Detailed explanation of the example of dictionary to string in IOS development
In actual development requirements, sometimes we need to package certain objects and finally splice them into parameters
For example, we package all parameter dictionaries into a string and splice them into the parameters
Idea: Use the system JSON serialization class, NSData as the intermediate bridge
//1. Convert the dictionary to string (JSON format), using NSData as a bridge;
NSDictionary *dic = @{@"name":@"Lisi",@"sex":@"m",@"tel":@"1770"};
//Convert string to NSData
NSData *data = [NSJSONSerialization dataWithJSONObject:dic options:NSJSONWritingPrettyPrinted error:nil];
//Create string object with NSData
NSString *dicStr = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"Dictionary conversion to string is %@",dicStr);
The result is a JSON string:
{
"name" : "Lisi",
"sex" : "m",
"tel" : "1770"
}
