📝InputKit, an Elegant Kit to limits your input text, inspired by BlocksKit, written in both Objective-C & ⚡️Swift.

在设置了limitNumber后监听文本内容的变化会出现长度比limitNumber多一个的情况，虽然TextField现实的内容只有limitNumber个字符
使用kTXLimitedTextFieldChineseOnlyRegex ，不能输入中文
static let inputKitDidChangeInputText: Selector = Selector(("inputKitDidChangeInputText:"))
Version: InputKit.swift-1.1.10
目前使用的是Swift3.x
在 Swfit3.x 版本的 InputKit-1.1.10 release 版本的 SwfitDemo里面，如果不设置
textField.delegate = self的话，无法进行输入限制，OC版是可以不设置delegate的
根据苹果API注释
- (void)textFieldDidEndEditing:(UITextField *)textField reason:(UITextFieldDidEndEditingReason)reason NS_AVAILABLE_IOS(10_0);
// if implemented, called in place of textFieldDidEndEditing:
建议作以下修改，这样才能遵循苹果原来的代理调用顺序，否则真正代理只实现了textFieldDidEndEditing的时候并不能被调用。
- (void)textFieldDidEndEditing:(UITextField *)textField reason:(UITextFieldDidEndEditingReason)reason NS_AVAILABLE_IOS(10_0) {
id realDelegate = self.realDelegate;
if (realDelegate) {
if ([realDelegate respondsToSelector:@selector(textFieldDidEndEditing:reason:)])
[realDelegate textFieldDidEndEditing:textField reason:reason];
else if ([realDelegate respondsToSelector:@selector(textFieldDidEndEditing:)])
[realDelegate textFieldDidEndEditing:textField];
}
}
(void)viewDidLoad {
[super viewDidLoad];
TXLimitedTextField *textField = [[TXLimitedTextField alloc] initWithFrame:CGRectMake(20, 200, 100, 30)];
textField.backgroundColor = [UIColor blueColor];
// Of course, you can custom your field
textField.limitedType = TXLimitedTextFieldTypeCustom;
// you can also set the property in this type. It limits the max number of characters that you input
textField.limitedNumber = 10;
// limitedRegExs is a type of array argument that you can via it, and pass your regular expression to TXLimitedTextField. kTXLimitedTextFieldChineseOnlyRegex is a constant that define in TXMatchConst.h file. it's represent that only Chinese characters can be inputted.
textField.limitedRegExs = @[kTXLimitedTextFieldChineseOnlyRegex];
[self.view addSubview:textField];
// Do any additional setup after loading the view, typically from a nib.

输入 emoji 表情时，出现异常：
假设限制输入 10 个字符, 第 10 个字符如果输入是 emoji , 则 emoji 显示异常，如图。
textField.limitedSuffix = 0
会显示整数+小数点
let kLimitedTextCarIDRegex = "(^[0-9]{15}$)|([0-9]{17}([0-9]|X)$)"
textField.limitedRegEx = MatchConstant.Name.kLimitedTextCarIDRegex
textField.limitedType = .custom
输入框什么都不能输入，这种情况应该咋用啊？
swift 4.0 使用 LimitedTextField时 添加delegate 无效
Thread 1: Simultaneous accesses to 0x7ff41c812b18, but modification requires exclusive access
set {
limitedDelegate = LimitedTextViewDelegate(realDelegate: newValue)
super.delegate = limitedDelegate
}
能否添加金额输入的千位分隔符
使用xib.但是出错:
Unknown class LimitedTextField in Interface Builder file.
小写转大写可以支持吗？应该在哪改
Return button on keyboard does not work because we check for wrong selector textFieldShouldClear in textFieldShouldReturn
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
var flag = true
if let realDelegate = self.realDelegate, realDelegate.responds(to: #selector(textFieldShouldClear(_:))) {
flag = realDelegate.textFieldShouldClear(textField)
}
return flag
}textFieldDidEndEditing:reason: 这个selector
TXLimitTextField is cool, thanks for saving me from struggling.
one question as the issue title.
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text;
假如在真正的代理里执行以上方法时把textView.text=nil，再执行以下方法进行匹配就会出错
BOOL flag = YES;
id realDelegate = self.realDelegate;
if (realDelegate && [realDelegate respondsToSelector:@selector(textView:shouldChangeTextInRange:replacementText:)])
flag = [realDelegate textView:textView shouldChangeTextInRange:range replacementText:text];
int matchResult = YES;
if ([textView isKindOfClass:[TXLimitedTextView class]]) {
TXLimitedTextView *limitedTextView = (TXLimitedTextView *)textView;
NSMutableString *matchStr = [NSMutableString stringWithString:textView.text];
所以不管TXLimitedTextView还是TXLimitedTextField，在匹配正则时应该判断.text是否为空。
