newRegion.span.longitudeDelta= 0.01;
[_googleView.mapsetRegion:newRegion animated:YES];
}

7. 進制轉化
-(CFStringRef)EncodeUTF8Str:(NSString*)encodeStr{
CFStringRefnonAlphaNumValidChars = CFSTR("![ DISCUZ_CODE_1 ]’()*+,-./:;=?@_~"); 
CFStringRefpreprocessedString = CFURLCreateStringByReplacingPercentEscapesUsingEncoding(kCFAllocatorDefault, (CFStringRef)encodeStr, CFSTR(""), kCFStringEncodingUTF8); 
CFStringRefnewStr =CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,preprocessedString,NULL,nonAlphaNumValidChars,kCFStringEncodingUTF8);
returnnewStr;
}

//轉換成GB2312
-(NSString*)EncodeGB2312Str:(NSString*)encodeStr{ 
CFStringRefnonAlphaNumValidChars = CFSTR("![ DISCUZ_CODE_1 ]’()*+,-./:;=?@_~");

[toform setDateFormat:@"MM-dd HH:mm"];

cell.lblTime.text=[toform stringFromDate:parsed];
[parsed release];
[toform release];




//時間格式轉換

[v removeFromSuperview];
}
} 

13. 讀取本地文件　內容

NSString*filePath=[[NSBundlemainBundle] pathForResource:@"1"ofType:@"txt"];
NSString*str=[[NSStringalloc] initWithContentsOfFile:filePath];
NSLog(@"%@",str);

14. 提取字符串
// 獲得引用的用戶名　和發表時間

}
returnstrResult;
}


15. xml序列化和反序列化 
xml轉換成對象稱爲反序列化
對象轉換成xml 稱爲序列化
16. mac翻..阿..城牆
vbn系統自帶的
17. NSString 初始化
Nsstring *str=nil;//若是不初始化訪問的地址會有錯不肯定
18. 屬性定義
@property(nonatomic,assign)NSInteger nodeCount;
@property(nonatomic,assign) NSInteger unreadMsgSum;
@property(nonatomic,retain)CatalogIDListClass *catalogIDList;

@property(nonatomic,retain)MessageInfoListClass *messageInfoList;
@property(nonatomic,copy)NSString *parentcatalogID;
@property(nonatomic,copy)NSString *Etag_Catalog;
19. 屬性 也要再定義
也要釋放若是用retain 當變量改變是也能夠在改變
20. 每隔一段時間 執行 事件
[NSTimerscheduledTimerWithTimeInterval:0.5target:selfselector:@selector(makeMyProgressBarMoving)userInfo:nilrepeats:NO];
21. 頁面推送方式
[selfpresentModalViewController:picker animated:YES];

22. 命令打開 svn

[array addObject:msg];
}
}

34. 數據庫操做

/**
Method to get smsesfrom group
@param groupID aunique identification of group
@returns a Sms ofNSArray
*/
- (NSArray*)smsesFromGroupID:(NSString*)groupID
{
if(groupID == nil) {
returnnil;
}
[selfresetLastError];

fieldPwd.text=@"sara@gmail.com";
[cell.contentViewaddSubview:fieldPwd];
[fieldPwdrelease];
fieldPwd=nil;


38. tableview下拉不上升
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[table_view setContentOffset:CGPointMake(0, 44) animated:NO];
NSIndexPath *tableSelection = [table_viewindexPathForSelectedRow];
[table_view deselectRowAtIndexPath:tableSelection animated:NO];
}

39. UIActionSheet


if (nil == as_select) { 
as_select= [[UIActionSheet alloc] initWithTitle:nil delegate:selfcancelButtonTitle:@"取消"destructiveButtonTitle:nil otherButtonTitles:@"插入表情",@"轉發",nil];
as_select.actionSheetStyle =UIActionSheetStyleAutomatic; 
}
[as_select showInView:self.view];
40. 設置狀態欄
Status Bar is InitiallyHidden:隱藏上面的狀態欄，在.plist裏添加項

//[gradientLayer setEndPoint:CGPointMake(100, 100)];
[self.layer addSublayer:gradientLaye];
[gradientLaye release];
42. 隱藏Tabbar
CallingViewController*callingVC=[[CallingViewControlleralloc] init];
callingVC.hidesBottomBarWhenPushed=YES;
[self.navigationControllerpushViewController:callingVC animated:YES];
43. 獲得觸摸的位置

48. 得到本地文件內容
NSString*filePath=[[NSBundlemainBundle]pathForResource:@"1"ofType:@"txt"];
NSString*str=[[NSStringalloc]initWithContentsOfFile:filePath];

NSLog(@"str=%@",str);
49. Property list的用法
讀取plist
NSString*errorDesc = nil;

NSPropertyListFormatformat;

NSString*rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];

NSString*plistPath = [rootPath stringByAppendingPathComponent:@"untitled.plist"];

if(![[NSFileManagerdefaultManager] fileExistsAtPath:plistPath]) {

plistPath = [[NSBundlemainBundle] pathForResource:@"untitled"ofType:@"plist"];

