5. The method according to claim 4, wherein the current control is an already instantiated control, and specifically comprises:
and the preset secondary cache stores the control of the instance of the current control.
6. The method according to claim 3, wherein performing a unbinding operation on each circularly dependent chain to obtain an acyclic dependent chain comprises:
for each cyclic dependency chain:
when the current control is the control which is already instantiated, searching the control which is dependent on the current control in the cyclic dependency chain according to the sequence of executing the instantiation operation along the cyclic dependency chain;
and deleting the identifier data of the current control in the dependent data set of the control, so that the control is independent of the current control.
