Ratingview star comment Control Learning for iOS open-source Project (1)

1 Preface

During this time, I learned the basic things of iOS, and the theory needs to be related to the actual situation. I do not want to look for several open-source project codes for research. I am suffering from technical limitations, at the beginning, we can only research and write simple controls. Today we will learn a simple control application, star rating control.

2. Details

This is a very simple control, but not a lot of it is used, so it is good as an entry-level learning material.

Code Overview:

Ratingcontrollerviewcontroller. h

#import <UIKit/UIKit.h>#import "ZYRatingView.h"@interface ZYViewController : UIViewController<RatingViewDelegate>{ZYRatingView *starView;UILabel *ratingLabel;}@property (nonatomic, retain) IBOutlet ZYRatingView *starView;@property (nonatomic, retain) IBOutlet UILabel *ratingLabel;-(IBAction)clearRating:(id)sender;-(void)ratingChanged:(float)newRating;@end

Ratingcontrollerviewcontroller. m

The proxy is viewcontroller [starview setimagesdeselected: @ "0.png" partlyselected: @ "1.png" fullselected: @" 2.png" anddelegate: Self]; // set the score [starview displayrating: 1.5];} // clear the score-(ibaction) clearrating :( ID) sender {[starview displayrating: 0.0];} // implement proxy method-(void) ratingchanged :( float) newrating {// display ratinglabel. TEXT = [nsstring stringwithformat: @ "rating is: % 1.1f", newrating];}
