iOS 正則表達式判斷UITextField是否為全漢字阳懂，全字母梅尤，全數(shù)字，數(shù)字和字母
判斷全漢字（這個問題苦惱了我很久岩调，現(xiàn)在很方便巷燥，幾行代碼就搞定）：
if ([self deptNameInputShouldChinese]) {
[DemonAlertHelper showToastWithMessage:@"只能是中文"];
return;
}
調用這個方法就可
pragma mark--
pragma mark 輸入中文
(BOOL) deptNameInputShouldChinese
{
NSString *regex = @"[\u4e00-\u9fa5]+";
NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex];
if (![pred evaluateWithObject:inputTextField.text]) {
return YES;
}
return NO;
}
判斷全數(shù)字：(BOOL) deptNumInputShouldNumber
{
NSString regex =@"[0-9]";
NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex];
if (![pred evaluateWithObject:inputTextField.text]) {
return YES;
}
return NO;
}
判斷全字母：(BOOL) deptPassInputShouldAlpha
{
NSString regex =@"[a-zA-Z]";
NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex];
if (![pred evaluateWithObject:inputTextField.text]) {
return YES;
}
return NO;
}
判斷僅輸入字母或數(shù)字：(BOOL) deptIdInputShouldAlphaNum
{
NSString regex =@"[a-zA-Z0-9]";
NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex];
if (![pred evaluateWithObject:inputTextField.text]) {
return YES;
}
return NO;
}
