(Proficient in iOS development) Chapter 1 example code thoroughly clear warnings In the previous article, we solved a small defect in The main warning content is to use the discarded UIAlertView object and its callback method. Next we will try to clear all these warnings. First, refactor the Alert button callback method into a new method: -(void)createTinyPixFile:(NSString*)fn{ if (!fn || fn.length == 0

Yesterday interview, was asked a code refactoring, directly stunned ...Come back a little bit to see, the code refactoring has a little understanding ... is to let your own code has a better structure, more concise and easy to read it is a way to improve the quality of code it!

Bottom,left, right margin constraints, the constraint value is 20, the implementation of the effect is as follows:Implementation step four: Set the relative distance between the three view, check VIEW2 set lift constraints back to find there are two options, a value is smaller, a value is larger, the default is the value is smaller, the value of the smaller option is relative view1 distance value is relatively super View distance, where the default constraint values are used:Using the same meth

IOS Singleton mode (design mode 1) The Singleton mode is a common software design mode. Its core structure only contains a special class called Singleton class. The Singleton mode ensures that there is only one instance in a class in the system and the instance is easy to access, so as to conveniently control the number of instances and save system resources. If you want to have only one class object in the

1. Difference between shallow copy and deep copy? What is the difference between shallow replication and deep replication? BytesAnswer: copy the pointer to the object instead of the referenced object. Deep copy: copy the referenced object itself. Copying means that I have an A object.

Haha! Since my knowledge of apple is basically 0, everything starts from scratch and the knowledge of using MAC is also 0, so I will record some general knowledge related to using MAC, on the one hand, it is a record, and on the other hand it is shared
