我试图从字典中获取特定键的值,但我得到了一个[__NSCFArray objectForKey:]: unrecognized selector sent to instance
- (void)listCaredMembersSuccessResponse:(NSDictionary *)response {
[self hideActivityView];
if ([[response valueForKey:@"status"] caseInsensitiveCompare:NSLocalizedString(@"SUCCESS", nil)] == NSOrderedSame) {
NSDictionary *mainDict = [response objectForKey:@"data"];
NSArray *detailsArray = [mainDict objectForKey:@"Text"];
[appDelegate.proxiesListArr addObjectsFromArray:[ParserManager parseListCaredMembers:detailsArray]];
} else {
[[ClassObjects sharedCenter] showCustomAlert:@"" Message:NSLocalizedString(@"PROXIES_FAILURERESPONSE", nil)];
}
这是我的 json 响应:
{"Status":"Success","data":[{"Alias":"1-0","ID":80,"Icon":"","Items":[],"Params":{},"Text”:”Text1”,”Type":"group","Width":"170"},{"Alias":"1-1","ID":8000102,"Icon":"","Items":[],"Params":{},"Text”:”Text2”,”Type":"group","Width":"170"}]}
问题是你有NSArray
而不是NSDictionary
。NSArray
的计数为 1,包含NSDictionary
。
这行是错误的
NSArray *detailsArray = [mainDict objectForKey:@"Text"];
NSArray *wrapper= [[NSJSONSerialization JSONObjectWithData:webData options:0 error:nil]objectForKey:@"data"];
for (NSDictionary *temp in wrapper) {
NSString *text=[temp objectForKey:@"Text"]; //Text may be NSString type
// THE REST OF YOUR CODE
}
更新
if ([[response valueForKey:@"status"] caseInsensitiveCompare:NSLocalizedString(@"SUCCESS", nil)] == NSOrderedSame) {
NSArray *mainDict = [response objectForKey:@"data"];
for (NSDictionary *temp in mainDict) {
NSString *text=[temp objectForKey:@"Text"]; //Text may be NSString type
// THE REST OF YOUR CODE
}
}
