Other options than NSJSONWritingPrettyPrinted?
Convert NSDictionary
to JSON NSData
with the following line:
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:answers
options:NSJSONWritingPrettyPrinted
error:&err];
And pass it to the server side, which is a PHP script. The script reads a JSON string as:
{
"A" : "1941",
"D" : "1699",
"B" : "1949",
"E" : "1823",
"C" : "1999"
}
How can I format the JSON string as 1 string like below?
{"A" : "1941", "D" : "1699", "B" : "1949", "E" : "1823", "C" : "1999"}
Is there any parameter other than NSJSONWritingPrettyPrinted
?

Quoth documentation forNSJSONWritingPrettyPrinted
;
If this parameter is not set, the most compact JSON representation is generated.
If you don't want to set any bits in the write parameter mask, just omit zero for this parameter. (Or, in Swift, an empty parameter set that looks like an empty array:. []
)

You shouldn't use it NSJSONWritingPrettyPrinted
for purposes other than debugging. You can go to options:0
(see below) to have minified JSON.
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:answers options:0 error:&err];
To test this, you can convert it to string and NSLog
it.
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
There are no other options besides NSJSONWritingPrettyPrinted
:
typedef NS_OPTIONS(NSUInteger, NSJSONWritingOptions) {
NSJSONWritingPrettyPrinted = (1UL << 0)
} NS_ENUM_AVAILABLE(10_7, 5_0);
