This article is a record to summarized my project to migration from Three20 to Nimbus.

Here is specific step by step to help you porting (migrate) your three20 

Original project is a Facebook photo album which implement base on http://www.raywenderlich.com/1430/three20-tutorial-for-ios-how-to-use-the-three20-photo-viewer

• Add Nimbus in your project

  • Sync code

    • git clone https://github.com/jverkoey/nimbus.git

    • Goes to nimbus path

    • git submodule init

    • git submodule update

  • Include nimbus code in project

    • Core

    • Photos

    • Paging Scroll View

    • Models

    • Overview

  • Include Thirdparty in your code

    • JSONKit

      • remember to add “-fno-objc-arc” on Targets -> Build Phase -> Compiling Phase to disable ARC compiling

    • AFNetworking

  • Add framework

    • libz.dylib

    • MobileCoreServices.framework

    • SystemConfiguration.framework

    • CFNetwork.framework

  • Add those three include in your pch

    #import “NimbusCore.h”

    #import “NimbusPhotos.h”

    #import “NimbusModels.h”

• Remove original Three20 project

  • Remove all Three20 xproj in your framework.

• Replace using to replace TTPhotoViewController to FacebookPhotoAlbumViewController

  • Remove photo.h Photo.m

  • Remove PhotoSet.h PhotoSet.m

  • Remove PhotoViewController.h PhotoViewController.m

  • Drag NimbusPhotos.bundle from src/photos/resources into your project.

  • Add follow file into your project

    • NetworkPhotoAlbumViewController.m NetworkPhotoAlbumViewController.h

    • FacebookPhotoAlbumViewController.m FacebookPhotoAlbumViewController.h

    • CaptionedPhotoView.m CaptionedPhotoView.h

  • Replace PhotoSource related code to follow direct using album ID

    LikePersonAlbum *myEntity = [_fetchResultControllerobjectAtIndexPath:indexPath];

    Class vcClass = [FacebookPhotoAlbumViewControllerclass];

    id initWith = _Facebookalbum_id;

    NSString* title = @”test1”;

    UIViewController* vc = [[vcClass alloc] initWith:initWith];

    vc.title = title;

    [self.navigationControllerpushViewController:vc animated:YES];

• Done, less than 2 hours.

Advantage

• Fast, easy to porting your code to source version control without any setting.

• Compiler time reduce a lot. (Really~~~  a lot)

TODO:

• According to Nimbus “Three20 migration Guide”,  we should use NIToolbarPhotoViewController. Will check it later.

• SDK需要重新安裝與包裝，這次打算放到dropbox可能可以方便下次有富源需求(希望不要)

• iOS Development Certificate的問題

  • 當初我有保留以下檔案

    • AppleWWDRCA.cer

    • CertificateSigningRequest.certSigningRequest

    • Evan_Lin_iPhone4.mobileprovision

    • ios_development.cer

  • 不過還是沒辦法，因為private key 不見了，所以還是得重新申請，參考以下方法

    •  Connect to the apple developer member center then the iOS provisional portal.

    • Revoke my certificate.

    • Create a new certificate by providing a new pair of private and public key.

    • Remove all the previous provisioning profiles and create new ones.

    • Download the new provisioning profiles and install them in XCode by just dragging them to the XCode icon in the dock.

    • refer 

      • http://stackoverflow.com/questions/6769345/xcode-4-valid-signing-identity-not-found-error-on-provisioning-profiles-on-a

• 遇到”A valid provisioning profile matching the application’s Identifier could not be found”

  • 雖然certificate都安裝好了～還是有可能遇到問題

  • 這時候解法是 xcode -> windows -> Orgnizer 然後 editor->refresh from developer portal 

    • refer: http://forum.geego.com/forums/modules/newbb/viewtopic.php?topic_id=623&forum=17

  • 之後要到xcode設定把 target 從iOS device 改道 iPhone

    • refer:  http://stackoverflow.com/questions/16155613/a-valid-provisioning-profile-matching-the-applications-identifier-could-not-be

• 重開xcode 或是重新 clean -> build 就可以

最近也不知道是不是有3C瘟疫
每個周邊的3C商品都開始壞掉
從我的PS3玩到壞掉之後～接下來出現問題竟然是我去年買的Mac Air 2012年中版
(搭配IVB的版本)

依照以下的方式來準備排除方法
排除方法 http://ios.niufangjian.cn/post/3fadb_12debe
最後發現都不行，於是我不得不重新format —> 殘念

重灌好之後，由於有dropbox，evernote還有最重要的Chrome的幫助下，其實重新復原很快的

接下來會希望把所有跟xcode設定還有SDK有關全部放入dropbox之後也方便（也有version control)

