設定完cookie即可 session_start();
$context = stream_context_create(array(
'http' => array(
'method' => 'POST',
'header' => "Content-Type: application/json\r\n".
'Cookie: '.session_name().'='.session_id()."\r\n"
)));
session_write_close();

只需要將cookie存在cookieStorage裡即可 - (NSData *)send:(NSHTTPURLResponse**)urlResponse
{
NSError *errorState = nil;
NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:urlResponse error:&errorState];
// process cookie
NSArray *allCookies = [NSHTTPCookie cookiesWithResponseHeaderFields:[*urlResponse allHeaderFields] forURL:[*urlResponse URL]];
if ([allCookies count]) {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:allCookies forURL:[*urlResponse URL] mainDocumentURL:nil];
}
return result;
}

在設計iOS app時，常需要用到一些字型
這時候就可以參考一下font list
但是讓我疑惑的是，下列字體亦可依照 app 需求安裝是要如何安裝。
後來在apple上，發現這個

+ (UIColor*)colorWithColorCode:(NSString*)hex
{
NSString *cString = [[hex stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] uppercaseString];
// String should be 6 or 8 or 10 characters
if ([cString length] < 6) return [UIColor grayColor];
// strip 0X if it appears
if ([cString hasPrefix:@"0X"]) cString = [cString substringFromIndex:2];
if ([cString length] != 6 && [cString length] != 8) return [UIColor grayColor];
// Separate into r, g, b substrings
NSRange range;
range.location = 0;
range.length = 2;
NSString *rString = [cString substringWithRange:range];
range.location = 2;
NSString *gString = [cString substringWithRange:range];
range.location = 4;
NSString *bString = [cString substringWithRange:range];
NSString *aString = @"FF";
range.location = 6;
if ([cString length] == 8)
aString = [cString substringWithRange:range];
// Scan values
unsigned int r, g, b, a;
[[NSScanner scannerWithString:rString] scanHexInt:&r];
[[NSScanner scannerWithString:gString] scanHexInt:&g];
[[NSScanner scannerWithString:bString] scanHexInt:&b];
[[NSScanner scannerWithString:aString] scanHexInt:&a];
return [UIColor colorWithRed:((float) r / 255.0f)
green:((float) g / 255.0f)
blue:((float) b / 255.0f)
alpha:((float) a / 255.0f)];
}

今天突然發現我的元件上有一條白線，
不管是用path或讀圖畫出來的都後。
而且iOS6，還沒事。
google後，才發現是antialias搞。
CGContextSetShouldAntialias(context, NO); 參考

有thread和threading二種方式
參考
threadthreading

一直遇到php連不上MySQL的問題
mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file
後來才發現原來是MySQL換密碼加密的方式，所以只要SET PASSWORD = PASSWORD('your_existing_password')
後來又發現要將SET SESSION old_passwords = 0;才行
詳細內容

UPDATE `tablename` SET `time`=DATE_SUB(`time`, INTERVAL 3 HOUR) WHERE 1

NSArray *words = @[@"list", @"of", @"words", @123, @3.14];
NSDictionary *d = @{ @"key": @"value" };
