Getting Started

#import <NinePatchKit/NinePatchKit.h>
...
NSString * path = [[NSBundle mainBundle] pathForResource:@"YourNinePatchImageName" ofType:@"png"];
NinePatchImageView * imageView = [[NinePatchImageView alloc] init];
imageView.showImage = [NinePatchUtils imageWithContentsOfFile:path];

Tips

• Placement of nine-patch pictures
  • You can place nine-patch pictures in bundle, Data Set and other places besides Image Set. During the construction, all png pictures in Image Set will be optimized by implanting a CgBI chunk, and some chunks will be removed, so the format of nine-patch pictures will be damaged and cannot be parsed.
