preg_replaceで複数の文字列置換
<?php
$string='ABC DEF GHI JKL MNO ABC DEF GHI JKL';
$pattern=array("/ABC/","/DEF/","/MNO/");
$replace=array('あいう','えおか','ほげ');
$result=preg_replace($pattern, $replace, $string);
echo $result;
?>
結果
あいう えおか GHI JKL ほげ あいう えおか GHI JKL
UIButtonをドラッグする
UIButton*btn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn addTarget:self action:@selector(onTouchDragInside:withEvent:) forControlEvents:UIControlEventTouchDragInside];
[self.view addSubview:btn];
-(void)onTouchDragInside:(UIButton*)btn withEvent:(UIEvent*)event{
UITouch *touch=[[event touchesForView:btn] anyObject];
CGPoint prevPos=[touch previousLocationInView:btn];
CGPoint pos=[touch locationInView:btn];
float dX=pos.x-prevPos.x;
float dY=pos.y-prevPos.y;
btn.center=CGPointMake(btn.center.x+dX,btn.center.y+dY);
}
ドロップシャドウを付ける
#import <QuartzCore/QuartzCore.h>
UIImageView*iv=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"test.png"]]; iv.layer.shadowOpacity=0.4; iv.layer.shadowOffset=CGSizeMake(2.0, 2.0); [self.view addSubview:iv]; //iv.clipsToBounds=YES; これがあるとドロップシャドウが出ない
UIImageの作り方
NSString*fn=@"image.png"; UIImage*image1=[UIImage imageNamed:fn]; UIImage*image2=[UIImage imageWithContentsOfFile:[NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] bundlePath],fn]]; NSURL*url=[NSURL URLWithString:@"http://yourdomain/image.png"]; NSData*data=[NSData dataWithContentsOfURL:url]; UIImage*image3=[UIImage imageWithData:data];
beginAnimationsはiOS4以降非推奨なので、
より便利なanimateWithDurationを使いましょう。
[UIView animateWithDuration:0.3
animations:^{
//アニメーション内容
targetView.frame=CGRectMake(0, 0, 100, 100);
}
completion:^(BOOL finished){
//アニメーションが終わったとき
[targetView removeFromSuperview];
[targetView release];
targetView=nil;
}
];

iOS6から使えるUIActivityを試しました。
UIActivityはこういうやつです。
-(void)startActivity:(int)type{
NSString*text=@"Hello World!! ";
NSArray*actItems=nil;
UIImage*image=nil;
NSURL*url=nil;
UIActivityViewController*actView;
switch (type) {
case 0://text
actItems=[NSArray arrayWithObjects:text, nil];
break;
case 1://text + image
image=_img0.image;
actItems=[NSArray arrayWithObjects:text,image, nil];
break;
case 2://text + url
url=[NSURL URLWithString:_tf0.text];
actItems=[NSArray arrayWithObjects:text,url, nil];
break;
default:
break;
}
actView=[[[UIActivityViewController alloc] initWithActivityItems:actItems applicationActivities:nil] autorelease];
actView.completionHandler = ^(NSString *activityType, BOOL completed){
//投稿した時
NSLog(@" activityType: %@", activityType);
NSLog(@" completed: %i", completed);
if (!completed) {//キャンセル or 失敗
}
};
[self presentViewController:actView animated:YES completion:^{
//出現アニメ終了時
NSLog(@"appear!!");
}];
}
//実行
[self startActivity:1];
上記startActivityメソッドで
type:0
type:1
type:2
type:1でTwitterをタップしたところ
iOS6のSafariからformのinput type=”file”に対応しているので試しました。

xamlファイルをダブルクリックしてデザイナーで開こうとするとこんなこと言われた
Windows Updateしたら直りました。
ELCImagePickerControllerを使ってカメラロールの写真を複数選択
1) LibraryをLinkさせる
・プロジェクトを選択
・TARGETSを選択
・Build Phasesをクリック
・Link Binary With Librariesをクリック
・「+」をクリック
・AssetsLibrary.frameworkを選択して「add」
2)ヘッダファイルでimport
#import "ELCImagePickerController.h" #import "ELCAlbumPickerController.h"
3)実装
