我无法通过NSJSONSerialization序列化负整数。
目标-C:
NSMutableDictionary *sendData = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@480, @"width",
@800, @"height"
@-10, @"value1",
@10, @"value2", nil];
NSError *error = nil;
NSData *dataJSon = [NSJSONSerialization dataWithJSONObject:sendData options:0 error:&error];
NSLog(@"sendData\n %@ \n\n", [sendData description]);
记录
sendData{
width = 480; // int
height = 800; // int
value1 = "-10"; // string. Not integer!!
value2 = 10; // int
}
如何序列化负整数?
最佳答案
您是正确的,一切都很好。那只是字典-描述是令人误解的。
NSMutableDictionary *sendData = [NSMutableDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:-10], @"value1",
[NSNumber numberWithInt:10], @"value2", nil];
NSError *error = nil;
NSData *dataJSon = [NSJSONSerialization dataWithJSONObject:sendData options:0 error:&error];
NSLog(@"sendData\n %@ \n\n", [sendData objectForKey:@"value1"]);
