UIControls + Blocks

UIControls+Blocks, is the dead-simple, missing link between iOS interface controls and objective-c blocks. No more delegates and useless methods, just blocks!

How To Use?

There's two ways you can use all this great stuff:

1. Include all the files in your project/target and add the main header: #import "UIControls+Blocks.h"
2. Or just include the controls you want like: #import "UIButton+Blocks.h"

Examples

UIButton+Blocks

Handle Control Events

[myButton handleControlEvent:UIControlEventTouchDown withBlock:^{
	NSLog(@"You pressed my button!");
}];

---

UITableView+Blocks

Set Number of Rows

No more numberOfRowsInSection nonsense:

[myTable setNumberOfRows:1];

Want multiple sections? No problem! Just pass an array of row values. Here's 3 sections with 2 rows each:

[myTable setNumberOfRowsInSections:@[@2,@2,@2,]];

Cell Drawing

The cellForRowAtIndexPath alternative is handleCellCreationWithBlock like so:

[myTable handleCellCreationWithBlock:^UITableViewCell *(UITableView *tableView, NSIndexPath *indexPath){
	static NSString *CellIdentifier = @"Cell";
	UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
	if (cell == nil)
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    NSLog(@"Creating cell for section: %i and row: %i", [indexPath section], [indexPath row]);
    cell.textLabel.text = @"";
    return cell;
}];

Cell Selection

The didSelectRowAtIndexPath alternative is handleCellSelectionWithBlock like so:

[myTable handleCellSelectionWithBlock:^void(UITableView *tableView, NSIndexPath *indexPath){
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    NSInteger row = [indexPath row];
    NSLog(@"Selected cell: %i",row);
}];

UIPickerView+Blocks

Set Row Titles

The numberOfRowsInComponent and titleForRow alternative is setTitles. You must pass in a two dimensional array, like so:

[myPicker setTitles:@[ @[@"Component1Row1",@"Component1Row2"], @[@"Component2Row1",@"Component2Row2"] ]];

Row Selection

The didSelectRow alternative is handleSelectionWithBlock like so:

[myPicker handleSelectionWithBlock:^void(UIPickerView *pickerView, NSInteger row, NSInteger component){
	NSLog(@"You pressed row: %i in component: %i!", row, component);
}];
