NSArray *jsonArray; // your parsed array
NSDictionary *dict = [jsonArray objectAtIndex:0]; // there might be more of the objects and you might need to put that into a forin cycle, but for simplicity this is an example for an array with only one dictionary in it
NSArray *images = [dict objectForKey:@"images"];
NSMutableArray *links = [NSMutableArray array];
for (NSDictionary *img in images) {
[links addObject:[img valueForKey:@"source"]];
}
现在链接是您需要的 NSString 对象数组。如果需要,您还可以将它们转换为 NSURL。

好吧,您的图像数组就是[jsonObject objectForKey:@"images"]
如此循环所有这些并拍摄[loopObject objectForKey:@"source"]
,最后,不要忘记[jsonObject objectForKey:@"source"]

[yourDictionary objectForKey:@"data"]
给字典。
NSDictionary *dictionary = [yourDictionary objectForKey:@"data"]
NSArray *images = [dictionary objectForKey:@"images"];
NSMutableArray *sourceUrls = [[NSMutableArray alloc] initWithCapacity:0];
for (NSDictionary *subDictionary in images]) {
[sourceUrls addObject:[subDictioanary objectForKey:@"source"]];
}
我想这会对你有所帮助。

在您的代码中包含 SBJSON 解析器。然后在实现文件中导入SBJson.h。然后使用下面的代码。
NSMutableDictionary *responseDictionary = [yourJsonString JSONValue];
NSArray *imageArray = [responseDictionary objectForKey:@"images"];
NSMutableArray *sourceImage=[[NSMutableArray alloc]init]
for(int i=0;i<[imageArray count];i++){
{
[sourceImage appendString:[[imageArray objectAtIndex:i]objectForKey:@"source"]];
}
