Unable to read Images from xcode project for example. drag and drop one image to xcode project, then read using following code.

__weak NSString *strTemp = [NSString stringWithFormat:@"%@/s_%@",[[NSBundle mainBundle] resourcePath],[[self.arr_gallery objectAtIndex:i]valueForKey:@"filename_larger"]];

            strTemp = [strTemp substringToIndex:[strTemp length]-3];

            strTemp = [NSString stringWithFormat:@"%@png",strTemp];

// NSString *strTemp = [[NSString alloc] initWithFormat:@"%@/s_BGP001@2x.png",[[NSBundle mainBundle] resourcePath]];

            UIImage *image;

            image = [[UIImage alloc] initWithContentsOfFile:strTemp];

            img.image = image;

            strTemp = nil;

Answer 1

Write following code.

 NSString *newStrTemp = [strTemp stringByReplacingOccurrencesOfString:@"jpg" withString:@"png"];    

Instead of this one.

strTemp = [strTemp substringToIndex:[strTemp length]-3];
strTemp = [NSString stringWithFormat:@"%@png",strTemp];