最近我的80G胖PS3 玩遊戲玩一下子就會出現逼逼逼後閃紅燈當機
一開始只要修復硬碟後就可以繼續玩
後來只要一進入光碟遊戲就會逼逼逼閃紅燈當機

爬過ptt 跟 01 發現似乎是沒有退路的方法
所以也開始在網路上找新的主機
但是就在備份遊戲資料的時候
我發現其實只要是玩硬碟裡面遊戲
就完全沒有問題～ 但是一玩光碟片遊戲馬上出問題
後來加入PS+ 順便備份存檔跟下載幾個遊戲來確認

雖然沒有問題～不過大家還是建議我說～很有可能會發生一樣的問題

思考過後

我決定買新的PS3 250G （巴哈有綁送戰神一片)~

原因如下：

1. 比較省電 根據Wiki PS3 spec 平均用電是 130W -> 70W
2. 新製程比較不擔心有問題（官方保固一年)
3. 有些東西可以賣來分攤成本

7880 (PS3 250G+戰神)

• 1250 (全新搖桿)
• 250 (HDMI)
• 700 (戰神如果賣二手)

• 500 (原主機殺肉價）

  5180

雖然比起維修2500 貴上一倍～但是想到可以玩的高枕無憂
還可以增加容量從 80G -> 250G

好期待新的主機….

在自學iOS程式的途中，總算需要一些server上的資料了，但是其實也只是要讀一些資料罷了 在需求相當的簡單之下，也曾經去尋找過CSV甚至是找個地方把資料寫成JSON硬讀 不過由於要能方便的修改，所以似乎使用Google Drive上面的Spreadsheet是最簡單最方便的方式

主要參考文章如下：

•  iOS中NSJSONSerialization解析JSON数据暨google地理信息处理案例

  • 主要是看如何處理iOS5中使用基本的NSJSONSerialization來處理JSON 的資料

• JSON data from google spreadsheet

  • 主要是看如何把Google Drive裡面的資料分享出來並且變成JSON

流程如下：

• 建立一個Google Spreadsheet

• 選擇[Publish to web]

• 勾選[Automatically republish when changes are made]

• 會得到一個url～比如說是https://docs.google.com/spreadsheet/pub?key=0An1-zUNFyMVLdEFEdVV3N2h1SUJOdTdKQXBfbGpNTGc&output=html

  • 其中重要的是 key=XXX 後面的資料

• 將你的位置改成  https://spreadsheets.google.com/feeds/list/XXXXXX1/public/values?alt=json  XXX換成你的key

• 這樣就會得到一串JSON

• 接下來就是程式碼的部份

主要程式都是參考 iOS中NSJSONSerialization解析JSON数据暨google地理信息处理案例

-(void)parseJson
{
//The URL of JSON service
//NSString *_urlString = @"http://maps.googleapis.com/maps/api/geocode/json?address=nanjing&sensor=true";
NSString *_urlString = @"https://spreadsheets.google.com/feeds/list/0Artq5Bi16cQedE5mU21kdkJBWUtPU01XbS1uNW5JbEE/1/public/values?alt=json";
NSString *_dataString = [[NSString alloc] initWithData:[_urlString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES] encoding:NSASCIIStringEncoding];

//_dataString=[NSString stringWithUTF8String:[_urlString UTF8String]];

NSURL *_url = [NSURL URLWithString:_dataString];
NSMutableURLRequest *_request = [NSMutableURLRequest requestWithURL:_url];
[_request setValue:@"accept" forHTTPHeaderField:@"application/json"];
[NSURLConnection sendAsynchronousRequest:_request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse* response, NSData* data, NSError* error) {
//block define statment
NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;

int responseStatusCode = [httpResponse statusCode];
NSLog(@"response status code is %d",responseStatusCode);

NSError *_errorJson = nil;

NSDictionary *resultsDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];

if (_errorJson != nil)
{
NSLog(@"Error %@", [_errorJson localizedDescription]);
}
NSDictionary *resultDicFeed = [resultsDic objectForKey:@"feed"];
NSArray *resultsArryEntry= [resultDicFeed objectForKey:@"entry"];
for (NSDictionary * resultDetailDicAll in resultsArryEntry)
{
NSDictionary *resultsDicID=[resultDetailDicAll objectForKey:@"gsx$id"];
NSString * dataID=[resultsDicID objectForKey:@"$t"];

NSDictionary *resultsDicName=[resultDetailDicAll objectForKey:@"gsx$name"];
NSString * dataName=[resultsDicName objectForKey:@"$t"];

NSDictionary *resultsDicDesc=[resultDetailDicAll objectForKey:@"gsx$description"];
NSString * dataDesc=[resultsDicDesc objectForKey:@"$t"];
}

}];
}

如果你有其他欄位名稱～記得把欄位gsx$id gsx$name  gsx$description 改成你的欄位值….
