这是一个有效的 json 格式。我已经使用http://jsonlint.com/并使用http://braincast.nl/samples/jsoneditor/检查了它
查看 json 值的结构。根据结构,人员标签应返回计数 2,因为它有 2 个对象,但在解析时只返回 1。我完全没有选择。请帮助各位。
这是我用来解析的代码
NSString *textPAth = [[NSBundle mainBundle] pathForResource:@"sync" ofType:@"json"];
NSError *error;
NSString *content = [NSString stringWithContentsOfFile:textPAth encoding:NSUTF8StringEncoding error:&error];
NSArray *jsonArray = [[content JSONValue] retain];
NSLog(@"JSON ARRAY %@ AND COUNT %d",[[jsonArray valueForKey:@"updates"] valueForKey:@"people"],[[[jsonArray valueForKey:@"updates"] valueForKey:@"people"] count]);
