I am getting an array with null value. Please check the structure of my array below:
( "< null>" )
When I'm trying to access index 0 its crashing because of
-[NSNull isEqualToString:]: unrecognized selector sent to instance 0x389cea70
Currently its crashing because of that array with a crash log:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull isEqualToString:]: unrecognized selector sent to instance 0x389cea70' *** First throw call stack: (0x2d9fdf53 0x3820a6af 0x2da018e7 0x2da001d3 0x2d94f598 0x1dee57 0x1dfd31 0x302f598d 0x301a03e3 0x3052aeed 0x3016728b 0x301659d3 0x3019ec41 0x3019e5e7 0x30173a25 0x30172221 0x2d9c918b 0x2d9c865b 0x2d9c6e4f 0x2d931ce7 0x2d931acb 0x3262c283 0x301d3a41 0xabb71 0xabaf8) libc++abi.dylib: terminating with uncaught exception of type NSException
arrays can't contain nil.
if array?. isEmpty == false { print("There are objects!") }
In addition to the provided initializers, such as initWithObjects: , you can create an NSArray object using an array literal. NSArray *array = @[someObject, @"Hello, World!", @42]; In Objective-C, the compiler generates code that makes an underlying call to the arrayWithObjects:count: method.
id object = myArray[0];// similar to [myArray objectAtIndex:0] if(![object isEqual:[NSNull null]]) { //do something if object is not equals to [NSNull null] }
if (myArray != (id)[NSNull null])
OR
if(![myArray isKindOfClass:[NSNull class]])
