.push(msg);
    return this;
}

Validator.prototype.getErrors = function () {
    return this._errors;
}

var validator = new Validator();

validator.check('abc').isEmail();
validator.check('hello').len(10,30);

var errors = validator.getErrors(); // ['Invalid email', 'String is too small']
