xcode arc 下使用 block警告 Capturing [an object] strongly in this block is likely to lead to a retain cycle” in ARC-enabled code
解决方法:
方法一:
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:Api]]; __block ASIHTTPRequest *brRequest = request; [request setCompletionBlock:^{
id json = [NSJSONSerialization JSONObjectWithData:[brRequest responseData] options: error:Nil];
//NSLog(@"%@",json);
NSLog(@"completed"); }]; [request setFailedBlock:^{
NSLog(@"%@",[brRequest error]);
}]; [request startAsynchronous];
方法2:
// //方式二
// __weak ASIHTTPRequest *werRequest = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:api]];
// [werRequest setCompletionBlock:^{
// id json = [NSJSONSerialization JSONObjectWithData:[werRequest responseData] options:0 error:Nil];
// NSLog(@"%@",json);
//
// }];
//
// [werRequest setFailedBlock:^{
// NSLog(@"%@",[werRequest error]);
// }];
//
// [werRequest startAsynchronous];
