有時候想寫一個從相簿挑選照片的程式, 但 xcode 的 simulator 並不支援照相功能 ,

那個 simulator 相簿總是空空的 , 無法從那邊挑選照片, 於是寫了這個小程式 ,

program 功能是從一個 圖片網址 把那張圖抓下來並且存進 simulator 的相簿中, 這個 code 有實作存成功跟存失敗時的 method.

今天並且練習把這個 open source code hosting 在 google code , 可以 download 下來參考.

URL = https://code.google.com/p/monster-oasis-opensource-iphone/downloads/list

google code 也提供 svn checkout 機制 , 怎麼 check out

參考 URL = https://code.google.com/p/monster-oasis-opensource-iphone/source/checkout

不過發現 google code 雖然提供熟悉的 svn 機制 , 但是有兩大缺點:

1. project 必須為 open source , public 的
2. 介面很麻煩

不如, 來看一下 git 怎麼用: https://github.com/plans

以下是 這個 code 的截圖:

首先, 可以這樣定義 ,  定義出有 3 個 section , 在那個 enum Sections array 中, 第一個 item 就讓它的 value = 0 , 那麼最後一個item : NUM_SECTIONS 的 value自然就是這個 array 的 item 數, 就這樣精簡漂亮!!讚嘆! code 寫這樣就非常清楚易懂, 也好 maintain.

再依此定義出 每個 section 的 rows …..

—-

在 numberOfRowsInSection 中, 直接來個 switch(section) 用 case name 的方式 ,直接 return 該 section 有多少 rows 數值回去…, 若無法 mapping 到的 section 就是用 default return 0;

—

在 cellForRowAtIndexPath 中 , 要 show 出該 section 的 該 row 內容, 也是用 switch case mapping 的方式 , 把正確的內容回傳…

—

點選 row 時的處理, 也是同樣的作法…

[上午 10:17:04] _RTN 神奇傑克:  object-c的html parser 這裡有解答 http://stackoverflow.com/questions/405749/parsing-html-on-the-iphone

libxml2.2 comes in the SDK, and libxml/HTMLparser.h claims the following:

    This module implements an HTML 4.0 non-verifying parser with API compatible with the XML parser ones. It should be able to parse "real world" HTML, even if severely broken from a specification point of view.

class  : 大寫開頭

method / instance : 小寫

Property List / SQLite 寫法 sample

類似 printf 的寫法

NSString *debugMsg = [NSString stringWithFormat:@"Process %d", 1];

取亂數

定義:
#define RANDOM_SEED() srandom(time(NULL))
#define RANDOM_INT(__MIN__, __MAX__) ((__MIN__) + random() % ((__MAX__+1) - (__MIN__)))

// --- 這樣用
    NSLog(@"%d" , RANDOM_INT(0,9) );

取 unixtime :

    NSDate *past = [NSDate date];
    NSTimeInterval oldTime = [past timeIntervalSinceDate:[NSDate dateWithNaturalLanguageString:@"01/01/1970"]];
    NSString *unixTime = [[NSString alloc] initWithFormat:@"%0.0f", oldTime];
    NSLog(@"%@" , unixTime);

印出 debug message / popup alert 的寫法:

// ---
-(void) printdebug:(id)msg {
	NSLog(@"%@", msg);
}

// ---
-(void) displayAlertMessage:(id)msg {
	// Display AlertView
	UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"___Alert___" message:msg
                        delegate:self cancelButtonTitle:@"Close" otherButtonTitles: nil];
	[alert show];
	[alert release];
}

Objective-C 奇怪的 null detect!

	if ( (NSNull *)[item objectForKey:@"nick"]==[NSNull null] ) {
		// FOR GUEST DATA
		cell.textLabel.text = @"Guest";
	} else {
		// FOR MEMBER DATA
		cell.textLabel.text = [item objectForKey:@"nick"];
	}

ASYNC network 寫法:

想抓別人的 iphone project 來試玩看看, 在 build 時會有這種 message 的解決方法

Check dependencies
error: There is no SDK with the name or path ‘iphoneos2.2′

重選 “Base SDK for All Configurations” , 如圖:

這隻程式會展現一個地圖, 並以目前定位的座標為中心點, 及一個按鈕,按下按鈕會把座標及UDID傳送到 server , 由 server 端的程式記錄下來, 並且 server 端亂數送出一個水果名回傳給 iPhone client 端, iPhone client 端再把這水果名 show 在 iPhone screen上.

底下是片斷程式碼:

FirstViewController.h :

#import 
#import

#import 

@interface FirstViewController : UIViewController  {
  IBOutlet MKMapView *mapView;
  CLLocationManager *locationManager;
  CLLocation *currentLocation;

}

- (IBAction) updateLocation;

@end

FirstViewController.m :

- (void)viewDidLoad {
  [super viewDidLoad];

  if (locationManager==nil) {
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
  }

  [locationManager startUpdatingLocation];

  [mapView setMapType:MKMapTypeStandard];
}

- (void)locationManager:(CLLocationManager *)manager
  didUpdateToLocation:(CLLocation *)newLocation
       fromLocation:(CLLocation *)oldLocation {

  NSLog(@"Location : %.6f , %.6f", newLocation.coordinate.latitude , newLocation.coordinate.longitude );

  MKCoordinateRegion region = [mapView region];

  region.center = newLocation.coordinate;

  MKCoordinateSpan span;
  span.latitudeDelta = 0.01;
  span.longitudeDelta = 0.01;
  region.span = span;
  [mapView setRegion:region animated:TRUE];

  //
  if ( currentLocation != nil) {
    [currentLocation release];
    currentLocation = nil;
  }
  currentLocation = [newLocation copy];

}

- (IBAction) updateLocation {

  if(currentLocation==nil)
    return;

  UIDevice *device=[[UIDevice alloc] init];

  NSString *URLString=[[NSString alloc] initWithFormat:@"http://z.monster.tw/save_location.php?lat=%.6f&lng=%.6f&id=%@"
             ,currentLocation.coordinate.latitude
             ,currentLocation.coordinate.longitude
             ,device.uniqueIdentifier];

  [device release];

  NSLog(@"%@",URLString);

  // Send Request
  NSURLRequest *request=[NSURLRequest requestWithURL:[NSURL URLWithString:[URLString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]
                       cachePolicy:NSURLRequestReloadIgnoringCacheData
                     timeoutInterval:20.0]; 

  NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
  NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

  NSLog(@"%@",returnString);  

  // Display AlertView
  UIAlertView *alert = [[UIAlertView alloc] initWithTitle:returnString message:@"Thanks!"
                           delegate:self cancelButtonTitle:@"Close" otherButtonTitles: nil];
  [alert show];
  [alert release];  

  [returnString release];
}

intro. xcode / iPhone 開發限制 / 應用軟體架構 / 記憶體管理

first App. – HelloWorld

程式語法 – simple

Interface Builder基本操作

字串與資料結構 / UI Catalog

second App. – Location base App.

upload to real iPhone – use Apple

★ init , copy , retain 要記得 release memory

★ didReceiveMemoryWarning , viewDidUnload 暫時釋放 memmory

★ IBOutlet 引用到的 InterfaceBuilder 元件建議作 release , 但要注意到不要重覆 release
