IOS JSON to PLIST
Read JSON data from the file and write it to the file. The implementation code is as follows:
NSString *path = @"/Users/android_ls/Desktop/city_province.json"; NSArray *array = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfFile:path] options:NSJSONReadingMutableLeaves error:nil]; [array writeToFile:@"/Users/android_ls/Desktop/city_province.plist" atomically:YES];
Note: The above code snippet must be run on the simulator
If the above code snippet is changed to the following:
NSString *path = [[NSBundle mainBundle] pathForResource:@"city_province.json" ofType:nil]; MyLog(@"path = %@",path); NSArray *array = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfFile:path] options:NSJSONReadingMutableLeaves error:nil]; NSString *newPath = [NSString stringWithFormat:@"%@%@",[[NSBundle mainBundle] bundlePath],@"/city_province.plist" ]; MyLog(@"newPath = %@", newPath); [array writeToFile:newPath atomically:YES];
Note: Before testing, copy the city_province.json file to the Supporting Files directory.
Put it on the simulator to test, print the LOG as follows:
2014-10-15 22:38:03.224 YWBAPP[11578:60b] path = /Users/android_ls/Library/Application Support/iPhone Simulator/7.1/Applications/0909D47B-A2B6-467D-9E19-396A73383D8A//city_province.json 2014-10-15 22:38:03.225 YWBAPP[11578:60b] newPath = /Users/android_ls/Library/Application Support/iPhone Simulator/7.1/Applications/0909D47B-A2B6-467D-9E19-396A73383D8A//city_province.plist
Put it on the real machine to test, print the LOG as follows:
2014-10-15 22:40:59.796 YWBAPP[3127:60b] path = /var/mobile/Applications/4DAB17CC-F307-4D1B-B78D-80E9B5B4343F//city_province.json 2014-10-15 22:40:59.805 YWBAPP[3127:60b] newPath = /var/mobile/Applications/4DAB17CC-F307-4D1B-B78D-80E9B5B4343F//city_province.plist
The path is correct, but the file cannot be found in the corresponding directory.
