所以,如果你有另外一个对象叫做myAppObject拥有方法,可以访问数组对象,以及插入对象到一个数组,你可以把前面的例子写成如下的样子: [[myAppObject getArray]insertObject:[myAppObject getObjectToInsert]atIndex:0]; 虽然前面的例子都是传递消息给某个类的实例,但是你也可以传递消息给类本身。当
objc_setAssociatedObject(array, &overviewKey, nil, OBJC_ASSOCIATION_ASSIGN); 其中,被关联的对象为nil,此时关联策略也就无关紧要了。 使用函数objc_removeAssociatedObjects可以断开所有关联。通常情况下不建议使用这个函数,因为他会断开所有关联。只有在需要把对象恢复到“原始状态”的时候才会使用这个函数。 7.3.4...

Durable subscriptions allow clients to assign a durable name to a subscription when it is created. Doing this causes the NATS Streaming server to track the last acknowledged message for that clientID + durable name, so that only messages since the last acknowledged message will be delivered to ...
You can always assign its value to a local variable with the narrower type, if necessary, after you enter the function. Watch out for the use of id's in prototypes that may be affected by preprocessing. Consider the following example: ...
Toggle a bit. If bit is 0 change to 1; if bit is 1 change to 0. Also known as a complement function. void bit_array_toggle_bit(BIT_ARRAY* bitarr, bit_index_t b) Assign a value to a bit. Ifc != 0then set bit; otherwise clear bit. ...
When an array name is used by itself, the array’s address is returned. We can assign this address to a pointer as illustrated below: int vector[5] = {1, 2, 3, 4, 5}; int *pv = vector; The variable pv is a pointer to the first element of the array and not the array itself...
See Section 4.12, Connecting an Expansion Unit to an Existing RAID Array for more information. Caution - When connecting expansion units to a RAID array, always connect channel 2 of the RAID array to the A channel of the expansion units, and connect channel 3 of the RAID array to the B ...
