iOS 字符串首字母大写

    NSString *dealString = @"asdasdfasdfads";
    NSString *resultString = @"";
    if (dealString.length > 0) {
        resultString = [dealString stringByReplacingCharactersInRange:NSMakeRange(0,1) withString:[[dealString substringToIndex:1] capitalizedString]];
    }
    NSLog(@"resultString = %@", resultString);

    控制台输出: resultString = Asdasdfasdfads
