ios 如何判断字符串含有中文字符？
NSString *text = @"i'm a 苹果。...";
int length = [text length];
for (int i=0; i<length; ++i)
{
NSRange range = NSMakeRange(i, 1);
NSString *subString = [text substringWithRange:range];
const char *cString = [subString UTF8String];
if (strlen(cString) == 3)
{
NSLog(@"汉字:%s", cString);
}
}
NSString
*str = @
"i'm a 苹果。..."
;
for
(
int
i=0; i< [str length];i++){
int
a = [str characterAtIndex:i];
if
( a > 0x4e00 && a < 0x9fff)
NSLog
(@
"汉字"
);
}
NSString
*str = @
"i'm a 苹果。..."
;
for
(
int
i=0; i< [str length];i++){
int
a = [str characterAtIndex:i];
if
( a > 0x4e00 && a < 0x9fff)
NSLog
(@
"汉字"
);
}
