在 macOS 上挂在 NTFS 分区为可写

Write to NTFS support MacOS

1. Get the partition UUID

Connect the external drive to MacOS. It should mount read-only. Start "System Information", clic on Hardware -> Storage, select your drive in the list and copy its UUID.

Another way to get the UUID is to use the diskutil CLI tool:

~$ diskutil list 
~$ diskutil info diskXsY

PHP 获取字符串长度（而非字节数）
<?php
$str = 'Hello，世界！';
preg_match_all('/./us', $str, $match);

将 NSString 字符串转换成 Unicode 编码（形如 \u597d）
+ (NSString *)unicodeStringWithString:(NSString *)string {
NSString *result = [NSString string];
for (int i = 0; i < [string length]; i++) {
result = [result stringByAppendingFormat:@"\\u%04x", [string characterAtIndex:i]];
/*
因为 Unicode 用 16 个二进制位（即 4 个十六进制位）表示字符,对于小于 0x1000 字符要用 0 填充空位,
所以使用 %04x 这个转换符, 使得输出的十六进制占 4 位并用 0 来填充开头的空位.
*/
}
return result;

UITextField 点击 Return 后隐藏键盘
// 首先把 UITextField 的 delegate 设置成当前的 ViewController,
// 然后在 ViewController.m 里添加下面一个代理方法:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
// 如果有多个文本框需要输入, 希望点`Return`跳到下一个, 就给下一个文本框的 outlet 发送 becomeFirstResponder 消息即可.

NSURLConnection 发送异步请求
// 代码如下:
[NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]
queue:[[NSOperationQueue alloc] init]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
//异步请求完成后的操作
}];
// 如果要在 completionHandler 中更改界面, 需要用以下代码:

UITextField 或 UITextView 中禁用部分指定操作（如复制、剪切）
// Create a subclass of `UITextField` or `UITextView`,
// and override the `canPerformAction:withSender:` method like following:
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == @selector(copy:))
return NO;
return [super canPerformAction:action withSender:sender];
}
