感谢ios行业的同事。
方法一：
// 替换"<>"之间的字符串 为$1和$2之间的字符串 NSString *str=@"abcdeffed<12.\3>cba";
NSError* error = NULL;
NSRegularExpression* regex = [NSRegularExpression regularExpressionWithPattern:@"[^<]+(>)" options:0 error:&error];
NSString* result = [regex stringByReplacingMatchesInString:str options:0 range:NSMakeRange(0, str.length) withTemplate:@"$1$2"];
result=[result stringByReplacingOccurrencesOfString:@"<>" withString:@""];
NSLog(@"Result:%@", result);
方法二:
NSString *strrrrrrrrrr = @"abcdeffed<123>cba";
NSString *str2 = [[strrrrrrrrrr stringByReplacingOccurrencesOfString:@"<" withString:@"-"] stringByReplacingOccurrencesOfString:@">" withString:@"-"];
NSArray *arry = [str2 componentsSeparatedByString:@"-"];
NSMutableArray *newArray = [NSMutableArray array];
for (int i = 0; i < arry.count; i++) {
if (i%2 == 0) {
NSString *temp = arry[i];
if (temp.length > 0) {
[newArray addObject:arry[i]];
}
}
}
XPFLog(@" ====== %@", newArray);
NSString *string9 = [newArray componentsJoinedByString:@""];
NSLog(@"string9 : %@",string9);
