(1) Effect

(2) free source code download

Group Buying page + iOS source code + Head Advertisement carousel + more loading at the bottom

Download plist data files and image resources (if the operation prompts that data is missing, you can drag the data plist and other files to overwrite the original one)

(3) Supplement

In the source code, there is a flaw: because it is a single thread, when the page is dragged up or down, the image carousel will stop. Therefore, we need to take into consideration the problem. The solution adds the timer to the current runLoop.

Add a line of code to the playOn method of WPTgHeaderView. m:

-(Void) playOn {timer = [NSTimer scheduledTimerWithTimeInterval: 2.0 target: self selector: @ selector (nextImage) userInfo: nil repeats: YES]; // when dragging up or down, the image can still be carousel, that is, the timer can still work. Because it is a single thread, you need to add the timer to the current runLoop [[nsunloop currentRunLoop] addTimer: timer forMode: nsunloopcommonmodes];}
