.json文件的数据获取需要通过赋值NSData,再通过NSJSONSerialization 方法将NSData数据转成NSArray 或NSDictionary进行使用。
.plist文件的数据可以直接进行访问。
//获取本地location.json文件内容
@property (nonatomic, strong) NSArray *locData;
- (NSArray *)locData {
if (!_locData) {
NSData *JSONData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"location" ofType:@"json"]];
NSArray *dataArray = [NSJSONSerialization JSONObjectWithData:JSONData options:NSJSONReadingAllowFragments error:nil];
NSMutableArray *newArray = [NSMutableArray array];
for (NSDictionary *dict in dataArray) {
XCFLocation *loc = [XCFLocation locationWithDict:dict];
[newArray addObject:loc];
}
_locData = newArray;
}
return _locData;
}
//获取本地keywords.plist文件内容
@property (nonatomic, strong) NSArray *hotSearchWords;
- (NSArray *)hotSearchWords {
if(!_hotSearchWords) {
NSDictionary *dataDict = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"keywords"ofType:@"plist"]];
NSArray *array = [NSArray arrayWithArray:dataDict[@"content"][@"keywords"]];
NSMutableArray *mArray = [NSMutableArray array];
for (NSString *word in array) {
[mArray addObject:word];
}
_hotSearchWords = mArray;
}
return _hotSearchWords;
}
//写入.plist文件
NSString *filename = [[NSBundle mainBundle] pathForResource:@"keywords" ofType:@"plist”];
NSDictionary *dataDict = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"keywords" ofType:@"plist"]];
[dataDictsetObject:@"add some content"forKey:@"c_key"];
[dataDict writeToFile:filename atomically:YES];