}

NSData*plistXML = [[NSFileManagerdefaultManager] contentsAtPath:plistPath];

NSMutableDictionary*mudict = (NSMutableDictionary*)[[NSPropertyListSerializationpropertyListFromData:plistXMLmutabilityOption:NSPropertyListMutableContainersAndLeaves
format:&format
errorDescription:&errorDesc] retain];

NSArray* keysArr = [[[mudict allKeys] sortedArrayUsingSelector:@selector(compare:)] retain];

if(!mudict) {

NSLog(@"Error reading plist: %@, format:%d",errorDesc, format);

}
NSLog(@"keyarr ==%@",[keysArr objectAtIndex:0]);
50. 正則
英文字母數字下劃線是：/^\w+$/;
漢字的是：/^[\u0391-\uFFE5]+$/;
51. 當前時間 計時
timebegin= [NSDatetimeIntervalSinceReferenceDate];


52. 越過tabbar添加view
[self.tabBarController.viewaddSubview:VGlide];

UIImageView* img = [[UIImageViewalloc] initWithImage:[UIImageimageNamed:@"bg.png"]];
img.frame= CGRectOffset( img.frame, 0, 1);
[tabBarCtr.tabBarinsertSubview:img atIndex:0];
[img release];
55. 如何隱藏狀態欄 
[ UIApplication sharedApplication].statusBarHidden = YES;
56. 獲取本地的時區？

[NSTimeZonelocalTimeZone];

57. textview刪除按鈕
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)rangereplacementText:(NSString *)text{
NSLog(@"content is %@, range is %@, text is%@",textView.text,NSStringFromRange(range),text);
if ([text length]==0) {
NSLog(@"NO");
return NO;
}else {
return YES;
}
}
58. textview只現實 聯想字
_inputTxtFeild.hidden=NO;// By Sunny 隱藏原來的
[[_inputTxtFeild.subviewsobjectAtIndex:0] setHidden:YES];
_inputTxtFeild.scrollEnabled=NO;
59. mac svn服務
SmartSVN
60. 斷點調試

imageView.image = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext();

63. uiview 設置圓角 


UIImageView *v=[[UIImageView alloc]initWithFrame:CGRectMake(25, 25, 100, 100)];
    v.image=[UIImage imageNamed:@"face01.png"];
    [[v layer] setBorderWidth:2.0];//畫線的寬度
    [[v layer] setBorderColor:[UIColor blackColor].CGColor];//顏色
    [[v layer]setCornerRadius:15.0];//圓角
    v.backgroundColor=[UIColor redColor];
    
    
    //[v.layer setCornerRadius:8.0];
    [v.layer setMasksToBounds:YES];
    [self.view addSubview:v];
    
    [v release];
64. 建立 NSIndexPath
NSIndexPath*indexpath = [NSIndexPathindexPathForRow:0inSection:<#(NSUInteger)section#>];

65. actionSheet從下方彈出
[actionSheet showFromTabBar:self.tabBarController.tabBar];
[actionSheet showInView:[UIApplicationsharedApplication].keyWindow];


經過secion row 獲得cell
uitableviewcell*cell=(uitableviewcell*)[tableView cellForRowAtIndexPath:indexPath];


66. 經常使用字體
[lblNamesetFont:[UIFontfontWithName:@"Helvetica-Bold"size:18.0]];
[lblContentsetFont:[UIFontfontWithName:@"Helvetica"size:14.0]];


Program received signal: 「EXC_BAD_ACCESS」.:  內存釋放過多

67. 隱藏鍵盤


UIView *v = [[[UIView alloc] initWithFrame:CGRectZero]autorelease];
[begintimesetInputView:v];
68. 父控制器 改變
self.parentViewController.arrAllUnityMsg= nil;

- (void)allOnebox {
OneBoxFolderView* switchFolder = [[OneBoxFolderViewalloc] init];
switchFolder.myParentViewController= self;
switchFolder.hidesBottomBarWhenPushed= YES;
[self.navigationControllerpushViewController:switchFolder animated:YES];
[switchFolder release];
}
OneBoxViewController*_myParentViewController;

self.myParentViewController.arrAllUnityMsg= [[BusinessManagersharedManager].messageSearchManagergetOneBoxMessages];
[self.navigationControllerpopViewControllerAnimated:NO];


69. 枚舉類型 

typedefenum{
ShowAll= 0, //顯示全部的聯繫人
SendMsg= 1, //發送信息
SendEmail= 2//發送郵件

} Sendtype; //在初始化時，須要制定發送的方式，在彈出

Arial 黑體 , 
71. 官方中文版的《iPhone人機界面指南》

72. 從新顯示tabbar
NSMutableArray*list1 = [[NSMutableArrayalloc]init];
[list1 addObjectsFromArray:self.navigationController.viewControllers];
OneBoxViewController*oneboxCtr = [[OneBoxViewControlleralloc] initWithNibName:nilbundle:nil];
//[list1 removeLastObject];
//[list1 removeLastObject];
//[list1 removeLastObject];
[list1 removeAllObjects];
[list1 addObject:oneboxCtr];
self.navigationController.viewControllers= (NSArray*)list1;
