3.具体使用
#import "ViewController.h"
#import "DGCustomStatusBar.h"
@interface ViewController ()
@property (nonatomic, strong)DGCustomStatusBar *statusBar;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)btn:(id)sender {
[self.statusBar setBackgroundColor:[UIColor redColor]];
[self.statusBar setTextColor:[UIColor whiteColor]];
[self.statusBar setTextAlignment:NSTextAlignmentCenter];
[self.statusBar showStatusWithMessage:@"分享成功"];
}
- (DGCustomStatusBar *)statusBar {
if (_statusBar == nil) {
_statusBar = [[DGCustomStatusBar alloc] init];
}
return _statusBar;
}
