ios - Adding images to UIScrollview with horizontal infinity style scrolling -
so i'm doing first uiscrollview placing resized images it, when end of first set of results , go add 2nd set etc., view resets start. i'm not sure if it's adding images, x value being counted forward correctly, uiscrollview should resizing, can assume placing next set of images on top of old images.
what doing wrong here?
-(void)addscrollviewimages { // setup our uiscrollview self.scrollview.delegate = self; self.scrollview.pagingenabled = yes; self.scrollview.showshorizontalscrollindicator = no; self.scrollview.showsverticalscrollindicator = no; self.scrollview.contentsize = cgsizemake(self.scrollview.frame.size.width,self.scrollview.frame.size.height); // hit our server data nsstring *encodedkeywords =[self.keyword stringbyaddingpercentescapesusingencoding:nsutf8stringencoding]; self.results = [self fetchimageresults:encodedkeywords]; // loop on image results (id image in self.results) { uiimageview *imageview = [[uiimageview alloc] initwithframe: cgrectmake(self.x, 0, self.screenwidth, self.screenhight)]; nsstring *imageurl = image[@"url"]; nsdata *image = [nsdata datawithcontentsofurl:[nsurl urlwithstring:imageurl]]; // resize image device [imageview setimage:[self imagescalecroptosize:[uiimage imagewithdata:image]]]; [self.scrollview addsubview: imageview]; self.x = (self.x + imageview.frame.size.width); // resize frame width if(self.x > self.view.frame.size.width) self.scrollview.contentsize = cgsizemake(self.x, self.scrollview.frame.size.height); } } // gets json data , processes little -(nsarray*)fetchimageresults:(nsstring*)keyword { //this should quick nserror *error = nil; nsurl *apiurl = [nsurl urlwithstring:[nsstring stringwithformat:@"http://example.com/api/v1/search?q=%@", keyword]]; nsdata *jsondata = [nsdata datawithcontentsofurl:apiurl]; nsdictionary *result = [nsjsonserialization jsonobjectwithdata:jsondata options:0 error:&error]; return result[@"results"]; } // scroll index management - (void)scrollviewdidscroll:(uiscrollview *)sender { float indexnum = self.scrollview.contentoffset.x / self.scrollview.frame.size.width; if(floor(indexnum) == indexnum) { int num = (int)indexnum; nslog(@"viewing %@",self.results[num]); // if @ end, load more if(num == (self.results.count-1) ) { dispatch_async(dispatch_get_main_queue(), ^{ [self addscrollviewimages]; }); } } }
you killing not using uitableview. make uitableview prototype uitableviewcells. subclass cell, imageviewtablecell, , make property uiimageview fills size.
the rest using uitableviewdelegate , uitableviewdatasource.
