[IOS 视图布局]--分享样式REComposeViewController

https://github.com/romaonthego/REComposeViewController

REComposeViewController

Replicates functionality of SLComposeViewController introduced in iOS 6.0. You can create composers for any social network out there. REComposeViewController doesn't provide logic for sharing, only its visual part.

Requirements

Xcode 4.5 or higher
Apple LLVM compiler
iOS 5.0 or higher
ARC

Demo

Build and run the 

REComposeViewControllerExample

 project
in Xcode to see 

REComposeViewController

 in
action.

Installation

via
CocoaPods

The recommended approach for installating REComposeViewController is via the CocoaPods package manager, as it provides flexible dependency
management and dead simple installation.

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods
$ pod setup

Edit your Podfile and add REComposeViewController:

$ edit Podfile
platform :ios, '5.0'
pod 'REComposeViewController', '~> 2.0.1'

Install into your Xcode project:

$ pod install

Simple
Install

All you need to do is drop 

REComposeViewController

 files
into your project, and add 

#include "REComposeViewController.h"

 to
the top of classes that will use it.

Example
Usage

REComposeViewController *composeViewController = [[REComposeViewController alloc] init];
composeViewController.title = @"Social Network";
composeViewController.hasAttachment = YES;
composeViewController.attachmentImage = [UIImage imageNamed:@"Flower.jpg"];
composeViewController.text = @"Hi there!";
[composeViewController presentFromRootViewController];

Set completion handler:

composeViewController.completionHandler = ^(REComposeViewController *composeViewController, REComposeResult result) {
[composeViewController dismissViewControllerAnimated:YES completion:nil];

if (result == REComposeResultCancelled) {
NSLog(@"Cancelled");
}

if (result == REComposeResultPosted) {
NSLog(@"Text = %@", composeViewController.text);
}
};

Alternatively, you may want to set your controller to conform to 

REComposeViewControllerDelegate

 protocol
to receive notifications when user cancels / posts.

...
composeViewController.delegate = self;
...

- (void)composeViewController:(REComposeViewController *)composeViewController didFinishWithResult:(REComposeResult)result
{
[composeViewController dismissViewControllerAnimated:YES completion:nil];

if (result == REComposeResultCancelled) {
NSLog(@"Cancelled");
}

if (result == REComposeResultPosted) {
NSLog(@"Text = %@", composeViewController.text);
}
}

Customization

REComposeViewController navigation bar can be customized via UIAppearance.
You use the 

UIAppearance

 protocol to get
the appearance proxy for a class. You customize the appearance of instances of a class by sending appearance modification messages to the class’s appearance proxy.

Example:

[composeViewController.navigationBar setBackgroundImage:[UIImage imageNamed:@"bg"] forBarMetrics:UIBarMetricsDefault];
composeViewController.navigationItem.leftBarButtonItem.tintColor = [UIColor colorWithRed:60/255.0 green:165/255.0 blue:194/255.0 alpha:1];
composeViewController.navigationItem.rightBarButtonItem.tintColor = [UIColor colorWithRed:29/255.0 green:118/255.0 blue:143/255.0 alpha:1];
