我想用’.’显示小数点.在基于cordova的应用程序中的本机应用程序使用的左角.
我已经看到很多线程使用私有API等,但我想要一个可以提交应用程序商店的解决方案.任何帮助表示赞赏.
我已经尝试过 this 线程的东西.
以下是我的修改,
@protocol TSPingPong <NSObject>
- (void) ts_pong: (id) sender;
@end
@interface NSObject (TSPingPong)
@end
@implementation NSObject (TSPingPong)
- (void) ts_ping: (id) sender
{
if ( [sender respondsToSelector: @selector(ts_pong:)] )
{
[sender performSelector: @selector( ts_pong: ) withObject: self ];
}
}
@end
@interface ViewController ()
@property (weak, nonatomic) IBOutlet UIWebView *webView;
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: @selector(keyboardWillAppear:)
name: UIKeyboardWillShowNotification
object: nil];
NSString* html = @"<br><br><br><form action=''> " \
"First name: <input type='text'><br> " \
"Last name: <input type='text'><br>" \
"<input type='submit' value='Submit'> " \
"</form>";
[_webView loadHTMLString: html
baseURL: nil];
}
- (void) keyboardWillAppear: (NSNotification*) n
{
// the keyboard is about to appear!
// play pingpong with the first responder so we can ensure it has a keyboardAppearance method:
[[UIApplication sharedApplication] sendAction: @selector( ts_ping:) // added via category extension
to: nil // to: the first responder
from: self // "sender"
forEvent: nil];
}
- (void) ts_pong: (id) sender
{
// sender is the first responder. Happens to be undocumented "UIWebBrowserView" in this case.
// if it doesn't have it's own keyboardAppearance method then let's add one:
if ( ![sender respondsToSelector: @selector(keyboardAppearance)] )
{
Method m = class_getInstanceMethod( [self class], @selector( keyboardAppearanceTemplateMethod ) );
IMP imp = method_getImplementation( m );
const char* typeEncoding = method_getTypeEncoding( m );
class_addMethod( [sender class], @selector(keyboardAppearance), imp, typeEncoding );
}
if ( ![sender respondsToSelector: @selector(keyboardType)] )
{
Method m1 = class_getInstanceMethod( [self class], @selector( keyboardTypeTemplateMethod ) );
IMP imp1= method_getImplementation( m1 );
const char* typeEncoding1 = method_getTypeEncoding( m1 );
class_addMethod( [sender class], @selector(keyboardType), imp1, typeEncoding1 );
}
}
- (UIKeyboardAppearance) keyboardAppearanceTemplateMethod
{
return UIKeyboardAppearanceDark;
}
- (UIKeyboardType)keyboardTypeTemplateMethod
{
return UIKeyboardTypeDecimalPad;
}
我能够让键盘外观变暗但不是我想要的键盘类型.

最佳答案 在你的html字符串中尝试这个
<input type="tel"></input>
要么
