[objective-c]animateWithDuration
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

}
completion:^(BOOL finished){
//アニメーションが終わったとき
[targetView removeFromSuperview];
[targetView release];
targetView=nil;
}
];

[iOS6]UIActivity
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]Safariでinput type="file"
iOS6のSafariからformのinput type=”file”に対応しているので試しました。
Sample
formを作ると左のように表示される。
[ファイルを選択]をタップしたところ
[既存の項目を選択]から画像を選択したところ
[既存の項目を選択]から動画を選択すると、「ビデオを圧縮中…」と出る
動画のサムネイルが表示される
[送信]をタップして遷移したところ
