Install

-------



**Manual**  

Copy the files in the folder named PullToRefreshCoreText to your project.  

Import the "UIScrollView+PullToRefreshCoreText.h"  

  

**Cocoapods**



```

    source 'https://github.com/CocoaPods/Specs.git'

    pod 'PullToRefreshCoreText', '~> 0.2'

``` 



Usage

-----



	- (void)addPullToRefreshWithPullText:(NSString *)pullText

	                       pullTextColor:(UIColor *)pullTextColor

	                        pullTextFont:(UIFont *)pullTextFont

	                      refreshingText:(NSString *)refreshingText

	                 refreshingTextColor:(UIColor *)refreshingTextColor

	                  refreshingTextFont:(UIFont *)refreshingTextFont

	                              action:(pullToRefreshAction)action;



It has 2 main texts, pulling and refreshing. 


Init function has parameters for creating this texts with its strings, text colors and fonts. 
 

Last parameter is the block function where loading code goes to. 



Alternatively I added some other init methods if you want to use same texts or fonts etc. 



	   - (void)addPullToRefreshWithPullText:(NSString *)pullText

	                                 action:(pullToRefreshAction)action;

	   

	   - (void)addPullToRefreshWithPullText:(NSString *)pullText

	                         refreshingText:(NSString *)refreshingText

	                                 action:(pullToRefreshAction)action;

	   

	   - (void)addPullToRefreshWithPullText:(NSString *)pullText

	                                   font:(UIFont *)font

	                                 action:(pullToRefreshAction)action;

	   

	   

	   - (void)addPullToRefreshWithPullText:(NSString *)pullText

	                         refreshingText:(NSString *)refreshingText

	                                   font:(UIFont *)font

	                                 action:(pullToRefreshAction)action;

	   

	   

	   - (void)addPullToRefreshWithPullText:(NSString *)pullText

	                          pullTextColor:(UIColor *)pullTextColor

	                         refreshingText:(NSString *)refreshingText

	                    refreshingTextColor:(UIColor *)refreshingTextColor

	                                   font:(UIFont *)font

	                                 action:(pullToRefreshAction)action;



Implementation

--------------



    //Create ScrollView

    self.scrollView = [[UIScrollView alloc] initWithFrame:self.view.frame];

    [self.scrollView setContentSize:CGSizeMake(self.view.frame.size.width, self.scrollView.frame.size.height + 1)];

    [self.view addSubview:self.scrollView];



    

    //add pull to refresh

    __weak typeof(self) weakSelf = self;

    [self.scrollView addPullToRefreshWithPullText:@"Pull To Refresh" pullTextColor:[UIColor blackColor] pullTextFont:DefaultTextFont refreshingText:@"Refreshing" refreshingTextColor:[UIColor blueColor] refreshingTextFont:DefaultTextFont action:^{

        [weakSelf loadItems];

    }];



One last thing: you should call the `[scrollView finishLoading]` method after the load finishes.


Otherwise you stuck in refreshing state always.
