1、写一个String类的分类：如下所示
import UIKit
extension String {
var containsEmoji: Bool {
for scalar in unicodeScalars {
switch scalar.value {
case 0x1F600...0x1F64F, // Emoticons
0x1F300...0x1F5FF, // Misc Symbols and Pictographs
0x1F680...0x1F6FF, // Transport and Map
0x1F1E6...0x1F1FF, // Regional country flags
0x2600...0x26FF, // Misc symbols
0x2700...0x27BF, // Dingbats
0xFE00...0xFE0F, // Variation Selectors
0x1F900...0x1F9FF, // Supplemental Symbols and Pictographs
127000...127600, // Various asian characters
65024...65039, // Variation selector
9100...9300, // Misc items
8400...8447: // Combining Diacritical Marks for Symbols
return true
default:
continue
}
}
return false
}
}
2、使用如下
let str = "表情😀"
if str. containsEmoji == true {
print("该字符串包含表情")
}
