Twitter iPad应用程序背后的机制是什么?我觉得它有分割视图控制器,带动画和手势控制的视图控制器,或者可能有无限滚动的滚动视图.如何为我的应用程序开发相同的UI?
我正在尝试通过AppleScript通过默认邮件客户端发送带样式的文本电子邮件.似乎新版本的OSX无法识别内部的HTML内容.10.11(El Capitan)有没有解决方法?
使用10.10(优胜美地)解决方案工作得非常好.
tell application "Mail"
set theMessage to make new outgoing message with properties {subject:textSubject, visible:false}
tell theMessage
set html content to textBody
repeat with i from 1 to count toNameList
make new to recipient at theMessage with properties {name:item i of toNameList, address:item i of toAddressList}
end repeat
send
end tell
end tell

谢谢.
当我使用NSArray
和NSString
对象记录保留计数时,我的行为不均匀.
请参阅下面的代码,
NSArray *aryTemp = [NSArray arrayWithObjects:@"One",nil];
NSLog(@"Retain Count :%d",[aryTemp retainCount]);
NSArray *aryTemp2 = [[NSArray alloc] initWithObjects:@"One",nil];
NSLog(@"Retain Count :%d",[aryTemp2 retainCount]);
NSString *strTemp = @"One";
NSLog(@"Retain Count :%d",[strTemp retainCount]);
NSString *strTemp2 = [[NSString alloc] initWithString:@"One"];
NSLog(@"Retain Count :%d",[strTemp2 retainCount]);
