我已经阅读了stackoverflow上的几个答案，这些答案没有解决为Samsung Galaxy for Zip Code显示数字键盘的问题。
iOS会打开一个数字键盘，但三星Galaxy不会为这段代码调出数字键盘：
<input name="zipCode" type="text" pattern="\d*" required="required" title="Please enter a valid U.S. zip code">
HTML5号码输入类型无效，因为它会截断以零开头的邮政编码：
<input name="zipCode" type="number" required="required" min="0" title="Please enter a valid U.S. zip code">
这不适用于iOS或三星Galaxy，因为iOS会查找[0-9] *或\ d *作为模式：
<input name="zipCode" type="text" pattern="^\d{5}$" required="required" title="Please enter a valid U.S. zip code">
答案 0 :(得分：0)
我相信电话号码可能有效。尝试：
NSError *error;
// Recording settings
NSDictionary *settings = @{AVEncoderAudioQualityKey: @(AVAudioQualityMedium),
AVFormatIDKey: @(kAudioFormatMPEG4AAC),
AVEncoderBitRateKey: @(128000),
AVNumberOfChannelsKey: @(1),
AVSampleRateKey: @(44100),
AVLinearPCMBitDepthKey:@(8)};
// File URL
NSURL *url = [NSURL fileURLWithPath:pathToSave];//FILEPATH];
// Create recorder
recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error];
if (!recorder)
{
NSLog(@"Error establishing recorder: %@", error.localizedFailureReason);
return NO;
}
recorder.delegate = delegate;
recorder.meteringEnabled = YES;
if (![recorder prepareToRecord])
{
NSLog(@"Error: Prepare to record failed");
return NO;
}
if (![recorder record])
{
NSLog(@"Error: Record failed");
return NO;
}
