In iOS 16+, when the NSData *data ranges between 0 and 255, the int16_t buff retrieves values not within the range of 0 to 255, but rather 29440 to 29696.
- (void)system:(id)system features:(void (^)(NSArray*))features
{
[self read:TAPropertyTypeAvailableFeatures system:system handler:^(NSDictionary* data, NSError* error){
NSArray* datas = [data objectForKey:@"value"];
NSMutableArray* numbers = [[NSMutableArray alloc] init];
for(NSData* data in datas)
{
int16_t buff;
[data getBytes:&buff length:sizeof(buff)];
NSNumber* number = [NSNumber numberWithInteger:buff];
[numbers addObject:number];
}
features(numbers);
}];
}
When I upgraded my MacBook to 14.1.2 and Xcode to 15.0.1, I encountered an issue with this function that I rebuilt.
In iOS 16+, when the NSData *data ranges between 0 and 255, the int16_t buff retrieves values not within the range of 0 to 255, but rather 29440 to 29696.
However, in iOS 15, it still remains between 0 and 255.
This problem never occurred before. Changing int16_t to int resolves the issue.
What is causing this issue?
Is it possible to continue using int16_t without encountering this problem?
