判断ios11新增的56种emoji表情
ios11新增了56种emoji表情,对应如下:
0x1f3f4
0x1f6f7
0x1f6f8
0x1f91(f)
0x1f92(8,9,a,b,c,d,e,f)
0x1f93(1,2)
0x1f94(c)
0x1f95(f)
0x1f96(0,1,2,3,4,5,6,7,8,9,a,b)
0x1f99(2,3,4,5,6,7)
0x1f9e(0,1,2,3,4,5,6)
0x1f9d(0,1,2,3,4,5,6,7,8,9,a,b,c,d,e)
原来的emoji表情判断基本使用下面的方式:
+ (BOOL)stringContainsEmoji:(NSString *)string
{
BOOL returnValue = NO;
if (!JDUtils.validateString(string)) {
return returnValue;
}
const unichar hs = [string characterAtIndex:0];
if (0xd800 <= hs && hs <= 0xdbff) {
if (string.length > 1) {
const unichar ls = [string characterAtIndex:1];
const int uc = ((hs - 0xd800) * 0x400) + (ls - 0xdc00) + 0x10000;
if (0x1d000 <= uc && uc <= 0x1f77f) {
returnValue = YES;
}
}
} else if (string.length > 1) {
const unichar ls = [string characterAtIndex:1];
if (ls == 0x20e3) {
returnValue = YES;
}
} else {
if (0x2100 <= hs && hs <= 0x27ff) {
returnValue = YES;
} else if (0x2B05 <= hs && hs <= 0x2b07) {
returnValue = YES;
} else if (0x2934 <= hs && hs <= 0x2935) {
returnValue = YES;
} else if (0x3297 <= hs && hs <= 0x3299) {
returnValue = YES;
} else if (hs == 0xa9 || hs == 0xae || hs == 0x303d || hs == 0x3030 || hs == 0x2b55 || hs == 0x2b1c || hs == 0x2b1b || hs == 0x2b50) {
returnValue = YES;
}
}
return returnValue;
}
原来的判断:
if (0x1d000 <= uc && uc <= 0x1f77f) {
returnValue = YES;
}
只包含:0x1f3f4、0x1f6f7、0x1f6f8
只需要把0x1f9的几种加入判断种就行了。
